Here are some tips for winter gardening!
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.
Because growth slows or stops in winter months, most plants will require less water and little, if any, fertilizer.
If you are forcing bulbs for the holidays, bring them into warmer temperatures after they have been sufficiently precooled. Bulbs require a chilling period of about 10 to 12 weeks at 40 degrees F to initiate flower buds and establish root growth. Precooled bulbs are available from many garden suppliers, if you did not get yours cooled in time. Then provide two to four weeks of warm temperature (60 F), bright light and moderately moist soil to bring on flowers.
Evergreens, except pines and spruce, can be trimmed now for a fresh supply of holiday greenery even after Christmas has passed.
