Plants enliven our living spaces, providing color, fragrance and improving the air quality. Whether you grow seasonal flowering plants during the winter months or evergreen tropical foliage plants year-round, proper care ensures they remain attractive. One of the most common causes of potted plant death is improper watering. This is especially true for evergreen plants in winter because their watering needs change as the days become shorter.

• Evergreen plants typically become semi-dormant in winter, necessitating less frequent watering since their growth has slowed dramatically. Reduce watering slightly until the plants exhibit a flush of new growth in the spring. The exception is plants that primarily flower during the winter.

• Feel the soil before you water. Most plants need water when the top inch of soil feels dry, but before the soil dries completely throughout the root zone.

• Empty the drip tray beneath the pot after watering. The soil reabsorbs the water sitting in the tree otherwise, which results in soggy soil and root rot. Remove the decorative foil or plastic covers from holiday plant pots during watering so the coverings don't retain water.

• Avoid wetting the foliage and flowers. Water-soaked leaves and blossoms are more likely to suffer fungal infections and mildew. Pour the water directly on the soil instead of sprinkling it on from above.

• Don't over water. Over watering is the primary cause of houseplant death. Plants that loose both new and old leaves, develop mushy stems or roots, or become moldy are suffering from over watering. Allow the soil to dry almost completely before you resume proper irrigation.
