My tuberous droseras

Recommended Posts

Hi all. My tuberous droseras are finally waking up. They are quite late. I made a mistake and kept them after planting on windowsill and they got probably too hot. This is my first year growing them. I am still learning. Today I will show you the tubers. I bought them from Dieter and Lutz. They were photographed before planting on 21.8. 2015. Later I will add pictures of the plants. 7d2dd338258b123f7b83f3cb76da3fbc.jpg

As I promised below some pictures of my plants. Name/date when plant emerged from the soil. I know the plants are strugling - shock from heat after planting and consequent stop in growth, lack of light when they emerged, now days longer but still they manage somehow. Can not wait for better weather to put them outside.

Looking really nice! I presume the white bits are just a topping, and the plants are potted in something more like peat, etc? What did you use for potting, and what's the topping?

Standard mixture for tuberous droseras: 2-3 parts of aquarium silica sand + 1 part of peat. But I am far from expert on tuberous drosera. The topping is about 0.5 cm of pure sand.

Thanks for the info.

 

When you say "pure sand," what kind is it? Doesn't look like the sand I usually see in aquaria shops or builders yards. Looks more like some sort of quartz. Where did you get it?

 

Thanks again.

It is a silica sand. It should be natural not ground - not sharp. I bought it in a local aquarium shop. But not in every shop they have it. I have tried also a sand for pool sand filters which is cheap - 15 kg bags for 13 eur here but I think it is not pure silica. It contains probabky some calcium. But then there is a lot of suppliers of this sand so it is worth checking.

Hi all. I "harvested" for the first time my tubers 3 weeks ago on 11/7:

D. andersoniana had one daughter tuber placed on the very bootom of 10 cm pot in sphagnum. The larger one on the picture:

D. macrantha Rock Outcrop Form had also a daughter tuber, though I was suprised that one of the tubers had already a big stolon. These tubers I planted this week only, the stolons continued to grow, also on the other tuber one formed. Macrantha is one of the earliest species but it is a bit too early.

D. erythorhiza var. imbecilla looked like this: (no tubers, only tuberous roots). I planted them and I can see today couple of plants emerging on the surface. Though now we have a heat wave of tomperatures around 25C;-(

D. aberrans I unpotted carefully after imbecillas and just about the surface I found green stolon/leaves. I put the substrate back. Today the plant is still below the surface.

D.stolonifera

28294308191_a261ed4074_c.jpg

D. gigantea created a replicate tuber even though the plant never made the surface. I had 7 tubers and this is the only survivor

27756356564_d041c28249_c.jpg 

On the other hand D. menziessii had no tuber = lost.

And I lost many tubers which did not grow and which I haven't found: 4 big tubers of D. platypoda, 1 D. zonaria, and 1 D. peltata

 

As you can see not a good first year ... I hope the next season will be better and may be this will help others not to make same mistakes as I did.
