Bulbs like the snowdrop and crocus are planted several or a dozen in a pot and buried, or treated like hyacinths; but they are very sensitive to heat, and require only to be given the light when they have started to grow, without any forcing. Forty to 45° will be as warm as they ever need be kept. See the article on [Bulbs]; also, the advice given for the various plants under their respective names.
Pests.—Window-Garden pests are discussed under [Insects].
Winter-killing is induced by a late fall growth, and also by a dry, unprotected soil. All tender woody plants should be well ripened before cold weather comes: cease tillage early: do not apply stimulating manures late in the season. Mulch all tender or half hardy plants ([see Mulch]). Even hardy plants are benefited by a mulch. When possible, it is better to bend plants to the ground and cover them than to wrap them up as they stand; but this cannot be done with tall or stiff subjects. Wrapping in straw or burlaps affords excellent protection, but it is possible to wrap too heavily. A barrel, less the heads, may be set over small plants and then filled with leaves or other loose litter; or a cylinder of wire chicken-screen may be substituted for the barrel. Remove the protection in the spring before the buds start. See that mice do not nest in the barrel or in the mulch.
Zinnia. Showy hardy annuals. The old formal type of Zinnias has given place to a race of freer forms which are excellent plants either for color effect or for cutting. The colors have been varied and brightened, the flowers doubled and the plants dwarfed. Seed should be sown in a hotbed or house in March, transplanted once at least before planting out, and set in well enriched soil. Or, the seed may be sown where the plants are to grow. The tall varieties (3 feet) should stand 18 to 24 inches apart. These are best for masses at a distance.
