Why is your Cactus turning yellow?

1. Large pot size

When it comes to a plant pot, size does matter. The most basic reason for the cactus turning yellow is that it has outgrown its pot. This is the cactus’s way of telling you that it needs space to grow. Just re-pot the plant in a bigger pot and wait for few days.

2. Improper watering

Yes, inadequate watering may be another reason causing the cactus to turn yellow . Both less and more water is bad. Generally, a cactus should be watered bi-weekly.

Waterlogging can make the roots rot and the plant will eventually die. So more water is not equal to more love in this case.

3. Improper potting soil

Cactus loves well-drained soil . The soil should dry up quickly after watering. So, clayey soil (which is tightly packed) may not be suitable for the cactus.

A quick way to check this is, put a wooden stick inside the pot and if it comes out wet, the soil may not be drying up adequately, consider changing it.

Also, if the soil is old consider changing it and fortifying it with fertilizers. Often saturation of fertilizers is the reason for the plan to turn yellow as it is not getting enough nutrition.

4. Wrong Plant Placement

Yes, the cactus is a desert plant but not all species need a full day of direct sun. In fact, the cactus grown in nurseries may not be very fond of the sun. Identify your cactus type and place it accordingly. Also, save the plan from the extreme winter chill.

Experiment with your little spiky by keeping it in direct sun, shade, indirect sun. Keep it where it grows the best.
