Sow seeds in a mild hotbed in early spring; transplant the seedlings when about two inches tall to small pots or flats, and again to the garden when the ground becomes warm. Later and successional sowings may be made in the open ground. For winter blooming seeds may be sown in midsummer, when cuttings may also be taken. Any garden soil suits them.
Sow seeds in a mild hotbed or greenhouse in early spring and transplant the seedlings to small pots when about two inches tall. When the weather becomes settled transplant in the open ground in ordinary soil. Allow five feet between plants. Division of the clumps is the usual method of propagation after the plants have become established.
See Balm, Fragrant.
Sow in the garden as soon as the soil becomes warm, and when about two inches tall transplant about a foot apart in any partially shaded soil. Cuttings readily strike root, and the clumps may be divided.
Plant the bulbs in the spring in any garden soil, rather light preferred, sinking the corms three or four inches deep and eight inches apart. Plant suc-cessionally every ten days or two weeks. In autumn dig, clean, divide and store the corms in moist earth. Don't have them wet. Farther south they may be left where they grow with a mulch of leaves or Utter as protection. In such cases they should be dug every three years.
File the points of the seeds or cut small notches in them, to hasten and insure germination. Sow in late winter in a moderately warm greenhouse or hotbed. When two or three leaves have appeared transplant the seedlings to small pots, and when danger of frost has passed set in deep, rich soil and provide a straight wire or string trellis twenty to thirty feet tall. Cuttings may be taken in early autumn for winter flowering. The plants are twining.
Sow seeds as soon as the ground can be worked where the plants are to remain, choosing a warm, sunny place and ordinary soil. Provide straight wire trellis or strings (the plants twine) six or eight inches apart. In ordinary soil the plants should reach ten feet; in rich, much more. In the latter they will usually be less floriferous and later in blooming, but will produce greater shade. They self-sow readily.
Plant divided plants in any soil among rocks and in borders where a mat of low herbage is desired. The plants will care for themselves with only an autumn dressing of litter or manure.
See Kbnilworth Ivy.
Sow seeds in the open ground or in a mild hotbed. Transplant while small to ordinary garden soil, the dwarf varieties about six inches apart and the tall ones as much as two feet. The perennial species may be divided, but some of them act like biennials and should be sown annually. For indoor blooming the seed may be sown in late summer.
See Hyacinth, Grape.
Cultivate like Monkey-flower, which see.
Cultivate like Daffodil, which see.
Sow the seed singly in two-inch pots in the hotbed or greenhouse in early spring and transplant to poor soil, the dwarf varieties about a foot apart, the tall ones two to four. The seeds may also be sown in the open ground when the soil becomes warm. Choice varieties or colours may be easily propagated by cuttings - the usual way for obtaining plants for winter blooming.
Sow the seed in a cold-frame in early spring and transplant while the plants are very small six inches apart in good soil. For earliest bloom the seeds may be sown in early autumn where the plants are to remain, and protected during the winter with a light mulch of leaves or straw. Some of these late-sown plants may be potted and removed to the cool greenhouse for winter blossoming.
Sow seeds in mild hot-bed or greenhouse in early spring or late winter; transplant when about two inches tall to small pots, and when danger of frost has passed set in good garden soil, about two feet apart. From Washington southward the plant often self-sows, and in the South it lives over winter. For winter blooming sow seeds in late summer and give ordinary attention.
Since seedlings must usually be two years old before they will flower, division of established clumps in the spring is preferred. The plants thrive best in rich, light, rather moist loam. Since the plants are rather tender in the North, thev should be protected during the winter with a mulch of straw or leaves several inches thick and held in place by boards or boughs.
For early spring flowering sow in the autumn, and when the plants have three or four leaves transplant about three inches apart in coldframes, which must be protected from inclement weather during winter. In early spring the plants may be set about five inches apart in light, rich soil. They do best in partial shade, especially if flowers are desired during the summer, a season which reduces the size of the blossoms. Spring-sown seed rarely produces as satisfactory plants as autumn-sown.
Sow seeds where the plants are to remain, but avoid placing them in borders with shrubbery, etc. Among rocks, in waste places, and in any kind of soil they will thrive.
For earliest bloom sow the seeds about four inches deep in late autumn where the plants are to remain, choosing a deep, rich, rather heavy loam and a dry situation. Spring successional sowings should commence with the opening of the season, the seeds being sown in trenches from four to six inches deep, but being covered with less than two inches of soil. Thin the seedlings to stand eight inches apart, and, as they grow, draw soil toward them* until they are ridged an inch or more above the level. Provide trellis of poultry wire, brush or strings. For long season of bloom cut the flowers daily. Dwarf sweet peas need no trellis and may stand as close as twelve inches.
