The Malling series is a remarkable group of rootstocks developed for grafting apple trees, offering growers various options to control their tree's size and productivity. Originally created at the East Malling Research Station in England, these rootstocks have been carefully selected and tested to provide resistance against common pests like woolly apple aphid.
Malling series rootstocks thrive best in well-drained soils with a slightly acidic pH range of 6.0 to 7.0. Ensure your growing site receives adequate sunlight, preferably at least six hours of direct sun each day. Regular watering is essential during the tree's establishment phase and throughout the fruiting season.
When planting Malling series rootstocks, dig a hole deep enough to accommodate both the rootstock and the chosen apple variety. Space your trees according to their anticipated mature size, typically 6-10 feet apart. Mulch around the base of each tree with organic materials like bark or shredded leaves to retain soil moisture and suppress weeds. Prune your trees regularly to maintain desired shapes and remove deadwood.
Malling series rootstocks have been bred for disease resistance, but they may still be susceptible to certain pests. Monitor your trees for signs of woolly apple aphid infestations, which can cause stunted growth and reduced fruit quality. Treat with organic insecticidal soaps or horticultural oils if necessary.
Once established, Malling series rootstocks will produce a bountiful harvest of delicious apples. Depending on the scion variety grafted onto the rootstock, you can enjoy your fruits fresh off the tree, in pies and jams, or by sharing them with friends and family members. Remember to thin your fruit clusters during early summer to ensure each apple has enough space to grow large and develop full flavor.
