## Why is my cactus turning yellow

A yellowing cactus is usually a sign that something isn’t quite right with its growing conditions. While cacti are low-maintenance plants, they are sensitive to overwatering, poor light, and sudden environmental changes.

Identifying the cause early will help you correct the issue and prevent long-term damage.

## Quick answer: why cacti turn yellow

Cacti typically turn yellow due to overwatering, poor drainage, lack of light, or stress from temperature changes. Adjusting watering, improving light, and ensuring well-draining soil will resolve most issues.

## Step-by-step guide to fixing a yellow cactus

Step 1: Check watering levels

- The most common cause is **overwatering**
- Allow soil to dry out completely between watering
- Reduce watering frequency immediately

Step 2: Inspect drainage

- Ensure the pot has **drainage holes**
- Use a **free-draining cactus mix**
- Avoid letting the plant sit in water

Step 3: Improve light conditions

- Move to a **bright location with plenty of light**
- Gradually introduce more sunlight if needed
- Avoid sudden exposure to intense direct sun

Step 4: Check for root damage

- Remove the plant from the pot if necessary
- Look for **soft, dark, or rotting roots**
- Trim damaged roots and repot in fresh compost

Step 5: Stabilise the environment

- Avoid sudden changes in temperature
- Keep away from cold drafts
- Maintain consistent care

## When yellowing is most likely

Yellowing often appears:

- After overwatering
- During seasonal changes
- When moved to a new location
- In low light conditions

Early signs should be addressed quickly to prevent rot.
