How to cultivate lilac

1. Maintenance methods

1. Temperature: Warmth is more suitable for its growth and will also help it bloom. In addition, among its habits, it has relatively good cold resistance. Generally speaking, unless you live in a place too far north where the temperature is very cold in winter, there is no need to take precautions against the cold.

2. Light: Adequate sunlight is helpful for its growth, as well as its subsequent flowering and fruiting. If it is placed in a very dark environment, it may not bloom, or the number of flowers may be very small. So, unless it is too strong, there is no need to block out the light.

3. Watering: It likes places with plenty of water. Wild plants are generally distributed in relatively humid hillsides and other places. Therefore, you need to water the plant sufficiently on a regular basis, but try not to overwater it, otherwise it will be prone to diseases.

4. Fertilization: Normally, not much fertilizer is needed, so you can choose to sow it in a place with fertile soil. After that, top dressing can be done once a month or two months. During the flowering period, pay attention to the application of phosphorus fertilizer.

2. Breeding techniques

1. Reproduction: It is best to use the sowing method for reproduction. The seeds must first be germinated, preferably soaked in water at 40 to 45 degrees, then soaked in cold water for two days and treated with potassium permanganate. It can be sown in rows or broadcast. After sowing, the thickness of the soil covering can be about 1.5 cm. After that, the soil needs to be watered thoroughly and then shielded from strong light.

2. Pruning: Pruning of branches and leaves is more important in spring. The first step is to pinch the tips of the plants, which not only allows for more branches, but also allows for more flowers to bloom later. Dry and yellowing leaves should also be cut off. Also, prune the branches after flowering.

3. Problem diagnosis and treatment

1. Diseases: The main types are some fungal diseases. For example, "leaf blight" and "wilt disease". It is particularly prone to occur in summer and can be treated in time with corresponding medicines. In addition, too much watering can easily lead to "root rot", and medicine can be used to repair the root system at the same time.

2. Pests: There are "caterpillars", "moths", etc., which are also common in summer. You can spray insecticide immediately.
