In order to prevent the growth of vanilla, it is necessary to plant deeply, control water strictly, bask in the sun more and bear cold properly. The specific points are as follows:
The planting time depends on the local temperature. It is usually planted when the temperature is 20 ℃ in a day. Early planting, quick germination, easy to grow in vain. If the temperature is higher than 20 ℃ during planting, the ball can be deeply buried and will not be watered temporarily. After the temperature is reduced, watering can be managed normally.
Arrange the snowballs in equal distance when planting. The smaller seed ball is placed on the periphery and the larger seed ball is placed in the middle. The large seed ball grows rapidly and is prone to lodging. The peripheral small plants can be used as support.
The best choice for planting vanilla is orchid basin, the depth is about 10 cm. Deep basin planting vanilla, plants grow upright, on the contrary, listless, prone to fall.
In addition, sufficient base fertilizer shall be applied when planting, and sufficient grass ash or bean cake shall be added into the soil. After the growth period does not need frequent topdressing, each time is thin liquid fertilizer can.
After planting, the potted plant shall be placed in a cool place. Before sprouting, the water shall be dry and wet, and the light shall be increased gradually after sprouting. Large water and high temperature will cause the growth of vanilla to be too fast, and the seedlings will be thin and slender. If this kind of mania occurs, it can be properly pruned. When pruning, do not cut flat, maintain a certain slope, so that the growth of the plant tends to be natural.
During the growth period of vanilla, it needs sufficient light. No matter in autumn or in winter, it is necessary to let the plants enjoy "sunbathing". Insolation can slow down the life of plants at that speed, which is the fastest way to control the growth of plants. But at noon in summer, avoid exposure to the sun, so as not to burn the plants. In addition, stop sunbathing at flowering stage, and proper shading will help to prolong flowering period.
It can bear low temperature, and grow slowly in low temperature environment, and can cultivate short and strong plant type. In winter, the plant can be placed outside for curing (the temperature is above 0 ℃), and the growth of the plant is good.
