What is the reason why the leaves of the Brazilian cycad turn yellow?

The Brazilian dracaena is a common ornamental green plant. During the maintenance process, its leaves will easily turn yellow, which will affect its growth and reduce its ornamental value. So what is the reason why the leaves of the Brazilian dracaena turn yellow? Let’s take a look with the editor below.

1. Too much light

The Brazilian dracaena is a flowering plant native to Africa and is often planted as an ornamental foliage plant. So why do the leaves of the Brazilian dracaena turn yellow when planted? The yellowing leaves of the Brazilian dracaena may be caused by excessive light. At this time, it is best to transplant the plant to a semi-shaded place for a period of time. After the plant recovers, it can receive appropriate light.

2. The soil is alkaline

The Brazilian iron tree likes to grow in slightly acidic soil. If the soil is alkaline, the roots will find it difficult to adapt, causing growth problems and the leaves will turn yellow. You can change the soil to provide new soil. You can also use 500 times diluted ferrous sulfate solution to water the potting soil about once a week. Continuous watering for several times can alleviate the yellowing.

3. Improper watering

① Lack of water

The Brazilian iron tree likes to grow in a high temperature and humid environment and has a high demand for water. If the plant is watered too little during planting, the lack of water will also cause the leaves to turn yellow. At this time, you need to water the soil appropriately and water it thoroughly, but try not to leave water stagnant. When planting later, you can water the plants according to changes in the soil or seasons.

② Excessive watering

Although the Brazilian dracaena needs water, if you water it too much, the roots will not be able to absorb it normally, and the leaves will turn yellow. You need to stop watering immediately and loosen the soil in time to promote water evaporation.

4. Improper fertilization

① Lack of fertilizer

During the growth of the Brazilian iron tree, certain nutrients are needed to support its growth. If there is no nutrient supplement for a long time, the leaves will turn yellow. Just add fertilizer according to the growth trend and pay attention to the concentration.

② Excessive fertilization

The demand for fertilizer of the Brazilian dracaena is not high. If too much fertilizer is applied during cultivation, the roots of the plant will rot, the leaves will turn yellow, and in severe cases, the plant will die. At this time, you need to pour a lot of water into the soil to dilute the fertilizer. After that, when cultivating, you only need to fertilize the plants appropriately during the growth period, and the amount of fertilizer applied each time should not be too much.

5. Impact of pests and diseases

Due to improper maintenance methods and the influence of diseases and pests, the leaves of the Brazilian dracaena may turn yellow. Ventilate regularly for prevention, and spray medicine according to the specific condition after the disease occurs.
