How long after sowing peanuts do you need to earth up the soil?

In order not to affect peanut growth, peanuts need to be earthed up once the plants reach a certain stage, so how long after planting peanuts should you earth up?

1. What is earthing up?

Earthing up means that after the crop is planted, the land is weeded and the ditches are tidied, a cultivator is used to turn the soil between the crops, and the soil that is turned up is placed over the root area of the crops.

Some crops need more soil around the roots to grow well, and at the same time weeding is carried out, and the field ditches can also be tidied to help drainage.

2. How long after planting peanuts should you earth up?

Peanuts can be earthed up when they reach the full-flowering stage of a single plant and before the plant population closes the rows; generally earthing up is done twice, once at the full-flowering stage of a single peanut plant, and once again 10 days later.

3. How are peanuts earthed up?

1. Single-row ridge planting

A large hoe can be used with a grass ring fitted at the junction of the hoe blade and the hoe hook; work backwards with deep hoeing and a strong pull to scrape off the hardened crust on top and completely eliminate the weeds protecting the roots. When hoeing deep, be careful not to loosen the pegs that have entered the soil, and when scraping and hoeing, do not bruise the fruiting branches. When mounding soil to build up the ridge, do not press the vines.

2. Double-row ridge planting

First use a large hoe to hoe deep into the ridge furrow, lightly scrape the back of the ridge, and remove the dry, hardened soil layer on the ridge, then use a cultivating hoe to go through the furrow and earth up. Earthing up should ultimately bring the peanut ridge to the standard of “clean furrows, loose soil, concave top, plump waist”, so as to help pegs from high nodes enter the soil and set fruit.

When earthing up, you can combine it with clearing the border furrows and place the loose soil at the base of the peanuts, paying special attention to earthing up the edge rows so as to give full play to the growth advantage of the edge rows. Also note that earthing up too early will affect the growth of the base of the stems and branches and flowering and peg formation, while earthing up too late, because the peanut plant population has closed the rows and large numbers of pegs have entered the soil, makes cultivation inconvenient and easily loosens the pegs that have entered the soil.

Therefore, earthing up must be done at the right time.
