Q: The slope in front of our house is too steep to grow grass. Is there an alternative? A: Shore juniper, which grows to a height of one foot and spreads four to five feet, is good for such a situation. The plant has fine texture, the gray-green needles are about half an inch long, it grows rapidly in full sun and will tolerate partial shade. Bar Harbor is another juniper well adapted as a ground cover. Q: We plan to plant some shrubs in front of our home. How far from the house should they be planted? A: Most shrubs should be at least four feet from the house, though small-growing ones can be as close as two feet. If larger ones are planted closer, it may be necessary to shear them regularly. Q: The apples from our trees don't last very long. How should they be stored? A: Most apples keep best at 30o to 32o F., with a relative humidity of 85 to 88 percent. McIntosh, Yellow Newton and Rhode Island Greening do best at 35o to 38o F. The average freezing point for most apples is 28o to 29o F. The apples should be cooled and stored as soon as possible after picking; the sooner it is done the longer the fruit will keep. Q: When is the best time to prune my Henri clematis? A: Henri produces blooms on the current year's growth, and should be cut down to about a foot from the ground in late winter or early spring. Clematis that produce their blooms on old wood should be pruned heavily every five or six years. Q: We had our big maple tree cut down. What is the best way to get rid of the stump? A: Stumps can be burned out, pulled out by a bulldozer or rotted out. One way to speed rotting is to cut the stump off close to the ground and cover it with about three inches of soil. Then apply abut half a pound of nitrogen at regular intervals. The nitrogen will increase the population and activity of bacteria and speed decay. They are active only when the temperature is between 50o and 90o F. Q: I'd like to have a putting green in the back yard for practicing my golf game. What kind of grass is best, one that can be used for the entire backyard? A: One of the best probably is Fylking Kentucky bluegrass. It can withstand mowing as low as half an inch. When cut this low, most grasses die back, become sparse, and weeds soon appear. Fylking can take it. Q: I want to transplant a young rose bush. When is the best time to do it? A: It can be done in late fall or early spring.
