i already was a rot on one of my cacti and i cut almost half if him...

now other cactus start be very soft, and get a sick green color. also he start get Wrinkles...

i live in very hot area, the temp is around 35C on the shade, and the lophs get full sun

i water my plants every week, and i think is too much...

Looks like sunburn.  I'd be careful, the skin never really recovers from that and it will be prone to rot in those wrinkled places for a long time.  Lost my favorite plant that way.  In the future, keep your lophs in filtered/dappled sunlight.  They like strong, bright ambient light but they need it to be mediated through a shadecloth, tree leaves or some other plant.  Direct summer sunshine will shrivel them up and sometimes kill them.

Sorry - I TOTALLY disagree with the above.  Lophophora are native to the Mexican desert, and live in a totally sunny climate.  My own Lophophora williamsii are fully exposed to the strong Spanish sun and they love it.  Never heard of one getting sunburn, in the 15 years I have been growing them here. 
The only way this could happen would be if a plant were moved from a shaded exposure to a sunny exposure without letting it acclimatise gradually.  When I buy any plant from Northern Europe I let it gradually acclimatise to the Spanish sun over a month or so.

it's sunburn.
well, more accurately, they are cooked.

i have have had the sun burn the living shit out of my entire collection of seed grown lophs
and i live in the netherlands.
my mistake was to put them in mini greenhouses to keep the magpies away.

lophs can take all the sunshine you can throw at it, but they do have a maximum temperature
and will be cooked if you go over it. even in mexico lophs, like any plant, will favour some spots
over other spots.

put them in a spot where they are not in direct sunlight at least at the hottest time of the day
and maybe a spot with more moving air if you have one.

also stop watering them daily.
if you think they need water, gently squeese them. if they feel soft and squish they need water.
if they feel firm, leave them alone.

here in holland i water my lophs about 3 times a year.
none in the winter, i let them shrivel up all the way.
in spring they get a liberal watering, maybe twice, until they have regained their
volume and shape.
then once more a big sploosh in the middle of summer and one more time in the beginning of fall.

I don't grow lophs anymore,but when I did,I always grew mine in full Florida sun,and never had any sunburn,or problems.

No offense,but I don't understand why most of you guys that grow lophs tell people to keep them in shade,or dapled sunlight,or to only water them a couple times a year.I think it's preposterous!

In their natural habitat,they can be found right out in open sunny areas that never get shade,and guys,come on,it rains more than two or three times a year in the desert!

I know for a fact the Texas region where they grow gets ample rain throughout the year.

I do have one Lophophora alberto-vojtechii,and he gets misted nearly every day,and gets a good watering twice a week,and he is growing nice and healthy,as to be expected.

All my other lophs,when I grew them,also grew in pristine shape,and flowered all summer long,in full Florida sun,and watering two even three times a week during the hottest parts of the summer.
The key,when growing them in full sun,is to water them more frequently,it's just that simple:wink:

You guys in hot climates don't realize that it is impossible for people with colder climates to have their plants acclimate and harden off.  They're basically always stuck halfway between dormancy and full growth, so when we get our one week or so of 100 degree weather a year the plants get shocked and if they're in a place where they get too direct of sun, they will sunburn/cook. 

If you're lucky enough to live in a place where you can put your loph in full sun in the ground then sure, once it acclimates it will be tough as nails and turn pure glaucus blue and tolerate temps up to 120 degrees F.  However, for people whose plants are used to 80 degree days and 60 degree nights in SUMMER, a swing up to 100 will fuck them over royally.  My night temps are always too low and the swings during summer too variable, I've actually stopped keeping lophs outside in the summer unless the forecast is perfect and even then, they get shade or dappled sun.

Well k.b.g, it's not like that.

First, you can't recreate in pots the "natural" conditions in which Lophophora (or any other cactus, for that matter) grow in the wild. One VERY important difference is soil temperature, extremely hard to keep down in pots when fully exposed to the sun. When you think of the large, fleshy roots of Lophophora and think of a hot, moist substrate pot, the conditions become more akin to a stew than a "natural" setup.

Second, where did you see Lophophoras growing "... right out in open sunny areas that never get shade..."? And before you talk about mudflats, think again on how the plants pull themselves into holes there, being shaded by the hole they dug for themselves and covered in dust.

It's ok to give advice based on your own experience - that's what we're here for. But knocking other people's advice calls for a bit more than "I did this and it work, you must be wrong".

