A writer in the "London Journal of Horticulture" says "that a complete cure for the above disease may be found by taking one pound of flour of sulphur, one pound of slaked lime, and one gallon of rain water; mix well together, and boil twenty minutes; take off and strain; add one gallon more of water, and again boil twenty minutes, when the liquid will be a fine amber color; put in a jar and cork tight. When used, take one pint to sixteen gallons of rain water and syringe the vines, and it will not injure fruit or leaves."
Hoe frequently around newly planted trees. It is better than mulching with any material, as the fresh-stirred soil admits air and light, and absorbs the dew of every night. If you have no time to hoe, then mulch.
Shrubs that have done blooming should be at once headed back, in order to have them form a vigorous growth and prepare their flower buds for another season. Cut severely the strong growing shoots, lightly those more slender, and take out entirely all very small spray, leaving the plant in a cone or round-headed form, as your fancy may dictate.
