Dogwood trees require good drainage
Posted on Sunday, May 11, 2008
Question: Will a dogwood tree grow in rocky soil ?
Answer: If you take a drive outside of town, you will see dogwood happily growing in the woods in rocky soil. Rocky soil is not good for vegetable gardens, but it is not all bad. Rocks - we are not speaking of boulders - help to drain our clay soil. Dogwood requires good drainage.
It is best to plant a dogwood tree raised from seed or cutting. Use the guidelines that have been given for any container-grown tree. Dig a hole twice the size of the container but not any deeper. Place the tree in the hole and fill it back with the same soil taken from the hole. Water to settle the soil, and then again once a week through the summer. Any rocks that show up in the process can be placed on top to help keep moisture in the soil.
Question: We have found many bricks that have been covered up in a place where we plan to put a vegetable garden. Is there any toxic material in old bricks ?
Answer: Old bricks are formed from clay and water. They are dried and then fired. No toxic material is used. We suggest that you dig them up, rinse them off and use them for an edging.
