The Q&A Archives: Yellow Leaves on Baby Rose

Question: I have a rose bush planted in a large pot. Almost every spring it comes out real pretty with lots of leaves and covered in blooms. About this time of the year the leaves start turning yellow and fall off. The blooms seems to slow down also. Why does this happen?

Answer: It sounds as though your baby rose is hungry. Roses are heavy feeders. To keep them growing vigorously, an organized program should be followed. Water rose bed thoroughly before and after food has been applied.

January thru February -- As the weather and ground warm up, around mid to late February, organic fertilizers may be applied. Give each large bush one to two cups of a mixture of alfalfa meal, cottonseed meal, fish meal and blood meal, scratch in lightly and water in well. (Smaller roses can use about one cup.)

March thru May -- The initial feeding should be chemical, either liquid or dry. It is applied when spring pruning is completed. Carl Pool, Green Light, Miracle-Gro, Peters or Rapid-Gro are all good soluble fertilizers. Give each Hybrid Tea or other large bush, one tablespoon of fertilizer dissolved in a gallon of water.
For miniatures use one teaspoon of liquid food per gallon of water. Give each plant about a quart. Dry rose fertilizer can be applied in place of liquid. Use according to directions. Liquid feeding in this period should be once a month.

June thru August -- With the introduction of timed release fertilizers, a summer long feeding in one application is possible. These fertilizers are formulated to feed continuously for three to six months in our climate. Feed each average sized bush at least three or four ounces, working it lightly into the soil. Water thoroughly. If you don't care to use this type of product, continue feeding with a water soluble food (twice a month), or a monthly application of dry food. As the weather becomes hot, you may want to switch to soluble fertilizers as they are more readily available to the plants. Iron chlorosis occurs at this time; Sprint 330 can correct this deficiency.

September thru October -- With the advent of cooler weather and rain, your roses will begin their heavy fall blooming season. Once you have done your light fall pruning, you can apply a cup of organic rose food per bush and follow this two weeks later with a liquid feeding. Don't feed with either liquid or dry foods after the beginning of October.

Hope this information is helpful!
