In January and February, roses in the ground or containers benefit from pruning and other care that readies them for a fabulous first bloom in April. Here are some planting and care tips from the San Diego Rose Society:
- Renew roses by pruning established plants. Complete pruning of floribundas, shrubs and miniatures early in the year. Prune hybrid teas and climbers by Valentine’s Day.
- After pruning established roses, apply organic rose food and then a 3-inch layer of mulch to prevent weeds.
- Start feeding established roses when there are 6 inches of new growth.
- Avoid pesticides that harm beneficial insects that fight harmful pests.
- Control aphids by washing them off with a strong stream of water or flicking them off with your fingers.
- Rose slugs thrive on the underside of a leaf and eat most of it, leaving only lacy-looking remains. Control them with Spinosad, an organic product.
