How to Grow Catmint Plant Outdoors

Catmint, also known as Nepeta cataria, is a popular herb and ornamental plant that belongs to the mint family. It is a hardy plant that is easy to grow and care for, making it an excellent choice for beginners and experienced gardeners alike. In this article, we will cover everything you need to know about growing catmint plant outdoors.

Choosing the Right Location

Catmint plants require full sun to partial shade to thrive. Therefore, it is essential to choose a location that receives at least six hours of direct sunlight per day. If you live in a region with hot summers, it is best to plant catmint in a spot that receives partial shade during the hottest part of the day.

Soil Requirements

Catmint plants prefer well-draining soil that is rich in organic matter. Before planting catmint, amend the soil with compost or well-rotted manure to improve its fertility and drainage. A pH level between 6.0 and 7.5 is ideal for catmint plants.

Planting Catmint

The best time to plant catmint outdoors is in the spring, after the last frost date in your area. You can also plant catmint in the fall, about six weeks before the first frost date.

Here’s how to plant catmint:

1. Dig a hole twice as wide and deep as the root ball of your catmint plant.
2. Mix compost or well-rotted manure with the soil you removed from the hole.
3. Place the catmint plant in the hole and backfill with soil.
4. Water thoroughly.

Watering Catmint

Catmint plants do not require frequent watering once they are established. Water them deeply once a week if there has been no rainfall, allowing the soil to dry out between watering sessions.

Fertilizing Catmint

Catmint plants do not require heavy fertilization. However, you can apply a slow-release fertilizer in the spring to encourage healthy growth and flowering.

Pruning Catmint

Pruning is essential for maintaining the shape and health of your catmint plant. Deadheading spent flowers and cutting back straggly stems will promote bushier growth and more abundant blooms. Prune your catmint plant in the spring before new growth emerges.

Pests and Diseases

Catmint plants are relatively pest and disease resistant. However, they can be susceptible to spider mites, aphids, and powdery mildew. Keep an eye out for these pests and diseases and treat them promptly if you notice any signs of infestation.

Harvesting Catmint

Catmint leaves and flowers are edible and can be used to make tea or added to salads. Harvest the leaves and flowers when they are at their peak, usually in mid-summer. Cut the stems just above a set of leaves to encourage branching and new growth.

FAQ

Can I grow catmint in a container?

Yes, catmint plants can be grown in containers as long as the container is at least 12 inches deep and wide enough to accommodate the plant’s root system.

Is catmint invasive?

Catmint is not considered invasive but can self-seed moderately. Removing the spent flowers before seed production can help control its spread.

How often should I fertilize my catmint plant?

Apply a slow-release fertilizer once a year in the spring to promote healthy growth and flowering.

In conclusion, growing catmint plant outdoors is a straightforward process that requires minimal maintenance. By following the tips outlined in this article, you can enjoy beautiful blooms and delicious tea from your catmint plant for years to come.
