Planting in clay soil
If you have clay soil and can't get plants to grow easily, try this...
When planting, dig hole and then fill the very bottom of the hole with gravel, place plant on top of gravel, then fill in with soil. The gravel will help with drainage and give the plant opportunity to take root.
Also, my husband swears that adding a tablespoon of regular table salt will help the plant thrive also. I'm not sure how that one works but it has always done wonders for my plants.
