Leaves of a rose in a hole - what to do with the problem
Content:
Roses are popular but moody plants. Taking care of them is a real art. Having no idea what to do if holes appear on the leaves of the rose, you need to consult with experienced gardeners. Most likely, the point is in the infection of the plant with pests, the fight against which is worth learning in more detail.
A rose has leaves in a hole - is it normal or not
Roses have a complex leaf structure. In total, there are from 5 to 7 of them on the stem, but there are roses with a large number of leaves, in some species there are 12-15 of them. The variety also affects the surface quality of the green part of the plant. Leaves can be dull, glossy, wrinkled, high or low gloss. The color scheme is no less varied - from light green to bronze.
Aphid covered rose leaves
If the leaf has changed its structure, was light and darkened, shrunk, holes or specks appeared on it, it's time to think about treating the plant with fungicides or insecticides. Black specks and holes cannot form without reason. This is a sign of a disease or pest attack on the bush.
Why is this happening, the causes of the problem
The holes in the leaves are the merit of aphids, scale insects and other parasitic insects that migrated to a bush weakened due to lack of proper care. Sometimes several types of pests settle on roses at the same time. You need to know in detail about the method of destroying each of them, especially if there is a real rose garden in the garden.
Aphid
This small, fast-breeding insect settles on young shoots and unopened buds. A plant eaten by aphids becomes easy prey for other pests, cannot resist diseases provoked by viruses and bacteria, and dies.
The pests ate the plant
Huge colonies of aphids live on the bush. You can find them on the inside of the leaves, the peduncle and inside the bud. Females do not have wings, they are not so dangerous. But the larvae laid by them eat huge holes in the greenery, feed a lot and constantly, become capable of reproduction already on the 10th day of life.
Spider mite
Few gardeners manage to notice a spider mite on plantings at the time of its appearance. This small arthropod pest has an almost transparent body, colored greenish-yellow. This color allows the tick to remain invisible not only to humans, but also to other insects and birds.
Ticks feed on plant juices, preferring young shoots to old ones. They reproduce throughout the summer and are capable of causing serious damage to green spaces, eating them. Deprived of the life-giving forces they need, the leaves curl, become covered with a network of small holes. Nothing can be done, you will have to cut off or destroy the entire plant.

Leaf roll
Insect from the family of butterflies with bristly or finely ciliated antennae (males). Extremely nondescript, but very harmful to plants. With the onset of autumn, the leafworm lays many eggs.In spring, yellowish-brown caterpillars hatch from them. They feed on the buds and leaves of roses, which is why they curl up into a tube and become covered with small holes.
A small number of tracks are disposed of manually. If there are many of them, the bushes are treated with special preparations, not allowing the caterpillars to turn into butterflies and lay eggs again.
Shield
One of the most dangerous pests in the garden, belongs to the family of worms. The insect is small, it is difficult to spot single specimens. Scabbards cover the leaves with a sticky bloom. In fact, it is not they themselves that are dangerous, but this raid. Deprived of oxygen, green leaves of plants become vulnerable to viruses and bacteria.
To get rid of the pest, you have to work hard. Chemical preparations or folk remedies almost do not act on a harmful insect. Spraying won't help.
The gardener will have to take a soft cloth or sponge, soak it in soapy water, and use it to wipe each leaf. If there is only one rose in the garden, then this will not cause problems, but it will be difficult to cope with the infection of the rose garden with scabbards.

Rose cicadas
The insect is able to fly from plant to plant. He has an elongated body and yellowish-green wings. Pests gnaw the leaves, and the larvae laid by them feed on the plant sap, which leads to its yellowing and wilting.
Finding the rose leafhopper on the leaves is simple. They become covered with yellowish-white spots and holes. There is no effective method of pest control. The infected parts of the plant are destroyed, the rest are treated with various preparations poisoning the leafhopper and its larvae.
What to do in this situation, what can be processed from chemicals
Each gardener has his own tricks to help him protect plants from pest attacks. Some use exclusively purchased drugs, others trust folk remedies more. But the origin of a substance capable of destroying, for example, a spider mite is not so important, the main thing is the achieved effect.
