Went and put out some plants this week. So I dug some holes to put the plants in, pretty good spot, but underneath about 6" - 8" of soil there was lots of rock. I'm not sure if it was solid rock for the whole area or just chunks, but I was wondering if my plants have a chance of surviving in those conditions? Will the roots have room to grow? I'm going back out again this weekend so if the plants wont grow well there I'll have to go find a new area. Thanks.
