How to Grow Plum Tree

Soil, care & harvest

As an established tree, you do not sow seeds annually; instead, purchase a young nursery stock or start from seed months before planting outdoors. If starting from seed indoors, begin in early winter for spring transplanting. Ensure your soil pH falls between 6.0 and 6.5 with good drainage. Plant the root ball at the same depth as it was in its container to encourage healthy establishment.

Space trees 15 to 20 feet apart to allow proper air circulation and sunlight access, which prevents disease. Water moderately during dry spells, aiming for deep soaking rather than frequent shallow watering. Apply a layer of organic mulch around the base to retain moisture and regulate soil temperature. Feed annually in early spring with a balanced fertilizer to support fruit production.

Watch for common issues like plum curculio beetles, which cause scarred fruit, and fungal diseases such as brown rot. Prevent pests by inspecting regularly and using row covers or organic sprays if infestations appear. Harvest plums when they yield slightly to gentle pressure; timing varies by variety but typically occurs in mid-summer through late fall depending on the specific cultivar.
