Cultivation methods and precautions for potted lemons in the north

The cultivation methods and precautions of lemon potted plants are as follows:

Cultivation method: 1. Moisture: Lemon trees like a moist growth environment, and daily maintenance needs to replenish water in time.

2. Temperature: The suitable growth temperature of lemon trees is 17 19.

3. Potting soil: Potted lemon trees need to choose soil with good air permeability and drainage.

Precautions: 1. Lemon trees like moisture, but they are afraid of waterlogging, and they should not be too much for daily maintenance and watering, and they can keep the potting soil slightly moist, and the water evaporates quickly in summer, so they can sprinkle water around the plant to increase humidity.

2. Lemon trees grow better in a place with sufficient light, insufficient light will cause the branches and leaves of the plant to grow, and the light is strong in summer, so it needs proper shade. When the temperature is below 2 in winter, the growth of the plant will be affected, and it is necessary to move it to a warm place indoors for maintenance, or take protective measures.

3. When fertilizing lemon trees, it should be noted that the concentration of fertilizer should not be too high, and raw fertilizer can not be applied, and water can be properly replenished after fertilization to promote nutrient absorption.

1. Soil: The requirements for the use of cultivation medium are not very strict, and only need to have a certain air permeability and a certain amount of nutrients.

2. Light: It prefers to grow under abundant light, but it is still necessary to properly shade the sun in summer. It is grown between 15 and 27 degrees Celsius, not above 35 degrees or below freezing.

Winter maintenance should be taken back indoors, away from radiators and air conditioners.

3. Watering: keep its water demand moderate, not too much and not too little, you can water more when the weather is dry, and it is advisable to reduce the water supply when it is raining continuously.

4. Fertilization: Apply enough base fertilizer once before planting, and increase the number of fertilization during the vigorous growth period, but it is advisable to reduce the amount of fertilizer.

Seeding and propagation: It is generally propagated by seed planting, collecting some of its mature seeds, and then sowing it directly into moist soil, so that it will germinate after a period of maintenance.

Pruning: Prune all the branches that are not growing well or have died, so that they can be controlled to sprout new shoots.

Due to the dry weather in the north, disease cases of the plants are rare. However, there will also be some harm from red spiders and scale insects, which should be removed in time after being found.

1. Lemons are recommended to be planted from mid-March to mid-June. Please prepare lemon seedlings, a slightly larger pot, soil for the cultivation of fruit trees, sand and gravel. Put some sand and gravel at the bottom of the new pot and put about 1 3 soil.

Remove the seedlings from the nutrient cup and place them in the pot. Fill the pot with soil and fix the seedlings with a lot of water, so that the water is drained from the bottom of the pot, and the soil will seep and be compacted after watering, so that the seedlings will not shake.

2. After planting lemons, we need to take measures to prevent the stems from breaking or falling off when it is blown by strong winds.

3. When the branches increase too much after they begin to grow, due to the growth of the branches, the nutrients of the prunus may be too much, and they may not bloom, so some branches need to be pruned off.

Potted lemons need to choose a diameter of 20 30cm, 15cm high clay pot as a container, but also with garden soil, humus mixed spraying ferrous sulfate to make the soil, usually to give it enough light, otherwise it is easy to reduce its ornamental value, do not need to apply any fertilizer, but need to water it a lot, autumn must pay attention to pruning.

1. Potting soil selection

Potted lemon cultivation lemon first needs to choose a diameter of 20 30cm, a height of 15cm clay pot as a container, but also to choose loose, well-drained, weakly acidic soil as a substrate, generally can be mixed with garden soil, humus, and then spray an appropriate amount of ferrous sulfate.

2. Sufficient light

In the cultivation methods and precautions of potted lemons, lemons like to grow in full sunlight plants, generally potted lemons need to be placed in a sunny place, do not place it in a cool and ventilated place, otherwise it will make potted lemons unable to bear fruit, and even reduce the ornamental value of potted lemons, do a good job of shade and sun protection every summer.

3. Water and fertilizer management

Potted lemon spraying does not need to fertilize it, it can rely on the nutrients in the soil to grow normally, but it needs a lot of watering, generally we need to water every 2 3 days, increase the amount of watering in summer, so that the soil can be kept moist for a long time, and the winter needs to keep the soil dry.

4. Reproduction method

Generally, potted lemons are propagated by grafting and cuttings, but the survival rate of propagation by cuttings, and the operation steps are also very simple, first pick the strong branches, and then disinfect the wounds of the branches, insert them into the slightly acidic potting soil, wait for the rooting and germination, and turn the pot and change the soil in the spring of each year.

Potted lemons are very cold-tolerant, so they don't need to be kept warm in winter, but in autumn, they should be properly pruned, and we can cut off all its weak branches and diseased branches, which can greatly reduce soil nutrient consumption, and can also help potted lemons overwinter and make them grow better.

The cultivation method of potted lemon mainly lies in the following aspects:

Spring pruning and changing pots and changing soil Potted lemons grow robustly, to ensure better growth to prune, the best time for pruning is in spring, at this time to combine repotting spring shears, cut off dead branches and fallen leaves, pests and diseases, long branches and other parts, so that the plant can hang fruit growth.

For potted lemon flowers, the potting time should be carried out between March and April during the Spring Festival to increase the nutrients required for growth and the growth of the plant.

Precautions When pruning, be careful not to cut the main branches and young branches and leaves.

When changing pots, choose pots that are suitable for the size of lemon plants, not too big or too small, and apply bottom fertilizer to the bottom of the pot when changing soil.

Proper fertilization <>

Before the lemon plant blooms and after the fruit hangs, it is necessary to top dress, apply multi-element flower fertilizer every other month, and spray flower nutrient solution every half month.

Precautions The fertilizer to be fertilized is multi-element flower fertilizer, do not apply other fertilizers, so as not to damage the roots and affect the growth.

Fertilization should be done in moderation, according to the growth trend, large plants can be fertilized more, and small plants should be fertilized less.

Pest control <>

Hot summers and cool autumns are the seasons when pests and diseases are common, so it is necessary to carry out proper control in such cases.

To control pests and diseases, it is necessary to spray anthers every half a month.

Precautions When spraying, it is best to pay attention to the spraying time at about 9 o'clock in the morning, or about 4 o'clock in the afternoon, and do not spray in the scorching sun at noon, otherwise it is easy to cause pesticide damage.
