What to do if ivy has worms, ivy has worms, what should I do

1. Prune.

After the ivy grows worms, it can be pruned. Use sharp scissors to cut off the branches and leaves of the plant that have suffered from serious insect infestation, so as not to affect the growth of other healthy branches and leaves, and apply carbendazim solution or plant ash to the wound after pruning to help the wound heal as soon as possible.

2. Apply alcohol.

When ivy grows insects, you can also apply alcohol to the branches and leaves. First of all, you need to buy high-concentration alcohol or liquor from the market, dilute it with water at a ratio of 1:10, and then use a cotton ball or cotton swab to dip the dilution solution and apply it to the area of ivy that is infested.

3. Spray the agent.

After ivy grows insects, it can also be sprayed on the plant. First of all, you need to buy special insecticides from the market, such as deltamethrin, dimethoate oxide and other agents, and then according to the dosage on the package, mix it with water evenly, spray it on the leaves of the plant, spray it every other week, and three times in a row can completely eliminate the pest.

4. Ventilation.

Ivy grows in a poorly ventilated environment, there will be a phenomenon of insects, so in the later maintenance process, it is necessary to regularly ventilate the ivy to maintain air circulation in the environment, and you can also bury quicklime in the soil where the ivy is planted to avoid pests from approaching the plant.

Ivy insect pests are more serious in the form of leaf roller borer, scale insects and oysters, and different insect pests have different methods

Scale insects. Common pests. The affected plants grow poorly, and can be polluted with soot disease, causing yellowing of leaves and early defoliation. [7]

Prevention and control method: manual scraping. When the occurrence area is large, it can also be sprayed with 40% oxidized dimethoate emulsifiable vitex 800 times.

Abysmal oysters.

1) Pest characteristics: nymphs and female adults suck the sap of branches and leaves. In severe cases, it is covered with leaves and branches, causing the plant to dry up, yellow, and die.

2) Prevention and control methods: combined with shaping, cutting insect branches and leaves in winter, and concentrated burning. During the hatching period of nymphs, spray 1000 times of 50% phoxanthion or 1500 times of rapid culling.

In the prevention and control of aphids, various means should be used to stop their harmful activities, mainly the following points:

First, the elimination of aphids, to start from the overwintering period of flowers, can get twice the result with half the effort, such as simply relying on the most serious aphid damage in spring and autumn, the control effect is not significant.

2. Newly introduced flower species and seedlings should be strictly inspected to prevent the invasion of new pests from other places, and the soil and old flower pots should be disinfected to kill the residual insect eggs.

3. Combined with pruning, the residual flowers, diseased branches and leaves that have inhabited or lurked by aphids or insect eggs should be completely removed and burned in a centralized manner.

Fourth, the varieties of flowers are different, their insect resistance is also different, should be selected resistant to diseases and insects, not only to reduce the harm of aphids but also to save the cost of drugs.

5. When a small number of aphids are found, you can use a brush dipped in water to brush them, or put the potted flowers under tap water to rotate and rinse, which not only kills the aphids, but also washes the leaves, improves the ornamental value and promotes foliar respiration; If conditions permit, natural enemies such as ladybugs and lacewings can also be used for prevention and control.

6. When a large number of aphids are found, they should be isolated in time, and drugs or soil methods should be used immediately to eliminate insect pests, and the specific measures are as follows: 1. Prepare tobacco leaf water with a ratio of 1:15 and spray it after soaking for 4 hours.

2. Spray with a ratio of 1:4:400 to prepare a solution of washing powder, urea and water.

3. Spray with 10% dimethoate emulsion 1000 times or malasulfur emulsion 1000 to 1500 times or dichlorvos emulsifiable concentrate 1000 times.

4. For aphids such as peach powder aphid, which are covered with wax powder, 1 neutral soapy water or washing powder should be added when applying any agent.

1. Artificial aphid prevention method: In the early stage of aphid occurrence, artificial aphid prevention is adopted, and the aphid is brushed off with a brush and buried in the potting soil.

2. Plant repellent aphid method: the smell of leeks has a role in repelling aphids, and planting them with flowers can reduce the number and harm of aphids.

Pepper anti-aphid method: use 50 grams of fresh chili pepper or dried red pepper, add 30 to 50 grams of water, boil for about half an hour, and spray the infested plants with its filtrate to have special effects.

4. Washing powder anti-aphid method: 3 to 4 grams of washing powder, 100 grams of water, stirring into a solution, spraying 2 to 3 times continuously, the control effect is 100%. Reed should be used as a washing powder.

The cultivation method of ivy is relatively simple, and it uses nutrient soil mixed with humus, garden soil and coarse sand to ensure the growth nutrients it needs to grow. It prefers a moist environment, so water it every 2-3 days. Apply more nitrogen fertilizer and less phosphorus and potassium fertilizer daily.

And ivy prefers a warm environment, so you can't leave it outside in winter to prevent freezing to death.

Flower soil selection. Ivy is more resistant to barrennessPrefers acidic, loose, fertile sandy soils。If you mix your own soil, you can put humus soil, plant ash, and fine sand soil according to 2:

Formulated in a 1:2 ratio. Prepare some after preparationCoarse cinders or fine tiles, spread at the bottom of the pot to ensure the water permeability and breathability of the pot.

Light temperature. Ivy is resistant to humid environmentsIt can grow in a low-light environment。We can place it in a dark toilet, bathroom, etc., but it should be exposed to sunlight at the right time.

If you don't see sunlight for a long time, the plant will grow and the leaves will lose luster, so it's best to have 4 hours of light a day.

If placed on a balcony and shaded in the summer, the optimum growing temperature is 20-25 degrees Celsius, and in the winter the room temperature should be higher than 5 degrees.

Water and fertilizer requirements. IvyLikes moisture and fertilizer。In summer, you should water frequently, keep the potting soil moist, and observe the potting soil diligently.

If you find it dry, replenish water in timeGenerally, water 1-2 times a week. Spray the surroundings of the plant with a watering can to keep the environment moist.

When fertilizing, apply more nitrogen fertilizer and a small amount of phosphorus and potassium fertilizerIt is better to use bone meal fertilizer or rotten cake water fertilizer. 。If you don't do plastic pruning, the whole plant will lack an ornamental plant type, and the whole plant will have poor air permeability, and eventually the whole plant will die.

When pruning, remove the diseased branches, remove the inward-growing branches, and keep the outward-growing branches. At the same time, when pruning, each branch needs to be cut in a staggered manner, which will make the whole pot more hanging and more ornamental.

Pest management. Ivy is commonPests are scale insects and red spidersIsospinal base. These pests mainly suck the sap from the leaves, and in severe cases, they can cause the whole plant to wilt.

If we find a disease, we can first use artificial deworming, and then spray the whole plant with a phosphorus killing agent.

Ivy is commonDiseases are leaf spot, leaf rot, and blightWait. Most of these diseases start with the leaves and then threaten the whole plant. If the leaves are found to be abnormal, they should be used in time, and carbendazim and methaloxin can be diluted and sprayed.

Repot and change the soil every year

If ivy is to flourish, it is indispensable to repot the soil once a year. usIt can be done every spring, replace one-third of the soil in the pot, add a new configuration of soil, so that the whole plant grows in a sparse cherry blossom and pine fertile soil environment.

Propagation by cuttings. Ivy branches can grow aerial rootsIt can be propagated by cuttings。The remaining branches will be pruned, put in a container of water for rooting treatment, and after the small root system is born, cuttings will be placed in the pot, and a new pot of ivy can be propagated, so that we can raise more and more ivy.
