Monstera
Oceana
Water from the roots and the light, not from a calendar. Wet mix kills more Monsteras than drought.

A fixed watering schedule fails because pot, mix, and light change every week.
Wait for the top to dry, lift the pot, look at the aerial roots. Water until it leaves the drainage holes, then empty the saucer.
Growth season asks for more frequency than dark months. Variegated plants dry slower than green ones in the same pot — white tissue transpires less.
