Dividing—About every two years, or whenever the plant grows in- 
to a crowded clump and flowers diminish, Polyanthus, Acaulis and 
Double Primroses 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, 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 whether they are inclined to 
more bunching than spreading. Sieboldis need not be divided unless 
desired. Keep all divisions well watered and, if possible, choose a 
cool day for the operation. 
Candelabras should be divided every other year, at least, immedi- 
atelv after flowering or after seeding, otherwise wait until early fall. 
They lose their old root Systems after seeding and for a period dur- 
ing the summer have only very short roots barely below soil surface 
and therefore in need of plenty of water and mulching. (Should the 
center of the plant show signs of decay during hot, humid weather, 
use a dust containing fermate and sulphur.) This also applies to the 
Denticulatas, but the Belled and other Asiatics need not be divided 
so often. 
Seeding—With every seed order we send a leaflet which outlines 
quick and easy methods of germination which will aid in the grow- 
ing of other perennials, seeding mediums, safe and sure pest and 
fungus controls and transplanting information. 
Pests—Slugs and cutworms are controlled by the use of all-purpose 
baits scattered among your plants. 
This same bait, placed beneath the leaves, will control, to large 
extent, the beetle responsible for root weevils. Signs of root weevil, 
if any, appear in the fall, winter and early spring and can be noted 
in the diminished size of plant and general sickly appearance. Use 
Carco-X in 1//200 solution (write Getzum Products, Box 37-B, Sum- 
ner, Wash.) pouring a cupful or two around the crown of the plant 
So that it percolates through the roots killing the larvae feeding 
there. If plants seem far gone, lift, wash roots clean and reset in good 
rooting medium. 
During very dry, hot periods and for want of sufficient water, Red 
Spider may develop and is detected by yellowing and diminishing 
leaves. Use California Spray Chemical Company’s Isotox Garden 
Spray, or ask your garden supply store for recommendations. 
In late fall or early winter, before snow, 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—All of the primrose types listed in this catalog win- 
ter in Quebec in below-zero temperatures, but with good snow cov- 
erage. In areas where Sub-freezing temperatures are unaccompanied 
by snow, mulching between plants with manure is excellent, covered 
over all by evergreen boughs. Ice is good protection (gently spray 
plants with hose) but light, airy mulch of boughs or other materials 
over the iced plants is best to retard thaw and protect from sun. 
In mild climates where temperatures are just under freezing no pro- 
tection is needed but WHEN GROWTH IN WINTER IS UNRE- 
TARDED BY HEAVY FROSTS, PROTECT QUICKLY WITH 
BOUGHS OR OTHER MATERIAL SHOULD TEMPERATURES 
SUDDENLY DROP BELOW FREEZING.
