How to regulate the flowering period of Calendula so it grows lush and blooms in all four seasons
Calendula (pot marigold) is a very common potted flower in the home. Getting it to bloom in a pot is by no means the ultimate goal of flower lovers; lush, vigorous growth is what brings more joy. How do you make calendula grow lush and bloom in all four seasons?

[Start with seed selection]
Of course, growing calendula should start from seed, since that is what gives a sense of achievement. Calendula matures right at the turn of spring and summer, when there is more rain, and the harvested seeds vary in quality, so choose high-quality ones when selecting seeds. Before planting, you can soak the seeds first and discard the ones that float on the surface of the water.
[Cover with a slightly thicker layer of soil]
When sowing, to let calendula grow strong, you can cover it with a thick layer of soil. Calendula has a very high germination rate. When the seedlings grow to 3 leaves, they can be transplanted; transplanting at the right time is what promotes root development.
[Control water and fertilizer]
During the growing period, calendula should not be watered too much; keeping the soil moist is enough. High humidity, heavy rain or high-temperature weather easily cause root rot, leading to plant death. Pay attention to fertilizing during the growing period: apply a thin liquid fertilizer once every 20 days. Before and after flowering, applying 2~3 times a quick-acting fertilizer based mainly on phosphorus and potassium helps the growth of calendula.
[Pinch off the growing tips in time]
After the seedlings are transplanted, pinch off the growing tips when they reach 6 leaves to encourage side buds to sprout and produce more flowers. If you like calendula to bear large flowers, you can skip pinching, but as the plant grows you must keep removing the side buds, which concentrates nutrients and promotes flower bud development. In this way, calendula can both grow lush and produce very large blooms.
Calendula plants are dense, and their flower colors are dazzling and eye-catching. Orange-yellow, purple-red, yellow and other colored flowers, shining in the sunlight, look noble and elegant. Calendula's flowering period is in early spring. If you want the beautiful calendula to bloom in all four seasons, you can regulate its flowering period, so that you can enjoy beautiful calendula flowers in all four seasons.
[Methods for regulating the flowering period of calendula]
Calendula's usual flowering period is early spring. If you want it to have flowers in other seasons, you need to take separate technical measures; in this way you can make calendula bloom in all four seasons.
1) Calendula blooming in autumn. After flowering in early spring, promptly cut off the spent flowers, and at the same time strengthen fertilizer and water management to encourage new branches to sprout. In the hot summer, it should be moved to a ventilated, cool place, and attention paid to watering; in this way it will bloom again in autumn.
2) Calendula blooming in summer. It needs to be sown at the end of March. For courtyard landscaping, it can be broadcast directly. After the seedlings come up evenly, thin out the overly dense ones appropriately, then pay attention to reasonable fertilizer and water management; it can bloom in June.
3) Calendula blooming in winter. Sow in late August, transplant into pots after the seedlings emerge, and move into a greenhouse at 8~10°C after the frost falls to grow them, keeping the soil surface moist and fertilizing; in this way it will bloom in the depths of winter.
Calendula is magnificent and splendid. Planting a pot of calendula makes the whole room bright and comfortable. By regulating the flowering period of calendula, you can make it bloom in all four seasons, so why not do it?
