1. Lack of light

Lack of light is often the cause when money tree leaves turn yellow, according to indoor plant expert Vladan Nikolic of Mr Houseplant. ‘Insufficient light will turn the leaves of your money tree yellow,’ he says.

‘This happens because the plant can only support a certain amount of leaves with the amount of light that it has. If your money tree isn’t getting enough light, it won’t have the energy to support all leaves, so older leaves will turn yellow and die. To prevent this, give your plant plenty of bright, indirect light. If you can’t meet its light requirements with natural light, consider buying a grow light.’

Note that too much direct sunlight can cause a problem but leaves won’t be yellow. ‘The leaves of a money tree plant that hasn’t been properly acclimated to direct sunlight will be burnt and turn brown,’ says Vladan. ‘Sun-damaged leaves can also bleach out and become pale.

‘To prevent sunburn, give your money tree plenty of bright, indirect light, and gradually acclimate it to direct sunlight,’ he recommends.

2. Under or overwatering

Fail to meet a money plant’s water requirements and leaves can yellow. ‘Overwatering can cause a money tree’s leaves to turn yellow, leading to root rot and depriving the plant of oxygen,’ explains plant expert Stephen Webb of Garden’s Whisper.

‘When you water the money tree too frequently or use too much water at once, the roots can become waterlogged, making it difficult for them to breathe correctly. As a result, the leaves start to turn yellow, and the plant’s overall health deteriorates.

‘To avoid this let the top inch or two of the soil dry out before watering again. Stick your finger into the soil; if it feels dry at that depth, it’s time to water. When you do water, give the plant a thorough soak, allowing the water to reach the roots properly. Allow any excess water to drain so the roots don’t sit in standing water.’

Think soil, too. ‘It’s essential to use a good potting mix with large particle amendments, such as perlite, to improve drainage and aeration of the soil,’ says Vladan Nikolic. ‘You should also use a pot with drainage holes, so any excess water can flow out.’

Bear in mind that underwatering can also cause a problem, so be aware of how often to water a money tree and use the technique above to get it right.

3. Pests

The presence of pests can result in yellow leaves. ‘Pests that can turn a money tree’s leaves yellow include spider mites, mealybugs, and aphids,’ says Stephen Webb. ‘These pesky critters can suck the plant’s sap, causing the leaves to lose their natural green color and become yellow or discolored. Moreover, they may leave behind a sticky residue or webs, which can further harm the plant.

‘To deal with these pests, you’ll want to take action promptly. Start by isolating the affected money tree from other plants to prevent the infestation from spreading. Next, inspect the leaves and stems closely to identify the specific pest. Once you’ve pinpointed the culprit, you can try different methods to control them. For example, you might gently wipe the leaves with a damp cloth to remove the pests physically. Alternatively, using a mild insecticidal soap or neem oil spray can help combat the infestation. Regularly inspecting your plant and acting quickly can prevent the problem from becoming severe.’

Should you remove yellow leaves from a money tree?

If your money tree has yellow leaves, you should get rid of them. ‘Remove yellow leaves from a money tree to promote its health and aesthetics,’ says plant expert Stephen Webb. ‘Yellow leaves are a sign of stress, and they won't recover on their own. Leaving them on the plant can drain valuable energy and nutrients from the healthy parts of the tree.

‘To properly remove yellow leaves, follow this simple procedure. First, identify the affected leaves and trace their stems back to the main branch. Then, using clean and sharp pruning shears, make a clean cut as close to the main branch as possible without damaging it. Dispose of the yellow leaves away from other plants to prevent pests or diseases from spreading. Regularly inspect your money tree for new yellowing leaves and repeat the process.’

Over or underwatering are frequent reasons why money tree leaves turn yellow, but if you don’t like the idea of putting your finger in the soil to check, try this trick from Vladan Nikolic. ‘The easiest way to know when to water your plant is to use a chopstick,’ he says. ‘Take one and stick it into the soil, all the way to the bottom of the pot. Pull the chopstick out and if the top 2 inches are fully dry, without any soil stuck on them, water your plant.’
