A Detailed Guide to Growing Calendula and Its Medicinal Benefits
Calendula is one of the chrysanthemum varieties, with a very nice appearance and brilliant flower colors. It is an excellent potted flower, and its flowers can also be brewed as tea. It can be said to combine ornamental value and medicinal value in one. Below are the medicinal benefits and growing methods of calendula, for your reference.
1. Sowing
First, place drainage stones at the bottom of the flower pot to help the soil "breathe," then pour two-thirds of the soil into the pot, scatter the seeds, and cover with a layer of soil. Keep the soil moist during the sowing period.
2. Temperature
The germination temperature for calendula seeds is 18-20°C; germination takes 6-10 days; the suitable growing temperature is 10-30°C. It likes a warm climate and dislikes extreme heat. When the summer temperature is above 34°C, its growth is noticeably poor; it is not tolerant of frost and cold, and when the winter temperature falls below 4°C, it enters dormancy or dies. The optimal growing temperature is 15-25°C. The soil should be kept moist during the growing period of calendula.
3. Light
In spring, summer and autumn, it needs to be cared for under shaded conditions. When the temperature is relatively high (daytime temperature above 25°C), if it is placed in direct sunlight, the leaves will noticeably become smaller, the internodes of the branches will shorten, the lower leaves will turn yellow and drop, and growth will be very slow or it will enter a semi-dormant state.
In winter, since the temperature is not very high, it should be given direct sunlight to help it carry out photosynthesis and form flower buds, bloom and set seed.
After keeping it indoors for a period during the flowering season (10-15 days), it should be moved outdoors to a place with shade (and warmth) for a period (about one month), and alternated back and forth in this way to help the plant accumulate nutrients and continue blooming.
4. Watering
Many people think that more watering is needed in summer, but this is actually wrong. Because the temperature is too high and calendula fears heat, the frequency should be appropriately reduced. Generally, for plants outdoors, water once every 9-15 days, while for indoor plants, water once every 12-21 days. When watering, choose nighttime or early morning when the temperature is lower, and keep the leaves dry at night. In winter, the watering interval needs to be longer, and the time should be chosen at noon on a sunny day when the temperature is relatively high. Generally, whether indoors or outdoors, water no more than 2 times per month, always keeping the plant dry.
5. Pinching and Pruning
Before flowering, generally pinch twice to encourage more flowering branches to sprout. Pruning: cut off branches with old and yellow leaves once every two months. As long as the temperature is suitable, it can bloom in all four seasons.
6. Fertilizing
Calendula has a relatively high demand for fertilizer and water, but the fertilizing (and watering) principle of "light fertilizer applied frequently, small amounts and many times, complete nutrition" should be followed, and after fertilizing, the leaves and flowers should be kept dry at night.

The tansy flower is button-shaped and yellow; the leaves are somewhat lemon-shaped and bitter, and fresh leaves are used in salads. Fresh or dried leaves are used as a seasoning, especially as a flavoring for meat and poultry and for English pale ale; dried leaves can be used as tea or in potpourri jars.
All parts of tansy are poisonous.
Morphological Characteristics of Tansy
Tansy is a perennial herb, 30-150 cm tall. The stem is erect, single or a few stems clustered together, branched only in the upper part, with extremely sparse simple hairs, but usually smooth and hairless. Stem leaves numerous, the overall shape elliptical or elliptically ovate, up to 25 cm long, two-pinnately divided. The first division is fully divided, with up to 12 pairs of lateral lobes; the second division is deeply divided, the second-order lobes ovate, linear-lanceolate, obliquely triangular or long elliptical, with margins entire or with shallow teeth, or partly divided so that the leaf becomes three-pinnately divided.
The rachis has jointed teeth. Lower stem leaves have long petioles, middle and upper stem leaves are sessile. All leaves are green or pale green, with extremely sparse hairs or nearly hairless. Capitula numerous (10-20) arranged at the top of the stem and branches in dense corymbs or compound corymbs. Involucre diameter 5-13 mm. Involucral bracts in 3 layers, herbaceous. Outer layer ovate-lanceolate, about 1.5 mm long; middle and inner layers lanceolate or long elliptical, 3-4 mm long. All bract margins white or light brown narrowly membranous, apex membranously enlarged. All florets tubular, marginal female flowers smaller than bisexual flowers.
