Robson's Perennial 
Perennials are those accommodating plants that when once planted come up year after year. 
require some care and frequent dividing and replanting. 
They do 
In the small perennial border it is often impossible to have a large enough variety of perennials to keep the 
garden gay with color, because perennials have their period of bloom. Therefore, it is wise to have a definite 
spot where annuals can be raised and moved to the perennial border to supplement the color display. 
In preparing a perennial flower bed or border for a new planting, the soil should be well supplied with humus 
by spading % to | bushel of rotted manure or peat moss into the soil. 
Growing your own perennials from seed is an enjoyable and economical pastime if a few rules are followed. 
1. Sow all perennial seed as soon as possible after June Ist. 
2. Acoldframe is preferable as a seedbed; however, seed can be sown in the garden. 
3. Seeds should be sown in rows 6 inches apart and covered twice their diameter by sifting soil over them. 
Press the soil firmly with a board after sowing. 
4. Cover the entire bed with burlap or cheesecloth. All watering should be done on the burlap. 
5. As soon as the seedlings appear remove the covering and put a shading about a foot from the ground over 
them—a lath shade is very satisfactory. This will keep off the scorching sunlight. 
Never let the seedbed dry out. 
6. Scratch in a small amount of plant food between the rows of seedlings when they are about 6 weeks old. 
The shading can be removed then on a cloudy or rainy day. 
7. Late in August the plants can be transplanted to their permanent positions.
