If you’ve noticed your plant leaves turning yellow, it’s likely a call for help from your leafy friend. Yellowing leaves, though common, can be worrisome, especially when you’re unsure about the cause or solution. But fear not—understanding why leaves change colour and learning how to fix yellow leaves on plants can breathe life back into your greenery. Here’s a rundown of the main culprits behind yellow leaves and what you can do to restore your plant’s lush, green vitality.
Overwatering or Underwatering: Getting the Balance Right

Water is crucial to a plant’s survival, but both overwatering and underwatering can turn leaves yellow. If you’re giving your plant more water than it needs, the roots may start to rot, depriving the leaves of nutrients and causing them to yellow. Conversely, too little water can leave your plant dehydrated, leading to similar symptoms.
How to Fix It: For plants prone to overwatering, use well-draining soil and pots with drainage holes to prevent water from sitting at the roots. Check the top inch of soil; if it feels dry, it’s time to water.
Inadequate Sunlight: Finding the Sweet Spot

Just as plants need water, they also require the right amount of sunlight. Yellow leaves are often a sign of insufficient light, which hinders the plant’s ability to perform photosynthesis efficiently. In low light, plants may weaken, and their leaves will start to yellow.
How to Fix It: Observe your plant’s light requirements—some need direct sunlight, while others thrive in indirect or low light. If your plant looks shadowed, relocate it to a brighter spot or consider artificial grow lights, especially during shorter days in colder months.
Nutrient Deficiency: Feed Your Plant Right

Plants, like humans, need a balanced diet to stay healthy. When they lack essential nutrients like nitrogen, potassium, or magnesium, leaves can turn yellow. Nitrogen, for instance, helps plants maintain lush green foliage, and without it, leaves lose colour and eventually die off.
How to Fix It: Introduce a balanced fertilizer tailored to your plant type, either in liquid form or as slow-release granules. Be careful not to over-fertilize, as too many nutrients can burn the roots and cause even more yellowing.
Pests and Diseases: Watch for Unwelcome Guests

Tiny pests such as aphids, spider mites, and mealybugs, or fungal infections, can stress your plant, turning leaves yellow. If left unchecked, these invaders can spread quickly, affecting the entire plant or even neighboring ones.
How to Fix It: Regularly inspect your plants, especially under leaves where pests like to hide. For minor infestations, try a gentle insecticidal soap or neem oil spray. If the problem persists, isolate the plant and treat it thoroughly. With fungal issues, consider removing the affected leaves and improving air circulation around your plants.
Ageing Leaves: A Natural Process

Sometimes, yellowing is simply part of a plant’s life cycle. As new leaves grow, older ones naturally turn yellow and drop off. This isn’t necessarily a bad thing but rather a natural progression in a plant’s growth.
How to Fix It: Simply prune off the yellow leaves to encourage fresh, healthy growth. This cleanup allows your plant to focus energy on new leaves and maintain a tidy appearance.
So, whether you order plants online or shop from the market, don’t forget to address the root cause of yellow leaves. You’ll not only revive your plant but also enjoy the satisfaction of nurturing a healthy, green space in your home. A little extra attention can go a long way in transforming your plant-care journey into a flourishing success.
