Pruning Use bypass pruners that work similar to scissors. Anvil-type pruners will crush your rose stems.
Remove all the old mulch and dead leaves and throw them in the trash, not your compost pile. Dead leaves can often have mildew spores and other diseases on them that can infest your compost pile and create problems later on.
1. Apply both a pesticide and a fungicide to your pruned roses and the ground around the plants. Fungus spores such as mildew can live through the winter in your soil.
2. Seal pruned canes larger than a pencil with carpenter’s glue (it’s waterproof) to protect against cane borers.
3. Re-potting: Check your roses in pots to see if they need to be repotted. How low is the soil in the pot? If it is lower than 3 inches below the rim, it is probable that the soil has become too compacted and the tiny hair roots can’t get the oxygen they need. Lift the entire plant out of the pot, loosen any soil around the root ball and repot in fresh potting soil.
Water and Feed
1. Do not fertilize your roses until mid-February.
2. Continue to water your ground-planted roses, once or twice a week depending on the daytime temperatures. Be sure you are deep watering to a depth of 18 to 24 inches.
3. Roses in pots typically need to be watered more often than roses in the ground, approximately providing them with a deep watering every 4 days.
