What if the leaves of potted tulips turn yellow? the solution of losing leaves in potted tulips

Although most of the tulips we know exist in the form of flower fields, of course, the situation of people who love tulips can not be avoided. With the increase in the number of people who like tulips, potted tulips have gradually entered thousands of households. However, not everyone has mastered the techniques and methods of tulip planting, so there will inevitably be some problems in the process of planting.

What if the leaves of potted tulips turn yellow?

1. Pest control and ramet transplanting

Clean the withered leaves in time to make sure you have no dead leaves on the ground.

Diseases and insect pests are mainly fungal infections should be sterilized with disinfectant, or diluted pesticides should be directly sprayed.

If the plant is too dense, it is necessary to split and transplant to ensure that there is a certain gap between the plants and good ventilation. If it is potted, try to move it to a ventilated place for maintenance.

2. Fertilizing and watering, reasonable temperature control

If the soil is too dry or too waterlogged, the plants will be morbid, so it is necessary to water them reasonably, dry and wet. Tulips in the garden can not be irrigated on a large scale and sprayed as far as possible.

Liquid fertilizer is the main fertilizer. The application of dilute liquid fertilizer once a week can appropriately increase phosphate fertilizer during the yellowing of leaves.

When the temperature is more than 20 ℃, water can be sprinkled around the plant to cool down.

The solution to the loss of leaves in potted tulips

1. Virus disease

There are many kinds of viruses that harm tulips, including mosaic virus and broken color virus.

Mosaic virus causes yellow stripes or fine-grained spots on the damaged leaves, dark spots on the petals, and serious leaf decay, so we should pay attention to timely prevention and control of aphids and weeds.

The broken color virus causes yellowish or grayish white stripes or irregular spots on diseased leaves, sometimes forming flowers and leaves, light yellow or white stripes or irregular spots on petals, and broken flowers on red or purple varieties. Its prevention and control method is the same as the general virus disease, but the planting place should be far away from the lily.

2. Lighting problem

Tulips on the pot after more than half a month, should be properly shaded, in order to facilitate the growth of new roots.

Sufficient light is necessary for the growth of tulips. Insufficient light will cause poor plant growth, cause sprouting, plant weakness, lighter leaf color and shorter flowering period.

3. Fertilization

Tulips prefer fertilizer and should be fully fertilized before planting. Generally, dry chicken manure or rotten compost is used as base fertilizer and fully irrigated, and carefully ploughed and raked 2-3 days before planting to ensure that the soil is loose. After two leaves, liquid fertilizer can be applied 1-2 times, compound fertilizer with balanced nitrogen, phosphorus and potassium should be applied 3-4 times a month in peak growing season, fertilizer should be stopped at flowering stage, and liquid fertilizer of 1-2 potassium dihydrogen phosphate or compound fertilizer should be applied after anthesis.

4. Soil problems

Sandy loam soil is better for tulip culture, neutral alkali is better for soil acidity and alkalinity, acid soil can not be used.

5. Watering problem

Excessive irrigation should be avoided in the process of tulip cultivation, but more water should be needed within a week after planting, and the water demand should be reduced after germination, especially during flowering. Watering should be done "a small amount for many times" if it is too dry. Growth will be significantly delayed, and the air humidity should be kept at about 80 φ during the growth period of tulips.

What if the tulip bulb is rotten?

1. Tulip bulbs are dug up early

The bulbs of tulips were dug up earlier, and the growth of new bulbs was not full. In order to improve the quiet quality of the newborn forest, the light must be sufficient during the flowering period of the plant, and the available fertilizer based on phosphorus and potassium fertilizer should be applied, and the plant bulb should be dug up before the leaves turn yellow.

2. the storage temperature of tulip bulb is high.

When storing bulbs, you should not keep the temperature too high and the humidity too high. The suitable storage temperature is about 15-20 ℃, and it is placed in a well-ventilated place indoors. If the indoor temperature is too high, humidity jump and poor ventilation, it is easy to cause pathological changes and decay of the bulb.

3. The tulip bulb is too wet

New bulbs with germs in the soil or not dry can cause the bulbs to rot. After digging, the original soil brought before electricity should be put in a cool and ventilated place to wait for the bulb to dry, and then graded into paper bags or on ventilated shelves for storage and maintenance.

4. The soil of tulip bulb is sticky.

When planting, we should keep the soil stickiness not too strong, and use soil with good drainage. Pay attention to drainage during cultivation, usually watering should not be too much, should keep the planting layer moist, and often loosen the soil, so that the soil ventilation is good.

What if the tulips don't sprout?

1. Disinfection

If you want tulips to germinate, it is important to choose a good bulb, and then disinfect the bulb. Before planting, this step of disinfection is essential. The disinfectant can be soaked in formalin for about half an hour. After it is taken out, it needs to be dried before planting.

2. Soil selection

The second is to plant the bulb in the fertile sandy soil, to note that the soil layer must be thick, the soil permeability must be good, and pay attention to the soil temperature when planting tulips, which is generally planted below 12 degrees Celsius, which is most conducive to germination.

3. Fertilization

After planting, you should also apply the right amount of fertilizer, so that there is enough nutrition to promote the germination of tulips. Fertilizers can choose livestock manure or other phosphorus and potassium fertilizers. When the young buds of tulips are just emerging, a lower concentration of nitrogen fertilizer is needed. 4. Water control

Before tulips sprout, generally do not need watering, water will cause seeds to rot, this period as long as keep the soil moist, if the climate is very dry, you can slightly water once or twice, the soil is enough. Water the right amount of water every day until the seeds germinate.

Of course, the problems that may arise in the survival of tulips can not be fully presented in this article, but what is mentioned in this article are some of the problems that tulips are most likely to face in the growth of tulips.
