NICHOLS, L.P. 1984. Thirteen flowering crabapples. Am. Nurseryman 159(9): 26-28, 30-31.

Crabapples provide a glory of beauty with their spring blooms. Yet the flowering lasts only a short time. When selecting crabapples, one must look also at their form, the color and texture of their foliage, and their fall show of fruit. I have chosen the following baker’s dozen of trees with this in mind. In 1982, I submitted a list of my 11 favorite flowering crabapples (“Eleven Excellent Crab Apples,” American Nurseryman, October 1, page 90). They are still fine trees. The following list might be considered a supplement. They are ‘Bob White,’ ‘Donald Wyman,’ ‘Liset,’ ‘Mary Potter,’ ‘Ormiston Roy,’ ‘Profusion,’ ‘Red Baron,’ Redbud Crabapple, Malus sargentii, ‘Tina,’ ‘Sentinel,’ ‘Sugar Tyme,’ and ‘White Cascade.’

TINGA, J.H. and R. BRAY. 1984. Place trees properly for a cooler house. Am. Nurseryman 159(6): 155-157.

In the sunbelt, air conditioning bills are going up every year. Planting vegetation can decrease this buildup. This article deals with findings from a five-year experiment on the effect of planting trees and shrubs close to a 1½-story Cape Cod house. In our landscape, we are chiefly concerned with blocking the sun’s rays from coming through the windows and with shading the walls and roof. These heat factors should be considered in placing trees and shrubs in any landscape. The southwest corner of the house is the most critical area to cool. To shield this critical area, tall deciduous shade trees could be placed near the drip line of the house on the south and west sides.
