Updated: March 29, 2022

If you’re a plant lover, you know how frustrating it can be when your beloved greenery starts to wilt or die. One of the plants that has been causing concern among gardeners and plant enthusiasts is the Cat’s Pajamas plant, also known as Nepeta faassenii.

If you’ve noticed that your Cat’s Pajamas plant is dying and you’re not sure why, don’t worry. In this article, we’ll explore some common reasons why this plant may be struggling and provide some tips on how to revive it.

Understanding the Cat’s Pajamas Plant

The Cat’s Pajamas plant is a member of the mint family and is native to parts of Europe and Asia. This perennial plant typically grows to be about 18-24 inches tall and has small, blue-violet flowers that bloom in the summer.

One of the reasons why this plant is so attractive to gardeners is that it’s low-maintenance and relatively easy to care for. However, there are still a few factors that can cause it to struggle.

Common Causes of Cat’s Pajamas Plant Death

Here are some of the most common reasons why your Cat’s Pajamas plant may be dying:

1. Overwatering

One of the most common causes of plant death is overwatering. The Cat’s Pajamas plant prefers soil that’s well-draining and doesn’t like to sit in water for extended periods. If you’ve been watering your plant too frequently, it may have developed root rot, which can cause it to wither and die.

2. Underwatering

On the other hand, underwatering can also cause your Cat’s Pajamas plant to die. This plant prefers soil that’s moist but not waterlogged, so if you’ve been neglecting to water it or haven’t been watering it enough, it may be struggling.

3. Poor Soil Quality

The Cat’s Pajamas plant prefers soil that’s rich in organic matter and has a pH between 6.5 and 7.5. If your soil is too acidic or alkaline or lacks nutrients, your plant may not be able to absorb the nutrients it needs to thrive.

4. Pests and Diseases

Like all plants, the Cat’s Pajamas plant is susceptible to pests and diseases. Common pests that can affect this plant include spider mites, aphids, and whiteflies. Diseases like powdery mildew and root rot can also cause your plant to die.

How to Revive a Dying Cat’s Pajamas Plant

If you’ve identified the cause of your Cat’s Pajamas plant’s decline, here are some steps you can take to revive it:

1. Adjust Your Watering Schedule

If you’ve been overwatering your plant, allow the soil to dry out before watering it again. If you’ve been underwatering it, make sure to water it more frequently.

2. Improve Soil Quality

Amend your soil with compost or other organic matter to improve its texture and nutrient content. You can also test your soil’s pH level using a soil test kit and adjust it as needed.

3. Treat Pests and Diseases

If you suspect that pests or diseases are affecting your plant, treat them with an appropriate pesticide or fungicide. Be sure to follow the instructions on the label carefully.

4. Provide Proper Lighting

The Cat’s Pajamas plant prefers full sun but can tolerate partial shade. Make sure that your plant is getting enough light for its needs.


Do I need to prune my Cat’s Pajamas plant?

Yes, pruning your plant can help promote healthy growth and prevent it from becoming too leggy. Cut back the stems by about a third after the first flush of flowers has faded.

Can I grow Cat’s Pajamas indoors?

While the Cat’s Pajamas plant prefers full sun, it can tolerate some shade. If you’re growing it indoors, make sure to place it near a sunny window or under a grow light.

Can I propagate my Cat’s Pajamas plant?

Yes, you can propagate your Cat’s Pajamas plant by taking stem cuttings in the spring or fall. Dip the cuttings in rooting hormone and plant them in moist soil. Keep the soil moist and provide bright, indirect light until the cuttings have rooted.

In conclusion, the Cat’s Pajamas plant is a beautiful and easy-to-grow perennial that can add color and interest to any garden. If you’ve noticed that your plant is struggling, don’t worry – with some proper care and attention, you can revive it and enjoy its beauty for years to come.
