congratulations Chris on getting one to rebloom and getting so many to put out spikes for you!
I used to work at Lowe's and was always bringing plants home to save....my experience is that not all
plants can be rescued. I used to try and get a peek at the roots before actually buying a plant as often times
they were all rotted and beyond saving. I had the best luck bringing them back by keeping them in the house
with just bright light...if you have grown and had success with African Violets..that sort of light , where you could
sit and read. Once I got my greenhouse , it was much more difficult for me. I don't know if it was just too much humidity,
or light or what...You may also have some problems with any buds or spikes if you are using propane...some plants
are very sensitive to gases. I had mine in a bark, charcoal mix and only watered twice a month...
Also, have you got good air movement in your greenhouse?
fingers crossed for you!
