Care for a wild plum tree by planting it in a suitable location, watering it well, fertilizing it regularly and pruning it when necessary. You need gloves, pruning shears, a hand saw, fertilizer and mulch.
- Choose a suitable location
Place a wild plum tree in a location with full sunlight. It needs loose, well-draining soil. During the growing season, keep the area under the tree's canopy free of weeds.
- Water the tree
During the first year after planting, water the tree abundantly. Afterward, water it only during dry spells. Spread mulch around the base of the tree to help with water retention, but be sure the mulch stays 6 to 8 inches from the trunk.
- Fertilize the tree
Fertilize the wild plum tree once in early spring and once in midsummer. Use organic fertilizer, manure or compost. Spread the fertilizer around the base of the tree, but keep it away from the trunk.
- Prune the tree
In late winter, prune dead, broken or diseased branches, or branches that rub against each other. Thin out about one-third of the canopy. Make clean cuts with pruning shears or a hand saw above healthy buds. Trim away suckers that grow from the roots and watersprouts, or vertical suckers, that grow higher up the tree. Shape the tree to keep it upright and rounded.
