Tip: Why Does My Plant Have Yellow Leaves?
Watering Issues
-
A good portion of the time, yellow leaves are caused by watering too often. However, some plants can also get yellow leaves when they are underwatered, or watered too infrequently.
-
It is important to maintain ideal soil moisture for your plant. Finding the right balance between watering too frequently or not frequently enough is easier when you know how much of the soil should dry out for your specific plant. Check out our care guides for specific information on how much your plant prefers its soil to dry between waterings.
-
To keep your plant full and lush, water evenly all the way around the pot. Water thoroughly until it drips out the bottom of the pot into the saucer. After a few minutes, discard any excess water to avoid soggy soil and ‘wet feet’ which can lead to root rot.
Improper Lighting
-
Many plants can tolerate low light areas, but if the light is too low, this can cause the leaves to turn yellow. Not enough light means the plant can’t photosynthesize efficiently. This causes growth to slow, meaning the roots take up water much more slowly, and often leads to overwatering symptoms.
-
If you suspect your plant is not getting enough light, try moving it to a spot with bright, indirect sunlight. Bright indirect light can be found next to an east-facing window or a few feet back from an unobstructed southern or western window. If the southern or western window has something like a sheer curtain or natural shade from a tree or building outside, the plant can be placed a little closer.
-
If your plant loves the sun, you may want to acclimate it to a spot with direct sunlight. Direct light is when your plant gets 6 or more hours of direct sun a day. You will find this kind of light next to unobstructed southern or western windows.
Nutrient Deficiency
-
With severe chlorosis, the leaves, affected branches or the entire plant may die. The most common nutrient problem associated with chlorosis is a lack of iron, but yellowing may also be caused by manganese, zinc, or nitrogen deficiencies.
-
If your plant is putting out new growth, fertilize during the growing season. Any balanced indoor plant food with micronutrients should work just fine! Always follow the directions on the label. You can use our nutrition types here
Pests
-
Yellowing leaves could be a sign that there are pests lurking on your plant. Pests such as mealybugs, spider mites, and aphids feed on the sap from your plant’s leaves which weakens the plant and can lead to discoloration.
-
Keep an eye out for signs such as fine webbing, thin black dots or clusters of small white dots on the underside of the leaves, cotton-like tufts, hard bumps on the leaves or stems, and sticky residue on the leaves. If you see any of these signs, start pest treatment immediately. Many plant pests can be treated with neem oil or a spinosad treatment.
Get Your Plant Back on Track
Your plant should be able to recover once you figure out the culprit that is causing the yellowing leaves. Adjust your care accordingly and prune off any leaf that is more than 50% discolored using a pair of plant snips. Avoid removing more than 30% of the affected leaves at one time. Pruning the leaves can help your plant focus its energy on new and healthy growth.
