Once or twice a year
Depending on the variety, the flowering period of catnip usually begins in June and lasts until July. Some varieties already bloom in April. After the main flower the plant can be stimulated to a second flower.
It’s like this:
- cut all withered inflorescences
- After a few weeks new flower buds have developed
- the new flowers open and show up until autumn
Tips & Tricks
Cutting off the edible flowers has a positive side effect: Self sowing of catnip is avoided. For most gardeners self sowing is not desired.