And, FWIW, I grow my Lophophora shaded, water them when they need it (that can be weekly or monthly, there's no fixed schedule) and they grow all right and flower as well. Should I say your growing advice is preposterous? :wink:

(no offense intended, nor taken, of course)

like i said i burnt mine by putting them in a mini greenhouse.
it made them way hotter then they normally get out here and it did severe damage
in only a few hours.

aside from what has been said i also wonder if humidity plays a role in cacti's temperature tolerances.

in any case the pictures clearly show heat damage.
the only way to fix that is to move them to a cooler spot.

I can only speak from my fairly extensive experience - I bought my first cactus in 1957, and have been growing Lophophora and other genera of cacti for 15 years in terracotta pots, on tables in the open air in summer, in Spain - where summers are HOT and dry.
I water them well once a week in summer. 
I have NEVER, repeat NEVER - experienced ANY KIND of sunburn.  My plants love the climate here and grow well, Lophophora flowering all year round. 
In the warm, wet winters they go in cold frames to keep them dry, but still get as much light as possible.

I echo the sentiments of others. Sunburn..and Also looks like shriveling from (Underwatering).  I water my cacti in the greenhouse almost daily with temps in the mid to upper 30's if, with a gentle touch the cacti is (sqishey) it might be rot.. but your top image looks more like mine, after thay have had a period of winter rest and water loss.

With overwatering you plant would more than likely be (bursting) cracking, and throwing out all kinds of pups. or else just giving up the fight and turn to puddle of mush.

As others have said. Its possible to (cook) you cacti in direct and full sun. When I give a cacti as a gift to someone, I try and politely remind them, how the little guys start their lives, (Under bushes and shade trees in the desert biome. Otherwise if they are in the Open-desert, they usually grow in the shade of a large rock, or bigger cacti.

If I were to offer advice, I would say..try reducing the amount of direct sunlight they get each day.

good luck.

i believe i experienced similar shrivelling with my sunburn lophs at the time.
if i remember correctly though those parts recovered. only the discoloured parts eventually dried up and became hard.

i should take pics, one of them is a great example of how little of a cactus can be left, but still alive.

i forgot to mention that the main reason for my sporadic watering is the low light conditions
we get in holland. we have a lot of cloud cover and sunlight here is 8 and 16 to 16 and 8.
if i water them more they grow lopsided and i water as little as i do mostly to retain their original shape.

like i said before: the best way to water them is to feel their rigidity. if they are well watered they should be firm.
if they are not they can use a splash, as long as you are in the growing season of course.
it is normal for the lophs to shrivel up like a raisin during their dormancy.

Both times I've seen shriveling like that it was heat/sun damage.  I'm above the the 45th parallel, I think that sunburn is actually more common the further north you are as the light is more inconsistent and plants don't get as accustomed to full sun.  even if they're acclimated.  Wide swings in temp de-acclimate them and they get all fucked up.  Cool nights then really hot days are particularly bad combo. :shrug:

Maybe I'm missing something but it seems like a number of people are talking as though the OP is in a cool climate, while his profile says he's in Israel. I have no experience growing in such a hot climate (35+ C is very rare in the summer here) but I have seen the "cooking" phenomenon before (transported many peyote plants stupidly in sealed ziploc bags in the summer and nearly all got that distinctive wrinkling and mushy texture and died.) When I've seen sunburn it tends to be either that I didn't introduce the plants to sunlight gradually enough, or reflections off shiny surfaces. I believe in the wild they typically live in shaded locations under shrubs and so on, but mine seem to do fine in full sunlight as long as they're exposed to it carefully.

Whether overwatering in a Mediterranean climate during extreme heat might contribute to "cooking" I can't say as it doesn't get quite that hot here and I water fairly infrequently, but it seems like a reasonable theory and erring on the side of underwatering generally is pretty safe. The first plant looks to me like it's a bit "cooked" and may or may not be sunburned, and the second plant that was a new acquisition (and perhaps re-introduced to sun too fast?) has some definite but not extreme sunburn. With the one that isn't a new acquisition, a sudden sunburn seems like a somewhat unlikely scenario if it was already in similar conditions for some time.

No, people from cool climates are saying that sunburn/cooked plants are a very real thing and because it doesn't seem to happen as much in warm climates where the plants get acclimated to high heat people from dryer climes are claiming peyote don't get sunburn.  Everybody that has had their plants cooked agree that this is heat damage, the rest are claiming that heat damage doesn't exist.

Take this for example:

Israel and Spain have very similar climate conditions, no?


In any case though, IMO the real question is why now. If the first plant has been outside for a while, why did this happen now and not before? Is it hotter now in Israel than it was in July or August? Has something else changed that he didn't mention?

i would argue that it differs from spot to spot, even in one's own garden.
and your questions are academic.
these cacti suffered heat damage, and there is only one thing you can do about it.

Those questions aren't just academic, because they are potentially relevant to avoiding a repeat of a similar situation in the future.
