Potted plants are common in our daily life, often see potted plant leaves yellow, what reason is this? We shandong green seedling base manufacturer below small make up is to introduce you to potted plant leaves became brown what reason be?
Potted plants should right amount water, adhere to the "see dry wet, water is pouring through" principle, such as watering plants is overmuch, easy to cause the soil water for a long time, choked the root rot, can not normal to absorb moisture, resulting in potted plant yellow pages or even fall off. If discover yellow should stop watering, loose soil, let its ventilation and dry.
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.
The small flower big basin: root system, because of the large flowers need more water, small bowl doesn't satisfy the need flowers grow, then old leaves often dry yellow without luster, leaves yellow, thin appropriate basin, you want to change the soil to add 3 0% humus soil make normal growth.
Lack of water, flowers, such as lack of blade droop, should move quickly to spray water on blade, to speed up the plant to absorb moisture, and then water into the basin, the attention to less water to soil moisture, water more do not.
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.
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.
