Growing Drosera Seeds

by sanguinearocks101 » Tue Jan 14, 2020 11:40 pm

Hello, I have just requested some Drosera Capensis mixed seeds from the seed bank (Thanks Shadowtski I couldn't ask for more help than you've given me) and I think I have it down how to grow them but I want to make sure. What I know now is that you disperse the seeds evenly on the media, keep the media moist, put it in a bag for high humidity, and give it sun for half the day. I heard that you have to keep it cold for a period while they are germinating, can anybody confirm if this is true for me please? Please also tell me if there is anything else I need to do.

Thanks,

You've got most of it down. My process goes something like the following:

    1)Mix and hydrate soil — I use 1:1 peat perlite
    2) Fill growing container to just below the top, lightly packing the soil down
    3)Evenly sprinkle seeds over the surface of the soil
    4)Lightly mist the surface to help settle seeds and place in growing environment
I grow most of my plants in an enclosed space in a tray with T8 lighting which keeps humidity at 65-70% and temperature around 80°F when the lights are on (12 hour photoperiod). That being said I don't bother to enclose my seeds with a bag, whether or not you do so yourself will depend upon your growing environment.

As for keeping the seeds cold, some do have to be cold stratified before being seeded. However D. capensis does not need this and will appreciate it if you can keep them on the warmer side. I don't know where you live but I assume it is winter there which means you will want to place your plants on a sunny windowsill in a bag (make sure if you do this that the seeds don't get cooked) or under growlights if you have them.

This is certainly not the only path to success, merely my way of doing things. Capensis is very easy to grow and should be a good place to get your feet wet in the world of growing from seed, enjoy the process!

That's pretty much how I sprout my dew seeds, except I keep them under intense light. They sprout fine for me either way, they just grow faster under brighter light. While temperate dew seeds do need a cold period to simulate winter, capensis, a tropical plant from South Africa, does not. Capensis is a really easy plant to sprout and reaches maturity very quickly. Good luck!

Do you use long-fiber sphagnum moss for drosera seeds?

I use 1:1 peat perlite myself, I believe LFSM is a popular choice for Drosera though.

I'm about to plant Drosera from seeds for the first time and am doing some research on it. This post helped me alot on where to get started.

Just some musings based on my experience, YMMV:

-LFS is fine for germination, but it can be a pain to flatten it so that the seeds have ample contact with the rest of the pot. This is important when the seedlings need to start sending down deeper roots. Some people suggest blending or chopping it up.
-Wash your media, wash, and wash again. There is nothing more annoying than running into algae or mold with seedlings. I'm considering baking or microwaving the media next time I do a round of seeds to see if that helps.
-Related, but sometimes bagging can create more problems than it is worth. It is nice for water conservation (you never want your seed pots to dry out), but with little air flow it can promote algae/mold and also becomes an unnecessary issue when you have to transition your seedlings to your ambient conditions. Unless your growing space is super low in humidity, I wouldn't worry about it with most sundew seeds.

Capensis are a great one to start off with though. Best of luck!
