Espaliering (growing trees on a lattice or trellis) a fruit tree provides several benefits. The wall provides warmth and protection from cold winds. A peach tree grown on a wall requires less space because of its flat profile, but still produces quality fruits. Espaliers on walls also have decorative appeal and can take on several different design patterns. Growing peach trees against a wall takes several years of careful pruning and maintenance.
Select a southern facing wall that receives at least six hours of sun. Install a support system or trellis on the wall. Use eyebolts, masonry staples, concrete nails or vine ties to attach the tree to the wall.
Plant the tree approximately 6 to 8 inches away from the wall or support. Dig the planting hole twice as wide as the root ball or planter. Place the tree in the hole, with the top of the roots level with the soil line.
Fill the hole with water. Allow it to drain and backfill the dirt. Water again until the soil settles. Apply a 3-inch layer of mulch.
Cut off all branches that grow at a right angle to the wall, using bypass pruners. Prune any branches that don't fit with the desired design of the espaliered peach tree. Top the leader to approximately 30 inches tall, leaving three to five buds below the cut.
Apply fertilizer formulated for fruit trees every three months while the tree develops. Once it obtains the desired size and shape, fertilize in the fall and spring.
Bend and tie the remaining branches to the support, keeping the tree flat and parallel with the wall, during the second year of growth.
Prune the tree annually to maintain the flat profile and to top the new central leader. Continue to tie branches to the support as needed to create the pattern of the espalier. Maintain space between branches for proper airflow.
