How can I successfully cultivate mushrooms growing in a planter?

To successfully cultivate mushrooms in a planter, you need to create the right environment with proper moisture, temperature, and light conditions. Use a suitable substrate like compost or sawdust, and inoculate it with mushroom spores. Keep the planter in a dark, humid place and mist it regularly. Harvest the mushrooms when they are ready by gently twisting them off the substrate.
