Top 6 Tips for Rose Gardening and How to Deal with Rose Diseases?

To make sure your precious roses stay in the best health, simply follow these tips.

1. Black spots on the leaves

This disease is commonly known as a black spot. The black spots appear as circular with borders with fringes on the leaves. They make the leaves turn yellow. Remove the infected foliage and collect the fallen leaves around the rose. Artificial sprays can be used to prevent or treat this type of rose disease.

2. Battered or malformed young batons.

Known as powdery mildew, this is a fungal disease that covers the leaves, stems, and buds with white dust scattered by the wind. It causes the leaves to curl and turn purple. Spray with Funginex or Benomyl to treat this fungal disease.

3. The blistered lower part of the leaves.

Known as rust, this disease is characterized by orange-red blisters that turn black in the fall. It can survive the winter and then attack new shoots in the spring. Collect and dispose of leaves that are infected in the fall. A spray of Benomyl or Funginex every 7-10 days can help.

4. Malformed or atrophied leaves and flowers.

This is caused by mites. They are small yellow, red or green spiders found at the bottom of the leaves where they suck the juices. The application of Orthene or Isotox can help in the treatment of this infestation.

5. Weak and speckled leaves with tiny white nets under them.

This is caused by aphids. They are small, soft-bodied insects that are usually brown, green or red in color. Often grouped under leaves and flower buds, they suck the plant juices from the young buds. Malathion or diazinon spray can help roses survive these insects.

6. Flowers that do not open or deform when they open.

Thrips could be the reason behind this problem. They are thin insects, yellowish brown, with fringed wings that also suck the juices of the floral buds. Cut and discard the infested flowers. Orthene and malathion can also treat this problem.

Remember that roses are hungry eaters that require a lot of fertilizer to become healthy shrubs.
