This can be done in spring after first bloom is complete. Pruning of these roses should be confined to shaping of the plant, removal of damaged branches and judicious trimming back to encourage growth. Most shrub roses will naturally obtain a rounded shrub shape without pruning. Shrub and Antique roses require much less pruning. The finest blooms on climbers appear on canes that were produced the previous year. After that time, remove old canes to encourage new canes to arise from the bottom of the plant. They need time to grow long canes for flower production. The leaves will be different, so it's easy to identify them.Ĭlimbing roses should not be pruned for the first two years. Remove sucker growth below the graft union and those sprouting from the roots.Use sharp pruning shears to make sure cuts are clean, not ragged.Make your cuts at a 45 degree angle, about 1/4 inch above a bud that is facing toward the outside of the plant.Prune to open the center of the plant to light and air circulation.Remove canes that are spindly and smaller in diameter than the size of a pencil.Remove canes that are damaged and one of two canes which may be rubbing one another.Remove 1/3 to 2/3 of the plant to stimulate new growth and flower production.Prune Hybrid Tea, Floribunda and Grandiflora roses 3 to 4 weeks before the average date of the last killing frost in your area. Always keep dry fertilizers away from the canes to prevent burning. As a general rule, apply dry fertilizers (non-foliar-feed) on the soil between the trunk and the drip line (end of the branches).Stop feeding in late summer to enable tender new growth to mature before winter.Frequency depends on the type of fertilizer used. Additional light feedings can be applied throughout the growing season to encourage growth and flowering. Fertilize roses in early spring once the chance of frost has passed and just before new growth begins.Be sure your roses are well watered prior to application of fertilizer.Drip irrigation systems and soaker hoses are a great way to effectively water roses while conserving water, reducing your water bill, and promoting disease free plants.At this time of the year, some plants exhibit minor wilting in the afternoon that is natural as long as rigor is regained by morning. In the hot summer months, roses need water only when they show signs of stress in the morning, which is expressed as curled or drooping leaves and branches.Check plants often and be sure to wet the soil thoroughly until the entire root ball is saturated and water runs from the drainage holes. Be sure that all pots have drainage holes to prevent overwatering. Roses growing in patio containers usually require more frequent watering than plants in the ground.Avoid wetting foliage, especially in the evening, to reduce disease problems. Water plants early in the day to minimize water loss due to evaporation. Frequent light watering encourages a shallow root system that is not as prepared to handle the rigors of prolonged drought. Too much watering wastes water and pushes nutrients away from the plant roots which can lead to excessive weeding, fertilizing and pruning.
