Rose is the queen of flowers. It is gorgeous and wonderful but is one of weakest plants, too. Rose is always damaged by diseases and pests. And if you have rose in your garden, here is the information you should know.
Common rose diseases vary by area, as the fungi which cause many of them are affected by temperature and moisture. Some of the most common rose diseases are Black Spot Disease, Powdery Mildew, Rust, and Rose Mosaic.
While rose diseases do not always kill rose plants, they often affect the leaves and make it more difficult for the rose to survive in the winter. Step-by-step sowing instructions:
This disease, as its name implies, appears as black spots on the upper surfaces of the rose’s leaves. It is caused by a fungus, which is allowed to propagate in moisture, which can come from rain or watering over the leaves instead of down at the soil. It can also be caught from other diseased plants, as the fungus can spread through fallen leaves, or even through composting of diseased leaves and stems. It causes most diseased leaves to drop off early, but survives through the winter on any leaves that manage to stay on the rose. It can also survive through the winter on the stem.
This disease is not harmful at low levels, merely causing small orange growths on the underside of leaves. At higher levels, leaves begin to be damaged, which can damage the plant since the leaves are the part of the plant that produces energy.
This disease is different from other common rose diseases, as Powdery Mildew does not need water. This growth, which resembles a white powder, occurs on the top and bottoms of leaves and on stems. In the summer, if roses are free of any fungi caused disease, Powdery Mildew can simply be hosed off of affected roses and thus, can be easy to take care of.
This viral disease does not kill plants. Many rose gardeners do not need to deal with this disease, as all it does it cause splotches, often yellow and green, to appear on leaves.
There are many other rose diseases, and which ones are the most common in each area changes depending on the weather in that area. Ask for free gardening advice from neighbors, friends, and fellow rose growers, or pick up one of the many books available on growing roses.
Once a plant is diseased, there are many gardening tips available as to how to deal with these. An easy gardening tip is simply to prune away the affected areas.
These common rose diseases should not be too much of a gardening problem for any rose gardener, as, with early detection, they can easily be destroyed without the death of the entire rose bush and garden.
