As the dry season is just around the corner, you can conserve moisture content in your fruit tree plantation by mulching the trees with two inches of rice husk about a meter around the base.
The mulch will not only prevent fast drying of the soil, it will also prevent the growth of weeds. Photo shows a pummelo tree mulched with rice husk at the Teresa Orchard & Nursery in Teresa, Rizal.
Rice husk could also be used for mulching other trees, including young forest trees. Of course, you should regularly check the soil under the mulch to see if the tree needs watering.
