All the Drosera tomentosa var. glabrata plants on the green wall of my terrarium now show their best color, as a reaction to the new and fairly powerful LED spotlight (see the March 2020 update here). They stand out nicely against the green and yellow tones of the surrounding moss.
Two of my largest specimens are about to flower. The rosettes are 3 cm wide and grow well among the various mosses and other little plants that have colonized the tree fern panel of my terrarium. A very pleasing sight.
I bring some nutrients to the whole panel once a month, with a very diluted orchid fertilizer. As you can see, the sundews do get their own prey. Really cool if you ask me. Oh and the gnats don’t mold on the leaves like they did on Drosera spiralis.
The plants that germinated on the tree fern are now almost fully grown. Those that were in the sphagnum moss have been transferred alongside their siblings, with the help of a toothpick.
While the wall is not as densely covered as I imagined it, it’s still satisfying to see what looks like a successful expriment of growing Drosera on such an exotic medium. Yet I suspect that the plants will eventually lack nutrients, so I may try and give them foliar feeding at some point. This should also make them grow larger, and perhaps enable flowering.
When I started thinking about my new terrarium, I envisioned a wall covered with glistening sundews. Starting from seeds is the way to go, and it can be very rewarding, so I bought a packet of tropical Drosera seeds from a member of the CPUK forum. Here comes Drosera tomentosa var. glabrata from Serra do Caraça, a mountain range located in southeastern Brazil.
Upon reception, I sowed the seeds directly onto the tree fern panel and made sure to keep it moist enough. Because I had no idea how well they would germinate, I also sowed a few on living sphagnum moss. The plantlets would then be transferred to the tree fern panel. Well, those I could find.
A month later, they are coming to life…
