The reason why the leaves of Brazilian cycad turn yellow

1. 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.

2. Too dry

The growth of the Brazilian iron tree requires a certain amount of water supplementation. If it lacks water for a long time, the soil in the pot will become too dry, causing the leaves to turn yellow. Water needs to be applied in time according to the growth status, but not too much water at one time.

3. Too much watering

Although it 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. Lack of fertilizer

During the growth of the Brazilian iron tree, certain nutrients are needed to support its growth. This phenomenon will also occur if there is no nutrient supplement for a long time. Just add fertilizer according to the growth trend and pay attention to the concentration.

5. Pests and diseases

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