In summer roses should delight with lush flowering, but sometimes instead of new buds gardeners notice yellowed leaves and drying shoots. It is not worth immediately thinking that the bush is dying. Most often the plant simply signals that it lacks correct care. The main thing is to determine the cause in time and help the rose recover.

Lack of moisture and strong heat

During prolonged heat the soil quickly dries out, and the roots do not have time to receive a sufficient amount of water. First of all the lower leaves begin to yellow, then they dry and fall off.

Water the roses rarely, but abundantly, so that the water soaks the soil to the depth of the roots. After watering it is useful to mulch the earth — this will help preserve moisture and protect the root system from overheating.

Lack of nutrition

By the state of the leaves one can understand which elements the plant lacks.

The leaves become light-yellow completely — possible lack of nitrogen. Yellowness appears between the green veins — the rose lacks iron or magnesium. The edges of the leaves turn brown and dry — often this is a sign of potassium deficit.

In the second half of summer it is better to refuse nitrogen feedings and make an emphasis on potassium-phosphorus fertilizers. They strengthen the bush and help it flower longer.

Fungal diseases

If on the leaves first dark or brown spots appear, and then they yellow and fall off, most likely the rose is affected by a fungal infection. Especially quickly diseases spread in rainy weather and with poor ventilation of the bush.

Remove all the affected leaves, not leaving them under the bush, after which treat the plant with a suitable fungicide. It is also desirable to thin out too dense shoots.

Pests

Aphids, spider mites and thrips feed on the juice of the plant. Because of this the leaves gradually lose the saturated colour, curl, yellow and dry.

Regularly examine the reverse side of the leaves. The earlier the pests are noticed, the easier it will be to get rid of them without serious damage to the rose.

Mistakes in watering

Not only lack of water is dangerous for roses. Constantly wet soil leads to rotting of the roots, because of which the leaves begin to yellow even with good care.

Water the bush only when the upper layer of the earth has already slightly dried. Try not to pour water on the leaves, especially in the evening.

How to quickly help the rose

If the leaves have begun to yellow, one needs to act at once.

• Remove dry and damaged leaves.
• Check the moisture of the soil.
• Carry out feeding depending on the state of the plant.
• At signs of diseases treat the bush with a fungicide.
• At discovery of pests use suitable means of protection.

Roses rarely yellow without a cause. Usually it is enough to correct the care in time so that already in a few weeks the bush again begins to actively put out new shoots and delights with bright flowering until autumn itself.
