• Plant Rainier cherry trees in late winter to early spring when they are dormant.
• Dig a hole twice as wide as the root ball and of the same depth.
• Gently spread the roots and place the tree in the center of the hole.
• Backfill with soil, ensuring the graft union is 2 inches above the soil surface.
• Water thoroughly after planting.

**3. Spacing:

• Plant Rainier cherry trees at least 20 feet apart to allow for proper air circulation.

• Watch for diseases like brown rot and bacterial canker; apply appropriate fungicides if necessary.

**8. Mulching:

• Apply a 2 to 4-inch layer of organic mulch around the base of the tree.
• Mulch helps conserve moisture, suppress weeds, and regulate soil temperature.

**9. Support System:

• Stake young trees if needed to provide support against strong winds.

**10. Harvesting: - Rainier cherries are typically ready for harvest in late spring to early summer. - Harvest when the fruits are fully ripe, firm, and have developed a yellowish blush.
