“I experimented with 4 different soils with 3 “big name” seeds and 1 seedsman Blueberry auto. For the seedsman blueberry I just dug a hole, put some store bought compost in the bottom and put the dirt back in with the seed. Others got potting soil paralite etc. the seedsman auto is double the size took LST and two toppings no problems. Just dirt and water. Very happy.”
