Cutting back fall Asters?

Hanson, KY(Zone 6a)

Hi,
I have several fall asters that were so beautiful this year, seems like I have read somewhere to cut these back after blooming, but of course I can't find where I read this now.
Should they be cut back and if so how much?

Well I dont know what happens in Ky over the winter but I cut my asters down to about 6 inches after they have bloomed (or after it snows/freezes!) That catches the snow and in the spring I trim the stalks right to the ground.

Good info, I have asters for the first time this year, and was wondering the same thing. Thanks for the advice.

Jane,
Do they grow from cuttings? If so and you have some cuttings I would love to have some. I don't have asters with the exception of the stokesia blue...would like to have some...
Thanks.

Asters are very similar to mums. I do the same for asters as I do for mums. Trim them 2-3x and then leave them alone from July onward. In the fall after they bloom, trim them back to like 6-8" and mulch them good.

Janet, I got seedlings all over the place too, if you are intersted.

I would love some!!! Let me know what the postage will be and I will send it out...thanks so much! What colors do you have? Carol, that is so sweet!

They are purple and I will have to look and see if I have any babies from the white aster. Too bad I didn't know last weekend then. I did pull up some larger seedlings when I was trying to pull out a plum tree rootball.
I will look around this weekend and let you know more then. Remind me please!

Wonderful! I love purple and I always need more white in the garden! Thanks so much for the offer! I seem to see a lot of the blue and pink this time of year here... about three feet tall or maybe more and have flowers that are three or four inches across, they are just beautiful..I have never seen them for sale, just in peoples yards...I may have to stop and ask for seed sometime...they will most likely think I am crazy!
LOL but that is okay too.

I looked in the yard tonight. Found some seedlings that I can send you. The white one, I only have like one seedling. I can divide that plant if you want. It is pretty big. Do you want that then too?
I have always asked people and they don't seem to mind. Yes, we are crazy but it keeps us out of other trouble, LOL

Yes Carol, that would be wonderful...thanks so much for sharing with me...do you want me to send postage now or wait till it comes..just let me know what works for you.

OK, now how about Sheffield Pink Chrysanthemums? Do they need to get cut back too?

Ok, Janet, I will let you know the postage cost after I ship it.

Carrie, I think all mums need to be cut back.

Braselton, GA(Zone 7b)

I cut mine back to the ground almost after they are done..and then cut them back by about half when they are about eight inches high, twice while growing..they are pretty and full in the fall after doing this..I only have the yellow, but I love the show they put on...

Menasha, WI(Zone 5a)

Janet - you have yellow asters? What kind are they?

Braselton, GA(Zone 7b)

I have yellow mums...I will take a picture of them if you would like..

Menasha, WI(Zone 5a)

Ok - that's different, I thought asters didn't come in yellow ;) You don't need to post them - thanks.

Sorry for the confusion...

I'm sure it doesn't hurt to cut them back in the fall, but I leave most of my perennials till spring to cut back. This way they can self sow, the birds can eat the seeds, and I can enjoy my winter garden on those special days of ice and frost that turn everything into a crystal fantasy world.
You can dig up a piece of aster root from the outside of the plant after they bloom, cut back the foliage and replant. This is how I got the wild asters that we have here to grow in my garden. In a garden asters will self sow, but in the wild there is so much competition from grass, etc. digging a piece of the root is a surer way to get one going.

Ok, Janet, got you some nice rooted plants of both colors, I think. Will send them tomorrow priority. You should get them in 2-3 days.

Thanks so much! I will get the postage out as soon as I get them!

Many years including this one my asters have turned brownish. Is this from the heat and not enough water? I don't water very often because we are on a well. I didn't think they required alot of water.

Thanks

Carol, I have been meaning to tell you how much I have enjoyed the asters you sent me last year! They have bloomed all year and just keep getting more blooms...I could not remember who sent them so I could send a picture to show them off...here is a picture I took when they began blooming...both the blue and the white have been going strong!
Here are the blue in June.

Actually I have about 4 or 5 Asters for about 2 years now. I cut mine back in the spring. I leave them to catch snow for that is supposed the best winter mulch correct?? Mine come back or have every year since I first planted them in the fall of 2005. i pinch them back once a week in June and first couple weeks of July and get loads of blooms that don't need to be staked.

Janet, am glad you have enjoyed the asters. Yes, they can just keep blooming and blooming!

I heard 'pinch them back until the 4th of July'. Sometimes I'm not really sure which are the asters until the 4th of Sept. so they don't all get pinched!
