How to grow cacti, cactus, cactuses, and succulents from seed

 

Glottiphyllum depressum, just one of the many succulents growing from seed in my greenhouse

I've been growing succulent plants for about 25 years, but this year I decided to focus on growing them from seed. In this way I could quickly build a collection of rare succulents at low cost, and have spare plents to sell and swap with other growers. I'd grown from seed a few trimes before with mixed success.  One of the first things I noticed was a lack of information online about how to grow succulents from seed.  This page is meant to rectify that by collecting information in one place.  

This page will be updated periodically, so come back later for updates.


One of the first places I found for seed growing info was Mesa Gardens germination tips.

After trying Mesa Garden's mix for my first year I had mixed results.  The germination rates were excellent but then plants seemed to languish.  Part of my problem was that I had to substitute some ingredients in the mix, but mostly my previsou experience with vermiculite was that it holds too much water for succulents.  The ample water holding capacity of vermiculite was good for getting seeds to germinate, but detrimental to keeping the young seedlings alive during those ciritcal first few years.  In fact the plants often died soon after germinating, or were stunted. 



Another resource was Windowsill Cactus.  This page covers earlier efforts to grow succulents, before the development

Hi,
I was wondering if you sell your Metamorphosisenips seeds starting mix.  I don't see it for sale on the site.  Otherwise, can you share the recipe?
