Wildgrower,
I have bought morel mycelium blocks from companies before and I had no luck with them. You want to grow some areas for new morel growth try this
Pick your morel mushrooms in the wild like always. Bring them home and soak them in a clean sink full of cool temp UNSALTED water from the faucet. If you have unclorinated water available that is even better. After you have soaked the morels for about 10 minutes remove the morels from the water and let them drain morels on some paper towels.
Now take the morel \"soak\" water that is in your sing and get it into a steralized container. I use a rinsed out plastic gallon milk jug. Put in all the bits and pieces or what ever is in the sink soak water into the milk jug and put the cap on then put it in the refrigerator.
Now within the next 2 to 3 days take that morel spore water out in the woods and pour it within the drip line of an Elm, Poplar, Ash, Hickory or any Apple trees that you have.
It is possible that within a 2 or 3 year period from the time you pour the water as I have described, a new patch of morels will grow there.
It doesn't work all the time but it does work often.
This is the only way I know of to grow morel mushrooms.
