Soil

Calendula does not have strict soil requirements and prefers to grow in fertile, well-drained alkaline sandy soil. The soil pH is best around 6-7. Sufficiently fertile soil ensures that calendula will branch more and bloom more.

Light

Calendula prefers to grow in an environment with ample sunlight, but high-temperature environments should be strictly avoided. Under high-temperature conditions in summer, it needs to be placed in a shaded area for care. If the temperature is too high, it can easily cause calendula to grow slowly and enter a semi-dormant state.

Temperature

The suitable temperature for calendula growth is 15 to 25 degrees. It is not tolerant of cold or frost. When summer temperatures are too high, it will also show obvious poor growth. When the temperature is too low, it will also enter a dormant or dead state.

Fertilizing

After calendula is planted, 7-10 days later, pinching should be carried out, which can encourage calendula to branch more. Spray the leaves of calendula with a 0.4% daminozide solution 1-2 times to regulate the plant height of calendula. During the growing period, fertilize calendula once every half month. Sufficient fertilizer can make calendula bloom more and larger.

Calendula Growing Methods

1. Soil: It is not particular about soil. Fertile, loose, and well-drained sandy loam or potting mix is suitable, and the best soil pH is 6-7. In this way, the plant will have more branches and produce large and numerous flowers.
2. Sunlight: In spring, summer, and autumn, it needs to be cared for under shaded conditions. When the temperature is relatively high (daytime temperature above 25 degrees C), if it is placed in direct sunlight for care, the leaves will noticeably become smaller, the internodes of the branches will shorten, the lower leaves will turn yellow and fall off, and growth will be very slow or it will enter a semi-dormant state. In winter, it should be given direct sunlight to facilitate photosynthesis and the formation of flower buds, flowering, and seed setting.

Calendula Growing Methods

Calendula, also known as pot marigold and golden cup. An annual or biennial herb in the Asteraceae family.

   Morphological characteristics: Plant height 20〜30, the whole plant covered with fine hairs. Leaves alternate, oblong to obovate-oblong, entire or with inconspicuous serrations. Capitulum, solitary, flower diameter 4〜8 0!1, ligulate flowers yellow or orange, tubular flowers yellow or purple. Achene curved. There are many cultivated varieties.

   Growth habits: Native to the Mediterranean coast from the Canary Islands in southern Europe to Iran. It is relatively cold-tolerant and can overwinter outdoors in the Yangtze River basin. It likes sun and is slightly shade-tolerant. It has strong adaptability and does not have strict soil requirements, but grows better in loose, fertile soil. It easily self-sows and reproduces.

   Propagation method: Mostly by sowing. It is usually cultivated as a biennial. In East China, autumn sowing is in early to mid-September. After sowing by conventional methods, seedlings emerge in 7〜10 days. When the seedlings grow 4〜5 true leaves, they should be transplanted and temporarily planted. They can overwinter outdoors in a wind-sheltered, sunny place. Calendula grows quickly and has large leaves. If overwintering in a nursery, it should be transplanted and planted in time in early spring. When cultivated as an annual, it is often sown in early July and can bloom in autumn. The seed viability of calendula is 3〜4 years.

   Cultivation and care: Calendula has strong adaptability and grows quickly and robustly. After autumn-sown seedlings are transplanted or thinned and grow 5〜6 true leaves, they can be planted in the ground or potted. In East China, potted seedlings are mostly cultivated under protected conditions or on south-facing enclosed balconies. After planting and before overwintering, apply 1〜2 topdressings. After growth begins in early spring, apply a compound fertilizer once every 7〜10 days. Flowering begins in late March, full bloom is in early May. After flowering, spent flowers should be removed in time to keep blooming continuously. Usually by June〜July after summer arrives, poor growth occurs due to high temperatures. Summer-sown seedlings, after timely transplanting and planting, bloom in September〜October. Their care requirements are the same as the methods after planting autumn-sown seedlings, with the only difference being that cold protection is not needed, while attention should be paid to fertilizer and water management when overwintering through summer.

   Pest and disease control: Powdery mildew is the main disease of calendula. The affected parts are mostly leaves and stems. In the early stage of the disease, white powdery mildew-like round spots appear, and finally develop until the leaf surface, leaf back, and stems are all covered with a white powdery layer, causing the plant to stop growing and leading to yellowing and death. This disease is likely to occur under dry conditions at 20〜241 and spreads extremely quickly. Excessive plant growth also makes this disease more likely to occur. Control methods_：0 Remove diseased leaves and diseased plants, and destroy them. ② In the early stage of the disease, spray 15% triadimefon wettable powder at 1,000〜1,200 times dilution or 20% thiophanate-methyl wettable powder at 1,000 times dilution for control.
