Preventing Disease- Gardening Rose Tips You Can Use

One of the biggest concerns that rose gardeners express is in regard to preventing disease. Gardening rose bushes seems to require a fair amount of work in general, so gardeners are often truly concerned about the time commitment that will be required to keep their rose bushes healthy. Preventing and treating disease is one of the most important things you can do to ensure healthy roses.

Gardening rose bushes isn’t really all that difficult if you know what to do. Rose gardening simply requires some attention to detail and enough knowledge to know how to avoid most problems and treat others when they occur. Here are some things you can do to prevent rose disease.

Space them properly – Proper spacing helps prevent disease. Gardening rose bushes that will flourish requires allowing air to circulate between the plants. Rose plants are far more susceptible to disease if they don’t get proper air ventilation.

Water them in the morning – Evening watering invites disease. Gardening rose bushes requires morning watering to help ensure that your roses don’t develop powdery mildew – one of the most common rose diseases. Morning watering ensures that the water will have the opportunity to evaporate as the day warms up, while evening watering invites the growth of fungus.

Keep a check on them – It is critical to examine your rose plants regularly so that you can watch out for disease. Gardening rose bushes will be much easier if you can catch disease at the first sign.

Remove diseased branches – As soon as you spot disease branches or leaves, remove them. Removing the diseased branches helps keep the disease from spreading.

Treat the disease- There are many products on the market to treat the most common rose diseases like black spot, powdery mildew and rose mosaic. There are also home remedies that can be just as effective. And, if you’re concerned about protecting the environment by gardening organically, there are plenty of organic alternatives to treating disease in roses.

How do I know if my roses are diseased?

One question many rose gardeners have is about spotting rose diseases. Here are the most common rose diseases and their symptoms so that you can determine which disease you have in order to better prepare to treat it.

Black Spot – The disease is characterized by nearly circular, black spots with fringed margins. Black spot is more common in wet weather and cooler temperatures.

Rust – Rust shows up first on the undersides of the rose leaves – and looks like rust. As it spreads it will also show up on the tops of the leaves. Rust develops in temperatures between 65-75° coupled with moist conditions.

Powdery Mildew – This fungus, which can occur in dry weather as well as wet, causes leaves to have a white, talcum-powder-like growth on them.

Rose Mosaic – Rose mosaic is caused by a virus. Its symptoms include splotches of yellow and green on the rose leaves, often in a mosaic pattern.
