Pines need a well drained, with stones and sand interspersed soil. The optimal mixing ratio is 2/3 soil and 1/3 sand. Torferde is not suitable. Heavy soil can be improved by the addition of sand. Possible materials for loosening the soil, also in planters, are lavagout, gravels, chippings, expanded clay or limestone quarry. Pines in pots need a location that provides at least three hours of sunlight per day for healthy growth. They are repotted every two to three years.
