Propagation of calendula
Greenhouse: If you lift the smaller, flowering plants from the mid-summer sowing before frost, you can enjoy a few flowers during the winter. Plant them individually, in 6- or 7-inch pots filled with rich soil. Keep the greenhouse well ventilated and light and you can maintain a succession of flowers. The greenhouse should be between 40 and 55 degrees at night. For the best results, sow seeds from mid-July to mid-August to have flowers from October to February. Plant them in a flat or pot inside, or in a sheltered area outside where shade is available until they sprout. Well-drained garden loam that is constantly moist is good for germination. The seedlings should be transplanted to separate 3-inch pots as soon as they're large enough to safely handle. The soil to use for this potting should be loam (good topsoil) of a friable nature. Grow the plants in partial shade until their roots almost completely penetrate the soil. They should then be planted in the place where they are to flower (before they become too cramped) in well-drained garden loam that is enriched with thoroughly decayed organic matter and a bit of 5-10-5 or other fertilizer high in phosphorous. This final potting can be in pots, 6-8 inches in diameter, although they will grow better in benches of soil; either way, they need an airy greenhouse where the temperature drops to 45 or 50 degrees at night in the winter. Plant them 12-15 inches apart in soil that is 5-6 inches deep. If a second sowing of Calendulas is made late in October in the greenhouse, you will have flowers from February to April. Good ventilation of the greenhouse is essential, especially if the plants are a bit crowded. When there isn't adequate ventilation, a leaf spot disease may destroy the crop. Thin them to 7 or 8 branches on each plant and some unnecessary side growths in order to produce large flowers with long stems.
