I've read a lot about changing the soil in container plants. But I have a lot of conceptual problems with this, not that I don't want to do it. They seem like very stupid questions, but they are very real to me!
1) How do I do that without disturbing the roots? If its a fairly big plants, like a dwarf Meyers lemon, I can imagine only changing the soil at the top, above the roots. For smaller plants, I can imagine taking the whole plant out and changing the soil, but bigger container plants?
2) What do I do with the used up container soil? If I keep dumping used soil in my yard, then after many years, am I not changing the level and grading at the side of my yard, and wouldn't that be irresponsible? Or do I put them in a garbage bag and throw them out like garbage??
Thank you for helping a failing container gardener who is still hoping to succeed one of these days.......
