Pears require full sun. Be sure to choose a spot that will ensure at least 6-8 hours of sun, not only for your sapling but for your full grown pear. Dig your hole wide and deep, mixing mix plenty of compost into the soil. Remove the tree from its container and set it in the hole to the same depth it was in its container. Gently spread the roots and refill the hole with the amended soil. Water well and continue to water regularly – once or twice a week – until the roots are well established.
