What is Camellia? Perhaps many people don't know much about it. The color of camellia is red with a little pink, like a slim, beautiful girl. A gust of wind blew, blowing its faint scent into the nose. How is camellia cultured? Let's take a look. Growth habit Camellia is fearful of wind and sun, high ground, air circulation, warm and humid, well-drained, loose and fertile sandy loam, loess or humus. The best pH is 5.5-6.5. The temperature is between 20-32 ° C. When the temperature is above 29 ° C, the growth stops. At 35 ° C, the leaves will have a burning phenomenon, which requires a certain temperature difference. The ambient humidity is above 70%, most of the varieties can withstand -8 °C low temperature (natural wintering, cloud tea is not cold-resistant), in the south of the Huaihe River, it is generally natural to over-winter acid soil, and requires better gas permeability. The root hair development is usually cultivated with peat, rot sawn, red clay, humus, or a mixed substrate of the above. Camellia spring and autumn and winter can not be shaded, 50% shading in summer. Camellia cultivation and maintenance method 1. Soil Soil is the basis for the growth of potted camellia. Because the roots of Camellia depend on soil growth and development, the water and nutrients needed for Camellia life activities are mainly absorbed from the soil. Camellia prefers the mountain red (yellow) loam with acidity, high humus content and loose ventilation. The pH value is between 5 and 6.5. The alkaline soil or the viscous soil cannot be used as the potted camellia substrate. Soil preparation: 50% of mountain soil (cured red loam of crops), 40% of wood chips or edible fungus residue, 10% of cake fat powder or livestock manure and phosphate fertilizer powder, mix well, watering and bagging, 20 days in summer and autumn Above, more than 30 days in spring and winter, this soil is not only loose ventilation, but also preserves fertilizer and water, suitable for the growth and development of Camellia. 2, lighting Camellia needs proper light, but it is afraid of high temperatures and direct sunlight. In the spring and late autumn, the camellia should be moved to the balcony or the ground where the light is visible, and the whole day is illuminated to promote the growth and development of the plant, and the flower buds are differentiated and the flower buds are strong. In the summer, the sun is the strongest. It is necessary to move the flowerpots to the light-backed, well-ventilated environment. It can also be moved to the north balcony or the south balcony to support. You can also use 75% shade net from 9 am. When the plant is covered by 5 pm, avoid direct sunlight, cause leaf wounds or small plants withered, and conditionally move the camellia to the sun shed for safer summer. 3, temperature Temperature is one of the important conditions for the growth of camellia. Camellia prefers warmth, and the optimum temperature for growth is 18°C ​​to 25°C, and the relative humidity is 60% to 65%. The growth of camellia, spring shoots generally sprout in the middle and late March, buds begin to bloom in April, and the top buds form in mid-to-late May, stop growing, and gradually differentiate into leaf buds or flower buds, from flower bud formation to flowering for 180 days to 240 days. The summer shoots sprouted in late July and stopped growing until early September. Although the mountain tea is resistant to low temperatures, when the cold wave invades, the temperature suddenly drops below 0 °C or encounters the dry northwest wind, it will cause frost damage to the shoots, and the flower buds will wither due to freezing damage. To this end, the pots are moved to the north to the south. Maintenance, making it safe for winter. 4, humidity There are many leaves of camellia, the leaf area is large, and the transpiration is fast. Camellia prefers a humid climate and also prefers moist soil. Therefore, the potted camellia should be replenished with water, watered once a day during the spring and autumn growing season, and watered once a day in the summer, especially in the “three daysâ€. If the ground is dry, water the ground and the surrounding area of ​​the pot or Spray water once or twice to maintain a certain amount of air humidity, and the plants will flourish. At the same time, note that due to the large amount of watering, and most households are pouring tap water, the soil of the pot will be alkalized for a long time. For this reason, when watering, 0.5% to 1% of ferrous sulfate water can be refilled every month, and 5% to 8% of edible acid vinegar can also be used to spray the leaves. Camellia likes moist soil, but it is afraid of water in the pot. If it is accumulated in the basin on rainy days, it must be removed in time to avoid suffocation and rot in the water.
Red Light Therapy is a skin care treatment being offered as an alternative to physician administered laser therapy. Most studies involving red light therapy revolve around the treatment of acne, rosacea, and of its ability to get rid of wrinkles. While research is not yet conclusive on the benefits of red light therapy, studies suggest that concentrated red light is absorbed by the mitochondria in the cells and stimulates the generation of more collagen
