I'm having the WORST time trying to germ. cacti seeds
    #7937146 - 01/26/08 08:12 PM (16 years, 6 days ago)

I have some cacti seeds. I've tried germing them before with directions found on the internet but to no avail. Can some one please help me? Pictorial of this process would be good because sometimes it sounds confusing in the directions.

Its pretty easy stuff man. Heres what i do.

Fill a small pot with pre-made cactus soil bought at Home Depot. water it and allow it to drain well for about an hour.

Then put the seeds just barely below the surface, covering them just just a dusting of soil.

Then cover with saran wrap and sit it underneath a light. I poke a couple of holes in the saran wrap to allow some fresh air to get in and out, I also remove the saran wrap occasionally to get some more air circulation.

Im getting ready to start a new lot of seeds here in the next week or so. I hope I could be of some help. Keep them out of direct sunlight.

if you want a 100% fool proof way try this...its good for short term but you will need to transplant or fertilize soon. 

fill container with fine sharp washed sand (dry).  spray the shit out of it (make it slightly moist right through) and keep it even on the surface.  place seeds on surface (dont bury).  place ceran wrap or other see through stuff over the container to keep humidity at 100%.  place under a couple flouros lights and above 20C.  seeds should sprout in 1-2 weeks :smile:  never fails.

after that it depends more on species.  and sand has no nutrients, so some ferts will be needed....or you can play with different mixes and place 1 cm of same sand on surface for same effect.

One of the better guides is from M S Smith, it can be found here

Starting from Seed
For the non-professional cactus lover starting cacti from seed can be a daunting task, especially for those without a greenhouse and experience. But growing these beautiful specimens of the plant kingdom should not be limited to those who are mass producers. Everyone should have a chance to start their own cacti from seed and slowly watch them as they grow and form into mature specimens. With the right resources and techniques the cactus enthusiast should find success, even if that is within a well lit closet.
Seeds and Soil:
Of course first thoughts must be given to what seeds to grow. There are a number of very reputable cactus plant and seed dealers, my own favorite being Mesa Garden of Belen, New Mexico. This company has thousands of different species of seed to choose from. Mesa Garden, and many other seed sellers, can be located at the Cactus and Succulent Plant Mall home page at cactus-mall.com.

Soil choice among the professionals can be quite an intricate endeavor. Many cacti have very specific ecosystems that they have evolved in, but until you become much more involved in cacti care you can simply use the general cactus soil that can be purchased from your local nursery or garden center. If you are looking for a quality general purpuse soil I would recommend ordering from Bob Smoleyþs GardenWorld, or many of the other cacti dealers found at the Plant Mall. Many professionals are now using mixes with 50% pumice with good results, but a general mix could consist of 2/3 potting mix to 1/3 pumice.

Getting Started:
Besides the seed and soil other needed supplies are small plastic pots, a regular sized spoon, 2 deep microwavable bowls with lids (preferably glass, one large and one small), a set of tweezers, a can of disinfectant spray, a bottle of bleach, and some ziplock baggies. I would also recommend that only distilled water be used for soaking the soil and any future misting of the soil or seedlings.

Getting the soil ready and killing off all contaminates is the first step. Make an estimate of how much soil is going to be needed to fill the number of pots that are going to be used (remember, seeds should be set in the soil no less that one half apart, but an inch is best). Take the soil and put it in the large glass bowl and slowly add distilled water and mix till it is minimally wet, trying to eliminate all dry spots. The soil should not be so wet as to make it difficult to work with. Microwave for about one minute for each cup of soil. The steam created through the heating should be enough for sterilization. Use the small glass bowl to do the same procedure with sifted soil, but this time use only about 1/4 the original soil amount. This will be the soil topping for the pots and allow for the seed roots to dig in. After both containers of soil are sterilized let them cool. I recommend letting it cool with the lids on since it will help the soil avoid picking up airborne spores. This may of course take some time, so get cleaning.

Disinfect all the pots and tools by placing them in the sink with a gallon of warm water and a tablespoon or two of bleach. Let them sit for a while. If they are previously used they should be scrubbed with a clean unused sponge, being careful to remove all dirt and mineral buildup. This step will most likely save you from the horror of fungus engulfing your seeds and seedlings. Many simply avoid this step by using a fungicide in the soil, but often this will lessen seed germination rates, something that the closet cactus grower, with few seeds, cannot afford. Finish up by using the disinfectant on the counter top and placing the clean pots and tools out to dry on a clean towel. I am of course trying to stress that all items used the process, from towels to tweezers, need to be thoroughly clean and free of mold and fungus spores, etc.

