Chelesa chop love the name, and it helps your perennials. See what it is.

It’s hard to chop, but it works, and you’ll be happy once you see the renewed blooms! I ruthlessly chop off the top third or half of the New England asters and tall phlox in my front flowerbeds because they get so tall we can’t see out of the windows! I am a little more selective in the other beds, cutting back only about half the plants in a clump, leaving a few to grow tall and blossom earlier. The shorter ones help to support the leggy ones, lessening the need for staking, and hiding their “naked ankles,” the leafless stems at the base of the taller plants. this is the author's flower beds

Good morning.  Looks like a pleasant day as it is partly cloudy.  Rain is north of us so some of you might be getting that.  Humidity is down but there isn’t much wind.  High today 86F(31C) ENJOY, stay cool, stay safe. Classic summer day. 
 
Australia family and friends for July 8th will have a cool start at 39F(4C) but the daytime high of 58F(14C)   Wonder if this is a classic winter day for them?  See if they answer back with this.  Stay warm, stay safe,
 
I have talked about this before and I love the name.  CHELSEA CHOP  I do it to my annuals that have become overgrown and I know it works.  If you have overgrown foliage and the plant has stopped blooming give this a try.
 
How to Do the Chelsea Chop for Better Blooms  Written By:Robin Sweetser
What is the Chelsea chop? A new hairdo, dance craze, or fancy cut of meat? Nope, it’s just a pruning technique. By cutting back perennials in early summer, you can get better blooms over a longer period and stop your plants from becoming leggy! Here’s how it’s done.
 
The Chelsea Chop
The name “Chelsea chop” comes from the Brits because they do it around the time of the annual Chelsea Flower Show in May. However, for many areas, the timing is simply late spring or early summer. For me, it should be called the “4th of July chop,” since cutting the plants any later than that won’t give them enough time to recover and blossom before fall.
The whole idea is that 1 hour of pruning now will result in 3 more weeks of flowers at the end of their season! As well as extending the blooming season, you are controlling the growth and shape of your perennials for a better-looking, fuller, more compact plant. This pruning technique is especially suited to perennials that get too tall and leggy, such as phlox, aster, and sedum.

I usually just use my trusty kitchen shears to make random sharp cuts but you can use pruners, loppers, or even hedge clippers to get the job done faster.
If you are as frugal as I am, save some of the cuttings to root and make new plants! New England asters and phlox cuttings placed in a glass of water will produce new roots in no time. They can be potted up to share or planted out in the garden, where they often bloom the first year.
The Chelsea chop is best done on late summer or fall bloomers like asters, chrysanthemums, goldenrod, helenium, marguerites, nepeta, phlox, and rudbeckias. Since it encourages branching, the plants will be shorter, more compact, and have more flowers. By leaving a few tall ones to bloom earlier, you can extend the bloom time. Give it a try!
