The rose bought not only has yellow leaves but also has worms.

Just bought the rose, has not yet flowered began to yellow leaves, but also insects, leaves a black, a yellow, very sad. Let's listen to Huahua Barabara to pay attention to several aspects of maintaining the rose.

Reason

Excessive fertilization

Rose flowers like fertilizer, fertilization should use light fertilizer water, remember not to excessive, otherwise it will cause fertilizer damage, leaves turn yellow.

Solution: therefore, fertilization should be mainly organic fertilizer, generally diluted more than 500 times, and then poured into the basin soil, do not use immature organic fertilizer and high concentration of chemical fertilizer, because it will burn the roots of rose, leading to wilting and yellow leaves.

Overwatering

Just bought the rose, the young leaves turned yellow, no luster, even the branches will become yellowish green, the old leaves have not changed, the new growth is also abnormal, this is the performance of watering too much, if not treated in time, not only easy to rot roots, but also easy to infect other bacteria, causing the whole plant to die.

Solution:

Remove the rose from the basin immediately and put it in a cool and ventilated place. You can use a hair dryer to blow the cold air, and the soil will be put on the basin after it is dried. Be sure to pay attention to it in the future, watering thoroughly until the bottom of the basin comes out. Next time, you must pay attention to watering until the basin soil is dry.

Matters needing attention in rose maintenance

Rose planted in the ground

In general, there are various types of roses, such as large flower rose, vine rose, miniature rose, abundant rose, ground cover rose and so on.

Ground rose generally needs to be pruned in winter, usually cut off dry branches, diseased branches, dense branches, and must be supplemented with fertilizer after pruning, and chemical fertilizer must not be used. It is best to apply fertilizer after pruning for a week, so that the plant can recover itself for a period of time. The continuous supply of nutrients can make the rose sprout more and bloom more.

A comprehensive pest control should be carried out when the buds of the rose are sprouting. Broad-spectrum fungicides such as stone-sulfur mixture or carbendazim can be selected to sterilize the whole plant and even on the ground. Then, after spitting green leaves of the rose, timely control the harm of prickly sucking pests such as aphids and red spiders.

Potted rose

Refers to potted rose, balcony rose and commercial potted flowers, most of which are cultivated large flower varieties and miniature rose.

When the climate is stable, fertilizer and water irrigation should be strengthened in the north after the Qingming Festival. Fertilizer and water should be applied twice a week for three consecutive weeks to ensure adequate nutrition for the growth and development of rose flowers. Pest control should be carried out in time, especially for aphids and red spiders.

If it is found that the growth of the basin plant is too weak, the pot or soil consolidation should be changed in time, and ignoring it will affect the growth and even death of the rose.

Rose seedling planting

The cultivated land should be cultivated without basic fertilizer, weeds and disinfection.

The planted rose seedlings should be pruned and root-trimmed, and should not be planted without variety, pruning or sterilization.

We should do a good job in irrigation and watering to ensure adequate water sources; we should not plant hastily, watering is impermeable, and everything will be all right if we water it once or twice.

A year's plan starts with spring. In short, the maintenance and management of rose should be carefully protected from the details of pruning, fertilization, watering, disease prevention and other links from the beginning of spring, which will certainly meet our expectations. Rose blooming will bring us a beautiful spring.
