What kind of fertilizer is good for camellias in spring?

Many gardeners have potted camellias at home, but they lack experience in how to take good care of camellias. We will introduce them one by one based on several major breeding points. :

1. Soil is the basis for the growth of potted camellias. Because the roots of camellias depend on the soil for growth and development, the water and nutrients required for the life activities of camellias are mainly absorbed from the soil. Camellia prefers mountainous red (yellow) loam soil that is acidic, high in humus, loose and ventilated, with a pH value between 5 and 6.5. Alkaline soil or heavy clay soil cannot be used as a potted camellia substrate. Soil preparation: 50% mountain soil (mature red loam for planting crops), 40% sawdust or edible mushroom residue, 10% cake fertilizer powder or livestock manure and phosphate fertilizer powder, mix the three evenly, water appropriately, bag and mature, more than 20 days in summer and autumn, spring Winter lasts for more than 30 days. This kind of soil is not only loose and ventilated, but also retains fertilizer and water, which is suitable for the growth and development of camellia.

2. Camellia needs appropriate light, but it is afraid of direct exposure to high temperatures and scorching sun. In spring and late autumn, the camellias should be moved to the balcony or the ground where there is plenty of light to receive all-day light, which will promote the growth and development of the plant, promote the differentiation of flower buds, and make the flower buds strong. In summer, when the sun is strongest, the flower pots should be moved to a sunny and well-ventilated environment for maintenance. They can also be moved to the north balcony or under the south balcony for cultivation. You can also use a 75 shading net. From 9 a.m. Cover the plants by 5 p.m. to avoid direct sunlight, which may cause leaf trauma or withering of small plants. If possible, move the camellias under a awning to survive the summer safely.

3. Temperature is one of the important conditions for the growth of camellia. Camellia likes warmth, and the optimal temperature for growth is 18°C ??to 25°C, with a relative humidity of 60 to 65. For the growth of camellia, spring shoots usually sprout in mid-to-late March, begin to sprout in April, form terminal buds in mid-to-late May, stop growing, and gradually differentiate into leaf buds or flower buds. It takes 180 to 240 days from the formation of flower buds to flowering. Summer shoots sprout in late July and stop growing in early September. Although camellia is resistant to low temperatures, if a cold wave invades and the temperature suddenly drops below 0°C or a dry northwest wind occurs, it will cause frost damage to the twigs and the flower buds will wither due to frost damage. Therefore, move the flowerpot to the north to the south. Maintain it to survive the winter safely.

4. Camellia has many leaves, large leaf area, and fast transpiration. Camellia prefers a humid climate and moist soil. Therefore, it is necessary to replenish water for potted camellias. Water once a day during the spring and autumn growing seasons. Water once a day in the morning and evening during the summer, especially in the "dog days". If the ground is dry, water the ground and surrounding areas of the flowerpot or Spray water 1 to 2 times and maintain a certain air humidity, and the plants will grow luxuriantly. At the same time, please note that due to excessive watering, and most households water it with tap water, the soil in the flower pot will become alkalized over time. For this reason, when watering, add 0.5 to 1 liter of ferrous sulfate solution every month. You can also use 5 to 8 edible acid vinegar solutions to spray the leaves. Camellia likes moist soil, but is afraid of water accumulation in the flower pot. If water accumulates in the pot on rainy days, it must be drained out in time to prevent the roots from being soaked in water, suffocating and rotting.

