Instructions

Things You’ll Need
  • Soil pH test
  • Shovel
  • Organic compost
  • Water
  • Organic mulch
  • Slow-release tree fertilizer
  • 5-gallon bucket
  • Drill
  • 1/4-inch drill bit
  • Ground rock sulfur
    1. Choose an area to plant the flowering dogwood that has a well-draining soil and acidic pH. Test the soil pH before planting to verify the pH is 5.0 to 6.5. Planting dogwood in the proper soil type keeps the tree healthy for flowering production.
    2. Plant the tree in a hole that is two to three times wider and the same depth as the root ball. Work equal parts of organic compost into the removed soil to increase the soil nutrient value and assist with water draining. A well-draining soil reduces tree stress that causes poor flower production and color.
    3. Set the tree in the planting hole and gently pack soil around the root ball. Apply a generous amount of water to the soil around the tree to remove air pockets from planting. Continue to apply water a 5-gallon bucket of water to the tree two to three times a week for the first month. This will stimulate root establishment for a healthy tree with pink blossoms.
    4. Apply a 3- to 4-inch layer of organic mulch over the root ball of the tree. Leave a 6-inch space between the trunk and start of mulch. Refresh the mulch each spring to help keep the soil moist for flower production and pink color.
    5. Fertilize the pink flowering dogwood each spring with a slow-release tree fertilizer. Mix the fertilizer into the mulch area over the root ball. A yearly fertilizer application works to keep the tree healthy and promotes flower production and pink blossoms.

Tips & Warnings

  • Water the pink flowering dogwood after planting using a slow drip method. Drill a 1/4 inch hole through the bottom edge of a 5-gallon bucket. Place the bucket under the tree and fill it with water. The water will slowly drip into the soil and absorb around the root ball.

  • Add ground rock sulfur to the soil before planting the dogwood tree if the pH is higher than 6.5. The proper soil pH promotes pink blossoms on the tree.