Tansy achenes 1.2-2 mm long. Pappus corona 0.1-0.4 mm long, corona margin shallowly toothed.
Tansy flowering and fruiting period June-August.
Ecological Habits of Tansy
Tansy grows on mountain slopes, riverbanks, grasslands, hilly land and under birch forests, at an altitude of 250-2400 m.
Tansy has strong adaptability, is drought-tolerant and barren-tolerant, and is not strict about soil requirements. Its cold tolerance is relatively poor; in cold northern regions, soil should be mounded over the roots in winter to help it overwinter. Seeds are difficult to germinate and the germination rate is low. Before sowing, soak the seeds in 30°C warm water for 8-12 hours and rub off the surface mucilage. The seedbed must be carefully finely prepared and leveled; after sowing, cover with a small amount of fine soil and cover with plastic film to keep warm and moist. When the seedlings grow to 6-8 true leaves, they can be transplanted, either in pots or in the ground.
After the seedlings recover, pinch when the main stem is 15 cm tall to encourage side branches; when the plant is 30 cm tall, it can be harvested.
Tansy Cultivation Techniques and Key Growing Points
Sufficient sunlight, good ventilation, and well-drained sandy loam are best and favorable for growth.
When tansy plants are 30 cm tall, fertilizer can be applied to allow the leaves and stems to grow fully. Because of its special leaf shape and the special need for silver color, in recent years it has often been used by floral art teachers as a floral material.

Tansy Propagation Methods
Tansy is commonly propagated by sowing. Seeds are sown directly, 3-5 per hole. When the plant is 5 cm tall, thinning must be done to favor growth.
Tansy Disease and Pest Control
1. Leaf spot, also called leaf blight, brown spot, powdery mildew, etc. When the lower leaves are affected, round or elliptical yellow or purplish-brown lesions of varying sizes appear, later turning dark brown, with the center of the lesion sunken. In severe cases, the entire leaf turns black and dries up, hanging on the stem. Control methods: clear away dead leaves and diseased leaves in early winter; choose strongly disease-resistant varieties; during the period from chrysanthemum seedlings to finished products, spray 3 times with JUBIZHI or carbendazim, zineb, chlorothalonil, etc., alternating the sprays.
2. Viral disease: leaves mostly wrinkled and deformed, showing mosaic, plants stunted, poor growth or deformed flowering, etc. Control methods: control the spread of pests and diseases, such as red spider mites, whiteflies, leafhoppers, etc.; promptly remove diseased plants; propagate with robust basal shoots and stems; carry out virus elimination or heat treatment, and tissue-culture virus elimination is also possible.
3. Long-tubed aphid: a very small and soft piercing-sucking pest, brown and glossy, harming tender shoots, young buds and flowers, affecting plant growth and flowering.
Control methods: regularly clear field weeds and dead branches and fallen leaves to reduce overwintering aphids; protect natural enemies such as seven-spot ladybirds, hoverflies, green lacewings, etc.; spray BIK or JINJIER once every 15 days.
4. Green plant bug: mainly harms tender leaves. Adults are 5.0 mm to 5.5 mm long, yellow to light green. Control methods: light trapping; during the nymph hatching period, spray dichlorvos at 1500 times dilution, spraying once every 10 days.
5. White grub: the larva of the scarab beetle, living in the soil and gnawing on seedlings. The body is white, plump and soft, with the head orange-yellow or brown, and the end of the abdomen curved toward the belly in a "C" shape.
Control methods: deep plow the land in winter, place poisoned bait (fresh grass or beans mixed with zinc phoxim 1000:1) to trap and kill, or dig and catch by hand in the early morning; about 250 grams of zinc phoxim stock solution can also be appropriately diluted and evenly irrigated into the water. During the peak period when adults emerge from the soil, spray the ground with zinc phoxim at 1000 times dilution, or dip fresh leafy branches in omethoate 600 times dilution and insert them into the soil of the flower garden in the evening to trap and kill adults.

Tansy Uses and Purposes: Spice Use
Tansy is a world-famous spice plant. Its plant form is elegant and its flower colors are charming. The whole plant has a strong fragrance. It has ornamental value, can beautify and fragrance the environment, and can also repel mosquitoes and flies.
