Potted gardenia did not do a good job of yellow wilting of leaves at 3 points.

Can not only do bonsai play, but also when potted cultivation, the most suitable for family balcony planting. However, flower friends in the maintenance process, often encounter gardenia leaves "yellow wilting" phenomenon, in fact, it is because 3: 00 did not do a good job.

1. Irrational watering leads to iron deficiency

Gardenia jasminoides is an acid-loving plant, so it is not suitable to irrigate alkaline water for a long time, otherwise it will easily lead to the lack of iron that can be absorbed and utilized by roots in the soil and affect the synthesis of chlorophyll. The color of the leaves will gradually change from green to yellow, and in severe cases, the whole leaves will become yellow-white to white, and wither and fall off on their own.

At this time, flower friends can combine to fertilize gardenia and alternately spray liquid fertilizer and 0.1% ferrous sulfate solution to control gardenia. Generally every half a month, three times in a row, the symptoms of yellow leaves can be relieved. Adhere to the use, can reduce the problem of yellow leaves of gardenia.

3. Gardenia is magnesium deficient.

When the gardenia is magnesium deficient, the veins of the lower old leaves first lose green and yellowing. In order to prevent this phenomenon, flower friends in the process of fertilization, less potassium fertilizer and ammonium fertilizer, because they will have an antagonistic effect with magnesium ions, resulting in the loss of magnesium. The correct method is to apply alum fertilizer and water frequently, apply flower organic liquid fertilizer for 2 or 3 times after budding, and then dilute it by 500 times.
