Tropical hibiscus are highly sensitive to phosphorus (the middle “P” number on fertilizers) and an excessive amount will kill the plant. Do not use so-called “bloom fertilizers” on them. Instead tropical hibiscus need a lot of potash to bloom properly (the last number or “K” on fertilizers). Palm fertilizers are widely available and usually have the proper ratio of a medium-low-high NPK ratio along with needed minors.
The pesticide malathion will defoliate tropical hibiscus. Do not use it for pest control.
Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Happy-go-lucky is thought of as half hardy, so remember to protect this plant from frosts and low temperatures.