An easier way to sterilize the soil is possible and quite handy if you are just sowing a small number of species. Simply put the soil in the pots as described below (but without the seeds) and microwave for an appropriate amount of time. Of course be sure that you do not cook them to long, leading the plastic to melt. I generally will put the pots in a large ziplock baggy that is partially closed, thereby lessening the dissipation of the soils moisture content. Then you can just let the soil cool a bit in this large bag, remove and sow, and then place into smaller bags for the germination.

Sowing the Seed:
Once the fine topsoil is ready, being slightly warm (80 to 85 degrees), start by filling each pot full with regular soil and then with a very thin layer of sifted soil on top of that. I personally use square 2.5þ (6 cm) plastic pots. Gently press the soil down with your spoon, but not too much, it needs to stay rather loose. Give a spraying from a misting bottle to settle and even out the top layer of soil. Make sure the soil is relatively wet but in no way sopping wet. Now just take your tweezers and place the seeds on the soil and press them halfway into the soil. Give about an inch between seedlings as you should probably keep them in these containers for at least a year.

Now you are ready to bag them up. Two 2.5" pots fit perfectly into a small ziplock. The trick in bagging them is to make the bag like a tent. This will cause the condensation buildup within the bag to run down the sides and collect at the base of the pots, possibly to be sucked back into the pots through the bottom holes. If a horizontal ceiling is above the pots droplets of condensation may fall directly on top of the newborn seedlings, often displacing the seedlings or causing them to rot easier. The easiest way to make such a tent is to place the pots directly on the crease that is at the bottom of the bags. This would mean the ziplock is directly above the pots.

Creating the Right Environment - Heat and Light:
Now that the seeds are bagged up itþs important to create the right growing environment of heating and lighting. This is possibly the most critical aspect of growing your own cacti from seed. My own method is to place the baggies onto a reptile heating pad that can be purchased from a pet store. I have forgotten the brand I use, but it is very thin with a clear lamination on it. There are a couple different sizes available, but they are rather expensive, approximately $40 for the larger one. You may want to place a small thermometer (sterilized) within one of the bags to make sure the internal temperature does not get excessive. Best germination is at about 80 to 85 degrees, but a night temperature around 65 to 70 degrees is also necessary. I simply have my heating pads and lights on a timer. A 14 to 16 hour cycle of light and heat is good. Dependent upon what type of lighting you use, its heat levels, and the environment in which the baggies will be placed, you may not need heating pads. I start my own seeds in the unheated basement of my house which usually will run about 65 degrees for the duration of the winter, having sown my seeds in the Fall so that they will be ready to acclimatize to natural conditions in the Spring.

For lighting I use two 40 watt 4' long shop lights with two florescent tubes. These are elevated about 1/2' to 1' above the seed containers. This is usually fine for the germination phase but may turn out to be too much light for best growth. Many people believe in putting the lights upwards of a couple inches from the soil level, but I have found this is not always necessary. It must be kept in mind that though cacti are typically desert plants they germinate and have much of their initial growth in cracks and crevices in the soil or under the shade of other plants. A clear sign that there is too much light is that the seedlings will stop growing and get a reddish/brown color. If this occurs you can use cheesecloth to lay over the bags as needed. Germination should take anywhere from a week to nearly a month, so be patient and avoid opening the baggies and letting in contaminates.

After about two or three months you can remove the pots from the baggies and keep them under the lights and on the heating pad cycle. Some people have been known to keep the pots in the bag for up to a year. If you find it necessary reapply the cheesecloth as needed once removed from the bag. If you begin to notice seedlings dying off after they have germinated make sure to remove the pots from the bags and allow the soil to dry out some, then follow the watering directions given below, but with added fungicide.

One additional measure I take to help recreate a natural environment indoors is to add a small fan to my timing system. I place the fan directly above the cacti on low and allow it to blow gently throughout the area of my exposed cacti. Not only will this help limit any fungus and green mold growth, but it will also help with the all too common gnat problem. Another way to limit fungus, gnats, as well as retain soil moisture, is to apply a layer of desert sand or small gravel around the seedlings once they are large enough.

