How to grow green apples

Green apple potted plants are the perfect combination of fruit tree gardening and bonsai art. Apple bonsai cultivation in the living room and courtyard can enjoy flowers, greenery, fruit appreciation, and fresh taste. But how to raise green apples? Let's take a look.

How to raise green apples

1. Principle of selecting pots: Generally, tile pots are used, which have loose texture, rough and simple appearance, good ventilation and drainage performance, are beneficial to root growth, and have low cost. You can choose a tile basin with a diameter of 30 cm, a bottom diameter of 20 cm, and a height of 30 cm with drainage holes.

2. Soil requirements: the soil can be taken on site, according to 5 parts of fertile vegetable garden soil, 2 parts of sieved coal slag, 2 parts of cooked manure, 1 part of rotten sawdust and fermented fertilizer of bone meal, then add 10 g of potassium dihydrogen phosphate Mix in proportion and sieve. The soil pH should be controlled between 5.4 and 6.8. And use small tiles to cover the small holes in the bottom of the tile basin, so that it can be ventilated without leaking soil.

3. Potting techniques: The seedlings should be self-breeding and self-planting. Choose grafted seedlings with robust plants, full bud eyes, and no damage from diseases and insects. Potted plants should be planted in the first half of March. , And cut off the necrotic roots, first put a small amount of nutrient soil into the bottom of the pot, put the seedlings, distribute the root system evenly, bury the soil and compact it, and water it in time to ensure survival.

4. Watering essentials: The frequency and interval of irrigation of potted apple trees should be determined according to the season, climate and soil moisture. The watering of potted apples should be based on the principle of "seeing the dry and seeing the wet, then pouring" to avoid watering every day and half-cutting. During the germination period, flowering period, and fruit expansion period, water should be added in time. In June, in order to promote the differentiation of flower buds, proper water control is required, and watering should be less during the rainy season from July to August.

5. Fertilization requirements: After the leaves fall in autumn, the surface soil in the tile basin should be taken out, replaced with freshly prepared loose and fertile nutrient soil, and then irrigated to settle. During the growth period, the thin organic fertilizer can be poured once a week, and remember to apply it less frequently to prevent burning roots and facilitate absorption and reduce the loss of fertilizer liquid. When the chamber temperature is lower than 18 ° C, all forms of topping should be stopped.

6. Illumination requirements: It is native to the tropical American nature and enjoys high temperature and humidity in a half shade environment. It is afraid of the cold and avoids strong light.

7. Temperature requirement: growth temperature is 18 ℃ ～ 30 ℃, high relative humidity is required, avoid dry soil and environment, like warm and peaceful environment, not resistant to extreme heat, fear of high temperature, and poor cold resistance, late spring and summer Initially, when the ambient temperature exceeds 25 ° C, it should be shaded, cool and well ventilated, and moist and half shaded. In winter, the ambient temperature is not lower than 10 ° C. When the room temperature is lower than 5 ° C, the above-ground part will be seriously frozen. Under normal circumstances, before the end of autumn when the ambient temperature drops to 10 ℃, the main insulation should be turned off in time.

8. Insect pest prevention: It is necessary to observe the pest control frequently, and apply pesticides when encountering insects.

9. Pruning method: adopt the method of coiling and pulling branches to suppress the growth of the tree body, promote new branches, topping the branches that were drawn that year, and promote the trunk to reissue new branches. For long legs and competitive branches, combined with pulling branches for twisting, topping, nicking, and ring stripping, a large number of fruiting branches can be cultivated, and they can be promoted to form flower buds, so as to achieve the goal of early fruiting and multiple fruiting.

Precautions:

1. When cultivating green apple trees, watering or less watering is not required during the rainy season. In case of continuous rain, the water should be drained in time and the bonsai should be moved to the rain shelter.

2. The soil acidity and alkalinity of the green apple planting soil should be slightly acidic to neutral. When the PH value is above 7.8, it is prone to lack of elements and lose green.
