• Prune all roses except those that bloom once a year.
• Plant bare-root roses.
• If desired, apply pre-emergent weed killer.

• Clean up all debris.

February

• Finish pruning by mid-month since the sap will begin to rise and the roses will try to put out new growth.
• Also finish planting.
• Do not apply dormant spray once the bushes begin to leaf out since the spray will burn the tender growth.
