Re: Seed raising compost

If you use purely mineral mix, assuming no nutrients or trace elements are derived from the mix itself which is unlikely, you need a balanced fertiliser that provides all the trace elements normally obtained from the organic part of potting soils, one similar to those suitable for hydroponics. https...

Re: lophophora companion / nurse plants

You also may find some information here:- https://sacredcacti.com/blog/tag/nurse-plants/ https://www.sciencedirect.com/topics/earth-and-planetary-sciences/nurse-plant However you may not have access to the same nurse plants as in habitat and many are found not just under shrubs but among grasses, th...

Re: Pyrrhocactus

I have virtually not been on the Forum for the last 4-5 years but when I put a link in to a new Pyrrhocactus on our branch email circle one of our branch members reminded me of this post. It therefore seems a good place to put in the new Pyrrhocactus for comparison purposes rather than in a disconne...

Re: Can anyone explain this columnar lophophora?

Could they be clones from offsets from an original plant since both look remarkably similar in size and character? All plants are individuals if grown from seed, but propagating from offsets will produce genetically identical plants. However only a DNA test would prove this. Those who grow Lophophor...

Re: CactusWorld (Dec 2023) Copiapoa

Hi Benjy I "Googled" Copiapoa using one of the localities and found 3-4 year old seedlings under Copiapoa sp or Copiapoa longistaminea aff (= affinity) were being sold by a Bulgarian nursery at €10 each, so obviously have been available in the EU for some time though unnamed. Therefore as ...

Re: CactusWorld (Dec 2023) Copiapoa

I forwarded this discussion to Roger Ferryman and this was his reply:- "I struggle a bit with Copiapoa, there are many overlaps and it’s easy to pick differences yet they are not always consistent. Regarding saxifraga it does not grow where Benjy suggests. The place is not well visited because ...

New Mexico Cactus Research

Hi All If you are as old as me collecting from the 1960's you may have obtained seed from New Mexico Cactus Research = Horst Kuenzler. You may still find material grown from their seed with HK numbers. They suddenly seemed to disappear and I found this article about it. At the end there are links to...

Re: Cacti Without Soil

If you are growing hydroponically, semi-hydroponically or in a purely mineral compost you need a fertiliser that supplies all trace elements needed. Some general garden fertilisers rely on the plants extracting some nutrients or trace elements from the organic part of the soil. Therefore check the f...

Re: Cacti Without Soil

Cacti like most plants can be grown hydroponically in one form or another, the nutrients supplied in solution rather than from organic matter in the soil.. https://gardeningwithallie.com/can-cactus-grow-hydroponically/#:~:text=Yes%2C%20cacti%20can%20be%20grown%20hydroponically.%20Cactus%20roots,it%2...
