Mayday Tree

Mayday Tree (Prunus padus) Care Guide

Overview:
The Mayday Tree is a deciduous flowering tree prized for its clusters of fragrant white blossoms in spring, glossy fruits in summer, and seasonal interest in autumn. It is hardy and relatively easy to grow, often used as an ornamental specimen or landscape accent. (Also called Bird Cherry or Bird-Cherry) 

1. Planting & Growing Conditions

• Hardiness Zone: Zone 3 and up — quite cold-tolerant. 

• Mature Size: Typically 20–30 ft tall and wide (in suitable conditions) 

• Sunlight Needs:

  • Full sun is ideal for the best flowering. 

• Soil Requirements:

  • Prefers fertile, well-drained soil. 

  • Avoid waterlogged or poorly drained sites. 

• Spacing: Plant with enough room to spread — the mature crown can get wide, so allow adequate clearance from structures.

2. Watering & Establishment

• Young Tree (First Season):

  • Water regularly to keep the root zone moist but not soggy.
    

  • Established Tree:

  • Tolerates moderate drought but benefits from supplemental watering during extended dry periods. 

  • Be cautious of overwatering in poorly draining soils.

3. Fertilizing

• Apply a balanced, slow-release fertilizer in early spring to support healthy growth and flowering.

• Use compost or well-rotted organic matter as a soil amendment when planting.

4. Pruning & Maintenance

• Best Time to Prune: Late winter to early spring, while the tree is dormant. 

• How to Prune:

  • Remove dead, diseased, or damaged branches.

  • Thin crowded areas to improve air circulation. 

  • Avoid heavy pruning because wounds may invite disease in Prunus species. 

5. Flowers, Fruit & Seasonal Interest

• Bloom Time: Late spring — produces showy racemes of white, fragrant flowers. 

• Fruit:

  • Small dark cherries appear in summer. Birds are attracted to them. 

  • The fruits are not typically eaten by people because of bitterness. 

• Foliage & Fall Color:

  • Leaves are glossy green; in fall they may turn yellow or bronze before dropping. 

6. Pests & Diseases

• Common Diseases:

  • Black knot fungus is known to affect wild cherries and related Prunus species. 

  • Silver leaf disease is another concern—avoid pruning when conditions are favorable for infection. 

• Pests:

  • Watch for aphids, borers, and other common tree pests.

  • If disease occurs, prune out affected limbs and dispose of them (do not compost).

7. Winter & Cold Protection

• Very cold hardy — usually no special protection needed in zone 3 and colder climates.

• In extremely harsh winters or in exposed locations, a light protective mulch around the base may help.
