Hard Clay Soil
I live on the hot/dry side of San Diego and have an over abundance of clay soil. We had our yard landscaped last summer but I would like to add some fill-in plants in some places. The problem is the soil in my empty spots is rock hard! (We've had our fair share of 90degree days this summer).
When we had the yard landscaped they removed a great deal of the existing soil and added amendment and compost for the plantings. I did the same for a 5x3 area this weekend and it was truly back-breaking work!
Any tips on a less agonizing way to go about this?
