Updated: April 29, 2022

The Cat’s Pajamas plant, also known as Nepeta faassenii ‘Cat’s Pajamas’, is a popular perennial herbaceous plant that belongs to the mint family. It is known for its beautiful lavender-blue flowers, which bloom throughout the summer and attract bees and butterflies to your garden. However, one of the biggest challenges of growing this plant is preventing it from rotting. In this article, we will discuss some effective ways to prevent Cats Pajamas plants from rotting.

What Causes Cat’s Pajamas Plant Rotting?

Before we get into the prevention part, let us first understand what causes Cat’s Pajamas plant rotting. One of the main reasons for the rotting of this plant is overwatering. When the soil is constantly wet, it leads to root rot and eventually kills the plant. Another reason for rotting is poor drainage. The Cat’s Pajamas plant needs well-draining soil to grow healthily. If the soil does not drain well, it can cause waterlogging, leading to root rot.

Prevention Tips

Here are some tips that can help you prevent your Cat’s Pajamas plant from rotting:

1. Watering

The most crucial step in preventing rotting of your Cat’s Pajamas plant is watering it correctly. Always check the soil moisture level before watering the plant. Stick your finger into the soil up to your first knuckle; if you feel the soil is dry at that level, then it is time to water the plant.

Also, make sure not to overwater the plant as it can lead to root rot. Watering once a week or when necessary is enough for this plant. Ensure that your pot has drainage holes so that excess water can drain out.

2. Soil

The Cat’s Pajamas plant prefers well-draining soil. Ensure that the soil you use has good drainage properties. A mix of garden soil, sand, and peat moss in equal parts can be an excellent choice for this plant. Avoid using heavy soils like clay as they do not drain well.

3. Potting

If you are growing Cat’s Pajamas plants in pots, ensure that the pot has proper drainage holes. Make sure to select a pot that is slightly larger than the plant’s root ball so that it has enough space to grow.

4. Sunlight

The Cat’s Pajamas plant prefers full sun or partial shade. Ensure that the plant receives a minimum of six hours of sunlight per day. If the plant is not getting enough sunlight, it can lead to damp conditions that can cause rotting.

5. Fertilizer

Fertilizing your Cat’s Pajamas plant can help it grow healthy and strong, but over-fertilization can lead to root rot. Use a balanced fertilizer once a month during the growing season, and avoid fertilizing during the dormant season.
