Genlisea die-back


Rob-Rah

Recommended Posts

About a month ago I receieved my first 4 Genliseas, just a leaf or two each and a couple of little roots. All but one died back, and now two have started to make new leaves above the substrate. There's still no sign from the other two.

How long do you think I should be patient for? Can they take a while to get established and re-shoot from the roots, or do you think that if they haven't done anything after this long that they're probably goners?

Fwiw, they're potted in uncompacted peat/sand with the water level ardound the surface of the soil, and temps are 10-30C in semi shade.

Hi Rob,

it is sad to hear that 3 of your 4 plants died back at the beginning and two of them still show no sign of growing. :(

Your growing conditions sound ok for me. However, I keep the water level for my Genlisea much lower. This seems to be all right for at least Ge. lobata, Ge. violacea and the hybride of both. They are continously flowering under such conditions which I interpret as a good sign, allthough I might be wrong with that.

I can not say much about other species, as I do not grow them long enough.

Do you grow your plants in a greenhouse or terrarium? Do they get air ventilation?

Regards,

Dieter

They're in a large heated tank (4' x 3' x 2.5') within a greenhouse. It's not particuarly airtight, and is not stuffy, but the humidity is very high.

I was pessimistic about all four plants a few weeks ago, but was pleasantly surprised when I looked at them a couple of days ago to see that two of them now seem to be OK. Maybe it's just a matter of more patience for the other two?
