How to Grow and Care for Carolina Jessamine: Methods and Precautions
When people mention French perfume, many are unfamiliar with this plant. It is a flowering plant native to the southern United States and Central America. It gets its name because its light, abundant small flowers give off an intoxicating jasmine fragrance, much like the scent of French perfume. This unique characteristic has won it the affection of many flower enthusiasts, who plant it one after another.
How to Grow Carolina Jessamine
Soil: One week before planting, prepare the flowerpot and soil. For the pot, choose a neutral pot, with ceramic or clay pots being suitable materials. For the soil mix, combine garden soil, leaf mold and residue in a 6:2:2 ratio, keep it loose, add a small amount of clean water, and leave it in a cool place for one week.
Watering: Bury the roots of the Carolina Jessamine in soil, press firm, and water with clean water at the right time to settle the roots. Do not use too much water. Afterwards, water by the "dry-wet" method, avoiding leaving the plant waterlogged or too dry.
Fertilizing: For routine fertilizing of Carolina Jessamine, choose mainly organic fertilizer, or diluted chemical fertilizer such as nitrogen, phosphorus or potassium fertilizer. Fertilize once every 2 months, burying each application in shallow soil at least about 6 cm away from the roots.
Temperature: Carolina Jessamine dislikes low and high temperatures, so it is only suitable for growing in southern regions and similar areas. The optimal temperature is 18-28 degrees Celsius, the minimum temperature is 10 degrees Celsius, and the maximum temperature is 30 degrees Celsius. Temperatures that are too low or too high will cause the plant to wither on its own and will also affect the flowering period.
Carolina Jessamine Growing Methods and Precautions
1. Growing Soil
Carolina Jessamine is suitable for planting in peat soil or leaf mold that has good air permeability and is loose and fertile.
2. Growing Temperature
The suitable growing temperature range for Carolina Jessamine is around 18-28°C. At night the temperature is relatively lower and can be kept at 10-20°C. When the temperature is too high or too low compared with these two ranges, growth will be restricted. In particular, when the temperature stays too low for a long time, it will enter a dormant state, and young seedlings are relatively less cold-tolerant. The suitable temperature for the development of flower buds is 15-20°C, and the night temperature should not be lower than 10°C, otherwise the flower buds will gradually wither and drop.
3. Growing Light
Carolina Jessamine is a sun-loving, light-loving plant, so it is not suitable for long-term growth in shady places. However, in summer it must not be exposed to overly high temperatures and strong sun; use a 50%-70% shade net for cover, but excessive shading will also delay its flowering period.
4. Water Requirements
Carolina Jessamine should be kept in a "dry-wet" state in the pot, and must not be overly waterlogged, otherwise it will cause root rot and other root damage. 5. Fertilizer Management
During the seedling stage, apply a compound fertilizer with nitrogen, phosphorus and potassium, keeping the EC value of the medium within the range of 0.8-1.0; during the medium and large seedling stages, apply a nitrogen-phosphorus-potassium compound fertilizer and keep the medium EC value between 1.5-1.8; during the flowering period, apply nitrogen, phosphorus and potassium and keep the medium EC value within the range of 1.2-1.5.
II. Precautions
1. When growing Carolina Jessamine, attention should be paid to its differentiation treatment, and it should be pruned appropriately to avoid leggy growth, which would directly lead to a lack of nutrients and to inaccurate or delayed flowering.
2. Before the flowering period, Carolina Jessamine can be appropriately sprayed with diluted boron or amino acid substances, which can supplement nutrients as needed and nourish the flower color; the plant's flower shape will also be healthier, with green leaves and bright flowers.
3. For potted Carolina Jessamine, the most commonly encountered diseases and pests are gray mold and powdery mildew. Calcium, boron and the like can be sprayed, and pests can also be removed by hand.
Is Carolina Jessamine Toxic
The whole plant contains alkaloids and is toxic (the flowers and young leaves are the most toxic). The plant sap causes strong allergic reactions in some people's skin, so protection should be taken when pruning, and it must never be eaten. Accidental ingestion of Gelsemium elegans may cause the intestines to stick together and continuous abdominal pain.
Once a similar situation is discovered, seek medical treatment promptly. If time is pressing, you can first give the person who swallowed it some mung bean soup, or goose blood, duck blood or sheep blood; this has been proven clinically to have some effect. So far there is no specific remedy, only conventional methods such as gastric lavage, purging, diuresis and activated charcoal adsorption of toxins. If a large amount has been swallowed, after drinking mung bean soup you must go to the hospital for treatment, otherwise once it is absorbed by the tissues it may well be fatal.
When Does Carolina Jessamine Bloom
Carolina Jessamine generally blooms in autumn. Its natural flowering period is from October to April of the following year, lasting a very long time. A single flower also stays open for a long time, lasting 15 days or even 25 days.
In autumn, Carolina Jessamine produces yellow trumpet-shaped flowers. The flowers mainly open at the tips and have a relatively rich fragrance. In temperate regions, Carolina Jessamine can also bloom in spring.
Carolina Jessamine likes a growing environment with plenty of light, warmth and humidity, and its growing method is not very difficult. Generally it can grow very lushly under fertile, moist conditions. However, it is mildly toxic, so during cultivation take care to avoid its sap to prevent harm to the human body.
