How to divide perennials
One of the things that makes perennials so attractive to home
gardeners is the ability to divide and transplant the
perennials. Gardeners can use cuttings made from their
perennials in order to create new growth, share their plants
with family members and friends, or even to sell excess stock to
nurseries, garden centers and flower stores.
There are basically two reasons why gardeners choose to divide
their perennials. The first reason is for the improvement of the
health of the plants, and to encourage those plants to produce
more flowers. In many cases, an older planting of perennials
will become overgrown, and this can cause the bloom quantity of
those perennials to drop considerably. The other reason
gardeners divide perennials, of course, is to create new
plantings. Perennials can be divided easily, and these new
divisions can be used to create plantings in other parts of the
garden, or even in another garden patch.
Even though many perennials can be divided easily, not all can.
In generally, division is most feasible on those perennials that
grow in clumps, and those that have an expanding root mass.
Perennials that grow from single taproot, on the other hand
usually cannot be divided. That is because any attempt to divide
the taproot can cause the plant to die. Those perennials that
grow from a taproot should be increased by using root cuttings
or seeds instead of division.
The best time to divide those spring and early summer perennials
that can be divided is generally in the fall of the year.
Perennials that bloom in the fall or late summer should be
divided in the spring instead.
To divide perennials, the ground around the plant should first
be gently lessened with a spading fork. The clump should then be
sliced with a garden trowel and then divided into four parts.
Those four sections should then be broken by hand to create
sections four inches by four inches. Those small sections should
then immediately be transferred to a previously prepared plant
bed.
It is important for the gardener to thoroughly wet the soil a
day or two before the division is to take place. Watering
thoroughly will make it easier to dig the clump. In addition, it
is important to add compost or other organic material to the
soil. The organic material should be added to both the original
plant and the new divisions. Doing so will give the plant the
nutrition it needs and help them to thrive better in their new
location. The plants should also be watered thoroughly and fed
with a good quality fertilizer once they have been planted.
