Why does the foliage all look so dead on my catmint plant after blooms fade? The plant looks healthy and beautiful in the spring and around and of June they look horrible. All leaves start to turn brown and crispy from the bottom up.
Foliage Looks Dead on My Catmint Plant
Certified GKH Gardening Expert
I just actually walked around the garden where I have my Catmint planted!
After the flowers have faded I find that the foliage also begins to fade. I cut my plants down to about 8 inches from the ground.
I have been able to encourage a 2nd blooming from my plants the last two summers by doing this.
You could give the plants a light feeding of an all purpose fertilizer after cutting back.
