Catmint in the Fall: Preparing Nepeta Plants for Winter Dormancy

As the days grow shorter and the temperatures begin to drop, it's time to start thinking about preparing your Nepeta plants for winter dormancy. Catmint, as it is commonly known, is a hardy perennial that requires some special care to ensure it survives the cold season and comes back strong in the spring.

1. Cut Back Catmint Stems

One of the first steps in preparing your Catmint plants for winter is to cut back the stems. Use a sharp pair of pruning shears to trim the stems back to about 2-3 inches above the ground. This will help prevent the plant from becoming too woody and encourage healthy new growth in the spring.

2. Divide Overgrown Catmint

If your Catmint plants have become overcrowded or overgrown, fall is the perfect time to divide them. Carefully dig up the plant and use a sharp knife or shovel to separate the roots into smaller sections. Replant the divisions in a new location or share them with friends and neighbors.

3. Mulch Around Catmint Plants

Applying a thick layer of mulch around your Catmint plants can help protect the roots from freezing temperatures and excessive moisture. Use organic mulch such as shredded leaves or straw to insulate the soil and keep the plants healthy throughout the winter.

4. Water Catmint Plants Sparingly

While Catmint is a drought-tolerant plant, it's important to water it sparingly in the fall to help prepare it for winter dormancy. Avoid overwatering, as this can lead to root rot and other issues. Water deeply once a week if there has been no significant rainfall.

5. Monitor Catmint for Pests and Diseases

Before the cold weather sets in, take the time to inspect your Catmint plants for any signs of pests or diseases. Look for chewed leaves, wilting foliage, or unusual discoloration. If you notice any issues, treat them promptly to prevent further damage to the plants.
