There are many reasons for the yellowing of the leaves of the rich tree. If it is caused by water shortage, it will increase the watering. If it is caused by too much watering, it will reduce the watering. If the light is too strong, it will reduce the light. If it is lack of fertilizer, it will increase the amount. Fertilizer, if it grows too lush, it will pruning and cutting leaves.
Reason one: improper watering
Rich trees like a warm and humid climate, too much or too little water will cause the leaves to yellow. Too much watering, the soil in the basin is often too wet, the roots of the tree are not smooth, the roots rot, and then gradually spread to the branches, and finally the leaves turn yellow, withered and shed, and the whole plant dies when severe. If the watering is too little, the soil on the potting soil will be dry and dry, which will not only affect the absorption of nutrients, but also cause the leaves to be dull and dull, and gradually fade from the bottom to the top, and the tree will be silently protesting against your laziness~
Solution: ventilate, turn basin or hydrate in time. When there is too much water, put it on the window and do a good job of ventilation. If the potting soil cannot be dried in a short time and it is muddy, you can put a layer of absorbent cotton cloth on the bottom of the flower pot. If it is wet, it will be replaced with a new one, or blow it with a fan. If you use all the methods and the soil does not dry out, then change the soil.
When the watering is too small, the surface of the soil is cracked, and in the case of not all yellowing, the hydration is gradually performed. Wet the surface of the soil first, pour a little one hour, and gradually pour water. Avoid watering the water at one time to prevent the roots from swelling and affecting growth.
Reason 2: Improper lighting
xx The fortune tree likes the sun, but it is not resistant to direct sunlight. The sun or the long-term shade will also cause the leaves to be yellow. Putting the fortune tree in the corner of the room, paying too much attention to the viewing effect, causing the rich tree to be in a shaded environment for a long time, will cause the new leaves to grow yellow and long, the old leaves are dull and a lot of falling off. Summer is hot, you can only blow air in the house, how can the rich tree survive the impact of the sun. If you forget to move it to the shaded place at noon, you can only accept the yellowing of the leaves.
Solution: Move to the semi-shade. For the sudden acceptance of the sun, resulting in the yellowing of the leaves of the rich tree, the chance of saving is not great. The leaves are yellow due to excessive exposure, and the moisture of the leaves is highly volatile. It is difficult to recover in a short time. It is recommended to move to the semi-shade. Appropriate watering, yellowing leaves will slowly fall off, to grow sprouts.
Reason three: too much fertilizer
You must be afraid of the rich tree, the lack of fertilizer to become malnourished, right? But excessive fertilization is not good either. The nutrients absorbed by the rich tree are quantitative. If the fertilizer is excessively applied and the plant absorbs sufficient nutrients, the remaining fertilizer will burn the roots of the tree, which will cause the leaves to yellow.
Solution: Rooting and changing soil. Too much fertilization leads to the decay of the roots of the tree, the plants are removed, the decayed parts are cleaned, replaced with new soil, and replanted. Or by watering, dilute the nutrients in the soil and reduce the fertility.
Reason four: temperature is not
Some people hate summer and winter, because a temperature is too high, a temperature is too low, in fact, plants are also like this, the suitable temperature for the growth of rich trees is 20 ° C ~ 30 ° C, too high or too low will affect its growth. If the temperature in the growing environment of the rich tree is too high, the transpiration is too strong, the water and nutrient supply in the roots are insufficient, and the leaves will gradually dry and yellow. However, if the temperature is too low, for example, if the temperature in winter is lower than 16 °C, the leaves will easily yellow and fall off, and it will easily die below 10 °C.
Solution: Acidify the soil. The rich tree is suitable for growing in acidic soil, and changing the acidity and alkalinity of the soil in time can remedy the yellowing of the rich tree. There is no need to remove the basin, no need to change the soil, only need to apply a certain amount of ferrous sulfate in the soil, directly sprinkle it in the flower pot, which can increase the soil fertility and acidify the soil, killing two birds with one stone.
Pay attention to the process of acidifying the soil, do not use vinegar. Vinegar can indeed make the soil sour, but because of the radical change, it will damage the organic matter in the soil and will lower the fertility of the soil.
How to prevent yellowing of leaves?
Control the amount of water
In order not to let you cry because the leaves of the rich tree are yellow, we must do everything when it is not yellowed, first grab the amount of watering. Watering the tree for wealth should follow the principle of “do not dry, water, and pour through”. Under normal maintenance, you can pour water once every 15 to 20 days.
Keep your fortune tree and do your best every day. From the end of April, choose a sunny and warm noon, move it to the outdoor or balcony, receive the sun, start for 1-2 hours, then gradually extend the time. You will receive unexpected results. Of course, in summer, it is best to put time in the morning or evening. At this time, the sun is mild and will not cause damage to the tree.
Fertilize the rich tree, follow the principle of “thin fertilizer and diligence”, fertilize according to the growth of the plant, apply liquid fertilizer or mixed flower fertilizer every 1 to 2 weeks in the growing season, and add it when the plant is changed. Decomposed base fertilizer.
Control soil pH
xxxx Cause: If the ambient temperature of its growth is too low, or too high, to make it uncomfortable, it is also prone to this problem.
Treatment: Adjust the temperature around it and try to control it between 20 and 32 °C.
