Dividing—About every two years, or whenever the plant grows into 
a crowded clump and flowers diminish, Polyanthus, single and 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 re- 
moved, the divisions re-set in freshly dug and organically 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. Julianas may or may not be divided according to type. Wood- 
land type Primulas need not be divided unless desired. Keep all divi- 
sions well watered and, if possible, choose a cloudy day for the oper- 
ation. 
Candelabras should be divided every other year at least immediate- 
ly after flowering or after seeding, otherwise not until early fall. They 
lose their old root systems after seeding and are sustaind for a period 
by very short new roots developing just below soil surface (another 
reason for frequent watering). Should the center of the plant show 
Signs of decay, use dust containing fermate and sulphur. Hot, humid 
weather is often responsible. This also applies to the Denticulatas but 
the Belled and other Asiatics need not be divided so often as they in- 
crease more Slowly and have different root behavior. 
Fungus Control in Seed Beds—Do not use pre-emergent fungicides 
on the seeds. After various tests with Primrose seeds, it has been 
found by others that Carco-X applied in the strength of 1/200 to seed 
flats after seeds are sown will inhibit the growth of bread mold and 
damp-off. (Getzum Products, Box 37-B, Sumner, Wash.) It is good 
practice to always use any chemical solution very sparingly and always 
sow seed very thinly. When dusting young seedlings with fungicides 
and insecticides (we use California Spray Chemical Corp. multi- 
purpose dust Botano de luxe) always use equal parts of unscented 
tale (from any drug store) mixed with the chemical as _ precaution 
against burn. 
Pests—Root weevils are controlled in the adult beetle stage from late 
spring to fall by placing an all-purpose bait beneath foliage here and 
there throughout your plantings. But should your plants diminish in 
size during the fall, winter and early spring, or appear sickly, this 
may be the sign that their larvae are feeding on the roots. Carco-X 
in 1/200 solution is recommended or Botano de luxe. Plants may have 
to iS lifted, washed clean and reset in good rooting medium, if very 
sick. 
Cutworms and slugs are destroyed by all-purpose baits. 
During abnormally dry, hot periods and for want of water, Red Spi- 
der may develop in the summer and is detected by yellowing and dim- 
inishing leaves. Ask your garden supply house for controls. 
_ in late fall or early winter it is good practice to place Red Squill 
in mole runs and under plants at intervals throughout the garden to 
poison field mice. 
_ Winter Care—AlI of the Primrose types listed in this catalog winter 
in Quebec in below-zero temperatures. In areas where sub-freezing 
temperatures are unaccompanied by snow, ice is good protection and 
is produced as needed by a gentle spray from the garden hose. If 
possible, put light airy mulching material over this. In mild climates 
or where temperatures are just under freezing no protection is neces- 
sary. Protection is mostly against freeze and thaw and against the 
blasting of flower-buds and defoliation of the evergreen types.
