Wild dogwood trees are deciduous trees that live under the canopy of forests. They bloom in spring with gorgeous flowers in shades of pink or white. The wild dogwood tree needs to be grown in an environment as close to its natural habitat as possible: dappled shade, cool temperatures and lots of leafy-loam to grow in. The United States National Arboretum suggests that you check with your county extension for information on the right dogwood tree to grow in your area.
Choose a spot in the garden that receives morning sun and dappled shade later in the day. It shouldn't be too close to structures or other large trees so that the dogwood will have adequate air circulation.
Remove the pulp from the seed. This may require a bit of gentle scrubbing under running water. Be sure to remove all of the pulp, as anything remaining on the seed will rot and cause the seed to do so as well.
Moisten a handful of sphagnum peat moss and wrap the seed in it. Place it in a plastic sandwich bag and seal the bag. Place the bag in the refrigerator for three months, checking it periodically to make sure that the moss is still moist.
Fill the planting pot with compost and perlite. Water it well, allowing the water to drain from the bottom of the pot.
Remove the seed from the bag and plant it, 1/2 inch deep, into the planting pot.
Place the pot in an area in which it will receive bright light, but not direct sun. Keep the soil moist, but not soggy.
Wait until after the last frost date for your area and begin the hardening off process. This will acclimate the tender sapling to the outdoors. Take the pot outside for one hour on the first day, and then gradually increase the amount of time the sapling is left outside, over the course of a week or two.
Prepare the planting bed for the dogwood tree. Dig up the soil to a depth of 12 inches, crushing any large clods of dirt with the shovel. Add a 4-inch layer of compost and mix it well with the existing soil.
Dig a hole the same depth as the pot in which the seedling is growing. Place the roots of the dogwood sapling into the hole and backfill, tamping down lightly on the soil around the base of the tree.
