I ordered a pot from Plantedtanks.co.uk to try again now I have soft acidic water. Thought I would try the tropica version as it appears much more compact and is apparently better adapted to aquatic life. Not sure if that was the best idea as it looks half dead compared to the Aquafleur variety I originally tried!
I got three pots instead of the single I ordered so maybe it's deteriorated. The five pots I had last week were thick and lush. This will probably die if submerged so I'll try them emersed and see if they recover.
Do you have any more info on that? It's the first I have heard. I've seen speculation that it requires a mature aquarium but this was put down to it feeding on appropriately sized organisms’ in\around the gravel that obviously takes time to develop.
The rock wool has shrunk quite a bit and the pots are covered in gravel so it does appear to have been kept semi planted before I received it.
At present i don't as I'm sorta busy but I'll point you in the direction of the Barr post I'd read it in asap. I think the mature aquarium thing is more of a speculation than a proper observation, the plant taking nutrients from the water column where it's abundant sort of rules out it being for nourishment from tiny micro-fauna that at best are in a minuscule proportion compared to in the wild.
Bladerwarts are sensitive to ammonia, just like how some plants are sensitive to glutaraldehyde (the active ingredient of excel et al).
They look awful and I would ask for a refund, but I'm pretty sure the yellowing is from lack of light. If you can put them in a tray of rain water (just up to the top of the pot) and cover them with 1/2 a 2 litre coke bottle (so just like a little cold frame to keep the humidity in and better than a big plastic bag) and put them somewhere light, but without direct sunlight (a little back from a window or N facing windowsill) they should perk up fairly quickly, if they are going to recover.
No, I reckon that is at least 2 weeks in the dark.
Nearly all insectivorous plants come from nitrogen poor environments, that is why they have to resort to getting animal protein for their N fix. Generally the problems you get plants from resource poor environments is that they are evolved to be very efficient at "grabbing" cations and anions as they become available. If you then place them in a situation where these nutrients are available you get luxury uptake, which disrupts the organisms metabolism, and often leads to death. In terrestrial plants Protea, Banksia etc. are a great example of this, they come from very phosphorus (P) poor soils and have huge root systems with mycorrhiza etc. if you put them in an environment with normal levels of P, it is rapidly toxic. I'm not sure with Utricularia as it is a funny plant, even for an insectivorous plant, as all their "roots" and "leaves" are probably modified stems.
I dont know if I am allowed to respond to this thread - so on here - I will advise I have been in contact with Alan last night when it was the first I heard of it and immediately offered a full refund.
The plant is far from standard quality and I will find out what happened. The one thing I will say is that when it was packed - I was advised that it looked substandard - so I suggested that they sent enough to make a decent order. In this instance - clearly I should have checked it myself.
I've planted them up as Darrel suggested, I don't think they stand a chance otherwise.
Sorry, didn’t mean any offence etc - I thought that may have been the case as three pots were sent rather than the one I ordered. All other plants were great, very sizable bunches (To the point of being excessively generous!)
An apology and refund was offered after I contacted Tony.
