Sweet potato planting time and method: sweet potato vine how to plant methods, sweet potato planting time

Do you know how sweet potatoes are grown? Sweet potatoes are generally grown with sweet potato vines. Sweet potato seedlings are first sent out with old sweet potatoes, and then sweet potato seedlings are pruned. Generally, two to three nodes with long leaves can be planted as a sweet potato seed. If you want to propagate new plants, you can use the sweet potato vine cut for the first time, or use the sweet potato vine harvested this time to re-cut and propagate. Let's take a look at what sweet potato planting needs attention.

Soil: loose loam soil that has been mixed with organic matter many times. (As long as the used soil is free of pests and diseases, both Yangmingshan soil and culture soil can be used)

Container: 40 cm deep, 30 cm diameter round basin. This time using a deep basin, the roots grow down to form a block root, so 4 have been presented crowded phenomenon.

Cutting: about 4~5 nodes down from the tip, cut off strong branches and insert them into the soil. One must go deep into the ground to take root. The leaves grown from sweet potatoes are very large, almost 3 to 5 times larger than those of edible sweet potatoes. Because of the rough feeling, the leaves are not cut in half to reduce water evaporation.

Fertilization: Because the container is deep, it is still a long distance for the root to grow, so apply organic fertilizer as base fertilizer at the bottom layer, apply fish essence every week in the future, and apply organic fertilizer every two months. The growth period is 5 to 6 months, and fertilizer can be given in small amounts and multiple meals, or sufficient fertilizer can be given once every 2 months.

Watering: When pulling out sweet potatoes, thin or thick roots are covered with the whole basin, so the soil surface often presents a state of water shortage at ordinary times. Pay attention to supplementing enough water to avoid yellowing and falling of old leaves, which affects growth due to excessive leaf loss.

Harvesting: 10/5 Found a small sweet potato floating above the soil surface, because the surrounding space has been occupied by other sweet potatoes, can not go deep into the soil. The average growth period is 150 - 180 days.

Note: The leaves grown from sweet potatoes are rough and unfit for consumption. If leaves are collected frequently, nutrients are consumed on the long leaves instead, which may make the underground roots grow less.
