March: Maintenance
Cut back or Prune by mid-March:
- Ornamental Grasses
- Liriope
- Perennials
- Roses - Hybrid Tea Roses to 6-8" tall, Knockout Roses to 12" tall
- Hydrangeas - Mop-head and Endless Summer types to 6-12" tall
Hold off on pruning crape myrtle until at least mid-April. Sudden cold blasts could kill crape myrtle if pruned this early. Wait to see what comes out this spring. After a hard winter, they may die back to the ground. But don't give up...they may sprout from the roots as late as mid-May.
