Grow dieffenbachia in a relatively warm, humid spot with plenty of light. Dieffenbachia will tolerate low-light spots, as well. If the leaves develop brown tips or edges, the air may be too dry. Remedy this by relocating your dieffenbachia to a well-lit bathroom (or other humid spot), grouping it with other houseplants (which release moisture into the air as they breathe), or set it on a pebble-filled tray of water, so the bottom of the pot rests on the pebbles, above the water to keep the roots from rotting.
4" plants fit well into all of our 4" pottery.
*Plant and Pottery purchases can be planted for you before pickup or make it into a 'plant at home kit' by adding a soil bag and moss/rocks to purchase.
