Help with Trop-Hibiscus
My brother bought me a huge hibiscus last summer. I brought it indoors and it almost immediately defoliated. All the leaves fell off whereas it was looking really good in a pot outdoors.
I thought perhaps it was just a thing and it did put out a lot of new leaves. These leaves started drooping badly and getting super dark black spots on the leaves and they all fell off.
It started to die back from the tips. I cut those off below the problem and re potted and discovered it was three plants in the pot. I took off all the dirt and set them in a bucket with captan water (only anti-fungal I have) overnight.
I separated into three smaller pots (to try different things) and new dirt. The few leaves left perked up but, still it continues to die back in the wood.
I have about 5 others and they don't appear to have this problem and still look really good.
Any help experts?
