(gymnocalcium damsii) to much sun?

[Bert&Ernie]

ok this is one i bought from a little old lady who was very sweet i cant remember if it was in full sun or not when i bought it but i put it into full sun anyways my question is is it getting to much sun or what?

also here is one of the pups that i grafted onto an opuntia vestita wich i think might be rotting or somthing?

sorry about the poor photos they are from my phone

Yeah a bit too much sun & slightly dehydrated, they tend to do well in a greenhouse or shaded veranda with part sun or morning sun

is the side thats browning the side that cops afternoon sun ?

the graft may not have taken or its getting too much light too early

Looks like some burn has already occurred.

[mac]

the graft will do ok if it has taken, just put it in part shade with the other one & they should recover

Ive noticed with the various Gymnocalyciums that the ones with finer weaker spines prefer more shade than the ones with thick strong spines...interesting graft!

yep, I've burnt gymnos and they're supposed to like it more shadey compared to sun lovers

[Bert&Ernie]

thanks for the great info everyone

[Bert&Ernie]

here's an update on this little beauty after I moved her onto my front porch she has no signs of sun burn at all

I grow all Gymnos under shade cloth after doing some reading the bulk of the more common to cultivar species grow in grass lands through filtered light, and in my experience can handle frightening amounts of water during summer. The first G mihanovichii was found a metre under water during flooding. It was taken back to Europe and survived.

either that or shade grown plants grow spindly spines and sun grown plants develop sturdy strong ones.

jwerta, you may want to cut off the other branch of the graft stock, let the plant concentrate on one point.

Heres a pic of some mature damsii plants in flower these guys, as it gets hotter get the reddish burnt look, the seedlings almost have a variegated look if they get too much sun. I have a cultivar that has black were you normally see red, its pretty cool only just got it will try and take a pic later if your interested. thats a 25cm pot I think, big plants.

yea i should have but unfortunately the graft failed and then a few weeks later the stock got some really bad rot and died
