When the leaves of a money tree turn yellow while the veins remain green, it’s often a sign of chlorosis. Chlorosis is a condition where the plant’s foliage creates insufficient chlorophyll, the green pigment that plants use to convert sunlight into food. This can result in the leaves becoming pale or beginning to yellow.
There are several potential causes of chlorosis:
- Overwatering or Underwatering: Both can cause yellowing of the leaves. The top 1-2 inches of soil should be allowed to dry out between watering.
- Too Much Light or Not Enough Light: Money trees prefer bright, indirect light. Too much direct sunlight can cause yellowish patches to appear on the leaves, while not enough light can cause the leaves to turn yellow or become discolored.
- Inconsistent Temperature or Low Humidity: If your money tree is located near a heating vent, air conditioning unit, or a drafty window or doorway, temperature fluctuations could cause yellow leaves. The plant prefers consistent warm temperatures between 65 and 85 degrees. Also, money trees are native to the tropics and prefer a humid environment. Dry conditions or blowing air from ventilation systems can cause the leaves to get crispy brown edges before wilting and dropping off.
- Pest Infestations: Common houseplant pests like spider mites, mealybugs, and scale can damage your money tree, causing leaves to turn yellow.
- Nutrient Deficiency: Especially a lack of certain nutrients, like iron or magnesium, can cause the leaves to turn yellow.
If you notice the yellowing and green veins are spreading or the condition of the plant is worsening, it might be a good idea to consult with a local nursery or extension service. They can often provide advice based on a physical examination of the plant or even a soil sample. Good luck with your money tree! 🌱
