When the weather is cold enough to freeze a hard crust on the soil, the bed should have its winter overcoat. This may be straw, hay, cornstalks, or leaves spread over the bed to the depth of six inches if the material is coarse; but if you use leaves, three inches will be enough, because the leaves lie close together and may smother out the frost that is in the ground and let the bulbs start. What we want is to keep them asleep until spring, because if they start too early the hard freezes of March and early April will spoil their beauty if the leaves or flowers are near or above the surface. Early in April the covering may be removed gradually and should all be off the beds before the leaves show above the ground. [Illustration: _Fig. 369. Simple designs for bulb beds._] Perhaps many of you cannot find a sandy place for your beds; if not, make your beds as has been told you, leaving the stones in the bottom of the bed for drainage. Then, when you are ready to set the bulb, place a large handful of sand where your bulb is to go and set your bulb on it; this will keep the water from standing around the bulb. Very good results may be obtained on heavy soil by this method. What kind of bulbs shall we put into these beds? Choose hyacinths, tulips, narcissus, or daffodils, with snowdrops or crocuses of various colors around the edge. If you use hyacinths you can have the national colors, red, white, and blue, or many shades of either color, as shown in the diagrams (Fig. 369). Of tulips you can have stars or ribbons of yellow, white, or crimson, or in fact almost any color except true blue. In narcissus, yellow, sulfur, and white are the colors. The little crocuses come in yellow, blue, white, and striped colors, and are in bloom and gone before the large flowers take your attention. Many other bulbs are fine for spring flowering; but as most of them are more difficult to grow and many of them rather expensive, I do not think we will discuss them now. Suppose we want a bed of red, white, and blue hyacinths (Fig. 369), and make it six feet in diameter: how many bulbs would you want? Now, hyacinths should be planted six inches apart each way, and the outside row should be at least three inches from the edge of the bed. You see you will want a little over one hundred bulbs, which, if one person had to buy them, would cost him a considerable sum; but if fifty or more boys and girls would club together it would be easy for everyone. If you want a bed of tulips, they should be planted four or five inches apart instead of six inches. So you will need more bulbs; but they are cheaper than hyacinths. The narcissus bulbs, being still smaller than tulips, may be planted three inches apart; and the little crocuses, the first flowers of spring, should touch one another, as should also the snowdrops.
