Catnip dying yet again
I've posted on this catnip patch before, but apparently I'm still a gardening "noob" because I have no idea what I'm doing wrong here.
I'm having trouble with my catnip again - after it all died off last summer, it finally came back in the winter. The seeds that had fallen germinated and resulted in a beautiful catnip bed for my cats to play in.
Then I read somewhere on line that if you prune your catnip back it will keep growing year-round. So I trimmed all the plants. Oops. Now my catnip is dying off again.
Is this something that catnip "just does" every year? I wasn't aware that it was an "annual" - I thought it could live from year to year. Is it the late summer Arizona heat that's killing it? Have I over or under watered it? I've been very careful with it and haven't changed my watering or fertilizing routine (10 minutes a day and Miracle Gro All Purpose Plant Food every 2 weeks.) The only difference was the trimming I did.
What can I do to salvage this catnip, or do I need to wait and start over again this winter?
