WHEN PLANTS APPEAR TOO THICKLY IN THE ROWS, TRANSPLANT

A WELL-CONSTRUCTED HOTBED

Having constructed the pit, fill it with fresh manure from the horse-stable—that from young, grain-fed stock being best. It must be perfectly fresh, gathered from the stalls in the morning, and should be mixed with a quantity of litter—long straw or leaves. This serves as fuel, insuring a continuous heat. Without it the heat germinated by the manure would quickly die out and the bed become cold. Throw the manure loosely into the frame, close the sash and wait for fermentation or heating. This should take place in from twelve to twenty-four hours; if longer than that it will be as well to throw out the manure and begin again, making sure this time that the manure is absolutely fresh. When the thermometer by rising to 100 or more degrees shows that fermentation is well under way, the manure should be well tramped down, as level and smooth as possible. Over this place a couple of inches of fine, old, well-rotted manure. This will afford nourishment for the young plants should they make sufficient growth to need it, or on account of stress of weather be detained in the hotbed longer than expected. If this is not supplied the tender roots of the plants are apt to go in search of the crude manure in the bottom of the hotbed, and be injured by contact with it. When plants that have come up thrifty suddenly turn yellow and look as if they had been scalded, though sufficiently protected from the sun, it is probable that their roots have been burned by the manure. This may be determined by digging down to the roots. If they have reached the manure the cause is evident; other plants in the same beds, with shallower roots, it will be observed, are not affected in the same way. As this is not likely to happen until the plants have made considerable growth the season will probably be enough advanced to permit of planting out, especially with protection at night, or they may be transplanted into the cold-frame until the weather is warm. Such mishaps seldom occur, but when they do, they must be met promptly. Few plants will make over four inches of roots before transplanting, and when they reach the old manure they usually spread out without going deeper.

To return to the construction of the hotbed: Cover the manure with four inches of rich, fine loam, free from rough lumps and stone; it would better be put through a sand-or coal-sieve if not mellow and fine. Make as level as possible, and place a thermometer in the soil to register the temperature. When it has risen to 90 degrees or above, and then fallen to 75 or 70 degrees, the seed may be sown.

In planting seed it is best to use narrow strips of wood to separate the different varieties. This prevents mixing and running together when watered. It is impossible to distinguish between different varieties of Asters, Ageratums and Pansies once they have become mixed. Where one lives within reach of a box factory narrow strips of wood—admirable for this purpose—of uniform width and very thin, may be readily obtained. It is best to begin at the upper right-hand corner with seeds that require the most time to germinate, labelling each section plainly with name, date and the period of germination.

Flowers that make the tallest growth may be placed against the back with advantage—as Cobæa scandens, Ricinus, the Dolichos, Cosmos, and the like; giving them the advantage of the extra light and keeping them from withholding the light from the plants in front of them.

Coarse seeds should be planted in drills and covered to twice their depth. A furrow may be scratched with a sharp stick from an eighth to a half-inch deep, and the seed sown thinly in it, the earth being replaced and pressed firmly down with a piece of wood. This is important, as it brings the seed in close contact with the earth, and the tiny sprout can lay hold of it at once when germination takes place. Many seeds of weak germinating power are lost when sown in loose, coarse soil by failure to obtain immediate contact with the nourishment contained in it.

Fine seeds like Petunias, Nicotianas and Ageratums must be sown broadcast in little squares reserved for them. Sow on the surface, press into the soil with a piece of board and merely sift fine sand over.

A piece of thin wood eight or ten inches long and four or five inches wide, with a handle on one side, will be found very useful to press the soil down quickly and firmly. This should be an adjunct to every well-regulated hotbed. So should a thermometer, hung on the back wall of the hotbed, the bulb level with the soil. After the seeds are all sown, if the soil is at all dry, sprinkle carefully with a rubber sprinkler, or a whisk-broom dipped in water and shaken over the bed. Do not use the watering-pot, as it will wash the seed out of the ground. When the plants are up and of some size the watering-pot may be resorted to, but not before. When all the seeds are sown as directed cover with newspapers and close the sash.
