Tropical hibiscus 'Cinnamon Girl'

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.

A full sun position will ensure your plant thrives and remember to water moderately. Cinnamon Girl is generally regarded as a tender plant, so it is really important to plant out well after your last frost date.

By our calculations, you should look at sowing Cinnamon Girl about 84 days before your last frost date.

Cinnamon Girl is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
