Sophora japonica cultivation methods and precautions

1. Maintenance methods

1. Temperature: It likes to grow in warm places. Places with temperatures below fifteen degrees are not suitable for growing plants. It will stop growing at low temperatures. This is a self-protection function. The maintenance temperature should be kept between 20 and 25 degrees, at which the plant grows best.

2. Watering: It consumes a lot of water during the growing period, and it likes to grow in a moist place. Therefore, the frequency of watering must be increased during the growing period. Because the roots are not tolerant to waterlogging, avoid water accumulation in the potting soil when watering. Generally, it is best to water it every two days.

3. Fertilization: It is a fertilizer-loving plant. During the growth period, it is necessary to ensure sufficient nutrients so that the plant can grow strong. It should be noted that do not apply too much fertilizer. Thin fertilizer should be used as the main fertilizer. It is best to dilute the fertilizer before using it on the plant. Water it once after fertilizing to avoid burning the roots due to excessive fertilizer concentration.

4. Light: The growth of plants cannot be separated from light. Adequate light is very beneficial to the growth of plants, especially during the growth period. It is necessary to expose it to more sunlight. The light in summer is relatively strong, so the plants need to be shaded.

2. Breeding techniques

1. Reproduction: It can be propagated by sowing. Select healthy and plump seeds, soak them in warm water for 24 hours, then mix the seeds with fine sand and place them in a ventilated place at about 20 degrees. They will germinate in about a week.

2. Weeding: It grows very fast, especially during the peak season, and will produce a lot of weeds. In order to avoid weeds competing with plants for nutrients, weeding must be done regularly. Do not use pesticides for weeding. Manual weeding should be the main method, because pesticides can easily affect the growth of plants. Manual weeding will be safer.

3. Problem Diagnosis

1. Pests: The plant is easily infected by the locust moth, which is a leaf-feeding pest that eats the leaves of the plant. If the plant is found to be infected, it is necessary to spray the plant with moth-killing pine emulsion.

2. Disease: If the flowers fall off and the edges of the leaves are burnt, it is mostly caused by improper watering. You need to adjust the maintenance temperature and control it at around 25 degrees. Wait until the accumulated water in the potting soil is completely dry before watering.

IV. Other issues

1. Edibility: Its flowers are edible.

2. Flower language: Its flower language is deep love of spring.
