I have a very weird fuchsia problem. My fuchsias look healthy but the flowers are drying up and falling off before blooming, why?
I bought 2 fuchsia starters/cuttings about 8 weeks ago and they came in 10cm pots, which I am still using now. I have not repotted the plants, but they are growing very much now (about 10 inches tall). Both have lots of buds on them and it looks like they would bloom quite soon. I keep them at my windowsill indoors (I do not have a garden or a balcony) where there is morning sun and then shade the rest of the day.
However, a few closed buds have had light brown, dried up spots on the surface and, eventually, they dry up even more and then fall off. A few on the other hand, have small lesions or holes that looks like something has bitten the buds, but when I took down one bud and opened it up, there were no insects or anything weird inside. You can see on the picture I posted. However, these lesions are also causing the flower to dry up before blooming. Those buds that do not have any lesions on them are half open and will soon go into full bloom. I also feed both plants with an all-purpose liquid plant food (Miracle gro) once every 2 weeks and water them every few days (when soil is dry), keep them in a shaded area and mist the leaves once a day.
The plants are perfectly healthy with nice foliage and there were a few mites that I quickly pinched off and a few fruit flies flying around. I tried to kill as many fruit flies as possible whenever I see them. But, do you think this could be the problem? Do fruit flies eat the exterior of closed buds?
Another thing I have noticed today was that the plants were dry in the soil and so the leaves were slightly droopy, so I watered them a little (this was around 3pm). After 2 hours, the leaves perked up again but all the flower buds started having light brown dried spots on them. These buds were completely fine before I watered the plant. Could that be due to overwatering? Or does the soil not have enough drainage?
Thank you very much!!
