through a piece of mosquito netting, beirg careful not to have the covering over four times the thickness of the 
seed. Depending on conditions, it will take from ten to thirty days for all the seeds to germinate. After the 
second set of leaves has developed, the seedlings should be transplanted into another shallow box, spacing them 
two inches apart each way. : 
During the late spring and summer months, perennial seed may be started in a small seed bed outdoors. 
Note: That when seeds are sown outdoors they 
should be covered more deeply than if sown indoors 
or under glass. 
Ask for our leaflet, “‘A Perennial Garden—From Seed.” 
Cover to fully 3 times the diameter of the seed. 
PREPARATION OF THE SOIL FOR BEST 
RESULTS WITH FLOWERS 
The principal object to keep in mind particularly for the successful 
cultivation of annual flowers, is that the plants complete their life cycle 
in the comparatively short period of from three to four months time. 
This naturally leads to the conclusion that although the soil should be 
well drained, the mechanical condition should be such as to permit the 
retention of a certain amount of moisture, in order to dissolve the plant 
foods in the soil, because plants must subsist entirely upon a liquid 
diet. They are unable to absorb any food before it has first been dis- 
solved. 
In order that the soil will be in proper mechanical condition, it must 
contain an abundance of humus. This can be supplied either through 
the medium of rotted stable manure, Peat Moss (see page i40) or 
Hyper Humus (see page 139). The humus material should be spaded 
in and thoroughly incorporated with the soil. For Annuals, the soil 
should be dug to a depth of 8 or 9 inches and for Perennials, to a depth 
of 12 inches or more. Plant food should be applied at the rate of 10 
lbs. to 200 square feet. The Henderson Garden Fertilizer (described 
on page 139) is a well balanced plant food which contains all of the 
elements required for the successful growth of plants. 
The question is frequently raised regarding the soil preferences of 
various plants. Most garden soils, especially those that are inclined 
to be sandy, are either neutral or slightly acid. The great majority 
of garden flowers, especially the Annuals, prefer this type of soil. 
Those that in their natural habitat are found in woodlands, as well as 
a few others including Daisies, Lupines and Salvia, prefer an acid 
soil. Where the soil is found to be over-acid, it can be corrected with 
an application of Hydrated Lime (see page 140), or where it is necessary 
to increase the acidity of the soil, this can be accomplished by applying 
Aluminum Sulphate (see page 140). 
A DOZEN ANNUAL FLOWERS 
that will grow almost anywhere 
The following have been selected as being a sure fire group suitable 
for a beginner’s or a child’s garden. All of these will grow in poor 
soil; all that they demand is an adequate amount of moisture and direct 
sunlight over the major part of the day. :
