Pay attention to the warm and cold-resistant culture of ivy

Ivy, as a plant farmed by many people, naturally has its advantages. Ivy is green in color and beautiful in appearance. It can purify the air and is good for the body. However, the breeding of ivy is not particularly simple, ivy likes to be warm and not cold-resistant, so we should pay more attention to it when breeding. Next, let the editor introduce the breeding methods and matters needing attention of ivy.

The culture method of ivy:

1. Cuttage propagation

Ivy is mainly propagated by cuttings. Pay attention to: cuttings can not use perennial old branches, but to choose strong-growing twigs; pay attention to protect the bud points on the cuttings, otherwise it will affect the survival of new plants.

2. The temperature should be suitable.

Ivy likes warmth, and the suitable temperature for growth is 20 ℃-25 ℃. It is afraid of heat and is not resistant to cold. Therefore, when placed in indoor maintenance, we should pay attention to ventilation and cooling in summer, and the room temperature in winter should be kept above IO-C, and the lowest should not be less than 5 ℃.

3. Moderate lighting

Ivy is light-loving and shade-tolerant. Under semi-light conditions, the internodes are shorter, the leaf shape is the same, and the leaf color is bright, so it is appropriate to culture in a bright indoor light. If you can put outdoor shade for a period of time in spring and autumn, so that you can see more sunshine in the morning and evening, then the vitality will be exuberant and the leaves will be green. However, we should pay attention to prevent the direct light, otherwise it is easy to cause sunburn.

4. Watering should be moderate.

Watering in the growing season should be dry and wet, and the basin soil should not be too wet, otherwise it is easy to cause rotten roots and fallen leaves. The room temperature is low in winter, especially to control watering and keep the basin soil slightly wet. The northern winter climate is dry, it is best to spray Duchuan once a week with water close to room temperature, in order to maintain air humidity, the plant appears alive, the leaf color is green and shiny.

5. Fertilization should be reasonable.

In order to cultivate ivy in the family, the basin soil should be composed of Sichuan rotten leaves or charcoal soil mixed with river sand and a small amount of bone powder, and thin pancake fertilizer and water should be applied once every 2-3 weeks in the growing season. Do not apply fertilizer in summer and winter. Do not apply nitrogen fertilizer when fertilizing, otherwise, the patterns and patches on the leaves of mosaic varieties will fade to green. The ratio of nitrogen, phosphorus and potassium should be 1%, 1%, 1%, 1% and 1%, respectively. During the peak growing season, the leaves are sprayed with 0.2% potassium dihydrogen phosphate once or twice, which will make the leaves look more beautiful. However, attention should be paid to avoid contaminating the leaves when applying liquid fertilizer, so as not to cause the leaves to scorch.

6. Cut it in time

When the ivy grows to a certain height, you should pay attention to picking the heart in time, which can promote its multi-branching and make the plant plump.

Diseases of ivy and their solutions:

The main diseases are algal leaf spot, anthracnose, bacterial leaf rot, leaf spot, root rot, blight and so on. The damage of leaf roller borer, shell worm and red spider is more serious.

Solution to the disease of ivy:

1. Remove dead branches and leaves in late autumn or early spring and cut off diseased branches and leaves in time and burn them.

2. Spray 65% Dysen zinc 600 times solution before the disease to protect.

3. Reasonable fertilization and watering, pay attention to ventilation and light transmission

4. Spray 50% carbendazim or 50% thiophanate 500-600 times, or 75% chlorothalonil 600-800 times at the initial stage of the disease.

5. After the onset of the disease, spray 97% rust sodium 250,300 times (add 0.1% washing powder), or 25% trimethoprim 1500-2500 times.

The above is the introduction of the ivy culture methods and points for attention, have you learned? Ivy is one of the common potted green plants in the home, breeding plants must be careful in order to let it be protected and grow healthily.
