What to Do About Flower Chlorosis? Vinegar Can Treat It and Promote Plant Growth

In flower cultivation, vinegar plays a role that should not be underestimated, with a remarkable ability to bring ailing flowers back to life. It contains beneficial substances such as sugars, glucose, lactic acid and acetic acid, and a vinegar solution can inhibit the biological activity of glycolate oxidase in the “photorespiration” process, raising the net photosynthetic rate by 10%—20%, strengthening photosynthesis, increasing chlorophyll content and enhancing the disease resistance of flowers. So spraying an appropriate amount of vinegar solution can make flowers grow vigorously, bloom abundantly and display vivid colors. Several uses are described below.

Treating chlorosis. Many flowers such as camellias, azaleas and foliage plants often develop yellow leaves due to a lack of iron, overly high pH of the potting soil, improper care and so on. In this case, use 10 grams of vinegar plus 3 kg of clean water and spray it on the plant leaves before 10 a.m. and after 4 p.m. Spray once every 10 days, and after 4—5 consecutive sprays the leaves can turn from yellow to green.

Promoting plant growth. Use a 300-fold vinegar solution and spray the whole plant before the camellia buds form, once every 15 days; this can increase camellia leaf size by 0.2—0.4 cm, increase the number of flowers by 8% and increase branching by 20%. Watering flowers and trees with a 150—2000-fold vinegar solution can overcome physiological diseases caused by alkaline potting soil pH.

Enhancing disease resistance. For example, rose powdery mildew, azalea black spot, and sooty mold on roses and peonies: once discovered, spraying with a 150-fold vinegar solution 3 times can bring them under effective control. Spraying vinegar also has a certain therapeutic effect on flower downy mildew and leaf spot.

However, when spraying vinegar on flowers, the following points should be noted: 1. Be sure to use good edible vinegar, and never use chemically industrial vinegar or spoiled vinegar; 2. The concentration must be strictly controlled and must not be increased at will; 3. Spraying should generally be done in the morning and evening, and be sure never to spray under the scorching sun.
