IN SPRING ... PLANTS ARE 
SET OUT IN COLD FRAMES 
FOR THREE TO FOUR WEEKS 
Here we see young plants of STOKES 
ASTERS going into frames to harden up 
for 3 to 4 weeks growth under sash. 
Of course, this is just one variety in the 
thousands of perennials and shrubs which 
must be set out. The photo below, taken 
ona rainy and cold day in March, shows 
row after row of propagating frames. 
CONSTANT and ALERT 
SUPERVISION 
FOLLOWS EVERY STEP 
Specialists vigilantly watch every opera- 
tion from the preparation of cuttings and 
potting in the greenhouse to the harden- 
ing-off in outdoor cold frames. The vari- 
ous departments of field growing are 
further sub-divided into the specialized 
growing of. perennials, Roses, bulbs, 
shrubs and trees. 
Shown here with Mr. J. J. Grullemans, 
President of Wayside, is the Propagating 
Supervisor, inspecting young Oriental 
Poppies which have been hardened-off in 
cold frames before being transferred to 
the field.
