How To Keep Your Roses Disease Free

One of the main problems in growing roses is insects and diseases. Roses are especially susceptible to aphids, although the newer hybrid roses are more resistant than the general garden roses.

The three most usual diseases that roses suffer are rust, powdery mildew and black spot. Knowing how to diagnose your roses and treat them can keep them from dying out.

During cool or wet weather roses may develop powdery mildew. The mildew is around in the air all of the time, but when the weather and temperature meet certain conditions it will attack the plant.

It appears as powdery patches on the roses leaves, but may also be seen on the plants stems. The plant will begine to loose it’s leaves and the buds won’t open to bloom.

Planting your roses where they’ll receive full sun can help deter powdery mildew. You can usually spray the mildew off with a water hose. But, if it’s gotten really serious then you’ll need to prune the infected leaves. Keeping the plant free of infected leaves will keep it from spreading to other parts of the plant.

The weather conditions also produce rust on your roses. Once again, cool and moist days are the culprit! Removing all of the infected sections of the plant is about the only way to get rid of rust.

Another problem with rust is that it continues to thrive in soil and on the leaves that have fallen from an infected plant. If you replant in the same area that an infected plant grew in, then the new plant can also get rust from the soil.

Rust will usually shows up early in the growing season and will appear in bright orange places on the leaves and stalks. After the plant has been infected for awhile, the spots will start to turn black.

Black spot is another disease that often attacks roses. Although this disease occurs under moist conditions much like the others, instead of cool temperatures, black spot develops in warm conditions.

It will appear as a black or sometimes dark brown blotch on the plants leaves and they will begin to turn yellow and soon fall off. If the disease isn’t controlled it will spread and eventually kill the entire plant.

At the first sign of black spot, remove the affected leaves. You need to also remove any leaves that have fallen on the ground. And, spreading a layer of mulch several inces thick around your rose bush can also help prevent the disease.

One effective home remedy for black spot is to mix equal amounts of fat free milk and water. Apply the solution to both sides of the leaves and the stem with a spray bottle. The mixture will actually cause the growth of a fungus that prevents black spot fungus!

There are some precautions that you can take to keep your roses healthy and growing beautifully! Make sure to plant them in a sunny spot so that the leaves and stems can dry quickly after a rain or watering.

Try to water the bases of the plant, taking care not to get the leaves wet. And, always water your plants early in the morning so that they’ll have plenty of time to dry. It’s very important that you begin treatment at the first sign of a problem.

The best way to control insects on your roses is with organic treatments. The less chemicals that you apply, the healthier your plants will be and the better they’ll grow.

One way to naturally treat insect infestations is with other insects! Many insects such as lady bugs will actually pick your plants clean of any so called bad bugs!

A few aphids aren’t a major problem, but they will quickly multiply! Aphids literally suck all of the sap out of the plant and this can be devastating to a younger plant.

They can easily be removed by spraying them off with the water hose. If there’s a large infestation of aphids, you can add a few drops of liquid soap to some water and use it to spray the plants.

Many roses are now disease resistant, read the packaging or talk to a knowledgeable person at your nursery to select the right ones. With a little attention and loving care your roses can be both bug free and fungus free.
