double Acaulis should be lifted and washed free of soil, the crowns 
Separated, roots cut back with a sharp knife to about 4 inches, 
large leaves removed, and the divisions re-set in freshly dug and 
enriched soil. Dividing immediately after flowering or after seeding 
when new growth begins gives the finest flowers the following 
spring. Division in early fall is second best. Auriculas grow more 
Slowly and need less dividing. Juliaes may or may not be divided 
according to type. Keep all divisions well watered and choose a 
cloudy day when dividing, if possible. 
Asiatics, particularly Candelabras, should be divided every other 
year at least, with yearly division recommended. Divide after flow- 
ering, immediately after seeding or wait until early fall. Many: 
Asiatics (all Candelabras) lose their old root systems after seeding 
and are sustained during the Summer by very short, new roots 
beginning at the base of the crown barely below soil surface. Another 
reason for heavy summer watering. Should the center of the plant 
show signs of mushiness, dust with Botano de luxe. Hot, humid 
weather is often responsible for such rotting which can be con- 
trolled by regular precautionary dustings. 
Pests—Root weevils are controlled in the adult beetle stage from 
late spring to fall by placing Bug-Geta or other standard baits for 
the purpose beneath the foliage here and there throughout your 
plantings. Lead arsenate sprayed on the foliage and adjacent 
shrubbery several times during the late spring and summer kills 
all leaf-chewing insects. Should plants diminsh in size during winter 
and early spring, or appear sickly, perhaps it is the larvae (also 
known as grubs, or weevils) of the beetle eating the roots. Lift 
the attacked plants, wash roots clean and reset in new ground. If 
impossible to do this use Orthocide Soil Fumigant. It is reported 
that Lysol in combination with nicotine—a tablespoon of each to the 
gallon, two cups to the plant poured close around the crown—is 
effective. 
Cutworms and slugs are destroyed by Bug-Geta or other standard 
baits. 
Red Spider may attack when plants are insufficiently watered or 
during abnormally dry, hot periods. When present, leaves diminish 
and turn yellowish-green. Unless eradicated devitalization results. 
Effective new Red Spider sprays are listed on page 31. 
In late fall or early winter place Red Squill in any mole runs 
and under plants at intervals throughout the garden to poison the 
field mice. 
Winter Care—All of the Primroses listed in this catalog have win- 
tered in Quebec in below-zero temperatures. They should receive 
the usual care given all perennials. In the absence of snow (the best 
protection) ice can be produced as needed in freezing weather by a 
gentle spray from the garden hose. Heavy watering often bruises 
foliage at such times. Ice protects plants from drying and if ever- 
green boughs, corn stalks, excelsior or other airy material are at 
hand, these placed over the ice slow up the thaw. Boughs or other 
material are often sufficient.
