I was given a Rose of Sharon (apporx. 6′ tall) that seems to be suffering. It gets almost full-sun (direct sun morning, and late afternoon). My soil isn’t great, I’d call it dirt. With some Triple Mix thrown in. I haven’t been watering it since it’s been raining so heavily. Is it shell-shocked from being transplanted? The leaves are droopy, and wilting. It’s still flowering like mad. Anything I can do to make it happier?
The picture was taken as it was planted, it’s droopier now. It was from a recently purchased old house with a very neglected yard.
Sounds like your Rose of Sharon could be in shock from transplanting. Transplant shock can show symptoms for up to two years after the planting date; later symptoms include reduced plant growth, small new foliage and shortened branch tips.
According to Jacqueline Walker, author of Hibiscus (Firefly Books) Rose of Sharon (Hibiscus syriacus) “prefers full sun, good drainage, water during the growing season, organic feeding, and their roots away from competition from other plants.”
Since your soil is poor try amending with compost and add a two-to-three inch layer of mulch to help retain moisture. Check the soil regularly, and if the soil is dry as deep as 3 or 4 inches, it’s time to water the tree. Water deeply. After the Rose of Sharon is established in its new location, it can be treated as a drought-tolerant, mature tree.
The hole you planted it in should have been at least twice as wide as the root ball for best results. If it was not you might try replanting it.
