How Quickly Does Catmint Plant Grow?

Updated: February 21, 2023

Catmint, also known as catnip or Nepeta cataria, is a popular herb that belongs to the mint family. This plant is not only beloved by cats, but also by gardeners because of its beautiful flowers and fragrant foliage. If you are planning to grow catmint in your garden, you may be wondering how quickly it will grow. In this article, we will discuss the growth rate of catmint and some tips on how to care for it.

Factors That Affect the Growth Rate of Catmint

The growth rate of catmint can vary depending on several factors. Here are some of the most important ones:

Climate

Catmint is a hardy plant that can tolerate a wide range of temperatures. However, it grows best in cool to moderate temperatures, around 60-70°F (15-21°C). If you live in a hot and humid climate, your catmint may not grow as quickly as it would in cooler climates.

Soil

Catmint prefers well-draining soil that is slightly alkaline with a pH level between 6.7 and 7.3. If your soil is too acidic or too compacted, it may hinder the growth of your catmint plant.

Watering

Catmint requires moderate watering, about 1 inch of water per week. Overwatering or underwatering can stunt the growth of your plant.

Sunlight

Catmint grows best in full sun to partial shade. Lack of sunlight can slow down the growth rate of your plant.

How Fast Does Catmint Grow?

Under ideal conditions, catmint can grow up to 3 feet tall and 3 feet wide within a growing season. It typically takes about 2-3 weeks for catmint to germinate from seed and another 6-8 weeks for it to reach its full size. However, the growth rate can vary depending on the factors mentioned above.

Tips for Growing Catmint

Here are some tips to help you grow healthy and thriving catmint plants:

Planting

Catmint is a perennial plant that can be grown from seeds or cuttings. If you are starting from seeds, sow them indoors in early spring and transplant them outdoors when the weather warms up. You can also plant catmint directly in the ground in late spring or early fall.

Soil Preparation

Before planting your catmint, make sure to prepare the soil by adding compost or organic matter to improve drainage and fertility. You can also add some lime to raise the pH if your soil is too acidic.

Watering

Water your catmint regularly, about once a week, especially during dry spells. Make sure to water deeply to encourage deep root growth.

Fertilizing

Catmint does not require much fertilizing, but you can apply a balanced fertilizer once or twice a year to promote healthy growth.

Pruning

Prune your catmint regularly to promote bushier growth and prevent it from becoming too leggy. Cut back the stems by about half their length after the first flush of flowers has faded. You can also pinch off the tips of the stems throughout the growing season to encourage branching.
