The leaves on some of my caragana shrubs are yellowing. They have been planted for about 3 years. I haven't watered them much this year but it has been raining alot. Could this be too much water or not enough? Or the mineral content of the soil? There are 5 shrubs and only 2 are yellowing. What shall I do?

Caragana is also known as the Siberian Pea Shrub, a hardy plant for poor sites. It will grow in any soil, in full sun or part shade, and will tolerate droughty conditions. Caragana will grow quickly to 15-20 feet high with a 12-18 foot spread. They are susceptible to a fungal leaf blight, which may be a result of your rainy spring. You can cut the stems back without hurting the plant, and dispose of the infected stems and leaves. This will keep the disease from spreading to other healthy plant parts. There are no chemical controls for the leaf blight. Prune your shrubs to remove the diseased parts and open them up to better air circulation.
