Gardenia yellow leaves dry leaves and do not bloom The culprit here knows that you can also raise well
Today, a flower friend asked me how to fix the yellow leaves of gardenia and sent me a picture. I just sent it here for everyone to have a look at.
In the picture, the dried leaves are first cut off and sprayed with water at the ratio of mancozeb 1 to water 800 or methyl topiramate to water at the ratio of 1 to 1000, once every 7-10 days, usually about three times.
Gardenia jasminoides flowers were watered with ferrous sulfate 1RU 1000. The potted soil was thoroughly dried until the yellowing of the new leaves did not stop, and ferrous sulfate could be irrigated once a month or so.
Leaves dry, falling, from the picture is now more serious, this is the performance of leaf blight and downy mildew, gardenia potted impervious basin, coupled with stone paving, indoor breeding ventilation effect is not good, the root is in an impervious environment for a long time, the soil is too wet will easily cause downy mildew and leaf blight, if you regularly spray carbendazim before the onset of the disease will not occur. Gardenia is a flower in the south, like acidic soil, the lack of acidic substances in the soil, the main performance is green veins, yellow in other places, the picture obviously shows a lack of iron, so it is necessary to timely supplement iron, let him restore growth, and wait for the leaves to stop yellowing and restore green before they can grow normally. In the process of cultivating gardenia, it is the best way to supplement ferrous sulfate solution once a month or so. On the contrary, it is easy to happen.
Why don't gardenia blossom? Now the two situations of gardenia are the main reasons for not blooming. After the plant resumes normal growth, pay attention to a few points in the maintenance process, make sure to blossom every year, during the growing season, apply ferrous sulfate once a month or so, spray carbendazim once a month when entering the house in winter, except for appropriate shade in summer, maintain all-day sunshine in other seasons, provide fertilizer and water once or twice a month in the growing season, plant with loose and breathable pots and soil, and the soil surface can be watered thoroughly.
