It's possible to retrofit insulation into an existing home, even without the access provided by remodeling. The choices, however, are much more limited. There are some retrofit insulation products that are designed for minimal disruption to finished wall or ceiling surfaces. Significant gains in R-value, however, may mean hiring a professional to assess your needs and devise an energy savings plan. Small or large, insulation projects can yield substantial gains in R-value and in comfort.
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.
