ARTIFICIAL WINTER 
We recommend that primula seed be given a 
cold treatment before planting in order to assure 
prompt germination. Here’s a simple and effec- 
tive method: 
Put a few drop of water in the packet contain- 
ing the seed and shake gently until the seeds 
are coated with moisture; then freeze in the ic 
compartment of a household refrigerator for one 
week; remove and thaw for 24 hours; replace in 
the ice compartment for 24 hours; remove, thaw 
and sow.

Suggestions for 
Primula Growers 
February, March and April are the popular 
months for sowing primroses, because it aids 
germination to expose the flats or pots to alter- 
nate freezing and thawing, for a week or more, 
before removing them to a temperature of from 
60° to 70° for germination. Spring planted seed 
usually germinates in about 3 weeks. Freshly 
harvested seed, sowed in July, August or Sep- 
tember usually germinates in from a week to 
ten days. Except Asiatics, which do not ger- 
mincte recdily in warm weather. 
The Colossal Mixed strain of Polyanithus 
Primulas offers a great advantage to growers. 
Blooms are produced from ten days to two 
weeks earlier than other strains, and this earli- 
ness combined with the unusually large flo- 
rets means a lot in marketing blooming plants.
