Snowball Bush Leaves Are Turning Yellow

Question From: Caldwell, Idaho, United States
Q: My snowball bush's leaves are turning yellow. I have applied urinate in the past when the leaves have turned yellow, but it seems to keep occurring every year. What is causing this. Should I apply more urinate, sulfur, manganese, magnesium???

A: I suggest you get your soil tested before adding all kinds of amendments or peeing on your shrub. Urine washes out of the soil on the first rain.I would use a product such as Espoma Plant Tone or Holly Tone at the recommended rates. Best used in late fall or early spring but it's fine to use it now. It's an organic based slow release fertilizer. The pH of soils vary in different parts of Idaho. Holly Tone is recommended for soils with a hight pH. Best And Happy Yardening, Nancy

Comment: I'm horrified! Spell check changed ironite to urinate. My apologies!!!
