Hello,
my D. esterhuyseniae died to the roots. If i remember well, this species usually does not have any summer dormancy, but i think, that moving to the greenhouse (and thus sudden change of conditions) led to this. Now i am not sure, whether to keep the soil dry (like D. cistiflora) or wet (like for D. aliciae, it also makes this from time to time) or just moist - not standing in the water, but not completely dry? I would guess, that the third optin is probably the best, but i would welcome any other experience, since this species is quite hard to get and i really like it.
Thanks in advance
Adam

Hello Adam,i see the same whit mine ,i try everything to safe this but i never seen a new plant again,i supoose it s to hot in a greenhousse for keep alive plants like this.
Some other South American do the same ,some came back others not,she also not love the heat.But i think not let dry out the ground ,hold it moisture not wet ,meaby you have lucky and your plant came back from the roots  :thumbsup:
It s one of the reassons it s hard to find ,like all the hard to find species she are very difficult for hold alive on long term.
Cheers Will

Thanks Will, i agree. I am thinking about digging up some roots to make root cuttings. I have remembered a very similar situation in D. cuneifolia. It also sometimes dies and never regrow again, while other plants regrow with no problems.

It s the best way to multiply cuneifolia,you must take the thick roots and cut them in pieces from 2 cm, put above on the ground and covered this whit a 0,5 cm ground and set in water,all this pieces become new plants whitout any problem ,i do this everytime i need more cuneifolia.
This can be done whit all the drosera plants whit thick roots,i have done this whit  slackii,alicae,cuneifolia,curviscapa,madagascariensis,ascendens,gramogolensis, and hamiltonii.
Esterhuiseniae ,i not try but when it have thick roots it must be word to trying.I try ones whit a ramentacea because his thick roots but this not working for me,so it s not work whit all of them
Cheers Will

I tried it with ramentacea as well - with no success as well. Maybe it needs something special or it simply does not work with it. I am going to cut the esterhuyseniae... and i hope i wont get an empty pot :-)

Once more i am here... while repotting and cutting the roots of this dead sundew, i have noticed a problem with the roots which i have already observed before in other sundews (D. regia, D. graomogolensis...). I keep the plants in tall plastic square pots, which are great for keeping a lot of species on a small area. But once the roots grow long enough and touch the inner side of the wall of the pot, they often rot. Especially during hot weather, they easily get literally boiled (especially when the sun shines on the black pots on the edge of the trays).
It sounds logical to me now, that this could cause the problem - black pots + hot weather = overheating of the soil => rotting roots. Moreover, the plastic pots are impervious to air, which, i think, makes it all worse.
I am thinking about repotting the most sensitive species into clay pots (considering the discussion here on the FAQ section: Keeping pots cool), i hope it will help.

Therefore i allways use round pot s,red or black ones it s make no difference,the air go better arround the pots and keep it cooler,i have allmost all my squire pots done to the container,another mistake is that squire pots lesser place need ,you can set more round pots on the same spot,try it and you see.
This is the biggest problem in a greenhousse to keep your ground cool when it s above 30° outside,i use very big trys (90 liter)for plants that are sensitive to this ,she standing on the floor,it s go match better in this ,the only you must see is not to give to match water, i must give only ones in a month in summer,ground stay wet for a match longer time.
Plants go in rest when temp go above 25° ,you see this in your garden as well,you must not cut your gazon when it s hot,the problem is when she go in rest she need no water anymore ,in nature she standing in cool water and stay in grow ,in a greenhousse the water in the try can be very warm ,the plants rot because she are resting and have to match water .So the best is give no water at all when it s hot but i don t know whit droseras ,i not try yet,meaby she are drying out above ground level?
Cheers Will
