Fall Garden

Spring Divisions Caring for Your Flower Beds Budget Gardening: Increase Stock with Cheap or Free Garden Plants
Some perennials do best if divided in the spring, some do best if divided in the fall, and others may be divided in either fall or spring.
The following may be divided in the fall with good results. I think you will be surprised at how many perennials can be successfully divided in the fall!

Propagation by division assures the new plant will be an exact match with the original.
Division is an inexpensive way to increase your stock of a favorite plant, or to create extra plants for swapping with friends.

1 Dig up the clump, taking care to get as much of the roots as possible without damage.Most roots are in the top 12 inches of soil, and the root’s mass will usually be the diameter the plant plus 3 to 6 inches beyond the plant. For digging and transplanting, going larger than this shouldn’t be necessary.

2 Use a sharp spade to cut or cleanly break the clump into two or more pieces (divisions), each with an obvious growing point and some roots.Work on the clump quickly so the plant parts don’t dry out too much (you can cover them with a tarp or mist them occasionally if need be). Discard any unproductive portions and any shriveled or rotten parts. Leave the roots surrounded with the soil to protect the root hairs from drying out and becoming damaged.

You can pry apart fibrous-rooted perennials with your bare hands; all others require sharp, strong, clean tools that are equal to the job: a stout knife, a trowel, even two spades or gardening forks braced back-to-back.

3 Replant the new pieces.Plant some in the same spot and the others perhaps elsewhere in your yard (or share them other gardeners).

Many perennials can be left in place for at least several years before they need dividing
-- and a few such as peony and baptisia -- rarely need dividing, if ever. But if you have plants that need to be divided, see if they are listed. If so, do it this fall and both you and your plants will get a good jump on spring!
