HOME (Indoor plants and activities)
Check houseplant leaves for brown, dry edges, which indicates too little relative humidity in the house. Increase humidity by running a humidifier, grouping plants or using pebble trays.
Extend the lives of holiday plants such as poinsettias and Christmas cactus by placing them in a cool, brightly lit area that is free from warm or cold drafts.
Houseplants may not receive adequate light because days are short and gloomy. Move plants closer to windows, but avoid placing foliage against cold glass panes. Artificial lighting may be helpful.
