How to plant dragon spitting pearl seeds

It is appropriate to sow Longtuzhu seeds in April, soak them in clean water for about 12 hours before sowing, and then fish them out to dry. Then the treated seeds are sown in the pit, covered with soil and watered, and seedlings can emerge in about 10 days. Maintenance should be done well after emergence.

Longtuzhu maintenance

1. Light

Spitting beads need plenty of light in winter and shade when the summer weather is too hot, otherwise the leaves will turn yellow. When the light is insufficient, it will cause vine growth and do not blossom. Flower bud differentiation is not affected by photoperiod, but strong light can promote flower bud differentiation and development. It should not be kept in the dark for too long. If the temperature is above 21 ℃, the flowers will fall for more than 24 hours.

two。 Fertilizer application

The fertilization of Longtuzhu should not be too much, once every semimonthly, during the flowering season, the mature thin cake fertilizer and water should be applied every 7-10 days, 3-4 times in succession, and 1-2 times of phosphorus and potassium fertilizer. In winter, watering is reduced and fertilization is stopped.

3. Watering

Summer high temperature season should be fully watered and properly shaded. It is necessary to reduce watering in winter and make it dormant in order to survive the winter safely.

4. Pruning

When changing the basin every spring, the aboveground branches should be trimmed and cut short, the height of the branches should be strictly controlled during the growing period, and attention should be paid to topping and coring. Half a month after coring, Bijiu or dwarftin was applied to control the height of the plant.

In addition, during the maintenance period, we should also pay attention to the prevention and control of leaf spot, shell insects, whitefly and other diseases and insect pests, which can be sprayed in advance.
