Strawberry leaf-spot.—The most common and serious fungous disease of the strawberry; also called rust and leaf-blight. The leaves show spots which at first are of a deep purple color, but later enlarge and the center becomes gray or nearly white. The fungus passes the winter in the old diseased leaves that fall to the ground. In setting new plantations, remove all diseased leaves from the plants before they are taken to the field. Soon after growth begins, spray the newly set plants with bordeaux, 5-5-50. Make three or four additional sprayings during the season. The following spring, spray just before blossoming and again 10 to 14 days later. If the bed is to be fruited a second time, mow the plants and burn over the beds as soon as the fruit is gathered. Plant resistant varieties.

Tomato leaf-spot.—The distinguishing character of this disease is that it begins on the lower leaves and works towards the top, killing the foliage as it goes. It is controlled with difficulty because it is carried over winter in the diseased leaves and tops that fall to the ground. When setting out plants, pinch off all the lower leaves that touch the ground; also any leaves that show suspicious-looking dead-spots. The trouble often starts in the seed-bed. Spray plants very thoroughly with bordeaux, 5-5-50, beginning as soon as the plants are set out. Stake and tie up for greater convenience in spraying. Spray under side of the leaves. Spray every week or ten days.

CHAPTER VII
THE GROWING OF THE ORNAMENTAL PLANTS—THE CLASSES OF PLANTS, AND LISTS

In choosing the kinds of plants for the main grounds the gardener should carefully distinguish two categories,—those plants to compose the structural masses and design of the place, and those that are to be used for mere ornament. The chief merits to be sought in the former are good foliage, pleasing form and habit, shades of green, and color of winter twigs. The merits of the latter lie chiefly in flowers or colored foliage.

Each of these categories should be again divided. Of plants for the main design, there might be discussion of trees for a windbreak, of trees for shade; of shrubs for screens or heavy plantings, for the lighter side plantings, and for incidental masses about the buildings or on the lawn; and perhaps also of vines for porches and arbors, of evergreens, of hedges, and of the heavier herbaceous masses.

Plants used for mere embellishment or ornamentation may be ranged again into categories for permanent herbaceous borders, for display beds, ribbon edgings, annuals for temporary effects, foliage beds, plants for adding color and emphasis to the shrubbery masses, plants desired to be grown as single specimens or as curiosities, and plants for porch-boxes and window-gardens.

Having now briefly suggested the uses of the plants, we shall proceed to discuss them in reference to the making of home grounds. This chapter contains a brief consideration of:

and then it runs into nine sub-chapters, as follows:—
