mate rate of 5 pounds to 1,000 square feet, and water it in, a measure 
said to be effective for five years. Or lift the plants, wash the roots 
and plant in fresh ground. | 
Cutworms and slugs are destroyed by spraying with arsenate of 
lead, using slug bait, or dusting leaves with DDT. 
Red spider, the orange mite which sometimes devitalizes plants 
during excessively dry periods by feeding on the underside of leaves, 
can be controlled by thorough waterings, moving plants to more 
shade, dusting underside of leaves with micro-sulphur, or suffocating 
them by spraying underside of leaves with bill posters paste, 1 table- 
spoon to a gallon of water. ; 
If mice feed on your Primroses in the winter place rat poison in 
mouse holes or around plants before snow flies. 
Winter Care—All of the Primroses listed in this catalog have 
wintered in Quebec in below zero temperatures. They should receive 
the usual care given all perennials. In the absence of snow or ice 
evergreen boughs, cornstalks, or any material which admits light 
and air and yet breaks the force of drying winds may be placed over 
the plants when the ground is frozen. An early winter mulch of well 
rotted manure adds protection and absorbs the beat of heavy rains. 
Perhaps the simplest winter care, and the one used at Barnhaven, 
is thoroughly watering the plants with a gentle spray during snow- 
less, Ssub-freezing temperatures to coat them with ice, thereby re- 
ducing drying effects of high winds and frozen grounds. 
Every phase of Primrose culture in all sections of the United 
States and Canada is contained in the Quarterlies of the American 
Primrose Society. See ins
