looks like a miniature version of your plant

Imagine that you wake up one morning and discover that your collection was stolen overnight… or that an aggressive nematode killed all your cacti or that a small meteor hit your greenhouse 😊. Imagine you are forced to move to a different country and cant take your cacti with you… These all sound lik...

Thank you all for the feedback
I just watered thoroughly after a 5 month dry period and I suddenly got worried that it might be too drastic of a change.
Glad to know that its OK

I heard some people say that after winter you should water gradually.
meaning that you should start with a very mild watering and only after some time give the plants a proper soak.
Do you guys find that to be important/true?
Thanks

I am a plant ecologist and you definitely know a lot more than me

Dave, thanks for the links. Its amazing how many things in plants are governed by auxin. But it still doesn't answer the question of whether this is environmental or genetic or developmental. The fact that different parts of the same plant behave differently could be the result of somatic mutations ...

My son got this cacti in a birthday party. It was tiny and almost dead but it recuperated. My question is about the spiraling. it seems as if only two branches are spiraling. Do you know what creates the spiral? Can it be induced? I assume its silvertii but I might be wrong :) Resized_20240328_17361...

Thank you for all the info, articles and the pictures.
Over the years nurse plants have received much more attention compared to nurse objects.
Rocks have received more attention regarding cacti compared to other plant groups.
If I manage to publish my paper i will share it here as well
Thanks!

Dave
these are great pictures!
I wish that one day I can go on a trip like this...
Thanks!

Hey all I sowed some Lophophora seeds a few months ago (not sure about the species, the guy that gave them to me did not know). They germinated pretty well. Today I noticed some unusual growth in some of them. It seems as though they are offsetting (maybe I am wrong). is that normal for seedlings to...

Hey all I am writing a scientific paper about the role of nurse objects on seedling establishment. Nurse objects are inanimate objects that shield plants from the elements or negative biotic interactions. Cacti are among the group of plants that have been shown to benefit from proximity to nurse pla...

They sure look healthy

and how to kill them?
Thanks

I grow cacti with my son. He is 5 and he is super into it. He drags me to our greenhouse every day to look at the cacti, check who is flowering, look at the seedlings or collects seeds. We grow lots of stuff from seeds and we then trade with local nurseries offering them 2 of our cacti for every one...