Watering:
Once the new seedlings are out of the baggies watering will become important. Seedlings will need more water than mature cacti, but they also stand a better chance of getting root rot. I personally recommend that the top layer of soil should come close to being dry before re- watering. When watering is needed the pots should be placed in a dish of room temperature water, allowing the water to rise through the bottom till the topsoil is moist. One can also regularly apply a fine mist with a water bottle. Distilled water produces healthier seedlings than tap water, but rain water is the best for watering as it contain trace minerals. If you decide to use a top cover it may be necessary to learn how to use pot weight as an indicator of watering time. Do this by learning the weight of the pots when fully watered. When the pot becomes noticeably lighter be sure to water. This is also a good technique for checking adult plants as well which might have rock cover.

Though my technique does not often afford rapid growth it should lessen the chances for rot, thereby securing that the small closet cacti grower has his or her limited amount of seed succeed. Following the directions of a good 1-7-6 fertilizer such as Sudbury Cactus Juice may possibly increase survival rates by strengthening the plants natural defenses. As with any cacti fertilizer it is necessary that they be fed from the bottom only, otherwise mineral deposits will built up on the cacti themselves and can cause burns.

Growing Seedlings Outdoors:
Since I am in a northern clime I find it best to start my seedling by the above method indoors in the Fall with the anticipation that I will put them outdoors after six or more months of growth. It is very important that when placed outdoors the seedlings receive no direct sunlight, but are instead placed in a nice shady spot that gets diffused light. As with artificial lights to much sunlight will be readily recognizable by the reddening of the cacti. In this case the cacti can be moved to a less bright spot or else a shade screen can be used to cut back the light. My own method is to use replacement screening for screen doors and windows that can be cheaply purchased from your local hardware store in rolls. This screening can be doubled up until the needed level of protection is found. Such porous screening also allows for needed air circulation as well as protection from the occasional cacti eating bird. Of course one can also purchase professional growers shade screening.

Transplanting:
Once your seedlings have grown to about a half inch to an inch you might want to consider transplanting them to a new container with fresh soil. Let the soil first dry out a little. It is best that the soil is not fully wet, but also not fully dry, at which point it might harden up and encase the roots, causing the young rootlets to tear off when removing from the soil. Many species have their best growth in a relatively root bound environment so it is recommended that the cacti be little more than one inch away from the containers edges. Some cacti, especially those with tuberous roots such as Ariocarpus and Turbinicarpus also love to dive deep into the soil so be sure to provide them with adequately deep containers.

Once the seedlings are transplanted to new containers and on their way to maturity, it is time to start testing out their natural sunlight capabilities. As with all cacti, young or mature, a sudden move from shade or partial sun to full sun is not recommended. Such a sudden shift in environments can cause the plant to get unsightly sunburn marks. It is best to slowly move them into more sunlight over the period of a couple weeks, taking care to watch for browning or reddening over. Immediately move the plant back into more shade if this occurs. And remember, though your cacti received strong artificial light indoors they still might not be capable of handing a rapid shift to strong natural light.

Grafting Your Seedlings:
Now that your seedlings are large enough you might want to consider grafting. Grafting is an excellent method for increasing the growth rate of many of the clumping cacti, but is typically not done with columnar cacti. It is also used to propagate species since a graft will reach maturity quicker, thereby setting off many þpupsþ that can then be taken and grafted themselves. The principle here is to use a fast growing columnar species as a base plant and graft a slower growing clumping species onto it.

Start by selecting a nice columnar cactus for a base that is at least 4 inches tall, such as a Trichocereus pachanoi or Myrtillocactus geometrizans. If the two cores do not match in size it is very important that you at least cause them to connect at some point.

Now simply use a very sharp and sterile non-serrated knife to cleanly slice the base cactus horizontally, being careful not to saw through the plant. Itþs important that at this point you trim the edges of the base plant at a 45 degree angle all the way around while leaving a flat area equal to, or a little larger, than the diameter of the scion. This is important so that as the scion grows it can basically "roll down" over the edge of the base plant during its active growth. If you donþt cut the edges it is very possible that the scions outward and downward growing pressure will cause it to pop off the base plant.

When you slice the scion plant be sure that it is cut very cleanly and without having to apply much pressure. Such pressure may cause bruising of the seedling or young plant which may in time become infected. Place this cut cacti directly on top of the center core of the base plant, or slightly off center if the cores are of unequal diameter. My own way of ensuring the graft is to use two rubber bands wrapped around the base of the pot of the columnar and over the top of the graft, each rubber band being at right angles to each other. This can at times be very difficult so it is very important that you take your time applying the rubber bands, being very careful that they are loose enough so as not to apply undue pressure on the graft and cause it to burst open at the sides, thereby effectively ruining the young plant.

