What should I do if the leaves of the flowers turn yellow?

In the process of growing flowers, improper management can easily cause the leaves to turn yellow, which has a great impact on the growth of flowers and the appearance of the plants. So what should we do if the leaves of the flowers turn yellow? Let’s learn more about it below.

1. Light causes

Each plant has different requirements for light. If it is a flower plant that likes to grow in a cool environment, then it should not be placed in a location where the light is too strong. If the leaves turn yellow due to excessive light, you need to adjust the lighting. On the contrary, if the leaves turn yellow due to insufficient light, the flowers should be moved to a sunny location.

2. Timely water control

Water the flowers and plants frequently. Once the soil in the pot is too wet for a long time, the soil and air will not communicate well, which will cause oxygen deficiency in the soil, causing root rot at the roots of the flowers and plants, and causing the leaves to turn yellow and fall off. If you find that the leaves and flowers turn yellow due to over-watering, you need to water sparingly and ventilate the soil in the pot in time to promote water evaporation.

3. Improper fertilization

When applying top dressing to flowers, people often choose nitrogen, phosphorus and potassium compound fertilizers , biological organic fertilizers , farmyard manure, etc. When the applied farmyard manure is not fully decomposed, it will continue to ferment in the soil and produce organic acids and heat, which will affect the normal nutrient absorption of the flower roots. The roots cannot absorb nutrients normally, resulting in yellow leaves. Yellowing of leaves caused by fertilization requires lowering the concentration of the solution in the soil. By increasing watering, the water can dilute the excessive fertilizer , alleviate damage to the plants, and promote recovery of the leaves and flowers that are less damaged.

4. Soil compaction

Flowers do not like compacted soil. Compacted soil has poor air permeability, lacks oxygen, and the roots cannot grow normally. Most flowers prefer acidic soil to alkaline soil. When the soil environment is poor and seriously unsuitable, it will cause the death of flower plants. Improve the soil and adjust the soil pH to below 7 and above 5.8, which is conducive to the growth of flowers. Loosen the soil in the garden to break up compaction.

5. Pest and disease damage

Flowers are relatively prone to many diseases and pests, including underground pests, which will chew off the roots and easily cause the leaves to turn yellow. For example, mole crickets and white grubs can be applied with cypermethrin or matrine aqueous solution during watering to kill the underground pests.
