Today I got to go to the Austin Cactus and Succulent Society plant show and sale! First of all, I must say that the Zilker Botanical Gardens is very lush and beautiful right now (especially after the bit of rain we got mid-morning). It was quite wonderful to stroll the winding paths with my husband this damp Sunday afternoon.
Here is what I learned:
Most succulent varieties are drought tolerant and cold-hardy if planted outdoors (look for varieties that come from climates similar to Texas).
Cacti and succulents like to be fertilized regularly in spring. Eric Pedley from East Austin Succulents says he uses 20-20-20 fertilizer or fish emulsion. Seaweed works great too!
Top dress your potted succulents with pebbles or hardwood mulch.
In my latest experiments I've concluded that it is best to leave your succulent in its pot when using in a "dry" terrarium. Succulents need a combination of soil, sand and perlite to thrive in their environment. They tend to get sad over time if planted in sand alone. It also makes it easier to re-pot your succulent as it grows. You can add it right back into the terrarium once you're done! Look for a post on assembling a terrarium kit to illustrate this better soon. It is also a good idea to thin any "pups" and pot those separately for future terrariums.
If you find yourself drawn to the strange and awesome world of succulent plants, be sure to check out The Austin Cactus and Succulent Society website and their upcoming events. Their next scheduled sale will be Labor Day weekend.
Here is a recipe I've found for making your own succulent potting soil:
2 parts coarse sand
2 parts good-quality potting soil (I like Vortex Potting Mix from The Natural Gardener)
1 part perlite, vermiculite or pebbles (perlite and vermiculite are not considered organic as they do not break down organically, but I'm OK with that)
