What is a good commercial amendment to add to my clay soil (Knoxville, TN zone 7)? I cannot make compost fast enough to use with all my planting. Also, when I plant acid loving plants, should I be adding a specific acidic amendment right into the soil or spreading lime or Holly Tone on later?
Look for a bagged soils amendment called Clay Buster amendment, it is top notch for breaking up high clay soils. Test the Ph level of your soils first for the acid loving plants areas, then let that be your guide as to what needs to be done to bring the acid level into better balance. Go slow on adding anything to change the acidic level, it is easy to go overboard and create problems that are hard to correct.
