Ya know... it's the last picture that speaks to me. How much of the "pot" do you keep in water?
It would be quite variable, being considerably cooler in winter than summer. Currently, daytime temperatures are mid 20's celcius on my grow shelf but will be cooler at night.Mobile,
What are your temperatures like? I grow this species but I doubt it will ever flower for me...it's too hot here year round.
I've never used fertilisers on this plant, though I have used an aquatic fertiliser on some of my other Utricularia in the past.Nice one!
Have you ever used your fertilizer on the leaves? I have not intentionally fertilized it (it may have been hit with over spray as I mist the orchids) but perhaps it would inspire some blooms if I were to give it a good misting of orchid bloom ferts?
It allows me to have individual water levels dependant on the species. It also stops the more adventurous Utricularia from growing out of drainage holes and invading the water tray or neighbouring pots.Why undrained?
I collect soup packaging tubs for this purpose but unfortunately some of the supermarkets have started printing directly onto them, rather than applying a label.Maybe I should try that approach...
