Perennial flowers are best used to form hardy borders, using low facers in 
front and tall plants at the back with intermediates between. To prevent 
the whole border from crowding and disorder, cut off the dead flowers before 
they go to seed. Against heavy rains and winds, they should be supported or 
staked and tied loosely. Adjusto ring stakes are good for certain types and 
tall Dahlia stakes for others; various lengths are needed for plants of different 
heights so stakes are not conspicuous. Use a light mulch of leaves in fall. 
To have large plants, perennial seeds are best sown in May, June, and 
July, unless otherwise noted. Forget-me-nots, English Daisies, Hollyhocks, 
Sweet William, and Pansies are best sown in August, in order to have plants 
not too large for handling. Large seeds should be sown in rows in flats or 
coldframes and lightly covered with sand or fine soil to the depth of twice 
their diameter. Cover fine seeds with a piece of burlap but no soil. Shade on 
a sunny day and transplant when two leaves occur, 3 to 5 inches apart. In 
some cases seedlings cannot be safely transplanted but in these cases thinning 
must be done until plants are separated. No ventilation, too much shade, 
and crowding cause “damping off,” a disease very destructive to young 
seedlings. To prevent this, use Ansul Dust. Water thoroughly with fine spray.

Wintering over Perennials. After the ground is frozen— 
not before—cover your perennial borders with 6 inches of 
dead leaves. This keeps the frost in the ground until spring 
comes and prevents alternate freezing and thawing through¬ 
out winter, which causes the ground to heave, resulting in 
the loss of plants.
