Dieffenbachia maculata is a tropical evergreen perennial in the arum family (Araceae), grown as a foliage pianta di appartamento; its sap contains irritant ossalato di calcio.
Tolerates low to medium indirect light well, making it one of the more forgiving foliage plants for less bright interiors. luce indiretta intensa produces faster growth and more vivid variegation. evitare il sole diretto, which scorches the large leaves.
Allow the top 3-4 cm of soil to dry tra un'innaffiatura e l'altra, then innaffiare abbondantemente. Reduce frequency in winter. Dieffenbachia tolerates occasional drought better than soggy soil - overwatering causes yellowing lower leaves and root rot.
Use a ben drenante, peat-based miscela di terriccio with added perlite (roughly 3:1). Good drainage is important: the thick stems store water and are prone to rot if the root zone stays wet.
Optimal range 18-27 °C; minimum 12 °C. Avoid cold drafts - sudden cold causes drooping and leaf discolouration. Medium humidity is adequate, but umidità piu elevata promotes larger, lusher growth.
concimare mensilmente during primavera e estate with a equilibrato concime liquido at a mezza concentrazione. No fertilizing in autumn or winter. Avoid high-nitrogen formulas, which encourage leggy growth.
⚠️ CAUTION: Dieffenbachia sap contains ossalato di calcio crystals - ALWAYS wear gloves when pruning or repotting. Contact with eyes or mouth causes intense burning and temporary swelling of the tongue and throat (hence the common name 'Dumb Cane'). Keep away from children and pets. Prune the stem back in spring to encourage branching if the plant becomes leggy. The cut stem can be used for propagazione.
The most common method for propagating Dieffenbachia is by divisione. This involves separating the stems during repotting. Ensure the parent plant is healthy before proceeding.
Some Dieffenbachia species can be propagated by stem cuttings.
