How to extend Aster blooms

5 years ago

My purple asters are just starting to bloom. What kind of care do they need? Deadheading? Would like to extend bloom. The bloom time was very short last year. I did cut them back earlier this summer.

Stokes Asters not blooming

The plants go back about 8 years with additional volunteers starting around 4 years ago. All of those are not putting out buds. The volunteers that are blooming go back about 2 years. All my Stokes have started from 3 potted plants and kept spreading.

Wow, this was a surprise - aster Purple Dome in bloom!

Dee, Sorry, I don't have Purple Dome, so I have no experience with it to know if it is normal for it to start blooming in July. It is a very pretty aster, do you enjoy it and does it perform for you? I don't repeat cut the mums, because it's just an extra thing to do that I don't need. I wait until the end of June and then cut them once. I found one mum in the back that I missed this morning and it was over 2 feet tall and had buds on the tips, but not close to opening, so I am safe to wait for end of June to trim them without fear they will bloom before I cut them. That might be different for the variety you have. I cut them back leaving the lower two sets of leaves. This year I had help cutting them back and trying to speed it up, I told them to take handfuls and cut them, rather than one stem at a time. When I came back to look at it, the entire middle of the plant had bare stems with no leaves. But now they are producing new leaves and are going to fill in just fine. Yes, that is Euphorbia amygdaloides purpurea next to the orange mum. Unfortunately, it didn't make it through last winter and now I have a bare spot there that I haven't figured out what to do with yet. Too bad, I really liked that combination and would have added more.

Think there's any point to deadheading asters?
Q

I think it is too late to get a second flush. I have tried deadheading them before and couldn't see much benefit other than keeping them neat. I do as old roser does and cut them back in stages to stagger and extend the bloom: works very well. I still have blooms on mine and it's been going for over a month. Keep that in mind for next year.

Aster frikartii v. the other tall asters?
Q
Comments (1)
You'll be much happier with the A. frikartii if you don't assume it is going to be tall, and let it flop. It is much closer to a scabiosa in appearance than a tall aster, and compares quite favorably to those short lived perennials.

Hang on with no care, Ken? or do you deadhead?

because its starts getting real cold ... they end up in suspended animation .... for lack of a better term ...

flowers last forever .. and even if you did deadhead,... its too cold for them to actively regrow buds.. let alone flower ... due to lack of time ...

i presume your zone is rather equivalent ...

as always.. if you have more than one.. or even a large plant ... deadhead some.. of half of one.. AND REPORT BACK ...

and just to be sure.. we are talking asters.. not mums .. wait.. same either way .....

they just arent going to be growing with vigor.. during 60 degree days.. and 40 degree nights.. not to mention cooling or cold soil temps .... yeah. its coming.. lets not delude ourselves.. lol ...

also.. i presume.. the warmer the zone.. the more different the answer might be ...

We have New England asters, Alma Pötschke and 'Purple Dome', smooth aster 'Bluebird', calico aster 'Lady in Black' and white wood aster (only latter in bloom now). I may trim ours up a bit over fall, but don't think deadheading extends their time of bloom.

Not sure, but judging from my photographs, roughly from earliest October to mid October.

The Arend's (fall) monkshood is still blooming into November.
