Thin your plants when they are approximately 8 to 10 cm tall, so they are 20 to 30 cm apart. Take care to not damage the roots when weeding.

Zea mays grows best on well drained and fertile loamy or alluvial soils. However, it is possible to grow maize on a wide variety of soils ranging from sand to clay. The crop is tolerant to soil acidity, neutralizing soil acidity through liming can increase yields.
One reason why maize is grown all over the world is its ability to grow in a wide range of agro-climatic conditions. However, moderate temperatures and rainfall are most favorable for the crop.
