What are the care methods to make potted wintersweet (winter sweet, Chimonanthus praecox) bloom more?

Wintersweet likes sunlight and tolerates partial shade slightly; it is drought-tolerant and afraid of waterlogging, so it is best planted in sandy loam rich in humus. To make it bloom more, potted plants should use a large, deep cylindrical flowerpot, with loose, fertile, well-drained sandy loam as the growing medium. When potting, apply decomposed base fertilizer at the bottom of the pot. It is best to repot once a year or every other year, and repotting should be done before budding in spring. At ordinary times, keep it in a sunny place.

Wintersweet likes fertilizer. In spring, apply leaf-expanding fertilizer twice; from the end of June to before the dog days, apply a compound liquid fertilizer once every 10~15 days. The dog days are exactly the flower bud differentiation period and also the vigorous new root growth period, so 1~2 more applications of phosphorus and potassium fertilizer can be made to promote flower bud differentiation. However, fertilization during the dog days should be thin, otherwise it easily causes root rot. After the autumn turns cool, apply dry fertilizer once (about 50 grams of cake fertilizer powder per pot) to plump up the flower buds. Before winter begins, apply a thin compound liquid fertilizer once more to supply the nutrients needed for flowering. When fertilizing wintersweet, phosphorus and potassium fertilizer should be the main ones, with an appropriate amount of nitrogen fertilizer; the approximate ratio of the three is 2:1:0.5, which can make wintersweet flowers large, numerous and strongly fragrant.

Wintersweet is drought-tolerant, hence the saying "wintersweet will not die of drought." But it dislikes waterlogging; if watered too much and the potting soil is too wet, the plant grows poorly, and with too much water during the flowering period it also tends to drop flowers; if the potting soil is too dry, it is also unfavorable for its growth, and the flowers are both sparse and irregular, so it is best to keep the potting soil in a semi-moist state. In summer, when the weather is hot, water must not be lacking; during the peak growth season, watering should also be somewhat more, and during the growth stagnation period, the amount of watering should be controlled and fertilization stopped. Wintersweet has strong sprouting ability, so after the flowers fade it can be heavily pruned to encourage more branches and more flowers. When the flowers fade, the remaining flowers should be removed as early as possible so they do not set seed, reducing nutrient consumption and helping abundant flowering the following year. In the north, at the end of October or the beginning of November, move the flowerpot indoors to a low-temperature, sunny place for care, and it will bloom at the proper time.

Potted wintersweet does not bloom | Potted wintersweet grows luxuriantly but does not bloom

① Seedling-grown plants are cultivated. Wintersweet seedlings sown from seed must grow for 3~5 years before entering the flowering and fruiting stage. Therefore, although potted seed-grown seedlings have sufficient water and fertilizer and flourish with branches and leaves, they will not bloom early.

② Too much nitrogen fertilizer. Some wintersweet plants, due to uncontrolled water and fertilizer, especially excessive nitrogen fertilizer, grow rampant branches and leaves, affecting flower bud differentiation and causing failure to bloom. Therefore, wintersweet should be given nitrogen fertilizer in spring, and in summer and autumn more phosphorus and potassium fertilizer should be applied and less or no nitrogen fertilizer, to promote flower bud differentiation as early as possible.

③ Excessive shade and dampness. Wintersweet likes light, and insufficient light will affect flower bud differentiation; potting soil that is too wet or a location that is too shady and damp is also unfavorable for flower bud differentiation. For this reason, in late summer and early autumn, water should be "withheld," and it should always be placed in a place with ample sunlight, which can greatly help the formation and swelling of flower buds.

④ No pinching or topping. For wintersweet that has already entered the flowering stage, if during the spring and summer vegetative growth period it is allowed to sprout branches freely without the necessary topping and shoot control, then likewise the uncontrolled vegetative growth will affect flower bud differentiation and growth. Generally, when 3~5 pairs of leaves have emerged at the shoot tip, the top 1/3 should be removed in time to promote the sprouting of lower side buds and normal flower bud differentiation. In late summer and early autumn, topping and pinching must especially not be neglected.
