Q: Some of the grass in my lawn is dying. My neighbor says I need to spray for chinch bugs. Is there a way for me to determine whether it is necessary ? A: Chinch bugs can be bad at this time of the year. They feed on the roots and are usually not noticeable. Remove the bottom from a coffee can, shove the cylinder into the damaged grass and fill it with water. Check after 5 or 10 minutes to see if tiny red and white chinch bugs are floating in the water. If spraying is necessary, Spectracide is one of the best materials to use. Q: I had fuschias growing outdoors last summer in pots. When it started to get cold I brought them indoors. They Kept on blooming, but stopped in December and haven't bloomed since. What would cause this ? A: Fuschias are long-day plants, needing 12 hours or more of light for flowering. As teh days get shorter in November and December they stop blooming. Q: How effective are windbreaks in reducing the amount of energy needed to heat a home ? A: Studies indicate that fuel costs can be reduced 10 to 30 percent, depending on your particular situation. Dense windbreaks can reduce wind velocity 75 to 80 percent, and wind or air movement can account for up to one-third of the heat loss from a building.
