Why Fall is Suitable for Dividing Certain Plants

1. Dividing in the fall is profitable because it allows the plants to focus on root development before winter, ensuring they are well-established for a healthy and vigorous spring growth season.

2. The combination of mild temperatures, increased moisture, and plant dormancy makes it an ideal time for this horticultural practice.

3. Cooler temperatures typically result in fewer pests, which can enhance the survival chances of new divisions.

Using Suckers and Root Shoots

If you have a large plant in the garden, it would be impossible for you to take it out and divide the roots. In that case, you should use its suckers and root shoots to divide the plant.

  • Suckers are young shoots that emerge from the base of the lilac plant, usually around its root system. Gently dig around the sucker to expose the connecting roots to the parent plant. Cut the sucker away, making sure it has some roots attached. Immediately transplant the removed sucker into a prepared hole in the ground or a pot with good-quality soil. Water thoroughly!
  • Root shoots are similar to suckers but originate directly from the root system and may appear far from the parent plant. Locate a healthy root shoot and excavate the soil around it. Carefully sever the root shoot from the main root, ensuring you retain a portion of the root with the shoot. The same as suckers—plant immediately, water, and fertilize when new growth appears.

Plants to Divide in Fall – The Bottom Line

  • Know the average first frost date in your area and aim to complete the division at least 4-6 weeks before this date. This gives the plants ample time to establish their roots.
  • Only divide plants that are healthy. Signs of a good candidate include vigorous growth in the past season and no signs of disease. Generally, plants that are at least two to three years old are suitable for division.
  • In the weeks following the division, make sure to water deeply to encourage roots to extend further into the soil.
  • If an early frost is forecasted, consider providing protection by bringing your divided plants indoors if growing in a pot. Covering the newly divided plants with frost blankets overnight is a good idea.
