Gardening

The mushroom is just the fruiting body of the mushroom, which is actually the strands of a fungus growing underground. And that fungus has found a suitable place to grow, with the conditions that it prefers. Trying to duplicate the proper conditions will be next to impossible. You will probably not hurt the mycelium, which is the threadlike strands that are underground, by using the planter. The mycelium are probably associated with tree roots or dead wood underground, and you will not damage that. Just look for them in that same area every year, and enjoy.

If you have more questions, just ask, but I don't want to do a dissertation on fungi here. Just know that the morel that you see is just like an apple on a tree---you can't transplant it have grow an apple tree, it is just a fruit of a much larger organism.
