Hibiscus for Northern Gardeners: Tropical, Perennial, and Rose of Sharon

    We have had a Rose of Sharon for several years. It is healthy and gets lots of clusters of buds. However, the buds have never opened. They eventually brown and fall off ! No one has been able to solve the problem. Any suggestions?

      Hi Susan! This is a great question. We suspect that it’s a cultural issue – i.e. the plant is not liking something about it’s site or positioning. Is it by an irrigation system or by a spout where it’s getting too much water? Is it planted too deeply? Is it heavily mulched? Have you used any fertilizer on and it and what kind? Our guess would be too much water – but let us know more and we can advise better.

    It is often so tempting to bring tropical plants into the landscape, especially in summer. Often we need to consider these plants short-term visitors to the garden, as they will not survive plummeting temperatures. Tropical hibiscus may succumb to occasional freezes in zone 8 and should be kept in containers and moved indoors for winter or treated as annuals.

      Very true!
