depth and frequency .Seeds and seedlings need topsoil moisture.Deep-rooted plants need moisture, which promotes good root development.
Avoid excessive watering !It is necessary that the ground was wet only 15 cm from the surface.On the roots of wetland soil deprived of oxygen and lose their ability to deliver water and nutrients to the top.If the edges of the foliage turns brown and begins to fall, you may have filled in the plant.