Once the rubber bands are properly secured the graft should be placed inside a slightly humid environment for a number of days to allow the two to grow together. If the graft is not kept humid often the base plants cut edges will start to rapidly dry and sink, often causing the proper connection of the two plants to fail. My own technique is to place the watered plant within a ziplock bag under lighting for a few days. Depending on the size of the graft I may also simply place a baggie over the top of the plant while spraying a mist of water into the bag to keep up the moisture. After a short length of time the base plants exposed flesh should have callused over and two plants should be securely formed together. They can then be removed from the bag and cared for normally. After 2 to 3 weeks the rubber bands can be removed.

One of the most current grafting techniques I have heard about is to simply place the scion onto the base material as illustrated above and to make a ring of superglue around their connective points. Then one simply needs to hold the plants together with pressure until the glue is dry.

Other tips for successful growing of a graft plant might be in order here. The first is that often new shoots might arise from the base stock of the graft. Often one might want to let them grow a few inches and later cut them off to be used as graft stock. If this is the case then the limb can be cut off as close to the parent plant as possible after reaching 4 to 5 inches and then one can follow the above directions. Since the stock will not yet have roots the rubber bands can be placed around the base of the plant for a few days. Once the graft is secure remove the rubber bands and place the plant upright in a dry environment. After a couple weeks the open cut at the base should have callused over and the plant is ready for planting. If you would like to grow this cut off limb then simply allow it to callous over and then plant an inch or so into the soil. If you donþt want these limbs to zap away the growing power of the scion plant then they should be pinched off as soon as they are noticeable.

Winter Storage:
Many closet cactus growers like myself who may not have a year round greenhouse or live in the appropriate environment will need to find ways to provide for the plants over the winter. With my own cacti I simply slow down watering in September and water only a couple times in October, dependent upon the weather conditions. I also attempt to prevent the rain from soaking them by putting them under cover of roof or tarp. Once the outside conditions begin to consistently fall around 40 degrees at night then I look to bring them indoors for hibernation; the soil being dry by then. Having slowed down their growth outdoors due to the lessening of water they generally do not grow once I bring them in. The medium and large plants are set downstairs and receive little light. Most of them end up in a couple corners of my basement, one of which get a little bit of sun from a window in a southfacing basement staircase. Though some have been winterized in complete darkness they do not appear to be any worse off in the spring than the ones that received minimal light. I also use a small selection for decorative purposes and place them around the house or office, on the window ledges or the end tables. Unless the plants are starting to show moderate dehydration I will not water them at all for the entire winter.

A couple faults of hibernation are root die back and no growth. Since the small roots receive no moisture and are much thinner than the main root sections they will often die. This leads to the slower formation of new growth the following season since energy for growth is being pushed into formation of new roots. There is really not much that can be done about this except to water, but watering, along with insufficient light, will lead to etiolation, the yellowing of the flesh along with uncommonly thin growth. Such growth could kill the aesthetic qualities of the cactus.

Most of my smaller seedlings will be placed under lighting while the newest seeds are sown at the same time. The yearlings receive water as soon as the soil is dried out. If some of the smaller plants in hibernation are showing signs of dehydration I will usually place them under the lights and water till they have regained some of their former glory. Once the small plant has regained its strength I let the soil dry under the lights and then place it back in the dark for continued hibernation.

Growing for Aesthetics:
All my plants are grown for their beauty and so I feel that it is important to maintain the proper conditions that support this. By following the already mentioned hibernation technique one can generally keep a plant for years which maintains a standard diameter and shows only a small pinch in the stock which represents the yearly growth point. Since the columnar cactusþ diameter is dependent on the amount of sun it receives it often happens that a plant grown in the south will have a larger diameter than it would in the north. Usually I will for example get a 4þ columnar that once acclimatized here may only be 3þ in diameter. Since such a sudden change is not very pleasing to look at I will usually let the new growth form for a season until there is at least 4þ of new vertical growth on the 3þ diameter stock. I will them remove this acclimatized section and re-root it. I may then also cut off the section of the base plant that shows tapering, possibly to re-root itself if it is significant enough. I then at least have a nice voucher specimen in the tip to grow completely to form and a short large base of equal diameter that can be either grown to form or from which clippings can be taken for further specimens or trading. It may be advantageous with the base stock to cut the tapering section off at a 45 degree angle so that water does not collect on the tip and lead to rotting.

By following many of the above techniques, and incorporating those which have worked for you in your environment, you should be on your way to maintaining a very nice cactus collection.

