Sand can reduce amount of de-icing product needed

The winter weather has been relatively warm so far, but eventually there will be snow and ice in our area. Follow directions on bags of ice melting product when salting slippery areas on walks. De-icing products absorb water from the air and can become unusable if it is not stored in a sealed container or bag.

Many people apply too much product, which can cause damage to pavement and adjacent plants. Consider using sand on slippery areas. Mixing a small amount of de-icing product in with sand can also be effective and minimizes the amount of product used. Calcium- or potassium-based products are less damaging to plants than sodium chloride products. Always shovel before spreading the de-icing material.

• Potted cyclamen plants from florists actively grow during the winter and prefer cool indoor conditions and a location with lots of bright indirect light. Water them only when the soil dries out and avoid splashing water on foliage. Remove faded flowers and their stems as soon as possible to keep the plants blooming and looking good.

• Pot up new amaryllis bulbs in wide, squat containers using a soilless growing medium. Allow the “shoulders” of the bulb to remain above medium; water well once and then allow the medium to dry out before watering again. Keep the pot away from direct sun, drafts and heating vents. As the stalk grows, rotate the pot for even growth. Most amaryllis send up the stalk and flowers first. After flowering, allow the stalk to yellow and wither before removing from the bulb. If you want to try to save the plant, continue to water it when leaves emerge. After May 15, take the plant outside to receive morning sun and fertilize regularly with a dilute 10-10-10 or 15-15-15 mix. Bring the bulb in before Oct. 15 for its resting period.
