Apply this amount at one time. Sandy soils will require more frequent watering. Overhead watering is desirable in early spring before growth starts. This watering will prevent the canes from drying. After growth has begun, apply the water directly to the soil or water early enough in the day so the foliage will dry before evening.
Wet foliage is susceptible to diseases.
Fertilizing Applying well-rotted barnyard manure to rose beds in early spring is one of the best methods of fertilizing roses. This rotted manure adds both nutrients and organic matter to the soil. Dehydrated manure, bonemeal, and soybean meal also are good fertilizers. Because these materials decompose slowly, you should supplement them with an all purpose fertilizer or with one of the many available rose fertilizers. Keep all manure and fertilizers at least six inches from the canes.
