Drosera dielsiana. This plant is 3cm across. |
Drosera dielsiana is found from eastern Transvaal to northern
Natal of South Africa northward into southern tropical Africa where it
is found in mountainous regions. The small plant makes an excellent addition
to any terrarium.
Drosera dielsiana isn't very picky about soil. It grows well in
pure sphagnum moss as well as the standard 1:1 peat:sand "CP mix".
It will tend to be redder in peat and under brighter light. It may live longer in pure long-fibered sphagnum.
Sow seeds of Drosera dielsiana on the surface of your medium of
choice. Finely chopped live sphagnum moss over long fibered sphagnum moss
or CP mix works very well but the moss can overgrow the plants. Finely
chopped dead sphagnum or sand over CP mix also work well.
What you do next depends on what works best for you. Everyone has their
own preferred routine. I put pots with seeds in plastic zip-lock bags
under but not too close to fluorescent lights. You could also use an aquarium in a greenhouse. The purpose of the plastic bag is to maintain very high humidity and to keep out fungus gnats. Fungus gnat larvae will eat the seedlings. A temperature between 20°C
to 25°C (70°F to 80°F) works best. The seeds should germinate in a few weeks. When the new plants have a few true leaves, remove
the pots from the plastic bags and put them in a bright terrarium or greenhouse. The seedlings may be a little slow growing at first. Have patience.
Once the plants are large enough you can try feeding them small insects
or get some dried blood worms at a pet shop. The dried blood worms can
be dipped in water and placed on the dewy leaves--don't feed a plant that
isn't dewy. If the food gets moldy, use less next time. A dab of 70% isopropanol
(rubbing alcohol) from a small paint brush will kill the fungus.
Drosera dielsiana tends to live a year or two. It can easily be
propagated from root and leaf cuttings. When it blooms, save the seeds
to grow more. If you have lots of seed, send the extra in to the Seed
Bank.
