PLANTING OUT OF DOORS 
THE cultivation of these bulbs is simplicity itself. Provided only that one 
starts with sound, firm bulbs — obtained from a thoroughly reliable source — 
failure is almost impossible. When planting out of doors the soil is prepared 
as for other flowers, by being well dug and fertilized. Even in unfertilized 
soil the bulbs will usually give good flowers and for the best results it pays to 
be generous in the matter of fertilizing, using bonemeal. Each year some 
additional plant food can be given right after planting and again just after 
flowering. The purpose of the latter application is to develop good strong 
bulbs for next season’s bloom. Good drainage is essential — particularly for 
Tulips. The depth to plant is about five inches. Planting is best done in 
September, October — and in some parts very well possible during early 
November. As all of the so-called Dutch bulbs are perfectly hardy, protec- 
tioning against frost is not essential, but many gardeners provide for a Winter 
covering after the ground freezes hard to prevent premature growth in the 
Spring and thus lessen the chance of injury from late frost. 
We agree there are larger and more colorful catalogues. 
You will agree that our bulbs are larger and wait till 
you see the flowers, so colorful, and all at the very best 
prices and delivered. 
Ask for special prices on larger quantities.
