Some flowers are incredibly vigorous, and they’ll take over the whole backyard if you don’t divide ‘em. Others grow better after dividing because you get rid of the old, weak growth that produces puny blooms and attracts pests and diseases. Best of all, dividing is a great way to get loads of beautiful new flowers for free!

And guess what? Early fall is best season for dividing crowded perennials! So get out there and start chopping away at those overgrown clumps.

Once you get your divisions in order, my Perennial Transplant Tonic will get them back on their feet without missing a beat. Here’s how to whip up a batch:

Mix 1 can of beer, 4 tablespoons of instant tea granules, 2 tablespoons of dishwashing liquid, and 2 gallons of warm water in a bucket. Soak your newly divided perennials in this tonic for about 10 minutes just before replanting them. When you’re finished, dribble any leftover tonic around your newly settled divisions to get ‘em off to a supercharged start.
