What are the reasons for a cactus turning yellow? Explained clearly in one article

More and more people are growing cacti, and some flower lovers find their cacti turning yellow without knowing why. In fact, the reasons for a cactus turning yellow are mainly too much watering, too great a temperature difference, going too long without watering, and waterlogged potting soil. Let's take a look together below!

Yellowing caused by too much watering

Your watering frequency is too often; watering once every half a month is plenty.

Yellowing caused by unsuitable temperature

When overwintering a cactus, it is best not to let the temperature fall below 10 degrees; being below this temperature for a long time will cause it to turn yellow. You can use wire and plastic film on a windowsill to create a closed space with high temperature and high humidity. Under such conditions, most cacti not only grow fast but also have a crystal-clear color.

Yellowing caused by waterlogged potting soil

For potted cacti, the soil should be sandy soil or sandy loam with good drainage and aeration and containing calcareous material. You can dig some soil from a flower bed in the city, then mix in sand at a ratio of garden soil to sand (3-4:1), and apply a diluted, fully decomposed liquid fertilizer once every 10 days to half a month; do not fertilize in winter.

Yellowing caused by going too long without watering

If you go too long without watering, a cactus will also turn yellow. There is no need for me to say more about the solution, right!
