During the bright warm days the sash of the hotbed should be raised or entirely removed, but be very watchful of the weather. Spring is such a treacherous time of year that the warm mornings may develop into frosty afternoons. Always replace the sash over the hotbed by three o’clock in the afternoon, and cover with mats before dusk. As soon as the ground is in condition for the outside nursery beds, dig and thoroughly cultivate, for the plants which are to be held over for fall sales must be bedded out as soon as all fear of frost is past, and seeds sown for the next year’s stock. The seed-beds in the open ground must be well prepared and made very fine and fibrous. Sow the seeds in rows and transplant as with the house seedlings. Beds must all be kept free from weeds and under good cultivation during the growing season. When severe weather comes in the fall, cover lightly with leaves or soil, and the plants will winter safely and be ready for spring sales the following year. The house-raised seedlings which are to be sold for this year’s bedding can go into garden beds, but it is really better to put them into small individual pots, which should be partly submerged in soil or sand. Customers will usually pay a few cents extra for pot-plants. There is such an endless variety of perennial plants that it is impossible to grow them all; in fact, it would be very foolish to try to do so. Select the best-known and most popular kinds, and have some of different sizes, so that you can make up selections for beds. Hollyhocks, foxgloves, golden glow, monk’s-hood all range from three and a half to five feet in height. After them come phlox, larkspur, false dragon’s-head, Canterbury bells and bergamot. A step lower are bleeding-heart, columbine, leopard’s-bane, asters, sweet-williams and wallflowers. Still lower are Iceland poppies, Japanese primroses, wake-robin and pansies. The first year it would add to your profit to grow a few of the annual varieties in the hotbed collection: Hollyhocks, sweet sultans, sweet tobacco, asters, wallflowers, mignonette and salvia. Among the perennials which will flower the first season if seed is sown in boxes or hotbeds, are monk’s-hood (which is one of the most charming of the tall blue flowers and comes also in white, and blue-white mixed); larkspur; Chinese bellflower (large bell-shaped flowers of steel blue, white and violet); heliotrope and marshmallows (pink, rose colour, white with crimson spots, and golden yellow with maroon centres)--these are amongst the most valuable of the first-year bloomers, for they flower all through the summer. Three of the most fragrant annuals are sweet tobacco, sweet sultan and mignonette.
