Rust is one of the most harmful and insidious diseases of roses . Fighting it is almost impossible and comes down to pruning or removing plants. The only way to productively treat roses is timely prevention and prevention of the development of this dangerous disease. And start your prevention even with planting planning, buying seedlings and choosing a place to grow.
When choosing plants for planting, always inspect them carefully and purchase only strong healthy roses . Do not buy plants in the markets, contact specialized stores or representative offices of rose garden nurseries – places where you can get expert advice. It is better not to buy seedlings in a completely closed package, you should at least see the surface of the shoots (and ideally the roots). Never buy roses with less than two or three strong trunks and a developed, powerful, spreading rhizome. If you are in doubt about the characteristics of the plant, try to buy seedlings later, when they already have leaves.
When choosing a planting site, immediately exclude swampy, damp, compacted, heavy and overly acidic soils. Roses will not be able to grow healthy in soil with a low content of nutrients, including potassium. Therefore, the soil for planting them choose fertile and light enough. The site chosen should be free to circulate air, so the site should be well ventilated, but devoid of drafts and not angular with its sharp blows of strong gusty winds. The place of growth should not be too hot – avoid areas where the sun illuminates the plant at the zenith of its activity.
Proper care of growing roses is the key to their health and resistance to pests and diseases. It is necessary to water rose bushes very carefully, without splashing foliage and stems with jets and drops. Try to direct a slowly flowing stream of water directly under the root. A watering can is best for watering, but if you cannot water low enough with it, a hose and a simple container will do. It is desirable that the water for watering roses is not too cold and matches the ambient temperature. Do not leave the bushes wet even after heavy rainfall – immediately shake off the moisture from the flowers and leaves, as dampness contributes to the development of fungal diseases. Cut regularlywilted flowers and twigs, not only preventing the formation of a favorable environment for fungi, but also stimulating the growth and further flowering of the plant. No less carefully pick up petals and leaves that have fallen to the ground. It is better not to use them for compost, because it is often under the fallen leaves that fungal spores gather. Try to regularly feed roses with potassium containing special complex fertilizers for roses.
A necessary measure of natural rust prevention is also a regular (at least once a week) examination of roses for traces of damage by other pests – aphids or worms . It is on plants infected with these insects that real rust usually appears. If you find aphids, immediately crush them with your fingers and spray the rose bush with soapy water.