    #7940455 - 01/27/08 02:06 PM (16 years, 5 days ago)

Here's what I do.

Shake Schultz Cactus & Succulent Potting Mix through a kitchen sieve. Mix the fine portion with water to saturation and microwave 2x 10 minutes in an unsealed container. Then seal the container and allow it to cool to room temperature. This should sterilize the soil and make sure you don't get any fungal or algal growth. Then, I fill shallow dishes with aquarium gravel, and the last inch with the prepared cactus soil. Excess water drains from the soil as it is being packed into the dish. Then, spread your cactus seeds on the soil and press them down into it, but do not cover. Finally, place the dishes into individual ziplock bags.

I usually get very high germination rates without any fungal growth. At about two weeks, I poke holes into the ziplock bags for air exchange, and gradually increase their number until around two months, when I remove them from the bags. I've found that the longer the seedlings are kept in the high-humidity environment of the bags, the faster they will grow. For me, they tend to slow down when removed, so I don't think I've found the ideal time to keep them inside the bags yet. Watering is usually not necessary while the seedlings are still in the bags.

This technique has worked well for everything I've tried, Ariocarpus, Astrophytum, Lophophora, Trichocereus, Carnegia, and Turbinicarpus.

Hey I had the same problem as you.
I left them to soak and put them on some soil with a bag over them for humidity.
Only a few sprouted and they didnt do well...
Anyway I think the seeds were duds, always buy quality seeds thats the best tip!
Mine were off ebay lol.

I had problems when I tried a few months ago but I think it was to cold. Now the weather has got better I have been getting almost 95% germination. When it's really cold I use an electric heat pad. I've got T. Panchanoi, T. Macroganus, T. Peruvianus (ICARO) and T. Bridgesii. I'm waiting on Loph Williamsii.

I haven't sterilized the soil so I've had to transplant them when the soil got green. I've found once they germinate you can transplant them fairly easy. I'm gonna start sterilizing the soil. but I have a small pie container I fill with cactus compost and put it in a sandwich bag for humidity and put the seeds right on top of the soil and within a week to 7 days they germinate.

At first I had problems because I placed them outside without a shade cloth and they started to burn really quick and turn red so I've been experimenting with tissue paper as a shade cloth. I haven't had any problems yet. I find it easiest to put them under flouros or HID sodium lights. Especially when summer comes cause I'm afraid of baking them in the heat. I might have to move them inside then.

hmm ive actually had an easier time germinating my bridgesii seeds than i have had germinating regular plant seeds

i just keep them in a humidity chamber and occasionally flood the soil and let it drain, ive got at least a 60% germ rate at last count

with cacti seeds its almost impossible to overwater

Re: I'm having the WORST time trying to germ. cacti seeds [Re: Thulsa Doom]

I have had my last lot in for 10days. About 190 seeds, over 50 seedlings so far. I used about 50/50 river sand potting mix. Un-sterilized (the way nature intended). I poked very shallow holes in the soil. Put down a pre base of dry sand and laid seeds then covered in a few mm's of dry sand again. I let the tray absorb plenty of water and left it in a humidity chamber with a 15w fluro grow light. I air it twice a day atleast. They are doing really fucking well, they have almost caught up in size to my first seedlings (26 days old) which i must have fucked up.

Good luck guys!

I had the same problem with the Pancanoi seeds I tried to germinate. I only have 2/25 so far germinate. It's the Peruvianus, Macrogonus, and Bridgesii that have been doing so well for me.

Yep Thats a big mistake allot of us make. i also found that trying to germinate using cactus soil was giving me problems also. Not that they wouldn't germ but without sterilizing the soil it was much more prone to get fungus. I've had to transplant the seedlings to regular SuperSoil and they are doing great. The seeds I originally planted in regular Supersoil haven't had any fungus problems either. I Have about 50 Icaros Peruvian Torch seedlings with a few Panchanoi and Macro's also.

I'm thinking I might leave them under my HPS for the initial 5-6 months while I keep them in the humidity tent. I'm afraid If I move them outside they will bake. at least in summer they will, it gets really hot out here. I can't wait for my Peyote seeds to arrive they should be fun to play with also.

You guys must be doing it inside, I dont really have too bad of fungi problems germinating outdoors. I haven't sterilized a thing for this hobby yet.

Yeh, I've been starting my seedlings inside just because when I tried outside I would burn the seedlings. They would turn red after germination. I haven't had a chance to get any shade cloth yet. So I've been trying different household items out, like Tissue paper and colored saran wrap.
