Water new shrubs once a week the first summer with 5 to l0 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.
Store your pool chemicals out of direct sunlight to prevent breakdown by UV rays.
Remember to clean or replace filters on furnaces once a month, or as needed.
If you don't have a soil moisture probe, some simple guidelines can help you decide when to water. Water when grass changes from a green to a grayish blue color, when grass leaves begin to roll, when the grass stays down after being walked on, or when you can't easily push a screwdriver down into the soil a half foot or so. Apply 1/4 in. of water and then check to see if the soil is wet down to 6 in. If it isn't, make another application just so the soil is moist, but not wet or sticky.
