What Causes the Yellowing of长春花 Leaves
Abstract: This article introduces the related information about why the leaves of长春花 turn yellow, with a detailed explanation below.
What Causes the Yellowing of长春花 Leaves
Changchun flowers, also known as marigolds or "daily new," not only have high ornamental value but also have medicinal effects such as clearing heat, reducing inflammation, cooling blood, and lowering blood pressure. Changchun flowers enjoy sunlight and warmth, have low requirements for water and fertilizer, are easy to care for, and are common houseplants. However, we need to avoid yellowing of the leaves caused by issues such as soil, watering amount, and fertilization during the care of Changchun flowers.
Why Do Changchun Flower Leaves Turn Yellow
Changchun flowers, also known as marigolds or "daily new," not only have high ornamental value but also have medicinal effects such as clearing heat, reducing inflammation, cooling blood, and lowering blood pressure. They enjoy sunlight and warmth, have low requirements for water and fertilizer, are easy to care for, and are common houseplants. However, we need to avoid yellowing of the leaves caused by issues such as soil, watering amount, and fertilization.
1. Changchun flowers thrive in slightly acidic soil. Planting them in soil of other properties can cause their leaves to turn yellow and fail to produce flower buds.
2. Changchun flowers are drought-resistant and dislike excessive moisture. Overwatering can inhibit root respiration. Insufficient watering or long-term water deficiency can prevent the roots from absorbing enough water, causing the leaves to turn yellow and fall off.
3. Changchun flowers require an appropriate amount of nutrients. If fertilized too much, the excess fertilizer can cause residues, making it difficult for the plants to absorb nutrients, resulting in slow growth and yellowing leaves.
What to Do When Changchun Flower Leaves Turn Yellow
1. If the soil is too alkaline and causes yellowing of Changchun flower leaves, it is necessary to change the soil promptly, replacing it with acidic, humus-rich, and loose soil, or adding ferrous sulfate solution to the soil.
2. When excessive watering causes yellowing of Changchun flower leaves, it should be placed in a well-ventilated area to dry the moisture in the soil. When insufficient watering causes yellowing, it is necessary to spray water to supplement moisture, and after recovery, water appropriately.
3. If excessive fertilization causes yellowing of Changchun flower leaves, it is immediately necessary to increase the watering amount to dilute the excess fertilizer in the soil. It is important to water the next day after fertilization to promote nutrient absorption.
