Oak acorn seeding is a natural method for reforestation. It allows the Tabor oak's characteristic deep tap root to grow quickly, reaching soil depths at which moisture levels and constant temperature promote root development. Direct seeding is cheaper and less complex than planting, since there is no need for a planting pit or for nursery seedling preparation.

In the experiments described here, we tested the effectiveness of a number of seeding site treatments: use of tree shelters, mulching with plastic sheeting, summertime irrigation, and the addition of a water- and nutrient-containing polymer (Barbary Plante).

Our results showed that using tree shelters, spreading plastic sheeting, and using Barbary Plante, all significantly improved the survival and development of the seedlings. Use of the sheeting mulch also removed the need for summertime irrigation, even in arid planting sites in southern Israel.
