| Should I prune my black eyed susans, and when? Is this true for most perennials? |
| You can remove the dried out stems and frost killed leaves in the late fall or in very early spring, depending on your preference, by cutting it off short. Leave any still-green basal foliage in place. Be careful not to damge new growth coming in if you leave the job until spring. I think this works as a rule of thumb for most perennials. |
