Remove any diseased or dead limbs from the Scotch pine with the gardening shears. Trim only new growth to give the tree the desired shape. A Scotch pine generally does not produce additional growth from a cut limb.
Water the tree only during periods of prolonged drought to encourage deep root development. A Scotch pine with an established root system can tolerate weeks of dry weather without harm. Water the tree thoroughly so the water reaches the roots.
Apply a 2-inch layer of mulch to the Scotch pine to help the tree retain moisture in hot climates. Add additional mulch in the spring to maintain a thickness of at least 2 inches.
Apply a granulated fertilizer high in nitrogen during the winter according to the manufacturer's instructions. Nitrogen encourages the growth of thick foliage that comprises the sculptured Scotch pine. This generally involves scattering a specific amount of fertilizer under the spread of the tree. The fertilizer should not come into contact with the trunk.
Propagate a Scotch pine in the summer with a cutting. Cut several inches from the end of an actively growing stem, using sharp pruning shears. Insert the cutting into well-drained soil and keep the soil moist until the cutting takes root. This may require more than a year.