5. Camellia is a fertilizer-loving flower. Because it is a strong tree with many leaves and a long flowering period, it needs a lot of fertilizer. During the fertilization process, apply enough liquid fertilizer, and apply enough long-term fertilizer in combination with changing pots. Depending on the size of the flower pot, apply 3 to 80 grams of decomposed cake fertilizer powder or dried chicken and duck manure per pot, and put it under the pot and mix it with the subsoil. According to the growth period of the plant, apply more organic fertilizer. Except for the coldest and hottest periods in winter and summer, apply decomposed dry cake water once or twice a month. The fertilization method is: peel off the soil around the pot for about 2 minutes, apply the liquid fertilizer into the ditch and cover it with soil to avoid odor. . You can also apply decomposed cake fertilizer powder on the edge of the pot and mix it with the pot soil, allowing the flowers to slowly absorb it. Urban flower lovers can go to the flower market to buy special fertilizer for flowers, which is hygienic and safe. In order to make the camellia grow better, during the peak period of camellia and peanuts, extra-root fertilization should be carried out once or twice a month, and the leaves should be sprayed with 0.2 to 0.3 potassium dihydrogen phosphate and 1 to 2 auxin. The principles of fertilization: it should be light rather than heavy, light rather than thick, less rather than too much. We must adhere to the method of applying thin fertilizer frequently, especially do not apply raw fertilizer.

6. Camellia likes to grow in an environment with moderate air flow. It likes the breeze the most. It likes the water vapor brought by the southeast wind, but is afraid of the northwest wind and strong wind, which will cause the water to evaporate too quickly. The supply and demand of camellias are out of balance, and the leaves of the plants are easily damaged, causing the plants to drop buds and flowers. In winter, camellias should be maintained in a sheltered and sunny environment with a certain temperature and humidity. In spring and autumn, the flowerpot should be moved to the balcony to allow it to be ventilated, light and swayed by the breeze. This will not only help the plant grow well, but also facilitate the differentiation of flower buds, the growth and development of flower buds, and reduce the occurrence of pests and diseases. Years of practice have shown that moderate ventilation and suitable lighting can prevent diseases and insect pests. What kind of fertilizer should be applied to osmanthus in spring?

Liquid fertilizer containing mainly decomposed nitrogen should be applied to osmanthus in spring.

Fertilizing osmanthus must be done after three osmanthus plantings. It is generally better to choose between March and May. Use compound fertilizer. If possible, plant ash organic fertilizer can be applied. Fertilization should be done on rainy days. If it does not rain, , please water it to enhance fertility.

In spring and early summer, in order to promote the sprouting and branching of sweet-scented osmanthus, liquid fertilizer containing mainly decomposed nitrogen can be applied every 10 days. How often should you water camellia cuttings in spring?

Under normal circumstances, it is about once a week. It is better to spray water frequently to increase the humidity. If the temperature is higher, it will take about a month to root. What kind of fertilizer is good for spring onions?

Onions require 13-15kg of nitrogen, 8-10kg of phosphorus and 10-12kg of potassium per acre. Pay attention to the application of phosphorus and potassium fertilizers, and avoid excessive nitrogen fertilizers, so as not to cause bolting or delayed bulb expansion due to excessive growth in the above ground. Keep the soil moist before and after spring sowing onion seedlings are unearthed, water frequently, and cultivate frequently. The growth period and the bulb expansion period are the periods when onions require the most fertilizer and water. Fertilizer and watering should be timely applied. 15kg of diammonium phosphate, 20kg of diammonium phosphate and 3 to 5kg of potassium sulfate should be applied to 667 square meters.

There is generally no top dressing after onion planting and before the seedlings slow down. After overwintering, apply overwintering water and apply 1,000 to 1,300kg of human excrement per acre. When the onions turn green in spring, apply green water together with the greening fertilizer. How often do you need to water camellia cuttings in spring?

Placement: Camellia should be placed in a warm, moist, ventilated and light-transmitting place. It needs sufficient sunlight in spring, and it is advisable to pay attention to shade in summer and avoid direct sunlight and western exposure. If it is placed on the balcony, it will often be sunburned to death accidentally. Watering: When cultivating camellia bonsai, the soil should be kept moist, but it should not be too wet to prevent it from drying out and getting wet at times.

