I open this post to share my sowings.
I'm kinda bad at growing cacti and succulents from seeds. Hopefully this year I will be more successful.

Wow they are so beautiful!

I also grafted this Aztekium ritteri on August when the seedling was 2 mm large.

This summer I practiced for the first time some grafts with seedlings produced by my Lophophora.
All the seedlings were grafted ad 2 months old in July. I found grafting on Pereskiopsis really easy getting a 100% success

Ty for the help

Yes I have a D. elephantidens/elephantipes and it should be a winter grower.
So should I water(if it keeps showing new growth) even in december or january when the temperatures will be even lower?
I never had winter growers before and I'm really confused.

Some months ago i bought a little Dioscorea.I have no experience in its cultivation and I don't know how to treat it in winter. Now in Rome the temperature range from 18 and 7 C.(I watered two weeks ago when the caudex was soft). Does it keep growing even when the temperatures are kinda low? Should ...

I wouldn't order from Koehres. Usually the quality and the germination percentages are very bad.

Could it be the damage from a spider mite attack?

I think you should cut with a sterilized knife the sick parts.
To prevent this infections during the vegetative period you should place it outside.

Thanks for the help! Dimethoate is a systemic that is absorbed through foliage.

I think that they are collembolas (fairly harmless arthropods).
Do they jump when you disturb them?
They often live in the bottom of pots and in humid places.

Can you help me identify this pest that i found on some of my pereskiopsis? They are really small(<5mm). The sick pereskiopsis had on the top side of some leaves a white coat and the bottom sides were consumed and presented little black round things (eggs?). I sprayed them with dimethoate. photo_201...
