Gardenias are beautiful and fragrant, and are loved by more flower friends, and gardenias are also a kind of flowers that are especially willing to bloom in summer. Whenever you put it indoors, you can smell its flowers, and it is a beautiful scenery when you put it outside.
But recently, more and more friends are more distressed, the gardenia at home, there are yellow leaves, the appearance of falling buds, today I will give you a total of a few points, I hope it will help you.
1. The soil remains slightly acidic.
Gardenias, like most southern flowers, are lovedAcidicThe fertile soil is shade-tolerant but equally prefers mild sunshine. The temperature during the growing season is 18-22 degrees Celsius, and it should not be exposed to the sun, otherwise the leaves of the flowers will turn yellow, turn white, and may even fall off.
Keep the soil in good condition, if necessary, you can use acidic substances, such as ferrous sulfate, citric acid, etc., to keep the soil acidic, otherwise the soil will become alkaline, which will prevent the gardenia from absorbing iron, causing its branches and leaves to wither and even die.
However, it should be noted that the watering of ferrous sulfate and citric acid must be fully diluted, only if it is fully diluted, it will be good for the plant, and the higher the concentration, the more harmful it will be to the plant, so you must pay attention.
2. Plenty of sunlight.
Gardenias are very fond of sunlight and warm conditions to grow, so if the gardenia grows outdoors, before summer, the warmer the sun, the better, the more it blooms, the longer it blooms, and the bigger the flowers.
Therefore, if you don't have the conditions to keep it indoors, then you must put it in a place where there is sunlight for a long time, so that it can bloom more, bigger and better in summer. Unlike its flowers, it doesn't have to block it from the sun at noon. Because it is particularly fond of photosynthesis.
Photosynthesis is a key factor in the production of chlorophyll in gardenias, which will send the nutrients needed by the plant to the whole body of the plant, so that the nutrients will circulate. Good for plant growth.
3. Fertilization time.
Gardenia is usually fertilized every 7 days, and the number of fertilization can be appropriately increased during the budding to flowering, and fertilization once in 15 days during the growing season is enough to meet the needs of growth.
Note that potted gardenias are planted for less than three years, do not apply human and animal manure, and when fertilizing, pay attention to less nitrogen fertilizer, you can try to avoid the problem of only growing branches and leaves without flowering.
The flower buds of gardenia are full, the leaves are green, and the flowers are fragrant, no matter where they are placed, they are very beautiful.
