I live in Idaho and had some black eyed Susans growing in my yard do I need to cut them?

Answer 1

You don't need to cut them back just yet. Many gardeners cut their perennials to the ground in the fall, which is fine. I would wait until spring though. They're one of the few perennials which are study enough to remain standing through the winter and still provide the garden with interest. Their seed heads look quite nice through the winter and provide food for birds. Here's an article I wrote for my site http://www.gardenlistings.com

Answer 2

leave them as they are. the dead foilage will collect snow and help to insulate the plant against cold, giving it a better chance of surviving the winter. remove the dead foilage in the spring after the snow melts. if the plants are only annuals, however, then you could remove them in the fall before it snows. A lot of different plants use the name "black eyed susan" (heliopsis, helianthus, rudbeckia)--- some are perennial and some are annual.

Answer 3

Leave them through winter and then in the spring cut all the dead off and wait for your new ones. You can also transplant some of it if it starts invading your other plants. Other wise you can just leave them alone to do their thing.

Answer 4

i never trimmed mine i just removed all the dead leaves and stuff in the spring.

Answer 5

i think that yo do need to becuase they can ruin the rest of your yard if you dont.

Answer 6

if you cut them to trim them then I would.
