Many farmers focus on fertilizer, seeds, and spraying, but they forget one simple practice that can greatly improve maize production — earthing up. Yes, you can and should do earthing up in maize
.
Earthing up means pulling soil around the base of the maize plant to form a small mound. This practice is usually done when the maize is about 3–5 weeks old, especially after weeding.

Why should farmers practice earthing up?

1. Stronger plant support
   Earthing up helps maize plants develop stronger roots and prevents them from falling over during strong winds.
2. Better root development
   When soil is added around the base, maize produces more supportive roots, which improves nutrient and water uptake.
3. Moisture conservation
   The mound of soil helps retain soil moisture, which is very important during dry periods.
4. Weed suppression
   Earthing up helps bury small weeds, reducing competition for nutrients.
5. Higher yields
   Healthy and stable plants lead to better cob development and higher productivity.
   Many farmers lose maize simply because plants lodge (fall) or develop weak roots. A few minutes spent earthing up can protect your crop and increase your harvest.
