Recently, a flower friend asked, "The climate in the north is dry. How to raise boxwood? " Does anyone know? I planted a batch of green leaves, and then yellowed a batch of leaves. "So, boxwood leaves turn yellow? What's the solution? Next, Uncle Gardener introduced the causes and solutions of yellow leaves of Buxus microphylla. Euonymus microphylla 1. Too much watering or too many seats will lead to yellowing of Buxus microphylla leaves. It is characterized by no obvious change in old leaves and yellowing of young leaves. Solution: control water immediately and reduce watering times. Second, long-term water shortage If you often forget to water plants or suffer from long-term water shortage and drought, these conditions will also lead to yellowing of leaves. Its characteristic is that the old leaves turn yellow first from bottom to top. Solution: Plants should be watered in time. If there is water shortage for a long time, the whole leaf will turn yellow, lose all the light, and even die in the worst case. Populus simonii bonsai excessive fertilization. If the plants are fertilized recently, it may be that the fertilization is too frequent or the concentration is too high, and the roots will burn, causing the leaves to turn yellow. It is characterized by thick, shiny and uneven young leaves. Solution: You can't be fertilized in the near future. When the situation is found, a lot of water should be poured immediately, the amount of fertilizer should be reduced, or the method of changing soil should be adopted. 4. Long-term non-fertilization Due to insufficient fertilizer, low fertilization concentration, long fertilization interval or long-term non-fertilization, there will be no nutrients and yellow leaves; Its characteristic is that the leaves on the tender leaves and stems will turn yellow first. Solution: If this phenomenon is not fertilized in time, the whole plant will wither and even die. For flowers lacking fertilizer, it is forbidden to apply a large amount of thick fertilizer at one time to avoid burning roots. Remember the principle of applying thin fertilizer frequently. Euonymus microphylla V. Insufficient nutrients If plants lack iron for a long time, it will also cause the leaves of plants to turn yellow. Now the flowers at home are basically planted in flowerpots. Yellow leaves often appear because of the great changes in soil fertility conditions.
