Fall/Winter Care for Luna Red Hibiscus - Knowledgebase Question

Tucson, AZ
Question by gradiance3g

The instructions that came with our hibiscus don't specify how often to water during the fall and winter. Our plant is outdoors in the ground. Also, from what I understand, it needs to be pruned around the beginning of February. Is that correct, or should it be done earlier? Here in Tucson, the ground rarely freezes. Also, the instructions say to prune it to the ground. Is this necessary, or can it be only partially pruned? Thanks for your help.

Hibiscus thrives in your growing region. It isn't necessary to prune it down to the ground; instead, prune it back by about one-third to keep the shrub bushy and dense. Growth slows or stops during the hottest months of the year, but should have started again in early October so now's a good time to prune off any long stems and even out the look of your shrub. You can prune anytime the plant is growing (which is nearly all year around). When temperatures cool in December and January, you won't see much growth so you won't need to prune; when growth begins again in February, you can prune it again. Hope this answers your question!
