What to do if the leaves of golden diamond have yellow spots

1. Reason

1. Improper watering

If the newly grown leaves are dark yellow and look lifeless, and the branches are thin and shriveled, it means you have watered too much. If the edges of the leaves turn yellow, the old leaves turn yellow and fall off, and the new leaves are relatively normal, it means that you are watering too little.

2. Improper lighting

If the edges of the leaves are dry and broken, and small yellow spots appear on the sunny side of the leaves, it is caused by too strong sunlight. If you place it in a dark area for a long time, it will not get enough sunlight, it will be difficult to grow chlorophyll, and the leaves will turn yellow and fall off.

3. Insufficient nutrients

If the ratio of fertilizer to water is much larger, the flowers will turn yellow, the new leaves will turn yellow-brown, the leaves will be fat but not smooth, and the old leaves will turn brown and fall off. If you often forget to add fertilizer, the young leaves will turn yellow-green and the old leaves will turn from green to yellow. If nitrogen is deficient, the leaves will grow smaller, turn yellow at the lower ends, and the entire plant will become chlorotic. If there is a lack of phosphorus, the veins at the bottom of the leaves will turn yellow. If there is a lack of potassium, the edges of the leaves will turn brown and the plants will easily fall over. If there is a lack of iron, the leaves will develop yellow spots and dry up. In addition, it likes acidic soil. If your home is in the north, the water and soil are alkaline, the leaves will turn yellow or even fall off.

4. Anthrax

If the leaves are attacked by bacteria, small yellow spots will grow, usually on the edges of the leaves.

2. Preventive measures

1. Spray water on the leaves and surrounding areas frequently to help increase the surrounding humidity. It is best to keep the temperature at around 20 degrees. In the winter, wait until the soil is dry before watering, and in the summer, hot weather can help keep it moist.

2. Do not place it under the air conditioner, do not expose it to the scorching sun, and do not place it in a dark area for a long time.

3. If there is too much fertilizer, you should stop adding fertilizer immediately and wash away most of the fertilizer with water. If there is too little fertilizer, the soil will dry out and become lumpy. You need to add some alum water. Normally, you should add light fertilizer frequently, with nitrogen fertilizer as the main ingredient. If the soil is alkaline, you can ferment the rice washing water and then water it into the soil.

4. If it is a disease or insect pest, you must promptly remove the diseased leaves and branches on the tree and buy special pesticides, such as Bordeaux liquid. Spray it once every seven to ten days, and spray it two or three times in a row to prevent it. If the situation is serious, spray it with bacteria and toxin remover. Frequently spraying water to clean the leaves can help prevent insects.
