When should I remove the mulch from my roses?
Also question is, should I put mulch around my roses?
Roses do best with uniform soil moisture throughout the growing season. The use of mulch around roses to help retain soil moisture is a practice that is highly encouraged. Mulch will also help keep soils cool and help retard weed growth. Materials such as wood chips, straw, or dry grass clippings make good mulches.
In respect to this, should you remove leaves from flower beds in spring?
If you keep leaves from compacting or blowing away, you need not remove them from your flowerbeds until spring perennials begin to grow.
The answer is indefinite. You can cultivate the existing mulch before adding the new layer, provided that there is no sign of any fungal disease. Cultivating helps loosen the mulch and allows rain to get into the soil. Depending on how much is needed for a new mulch, old mulch must never be removed.
