TODAY'S GARDEN
January 2018

For information on how to care for poinsettias please see www.ext.colostate.edu/ptlk/1325.html.
 
Christmas cactus plants prefer bright, indirect sunlight, and they require light to moderate water.  Fertilize plants every 7-10 days with a liquid fertilizer while they are growing and not in bloom.
 
Colorado's low humidity combined with heat from the furnace can rapidly dry out houseplants in winter.  Check plants regularly to see if they need water.  On the other hand, avoid over-watering plants.  Too much water can lead to plant diseases or pests such as fungus gnats. 
 
Trees, shrubs and lawns are likely to require winter watering this month.  If there has been little or no snow for four to six weeks, water plants when the ground isn’t frozen and the temperature is above 40 degrees F.
 
Dry winds, fluctuating temperatures and insufficient water can cause the needles of evergreens to turn brown in winter.  To prevent winter injury, water plants monthly and place mulch over the root zone of plants.
 
Cut off branches from your Christmas tree and use them to cover flower beds during the winter.  Like mulch, the branches limit the effects of freeze/thaw cycles.
 
Keep living Christmas trees well watered, both before and after planting.  They may also benefit from being sprayed with a product such as Wilt-pruf to prevent evaporation of needed moisture.
