Q. Potted Rose of Sharon winter care

I received a young rose of Sharon plant from a friend, about 1 foot tall now, that I would like to grow in a pot to put on my patio. I would like to know if it would survive the winter here in Newmarket, ON, which is zone 5a. If it is too small to survive in a pot, what should I do with it for the winter? This is my first rose of Sharon tree, so any detailed advice would be appreciated. Thanks!

Your Canadian zone 5 will be the equivalent to our zone 4. They will not survive the outdoors very well. They are only suited to our zone 5, which is your zone 6, so you will be a little too far outside of their native range.

I would keep this as a container shrub, and maintain the root size to fit a large pot.

This article will help you to prune this shrub, which you will do along with trimming the largest roots out completely each year during the winter when you repot: https://www.gardeningknowhow.com/ornamental/shrubs/rose-of-sharon/pruning-rose-of-sharon.htm

Q. Few yellow leaves appearing on newly planted Rose of Sharon (Hibiscus)

We have a lovely hedge of Rose of Sharon in our yard. Several were lost this past winter storm here on the south shore of Massachusetts. They are a very hardy plant specimen so at a lost for what’s going on…. have given it a slow releasing fertilizer.
Any input would be most grateful. Thank you!

A new planting with yellow leaves; it is likely watering issues. Either too much or too little.
Daily water will be needed for the first few weeks, then you can taper off.

Q. Why are gray squirrels eating Rose of Sharon bush?

We have a Rose of Sharon Bush that normally produces abundant blossoms in late summer. This year and last I’ve noticed gray squirrels chewing on the leaves as well as the buds and blossoms. Do you know why the squirrels would be doing this and how to stop them? I’ve tried using spray-on animal repellent, to plants, but it doesn’t stop the squirrels.

Thank you for your help.

Squirrels often will nibble buds on plants to get at seeds or soft centers. Have you tried the pepper spray? There is a commercially prepared one. Spray it on all the leaves, buds and flowers. Here are more suggestions:

It is very likely that it has run out of fertilizer. This should be done several times per year to keep it blooming properly. They are heavy feeders. This article will help: https://www.gardeningknowhow.com/ornamental/shrubs/rose-of-sharon/rose-of-sharon-not-blooming.htm

Q. rose of sharon trunk rot on bottom back

It looks like my rose of sharon has trunk rot on back bottom thats on the back & the leaves are wilting. I tried giving it lots of water because it’s been very hot. But the leaves are still hanging. So, I inspected the trunk & found this large area of what appears rotted trunk in the back that looks dark & feels soft when touched. Can this bush be saved?

It could be a root rot since there seems to be a problem with the water uptake. Cotton root rot is a problem with rose of Sharon but not normally in your area. Here is more information:

Q. What is the best time to trim a rose of sharon.

The pictures attached show my rose of Sharon, I would like to trim it back and reshape it. What would you suggest?

The best times are in late fall or winter or in spring before buds form. But they bloom on new wood so that gives you other opportunities, too.

Q. Rose of Sharon

I have many Rose of Sharon. Some of the plants have a lot of buds and bloom well, others have a few blooms and many buds that did not open. Is there something I can do for next year to resolve this?
