Strong, healthy rose bushes are aromatic and beautiful. They are a source of pleasure for both gardeners and garden visitors. If your rose bushes were undersized, had yellowing leaves, or seemed generally unhealthy last year, there are several steps you can take to bring them back to life this spring.
Uncover rose bushes slowly in the spring. Observe new growth carefully. Take away about one quarter of the mounded soil that provided winter protection when you see one quarter inch of new growth above the mound.
Continue to watch for new growth. Take away about one half of the remaining mounded soil when new growth reaches between half and three quarter inches.
Remove the remaining mounded soil when new growth is about one inch long. Uncovering rose bushes slowly will help to protect them if there is a late freeze.
Prune the rose bushes, cutting long canes to a length of about 10 to 12 inches. Remove any dead flowers and weak canes.
Mulch rose bushes well, using manure which is been well rotted, or peat.
Mix one tbsp. of Murphy's oil soap with two gallons of warm water. Spray rose bushes with this solution every week.
Feed your roses every three weeks. You can make a homemade rose food by mixing two tbsp. ammonia, one cup beer, one tbsp. corn syrup, two tbsp. fish fertilizer, two tbsp. hydrogen peroxide, four tsp. instant tea granules, two tbsp. Murphy's oil soap, one tbsp. unflavored gelatin, two tbsp. whiskey, and two gallons of warm water. Add a few banana peels or rotten bananas to the soil around your roses to make it potassium rich.
Plant parsley and garlic between the rose bushes to keep aphids and other pests away.
