If discover yellow should stop watering, loose soil, let its ventilation and dry.

1.施肥不当:在盆花生长期,长期不施肥或施肥不足等,会引起叶黄现象;施浓肥过多,花吸收不了把根烧伤,不能吸收水分同样会引起叶黄凋落,夏季每周施一次稀薄肥,切勿多施浓肥。若施肥过多,可多浇水稀释并冲去土壤中肥分。缺肥时可导致盆土板结,花叶黄、薄、瘦,枝条细长黄嫩。应立即施肥,一周内见效,可按期施肥,使花正常生长,开花多。

Improper fertilization: growing up in potted flower, no fertilizer or lack of fertilizer for a long time, can cause leaves yellow phenomenon; Strong fertilizer overmuch, flowers can't absorb the root burns, cannot absorb the moisture can also cause yellow leaf litter, fat thin summer shi once a week, don't do much concentrated fertilizer. If too much fertilizer, water more can dilute maps and rushed to the soil. When lack of fertilizer can cause the soil harden and Mosaic yellow, thin, thin, branches slender Huang Nen. Should immediately fertilization, work in a week, but fertilization on schedule, make the flower to normal growth, flowering.

The temperature is too high: high temperature in summer season, cool sex xi Yin flowers in the high temperature resistance, strong light, easy to cause the young leaf blade tip or edge withered leaves, encounter this kind of situation should be timely will be moved into the shade and ventilation, water cooling, increasing humidity advantageous flowers grow.

Air drying: cultivation in the north of some flowers or humid air environment. Such as camellia, orchid, the air is too dry often lead to tip dry, leaf withered or blade on the focal spot. Edge curl corrugate get tan and other symptoms. Especially with coal fire, that could be played indoors during the winter heating heating area heavy disease, at this time should be used and room temperature close to the water spray leaves, in order to increase the air humidity, family summer flowers on the balcony can sprinkling water on the ground of the balcony, the local environment humid and cooling effect.

6.碱大:由于盆花长期浇水,盆土内积累盐碱,严重时盆土上有碱壳使花叶脱落。方法是换新土或向叶面喷施硫酸亚铁水液中和,使用矾肥水与发酵淘米水,均能取得较好的结果,但切勿多施,如硫酸亚铁施肥过多,叶也黄,但不脱落,此时应适当浇碱性水来调节。

Alkali big: as the potted flower watering for a long time, the soil salinity accumulation, serious when the soil on the alkali shell Mosaic fall off. Method is a new soil or spraying on the leaf ferrous sulfate liquid and water, the use of alum and water with the water that clean out rice fermentation, good results can be obtained, but not much, such as ferrous sulfate fertilizer overmuch, leaves are yellow, but don't fall off, this time should be watering the alkaline water to adjust appropriately.

Branches and leaves too close, luxuriant foliage and uncut for a long time, make the cella foliage illumination is insufficient, appear yellow leaves fall off phenomenon, should strengthen the clip ventilate cella, and proper fertilization.
