Aster flowers are available in both annual and perennial varieties and come in many beautiful colors such as blue, purple, white, red and an assortment of pinks. While there are many colors of the aster flower, the center of all asters is yellow. These beautiful flowers make a great addition to any garden or landscape, and are easily propagated and transplanted. So, here is a step-by-step guide on how to transplant aster flowers.

Step 1 - When to Transplant

As with many varieties of annuals and perennials, aster flowers should be divided and transplanted in the early spring. You should wait until the last frost before division because young asters are very susceptible to cold weather or frost.

Step 2 - Digging up the Plants

Use a small garden spade to gently dig out the aster plant. Try to remove as much of the root system as possible. If you must cut roots, make sure that you make clean, sharp cuts as far away from the root ball as possible.

Step 3 - Dividing the Aster Plant

Once you remove the aster flower from the soil, divide the plant's root ball into three or four sections. You may be able to separate the roots by hand or you may need to use a pair of scissors to accomplish this. Once you separate the roots, gently shake off any loose dirt or soil that clings to the clump.

Step 4 - Choose a New Location

When choosing a new location for your aster divisions, make sure that you choose a spot that gets direct sunlight for at least 6 to 8 hours a day. Some varieties of aster will grow in the shade, but won't have as many flowers.

Step 5 - Prepare the Soil at the New Location

Prepare the soil for your new aster divisions by turning it with compost and animal manure. If you do not have animal manure available, you can choose to use super phosphate, which can be purchased at home improvement stores and garden nurseries.

Step 6 - Plant the Divisions

Dig holes that are the same depth as those that were used with the parent aster plant and insert your new aster divisions. Gently pack soil around the divisions so that the plants stand upright, but do not pack them too tight that you damage the stems of the plant. Also, make sure to space the plants about 6 to 8 inches apart for smaller varieties and 18 inches to 24 inches apart for a giant sized asters.

Step 7 - Fertilize the Divisions

Apply a quality all-purpose fertilizer to the soil of your new plant divisions. It is also a good idea to add mulch at this time to help protect the new seedlings from insects and pests.

Step 8 - Water the Aster Divisions

Water the new aster plants thoroughly, but make sure not to water them too much. Give them enough water to keep the root system moist, but not too wet. After the asters are established, you will generally only have to water them if there is an extended drought.

Step 9 - Second Fertilization

You should apply a more all-purpose fertilizer about three or four weeks after you plant your aster divisions.
