    The Rose of Sharon is likely suffering from a bit of shock, which is normal as the plant acclimates. You can cut it back some to alleviate some of the stress so that the plant can focus its energy on root establishment.

    I do not have this problem with my varieties of Althea (a.k.a., Rose of Sharon; Hibiscus syriacus) but this happened to a friend when the branches bent from the weight of the flowers; the branches get leggy and the canopy becomes top heavy. She tried to prevent this problem by pruning the bush in the winter or early spring but I never do so, oh well. If you provide some additional water during the summer and this does not help self correct the branches, you may need to prune them in early Spring.

    Rose-of-Sharon prefers full sun and appreciates protection from winter winds. Flowers are formed on current season’s wood so pruning, if desired, should be done either in late fall, in winter after leaves drop or in early spring before buds form. Note: if the trunk survives your WI winters and leafs out, there would be no need to prune. Tropical hibiscus (a.k.a. hibiscus rosa-sinensis) is frost tender is most of the U.S. and should be brought inside. Hardy hibiscus (a.k.a. hibiscus moscheutos) is typically winter hardy to z5.
