Is it important to plant rose of sharons deeply? mine still look like twigs two years later.?

I planted some rose of sharons that were given to me a couple of years ago. they still look like immature plants. they hardly get flowers on them. they basically look about the same exept a little taller maybe. the person who gave them to me didn't plant them vary deep and i wondered if that might be the issue? I have been reading about rose of sharons and everyone says how they spread and how easily they grow. What am i doing wrong?

Trees and shrubs should always be planted at the same depth they were before they were dug up. Planting them too deeply is just as bad as not planting them deep enough.





Wait until the plants have gone dormant (after a hard freeze and all the leaves have dropped) and transplant your ROS. Dig a new hole for it that is a little larger than the rootball and not quite as deep. Add some compost when refilling the hole. The top of the rootball should be about 2" above ground level. Now here's the trick: Mound at least 2" of topsoil over the rootball. This will allow for good drainage so your ROS won't drown. Then apply some mulch, about 2", over the topsoil, but don't pile the mulch up against the trunk.





After it is replanted, do a little pruning. The pruning will encourage the plant to branch out. ROS bloom on new wood, so when it is pruned that encourages the plant to produce more new branches in the spring. More new wood equals more blossoms, so prune that ROS every winter.
Reply:I have had them for a long time and they do spread like crazy. They have never been very fussy about sunlight, watering, lack of fertilizer, or soil quality. Even the volunteer ones that started from dropped seeds grew about 6 foot high in a few years. I am stumped.
