Spring Cleanup Question
I hope someone can answer because I don't want to do any damage to my plants. Last year I started a bunch of flowers from seed indoors under lights and planted them out in my bed. They did great, although many did not bloom 1st year as expected. I did no cleanup or cutting back during the fall. I piled a bunch of leaves over the bed for winter protection and now that the snow has melted, I see that many of the plants still have a touch of green on the leaves (albeit a nasty looking green). Do I cut these plants back to the ground to make room for new growth? Off the top of my head, the ones I'm concerned about hurting with my pruning would be shasta daisies, columbine, dianthus, achillea and flax.
Oh, and I had 2 lavender plants make it through the winter too. Any suggestions on how or if to prune them?
