Rainier Cherry Tree

1. Planting: The Rainier prefers full sun but will tolerate some shade - select a location that receives at least 6 to 8 hours of sunlight per day for best results. Also select an area with well-drained soil. When you're ready to plant, dig a hole that's three times the width of the root ball and just as deep. Place your tree, back fill the soil, tamp down and water to settle the roots. Spread a layer of mulch around the surrounding soil to preserve moisture.

2. Watering: During the growing season, if your tree receives at least an inch of rain every 10 days then no additional irrigation is necessary. If the season is hot and dry, then you may need to provide some additional water. The best way to water is by using a slow trickling garden hose left at the base of the tree. If you're not sure when to water, however, simply check the soil about 2 or 3 inches down. If the soil here is dry, it's time to water.

3. Pruning: A year after planting your Cherry Tree, prune during winter. Shape the tree to encourage horizontal branch growth with space between branches. And prune once a year as necessary to remove weak, drooping branches. 

4. Fertilizing: Fertilize in the spring and mid-summer using nitrogen fertilizer twice annually, applying 2 weeks after planting and 4 weeks after the first application. Use a complete fertilizer such as 10-10-10 - fertilizer application ratios vary upon the formulation, so be sure to follow package directions. When applying, be sure fertilizer is 6 to 8 inches away from the trunk around the tree.

Tips: In colder climates, avoid fertilizing after mid-summer to prevent new growth that won’t harden before fall frosts.
