Growth Stages

1

Establishment

1-2 years

Young tree develops root system and main framework branches. Growth is moderate and focused on establishing a strong structure.

Water regularly, stake for support, prune to establish open center form, apply mulch around base, protect from harsh winds

2

Flowering

2-4 weeks

Abundant flower buds develop on previous year's wood. Delicate, fragrant flowers emerge in late winter to early spring in shades of white, pink, or red depending on variety.

Do not prune during flowering, ensure adequate chill hours (600-900 hours below 45°F) were received, protect blooms from late frosts if possible

3

Leaf Development & Fruit Set

4-6 weeks

Leaves emerge after flowers fade. Small green fruits develop from pollinated flowers. Tree focuses energy on growth and fruit expansion.

Begin light pruning to maintain shape, thin fruits if overly abundant (space 2-3 inches apart), apply balanced fertilizer, maintain consistent moisture

4

Fruit Development

8-12 weeks

Fruits grow from marble-sized to their final size (1-1.5 inches), gradually changing from green to yellow or green with red blush depending on variety.

Water deeply during dry periods, apply mulch to retain moisture and regulate soil temperature, monitor for pests, avoid excessive nitrogen which promotes foliage over fruit

5

Harvest & Dormancy

1-3 months

Fruits ripen to full color (late May to July depending on climate and variety). Leaves may show fall color before dropping in late autumn. Tree enters dormancy.

Harvest fruits when fragrant and slightly soft, light pruning after harvest to maintain shape, reduce watering in winter, apply dormant oil spray if needed

Companion Planting

Plant with:

Avoid planting near:

Black walnut (produces juglone) Shallow-rooted plants that compete for water Plants sensitive to frost damage (oume flowers early, affecting nearby sensitive plants)

Common Pests

  • Prune infested branches, drop cloth collection of fallen fruit, spinosad or neem oil spray during fruit development, parasitic wasps

  • Dormant oil spray in winter, insecticidal soap, horticultural oil, pruning of heavily infested branches

  • Remove and destroy infested branches, proper tree care to reduce stress, wrap trunk to prevent egg laying, pheromone traps

  • Remove infected leaves, improve air circulation, fungicide application (copper or sulfur), avoid overhead watering

  • Remove infected fruit and branches, improve air circulation through pruning, fungicide during bloom and fruit stages, sanitation of fallen fruit

Harvest Tips

Harvest fruits in late May through July when they are fragrant, slightly soft to touch, and have developed full color (typically yellow or yellow-green with possible red blush). Pick fruits that yield slightly to gentle pressure. Fruits do not ripen significantly after picking, so harvest at peak ripeness. For umeboshi (pickled plums), harvest when fruits are fully mature but still slightly firm.

Fun Facts

  • 🌱 Oume is not truly an apricot or plum despite its English names—it is botanically distinct from both, representing its own valued species within the Prunus genus. The name 'ume' (梅) specifically refers to Prunus mume and carries deep cultural significance in Japan and China spanning thousands of years.
  • 🌱 Japanese White Eye birds (mejiro) are attracted to oume blossoms and are traditionally considered symbols of good fortune in Japanese art and gardens where oume trees are planted.
  • 🌱 A single oume tree can produce hundreds of fragrant flowers, and a mature tree may yield 50-100 pounds of fruit annually, making it both a spectacular spring display and a productive food source.
