Why is my white hosta turning green?
This reversion to green is called viridescence and is a physiological response to warm summer nights. In regions where the nights are cool, the leaf color of ‘Albomarginata’ hosta remains unchanged. Full sun tends to exacerbate the change in color and appearance of the leaves.Click to see full answer. Thereof, why are my hostas turning…

Thereof, why are my hostas turning white?Hostas with a lot of white in them often will “melt out” in too much sun, and this could be described similarly to your problem here. Let us know for sure about the name of your new hostas, and if you could post a picture, that would be a big help. Sound like sunburn.Additionally, what does it mean when hostas turn yellow? When you see yellowing leaves on hosta, the plant may have petiole rot, caused by the fungus Sclerotium rolfsii var. delphinii. The earliest symptoms are yellowing and browning of the lower leaf margins. Other fungal diseases, such as root and stem rot, are generally caused by excessive moisture and are usually deadly. Secondly, why did my blue hosta turn green? Most blue-leafed hostas become green at some time during the growing season when their waxy surface is not as reflective as it once was. The wax seems to almost melt off with exposure to hot sun, harsh watering, or some pesticide sprays.Why do hostas lose their variegation?Variegated hostas are hosta mutations of cells in one or more layers of the leaf. When a mutation occurs, the normal ratio of plastids is rearranged. Some colors become more abundant, and the leaf takes on a variegated look. However, not all hosta mutations are stable.
