When installing in-wall speakers, use a drywall saw to cut the hole. A utility knife will make the cleanest cuts in drywall, but a utility knife can be difficult to control by a non-expert. Electric rotary saws make cutting drywall physically easy, but they too can be difficult to control. A simple, inexpensive drywall saw (about $10 at your local hardware store) is the best bet for beginners. The speaker's frame will cover up any rough edges.
Keep an extra tool set in your car or truck. Think of it as an insurance policy against road emergencies. You’ll be glad they’re there when you need them.
Gas logs release a lot of water vapor when they are burning. You should be wary of mold and mildew, especially if you have asthma and respiratory problems, when using them for longer than a few hours. A CO detector is a great gas-log accessory. You can find one in many home-improvement and mass chain stores
Water new shrubs once a week the first summer with 5 to 10 gallons of water for each depending on the size of the bush. Take care to get the water under any mulch, which absorbs a great deal of moisture and robs the soil below. Pour water right down the stems so it goes into the root ball, and does not run off on the ground. During very hot sunny days, spray the tops and water lightly in addition to the weekly deep watering. Do not fertilize the first year, except possibly for half strength liquid fertilizer at planting time, or plant rooting hormone additives one can use. Fertilize normally the second year in the spring.
