Dumb cane inquiry

My Dumb Cane plant (dieffenbachia) has been growing in a plastic bucket of water for several months. Its ‘stem’ is so thick its like a green tree trunk. This ‘trunk’ is in a ‘u’ shape and has now started ‘branching out.’ Should I plant it in dirt and if so what kind?


Hi Cassandra,

You should definitely plant your dieffenbachia in some soil, any good potting soil will work. Avoid the cheap no name brands since they may have questionable things in the soil. The pot you use should have drip holes in the bottom so excess water can drain out and the pot should only be a few inches larger than the root ball of the plant. Using a pot that is too large or does not have drip holes allows the soil to stay wet too long , causes root rot, and the plant dies.

You can read all my care tips for a dieffenbachia in the Popular Houseplant section of the website.


Dieffenbachia plants are very poisonous and should be kept away from pets and children. Read more about common houseplants that are poisonous in Don’t Feed Me To Your Cat! A Guide to Poisonous Houseplants.
