Dwarf Hibiscus

Question

We purchase 6 ‘dwarf’ hibiscus from Loews. Planted them 2 years ago on the east side of the house – lots of sun for 1/2 day. 2 are enormous with dark green leaves and vigorous flowers – but the rest appear enemic with bland looking leaves and few blooms. Sprayed with fungus stuff last spring – no change in result. Is this because not enough sun? Too little fertilization?

Answer 1

It could, definitely, be lack of sun! It could be lack of fertilization, too. One other thing to consider will be if moisture sits in the area, like a low spot.

Fortunately, there are ways to test for all of this!