Use Value
The stem and capitula contain insecticidal substances and can be used as an insecticide. The special fragrance of tansy can repel mosquitoes and insects. The whole herb contains tanacetin, tanacetol A, tanacetol B (tanacetol A, B). The components in the volatile oil include thujone; the leaves contain viburnol; the flowers contain cis-longipinane-2,7-dione.
Its special fragrance and strings of small flowers made it a symbol of "faithful until death" for lovers in ancient times! The strong aroma has an invigorating effect, and it is said to enhance memory and treat headaches and migraines. Although it originates along the Mediterranean coast, it can adapt to extremely harsh weather environments. However, its favorite climate is still a warm, ventilated environment with sufficient sunlight, as well as well-drained alkaline sandy loam. In summer, avoid torrential rain and strong direct sunlight. It can be propagated by seeds and cuttings, but the seed germination rate is relatively low, so cuttings are usually used for propagation in autumn. In addition to blue flowers, there are also pink and white varieties.

Tansy Cultural Background and Historical Story
Tansy originated in Europe. When it blooms, it turns the area golden, like steaming rosy clouds. In addition to being spectacular and full of vitality, tansy also has extremely high medicinal value and is quite popular, so it was gradually transplanted to the United States, South America, Australia and other places.
But before long, the people who transplanted tansy were shocked to find that it posed a great threat to the local ecological environment: because tansy has extremely strong reproductive capacity, it quickly swallowed up large amounts of fertile land. If the situation got out of control, other local plants might lose their chance to survive; in addition, tansy contains pyrrolizidine alkaloids, which poisoned many innocent local livestock. In this way, the original "pretty lady" became today's ecological "invader."
However, it was already impossible to drive it all back to its "old home," yet leaving it there left people at a loss. Helpless, people sought a win-win solution from experts. Although the experts' suggestion was incredible, people still followed it, not daring to be the slightest bit careless. Soon, people were joyfully surprised to find that the domineering and powerful tansy had once again become pretty and lovely. It could grow tamely in the local area, satisfying people's aesthetic and medicinal needs, and could also coexist peacefully with other organisms. The plants previously harmed by tansy also resumed growing.
It turned out that the experts' good solution was: since you love tansy, then love its natural enemies together with it. Under the guidance of experts, people introduced tansy's natural enemies, the cinnabar moth and leaf beetles. Both natural enemies feed on tansy leaves, and they and the tansy leaves are "quarrelsome lovers" that restrain and depend on each other.
After the turmoil brought by tansy, people began to understand: to transplant a foreign plant or foreign organism into a place, one must consider accepting its natural enemies along with it. This is truly a profound ecological rule that gives birth to miracles.
In fact, the principle contained in this story also applies to us humans and life. For example, to love a person, you need to love their shortcomings together; for example, to enjoy the sweet happiness of life, you need to endure life's pain and unhappiness together; for example, a harmonious society needs various interests and forces to restrain, balance and supervise each other.
Tool
In the Middle Ages, it was an important tool of witchcraft, along with other items - mistletoe (a Christmas decoration, the one hung on doors with small red fruits).
Tansy's Birthday Flower
August 23 birthday flower: Tansy (tansy)
Flower Language: Charm
Tansy is distributed very widely. In terms of latitude, from the Mediterranean to the Arctic Circle; in terms of longitude, from Europe to Siberia. Its traces are found almost all over the world, making it a plant with strong adaptability. Therefore, its flower language is Charm.
People born under the blessing of this flower have very good popularity. Even when with strangers, they can quickly become one with everyone. They are easygoing and friendly by nature, but are relatively unable to develop deeper feelings with specific friends, so love may be full of difficulties!
In ancient Christianity, there was a custom of linking saints with specific flowers, because when the church commemorated saints, it usually decorated the altar with blooming flowers. After the Middle Ages, in Catholic monasteries, various flowers were planted almost like gardening centers. Over time, the church combined the 366 days' saints with different flowers respectively, forming the so-called flower calendar. Since most monasteries at that time were located in Southern Europe, and Southern Europe has a Mediterranean climate, it was very suitable for planting flowers and plants. All kinds of flowers bloomed competitively, and each flower had rich meanings.
