Gone to Seed
by Stephen Cooley

Part Two: What Do I Do Now?

After you have decided that you want to start some succulents from seed, the next step is, of course, to get some seed. Seeds of a great number of succulents are generally not hard to obtain and there are many sources. These include buying seeds from a supplier, begging from your fellow club members, and collecting them right off the plant.

If you choose to collect the seeds from the plants there are a few things to consider. You will want to be sure that the seed is mature and will germinate once you plant it. If you are not collecting from your own plants, getting permission before you do would be a good idea. If you are collecting from the wild it might be prudent to know wether it is even legal to do so. I plan on writing more about this in the future.

Another good source of seed is your fellow hobbyists. Many who have large collections often get fruits on their plants, many times without any help. People who grow plants from seed may have extra. Ask around and you’ll probably wind up with some.

Perhaps the best way to get your seed is to buy it from a supplier. There are many to choose from and the best place to go is to the internet at: www.cactus-mall.com. Here you will find a listing of links to seed sources. However, there are two suppliers that I would like to mention here because they are good places to start. For those of you that are members of the CSSA, the Seed Depot is a wonderful starting point. Here you will find a wide variety of seeds that are donated by members. They are just 50 cents for each packet – which is a good (and sometimes a real bargain) price. You must be a member to order from the list, however. I have ordered many seeds from the CSSA Seed Depot and have had very good luck germinating them. The year’s list is printed in the January issue of the CSSA newsletter, "To The Point," with supplements printed with subsequent issues. Directions for ordering from the Seed Depot are included with each newsletter.

The other supplier I would like to mention is Mesa Garden. Mesa Garden is familiar to almost anyone who grows from seed, and for good reason. They have the best selection on the planet. In fact, the choices are so great that the uninitiated may find it somewhat daunting just to look through the catalog. This is the place to look if you’re trying to find a particular species or even a species from a particular locale. Looking at the 2003 catalog I count 26 entries for Conophytum pellucidum, varying mostly in where they were collected. Mesa Garden doesn’t lump their seed together, but lets you choose which one you want (would you like the olive-green bodied C. pellucidum collected 15 miles west of Platbakkies, or the contractile form from 20 miles south of Kamieskroon?). The prices are good and the germination is high. I have spent far too much money buying seeds from them and I’m not likely to stop anytime soon. You can find them at www.mesagarden.com, or write to: Mesa Garden, PO Box 72, Belen, NM 87002.

Now that you’re getting some seed, you need to plant it. Before you plant it, let’s talk about what the seed needs to germinate. Basically, seeds need moisture, warmth, and air to germinate. For many succulents there is another requirement, light. Most Cacti and Mesembs require that the seed be in the light in order to have good germination while some others, like Aloe, Agave, and Pachypodium do not. Another factor you need to consider in planting your seed is disease. There are a number of diseases (usually fungal) that can attack your seed and seedlings. Cleanliness usually does the trick though there are pesticides that will help as well.

Now a word or two about soil. There are as many soil recipes as there are growers so I’m not going to get too involved here. The important part about your potting soil id that it drains well. This usually means the addition of perlite, coarse sand, or pumice to your mix. Your mix can either be organic (peat moss, coir, leaf mold, etc) or mineral (garden loam, sand). Personally, I have had my best results using a strictly mineral soil, adding no organic components. An important part here is that your soil be sterile. Store bought mixes as well as perlite tend to be sterile right out of the bag. Other ingredients will need to be sterilized. To do this, place your wet mix in an oven roasting bag, seal it, and cook it in a low oven (160-200F) until the inside temperature is to about 180F. I have also had good results by placing a clear plastic bag of wet soil in the hot sun and turning it everyday for about four days.

Now you’re almost ready to start planting your seeds. First, let’s clean the pots. Any pot will do as long as it is clean. By clean I mean that it has been washed out to remove any clinging matter and then sprayed with a 10% bleach solution. The pots then should be put in a plastic bag, sealed, and let sit overnight. Cleaning your pots and soil means you probabl;y won’t need any other disease controls.

Okay, let’s plant. Take a pot, fill it with moistened soil, then settle the soil by gently picking the pot up about an inch and letting it fall back down. If your planting a species that does not require light, then leave enough room so that you can cover the seed with about one quarter inch of soil. Now, sprinkle your seed on the soil, covering it if necessary (Many growers will now also sprinkle the light requiring species with a very small amount of sand – I wait until after germination). Remember, almost all Cacti and Mesembs require light to germinate. Now, water the seeds by placing the pot in a tray of water. I also tend to spray water on the surface seeds just to make sure they’re in contact with the soil. When the soil is wet, remove the pot from the tray and allow it to drain a bit. At this point, the pot needs to be covered to insure that the moisture is retained. This is easily done by placing the pot in a zip-top clear plastic bag. Any other way of covering the top of the pot should work as long as the light can get through. Place the covered pot in a warm bright area, not in full sun. This could be a window sill or fluorescent lights (which I use and they work very well). For most species, a temperature of 75F is good. Some like it hotter and many of the Mesembs like it cooler, but household temperatures are usually okay. Your new babies should arrive in about 7 days (or as little as 1 day or as much as 1 year, depending on the species and freshness of the seed).
