Q.Yellow leaves on ivy plant
My ivy houseplant, which has been growing fine for the last year, now has many yellow leaves. Am I watering it too much or not enough? I water it once a week. It is a tall plant that grows along a piece of wood. Or maybe it needs to be repotted in a bigger pot. I am not good with plants so I really have no idea. Thanks for any tip you can give me.
Yellow leaves can be caused by a number of things. Typically in houseplants, it is either underwatering or overwatering. Water when the top of the soil feels dry, but to do let the soil dry out all the way. It may also need repotting if it's becoming rootbound, though they normally like being somewhat crowded. That said, if roots are too constricted, this would make it more difficult for the plant to take up water or nutrients. You can check the roots to see if this is an issue or not.
