Too funny -- my dad's family is from just outside of Pittsburgh - and for all the year's we've visited all I ever think is "Wow - Look at the Rose Of Sharon!". I was always impressed that in SW PA - its a TREE. In Michigan, where I grew up - more of a shrub.

However I did plant on in MI - and it got sizeable (8' tall, 5' wide) and after about 8 years - BABIES EVERYWHERE.

They were in Mulch, and easy to pull - but a PAIN!

In the lawn - I recommend using a weed killer. If the broadleaf weed killer doesn't work, you may need a brush killer (this won't kill grass - but targets woody plants).

Good luck! I enjoy looking at them when I'm in PA, and I might even plant them again in the future, but only in an area where I'd be willing to let them spread!!

I have one that I planted here 25 years ago. The amount of seedlings is no problem. I have transplanted some to other locations around our yard, and still have no problems. The few that are where I do not want them either get pulled or cut down.

They're easy to pull if the ground is moist after a rain. If you want a chemical solution, use a broadleaf weed killer as suggested above. If you do use roundup, get a paint brush and paint the leaves instead of spraying. You can be more selective that way.

I have a question about these. I have a bunch on one side of my property and find that they make a nice screen for privacy. I wanted to put them on the other side to hide a business that is behind the house.

How far from the fence should they be planted? It says they can grow up to 6 ft wide - does that mean circumference? Because the ones I have on the other side seem tall but thin. I was wondering if 2 1/2 to 3 feet from the fence would be far enough.

If you're going to mow around the althea (and since you said "lawn", it seems that you are), I don't see what the problem is. Mowing will kill the seedlings.

First, let me say I love rose of sharon!
Now having said that, I am rather frustrated . Between birds and wind, part of my (pebble) driveway has turned into a rose of sharon garden and because I did not pull them right away (had no one to give them to and I hate to destroy plants ) they are now really embedded in the ground and stones... So now I am faced with serious digging or excavating - let that be a warning to others dig and pull when they first appear, because those roots seem to go down deep!
Of course that's not the only thing that's now growing in my driveway

I haven't had much problem with the seedlings - the mower seems to take care of spread. That and the fact that we don't usually get enough rain to promote any abundance. Those that do survive are going to be used around the property, in the woods where I have dappled sunlight and wherever else I might want to draw the hummingbirds. Unfortunately mine are only either the white/red or light purple...have seen a solid red growing here and want one of those.

Had a few unusual, hybrid Hibiscus back in South Florida, was bummed to have to leave those behind, what wasn't in the ground was given to a good friend.

Pull them by hand...soak the roots in root solution...plant in containers...sell for $4-$6 a piece. Easy!

I have trouble giving them away, never mind selling them and I'm not talking about one foot seedlings either!

Ours are planted up against our fence about 12" (away from fence). We planted them 3-4 feet apart.They have been there 13 years. They are just now coming thru on the other side of the fence, no big deal, we just trim them. Our's are only about 4 feet wide at the thickest part of bush. We love them.
