My plant's leaves are turning yellow. Do I need to fertilize it?Updated 3 years ago

Maybe. Have you fertilized it in the last month during the growing season? Is the soil old and needs to be repotted, or the soil may have accumulated salts from the fertilizer and need a reboot. But most of the time, moisture stress is the culprit to yellowing leaves. Too much water or not enough can turn the leaves yellow with distress. So hurry and find your 3 in 1 plant meter and stick the prongs down deep to see what's going on beneath the surface. You can't tell what's going on beneath the surface, and a good manicure won't allow you to check at their roots with your finger.

Plants will protest if the temps around them get too cold. We turn blue when we're cold; they turn yellow!

Plants may not 'walk on sunshine,' but they want enough to keep the photosynthesis going. Low light conditions can make them feel bad and lose their leaves, especially if their soil is too moist in combination with the low light.

One more thing. Leaves age and say to themselves, "The rest of you guys have it here; I've done my job photosynthesizing and fed this plant well. I'm checking out." That is a regular occurrence. While new leaves grow, old ones go low (drop off.)
