Lighting – Move plants closer or farther away from windows, or to even another room, depending on need.Use sheer curtains to admit better light. Avoid placing plants between a curtain and window.
Humidity – Fill a tray with pebbles and place your pots on top. Keep the pebbles damp but don’t let the water touch the drainage holes of the pots where it would be absorbed into the soil. Also group plants close together.
Circulation – Keep air lightly moving through the room with a ceiling fan; it will help dissipate environmental gases and fumes. Give your houseplants a day outside if weather permits.
Pruning – Snip off spent flower heads and withered or yellowed stems. Use sharp scissors when pruning. (leaving a plant with jagged edges is an invitation to disease.)
