How many days does it take for sweet potatoes to grow slowly after planting?

After planting the sweet potatoes , we must pay attention to the management of the seedlings, so as to ensure that the seedlings grow quickly, take root early, have a high survival rate, and grow vigorously, which is conducive to high yields. So how many days does it usually take for sweet potatoes to grow slowly after planting? Let’s learn more about it below.

How many days does it take for sweet potatoes to grow slowly after planting?

It usually takes about 7-10 days for sweet potatoes to complete the seedling acclimatization process after planting. During this period, the sweet potato seedlings will gradually adapt to the new environment from the state just planted in the soil and begin to spread their leaves and grow. After the seedlings have grown slowly, the sweet potato seedlings will enter a rapid growth period and begin to accumulate nutrients in preparation for the subsequent enlargement of the tubers.

What are the key points in managing sweet potato during the seedling stage?

1. Check and replenish seedlings

After sweet potatoes are planted, they often fail to germinate due to drought, insect pests and other reasons. If there is a shortage of seedlings, it is necessary to supplement them after planting. At the same time, appropriate fertilizer should be applied to the place where the seedlings are supplemented after the seedlings have accumulated some nutrients to promote their growth.

2. Intertillage and weeding

Intertillage and weeding should be carried out from 10 days after seedling planting to before ridge closing, and every 10-15 days until completed 2-3 times. After inter-cultivation, if rain causes the ridges to collapse, soil should be added in time to protect the tubers and roots.

3. Reasonable topdressing

Apply fertilizer to the seedlings in time. For barren land or land without basal fertilizer, apply a small amount of quick-acting nitrogen fertilizer to promote stem and leaf growth, generally 5-10 kg per mu; for fertile land and land with sufficient basal fertilizer, there is no need to apply fertilizer everywhere, only apply seedling-promoting fertilizer to weak and small seedlings, and apply fertilizer in holes. Apply more fertilizer to the supplementary seedlings.

4. Watering tips

During droughts, small amounts of water should be used for irrigation to avoid flooding, and the soil should be tilled and loosened in time after watering. Drainage ditches should be dug in time in low-lying, flood-prone or rainy areas to prevent excessive water accumulation from affecting the growth of sweet potatoes.

5. Pest and disease control

Do a good job in disease and pest prevention and control. If a disease occurs, use medicine to prevent and control it in advance. For example, insect pests. In June and July every year, many pests appear and harm sweet potato leaves . In this case, pesticides can be used for prevention and control in advance.

In general, the sweet potato seedling period has an important impact on the later growth and yield of sweet potatoes. The implementation of the above measures can help sweet potatoes successfully pass the seedling period and lay a good foundation for subsequent growth and yield.
