Let me tell you a story
When I was about 5 years old I spent a lot of time with a neighbor couple. They had no children. They had a yard with many plants. This yard was my first memory of clock vine and dutchman's pipe vine.
When he planted any thing he used the method of filling the hole full of water. He then set the plant in the hole and filled it again. Then he used a hoe to backfill the soil while the water was till in the hole. He gently stepped on the soil to get any air pockets out.
Monday I did this with a 3 gallon potted beauty berry. It took me several hours to get the hole dug. The soil was like concrete and had numerous rocks in it.
As of yet the plant has not even wilted.
This was a bird planted beauty berry that I dug up and potted in the spring.
