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 might be a Turks cap

    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!

    I cut back my hardy hibiscus (3 separate bushes) down as I usually do in the spring but because I’m home from working at a school with theCovid situation, I cut it down a few weeks earlier than I would have but I really don’t remember when I usually see plant growth. As of this moment (May 22nd) I see NO growth. I’m hoping it may be because both April and early May were cooler than usual months here in the northeast US (outside of Rochester, NY). How will I know if it died?

      Hi Linda. I have great news – don’t worry. It’s still early. Those plants sleep in VERY late, and then grow like crazy once they wake up. So give it more time – even weeks really – because they really do wake up late.
