Best After-Pruning Rose Fertilizer

Best KnockOut-rose Fertilizer


  • Question: What should I feed my climbing rose?

Answer: Most rose types have a strong appetite, so feed them in the spring and again in June or July with a powder or granular rose fertilizer.

  • Question: When should I fertilize my climbing roses?

Answer: Fertilize after trimming in the early spring, around four weeks before spring growth begins. Stop fertilizing six weeks before the first expected frost in cold-winter locations to enable the plant to become dormant before a harsh freeze.

  • Question: Is bone meal good for climbing roses?

Answer: One of the most popular suggestions for planting roses is to “toss a cup of bone meal in the bottom of the hole.” The logic for this is that bone meal is phosphate, which roses require, and it’s preferable to place it in the hole since it doesn’t go through the soil rapidly.

  • Question: Why does my Climbing Roses have flowers but no leaves?

Answer: It might be a question of patience or an indication of water or nutritional stress if your Climbing Roses aren’t developing leaves. Climbing Roses plants, like other succulents, can go into a pre-dormancy or pseudo (false) dormancy if they are water or nutrient, challenged, in which case they will cease flowering and start shedding leaves.
