When you are working in an area where a washer or nut can drop into a delicate assembly or be difficult to retrieve, use dental floss. Fasten one end of a long piece of floss to the part and the other end to something solid. When the parts are finally installed, the dental floss can either be cut off or, as in the case of a nut, it will come right off because it will be cut by the threading action.
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.
