Suggestions please - one area does not drain
I have a planting bed which has Redbud, Veronica, Weigela, Cottoneaster, Rhaphiolepis and more. They are all doing well yet when I tried to plant Mexican Orange (x2) it shriveld up brown and crispy.
I finally decided to investigate. I think there may have been a problem with the drip and it got too much water. I then decided to do a drainage test. My hole was only 6" deep but 14" wide. After 5 hours the first fill still has 2" in it.
The native soil is clay but large amounts of ammendment and compost were brought in to create this bed. Any suggestions?
