Culture methods and matters needing attention of rhododendron

I. Culture methods

1. Fertilizer

In its growth period, to add fertilizer to it every 15 days, its roots are relatively thin, so it can not be too thick, otherwise it can not absorb, serious branches and leaves will be scorched off. If it is after flowering, nitrogen fertilizer should be added. In order to make it more robust, it is necessary to add phosphorus and potassium fertilizer to make the flowers look better when they sprout to bloom at the end of August. You don't need to get fat when it's below fifteen degrees in winter or when it's hot in summer.

2. Watering

It is best to add water in the morning or evening, and be careful not to water it at noon when it is hot, because the roots will be damaged and the flowers will be hurt. It should be watered thoroughly. If there is moisture, no water will be added. Add more water in spring and autumn, once every two or three days, but not too much when blooming, or the flowers will soon fade away. Summer is the time to grow up, the air is relatively dry, to water one or two times, do not rain for a long time, to sprinkle leaves, flowerpots should also be watered around, can increase humidity. The stagnant water should be drained out in rainy weather, and the water still volatilizes quickly after autumn, and it should be watered frequently. When the flower bud grows, it is necessary to control the water to help it differentiate. Moving it into the home after October can reduce moisture, which can help the tissue grow and resist the cold.

II. Points for attention

1. Its fastest growth is from April to June, which is the best time.

2. It likes fertile soil with strong ventilation and drainage, such as sandy soil. You can also mix it with rotten leaves, animal droppings, garden soil and sand. It is best to make sure that its PH value is between 5 and 5.5, which is slightly acidic.

3. It likes a wet environment with water. In its growing period, that is, summer and autumn, if it is very hot and dry, it is necessary to sprinkle water for it and the surrounding environment to ensure normal humidity, preferably 70-90%. If it is too dry, its leaves are not so green and may even fall.

4. It likes the environment of 12 to 25 degrees, 18 to 25 degrees from April to September, and 12 to 18 degrees from October to March of the following year. It likes the sun, but can not have too strong light, spring and autumn to give it about 50% shade, but also need ventilation, only in the morning and evening to let it see the light. If there is no light for a long time, although the leaves will grow thickly, they will not blossom. If you can block the sun during flowering, it can prolong the flowering time.
