Why is My Lily of the Valley Turning Yellow?
Yellowing lily of the valley plants may be an alarming sight if you’re new to growing them, but yellow lily of the valley leaves doesn’t always spell disaster. In fact, if it’s getting close to the end of the growing season, it could simply indicate that your plant is going dormant to prepare for its grand entrance next year. Even though lily of the valley are pretty tough plants, they do sometimes get sick, so if the timing seems wrong or you notice other signs that might point to a sick plant, consider these common causes of yellow lily of the valley leaves: Rusts. Rust problems often start out as yellow spots with rust-colored fungal spores on the underside of the leaf. This fungal disease looks pretty serious, but if you catch it early, you can treat it with fungicide, and it will clear up. Just make sure to alleviate conditions that favor fungal growth, like overcrowding and overly wet soil. Foliar nematode. If just the areas between the veins are turning yellow, before ultimately turning brown, you may have a problem with foliar nematodes. These buggers are hard to get rid of, so the best bet is to destroy infected plants. In the future, don’t water the leaves of your lily of the valley to discourage foliar nematodes from invading. Stem rot. When your lily of the valley has yellow specks on the surface of its leaves, it could point to stem rot. Spots may be yellow or grayish, but they’ll quickly turn brown as the fungus spreads to the crown. There’s no way to save this plant, unfortunately, so it’s best to discard it and either sterilize the soil around it or discard that as well so you don’t spread the fungus.
