Hibiscus rosa-sinensis

How to grow Tropical hibiscus 'Rose Flake'

  • Full Sun

  • Medium

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.

An excessive amount of nitrogen given to this cultivar will revert the variegated leaves to green.

Cooperi is more cold tender than most tropical hibiscus cultivars and care needs to be taken in marginal areas as a result. 1

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Rose Flake is thought of as tender, so it is imperative to wait until temperatures are mild before planting out of doors.
