garden phlox/ monarda deadlheading
I purchased a number of phlox plants and two butterfly bushes this year.
Phlox are finishing their blooming cycle, and I would like to know how to encourage more blooms. Some are on rather large plants, and still blooming. Most that are new have had the single clump of blooms and are finished. Do I just break off the blooms, or do I cut them down an inch or two to try to encourage more growth?
Two monarda. They were a clump in a pot. They finished their bloom, and are sitting there. I took off the blooms, and some of the stems are dying. Also the plant never grew much. I always thought they were supposed to bloom all summer. From this weak description do you have any suggestions? Otherwise I will replace them, and think I did not really purchase a perennial.
Thanks for any suggestions.
