If the leaves of your once-thriving have begun to turn yellow, it could be a sign that something is off.

For those who adore their plants, witnessing them lose their vibrant green hue can be distressing. However, there may still be a chance to revive them.

Elise Harlock, a plant expert from Prestige Flowers, has shared her expertise on this common issue and how to restore the health of your houseplants. According to Elise: "It's a sign that something isn't quite right, but the good news is, it's usually easy to fix."

She identifies overwatering, underwatering, and nutrient deficiencies as primary reasons for leaves losing their lustre. "Too much water is the number one culprit," she explains, as excessive moisture prevents roots from accessing oxygen, leading to yellow leaves and potential root rot.

Conversely, Elise warns that inadequate watering can also cause problems: "When plants are too dry, they struggle to take in nutrients, causing their leaves to turn yellow and crisp up at the edges."

Additionally, nutrient deficiencies can contribute to yellow leaves, as plants require a balanced intake of nitrogen, magnesium, and iron to remain healthy and green. Elise has some top advice for keeping houseplants healthy and happy, reports .

She swears by the 'soak and drain' method for watering. "Instead of giving your plant a little water here and there, place it in a sink or bath and water it thoroughly until water runs through the drainage holes," she suggests.

"Let it drain completely before putting it back in its pot. This ensures the roots get enough moisture without becoming waterlogged."

Elise also recommends checking the soil's moisture level before reaching for the watering can. "Stick your finger about an inch into the soil - if it feels dry, it's time to water. If it's still damp, wait a few more days."

But over or under-watering isn't the only issue that might be affecting your plant's health. Elise adds: "Some plants scorch in direct sunlight, while others won't thrive in low light. Make sure your plant is in the right spot for its needs."

She warns that temperature changes and pests like spider mites or aphids can also harm plants. However, don't lose hope at the first sign of trouble. Elise reassures: "A few yellow leaves doesn't mean your plant is doomed. Trim off the affected leaves, adjust your care routine, and you'll often see new, healthy growth in no time."