Generally, you can water more appropriately in spring to facilitate germination and shoot growth; in summer, you should water early and late. It is best to spray water on the leaves to make them soaked. Do not water directly or fully with rapid water. It is not suitable to water hot water to avoid Water when the temperature is high around noon; water in an appropriate amount in autumn; in winter, water around noon, and spray water every two or three days. Fertilizer: Camellias like fertilizer. When potting, be sure to put base fertilizer in the pot soil, mainly phosphorus and potassium fertilizers. Fertilizers include decomposed bone meal, hair, chicken feathers, chaff ash, poultry manure, superphosphate and other substances. . It is not advisable to apply too much fertilizer at ordinary times. Generally, thin fertilizer and water are applied 2 to 3 times between April and May after flowering, and a slightly thicker water fertilizer is applied once in November in autumn. When using fertilizer, you should pay attention to the slightly larger proportion of phosphate fertilizer to promote more colorful flowers. Pruning: Camellia grows slowly and should not be over-pruned. Generally, just cut off the leggy branches, diseased branches, and weak branches that affect the shape of the tree. If there are too many flower buds on each branch, you can thin out only 1 or 2 flowers and keep them at a certain distance, and pick the rest as soon as possible to avoid consuming nutrients. In addition, flowers that are about to wither should be picked in time to reduce nutrient consumption and facilitate the healthy growth of plants and the formation of new flower buds. Repotting: Camellia bonsai can be repotted once every 1 to 2 years. The new pot should be larger than the old pot to facilitate the expansion and development of the root system. Repotting time should be in spring and April, but also in autumn. Combined with soil replacement, properly remove some of the hardened old soil, replace it with fertile and loose new soil, and combine it with placing base fertilizer. Prevention and control of pests and diseases: The main diseases of camellia include black mold, anthracnose, etc., which can be controlled by spraying 0.5 degree Bordeaux liquid. The main pests are tea moths. The control method can be to cut off the moths, usually from April to June.

Camellias usually need to be watered with neutral or slightly acidic surface water. Watering should be controlled when it is dry and then wet. When it is dry, water it again. Water it thoroughly, but be careful not to overdry it. Generally, water should be deducted appropriately before budding at the end of spring shoots to facilitate the transformation to reproductive growth, and water should not be cut off before flowering.

You can According to the moisture content, water the green water once before and after the Qingming Festival, and apply fertilizer once. In the future, the ground should always be kept moist, and watering should be stopped three or four days before the garlic sprouts are harvested.

Onions require 13 to 15 kg of nitrogen, 8 to 10 kg of phosphorus, and 10 to 12 kg of potassium per acre to make onions grow quickly.

Pay attention to the application of phosphorus and potassium fertilizers. Avoid excessive nitrogen fertilizer, so as not to cause excessive growth in the above ground and cause bolting or delayed bulb expansion. Keep the soil moist before and after spring sowing onion seedlings are unearthed, water frequently, and cultivate frequently. Onions are best during the leaf growth period and bulb expansion period. During the period of maximum fertilizer and water demand, fertilization and watering should be timely applied. 15kg of diammonium phosphate, 20kg of diammonium phosphate, and 3 to 5kg of potassium sulfate should be applied to 667 square meters.

There is generally no top dressing after onion planting and before the seedlings slow down. After overwintering, apply overwintering water and apply 1,000 to 1,300kg of human excrement per acre. When the onions turn green in spring, apply green water together with the greening fertilizer.

Onions have strong adaptability to soil, and fertile, loose, neutral loam with good ventilation is suitable. Sandy loam is easy to obtain high yields, but clay loam has plump bulbs, good color, and is resistant to storage. The onion root system has a weak ability to absorb fertilizer, so sufficient nutritional conditions are needed to achieve high yields. Every 1,000 kilograms of onions need to absorb 2 kilograms of nitrogen, 0.8 kilograms of phosphorus, and 2.2 kilograms of potassium from the soil. The application of copper, boron, sulfur and other trace elements can significantly increase production. How to pot camellias? Plant material formula, fertilizer, watering, etc.
