On the Sowing of Flower Seeds - The Maryland Farmer and Mechanic. June 1, 1864

    In order to be successful in raising flowers from seeds, it will be necessary to bear in mind that the smaller the seed the less deeply should it be covered with earth. Some seeds are so small that they require only to be sprinkled over the ground and gently pressed into the soil, and should the weather prove very dry, a thin layer of damp moss ought to be placed over them til they germinate, when care must be taken to have it removed. There are few seeds that require such extreme attention.

    Small seed such as Petunia, Portulacca, &c sow about one-eight (sic) of an inch in depth; those of larger sizes as Mignonette, Sweet Alyssum, &c, about one quarter of an inch in depth; still larger as Balsam, Morning Glory, &c, three quarters off an inch in depth; and seeds of the largest size as Nasturtium, Lupine, &c, fully one inch in depth. They must be covered with finely pulverized soil, or leaf mold slightly pressed down, and should be kept moderately moist by shading or slightly sprinkling of water, until they make their appearance. Tall varieties should be neatly staked to prevent injury from wind or rain.
