How to grow the rose of Sharon into a hedge?

[kevin101]

I have one year old rose of Sharon grow from seeds. They are planted into a straight line for hedging.
But they all have one single tall stem now. How do I prune them into a hedge?
should I top off the single stem?

Yes, you will need to prune the main stem low to encourage multiple branches from near the base.
Will the appearance of a deciduous hedge in Winter work in the setting you intend to plant?

Rose-of-Sharon (Hibiscus syriacus) is a deciduous shrub in the Mallow Family (Malvaceae), native to China and Taiwan.
Many cultivars have been selected and are grown widely in temperate regions.

Then when the other branches come out you can tip prune them and they too will begin to multibranch. They can grow pretty wide, mine are at least 3 feet from the trunk. They are never as dense as most hedge shrubs though, so it is a unique choice, between losing leaves and not being compact or dense.

I advise keeping the hedge rounded, loose, and informal.
I would advise that even with a fine-leaved evergreen hedge, but even more so with Hibiscus syriacus.
