Catnip

Catnip is a perennial member of the mint family. It does attract beneficial wasps. However, it is most famous for how it affects most cats. It contains a chemical that many cats find very attractive.

Catnip

Growing Tips

Container Friendly

3 plants per 12” container

When to Start

 

Direct sow: After stratifying, direct sow after the danger of frost has passed.

 

How to Start

 

Catnip is only intermediate because the seeds need to be properly prepared before planting. The seeds are tough and need to be cold-stratified before they will sprout.

This can be done by first placing the seeds in the freezer overnight and then placing the seeds in a bowl of water for 24 hours. This process will damage the seed coat and will make it much easier for the catnip seeds to sprout.

After you have stratified the seeds, catnip is easy to grow. Direct sow in full sun with well-draining soil. Plant after the danger of frost is over. Thin to 18-20’’ between plants.

 

Care

 

Catnip can be aggressive in some areas so you need to take steps to control it. Catnip plants spread readily by seed so, to control their spread, you’ll need to remove the flowers before they go to seed.

However, catnip is very sensitive to waterlogging and should only be watered when the surface of the soil seems dry, and then water deeply. Pinch young growth back to encourage a more shrub-like appearance.

As many cats enjoy this herb, unless you are planting for felines, it might be wise to enclose some plants for your personal harvest. Don’t be surprised if neighborhood cats come to visit if you plant this herb.

 

How to use

 

To turn the herb into cat toys, the best time for picking is when the plants are flowering. this is around mid-summer. This is when the compounds that cats love are at their peak levels in the leaves.

Cut the leaves and tie them into small bundles. Hang upside down and fully dry. You can also place leaves on a screen to allow for good airflow. Drying can take a few weeks. Keep out of reach of cats or they will destroy the leaves.

Seed Saving

Instructions

 

Let your catnip flower dry out on the catnip plant. This will happen at the end of the season.

Cut the flower off the catnip plant with a pair of scissors. It is best to cut the flower off, rather than pull it. This is because the seeds will be dried out and any sudden movements could cause them to fall out.

Hold your flower over a paper plate. Turn it upside down and give it a few shakes. The seeds will come loose and land on the paper plate.

Use your fingers to spring loose any remaining seeds that did not come out when you shook the flow.
