I installed several leather leaf mahonias last fall. The foliage on the plants (not all the leaves, but many) has changed from green to a yellowish tone. Is this normal, or is the plant experiencing stress? How should I treat the problem if there is one? Thanks

The plants seem to be stressed. Droughty soil or soggy wet soil both can kill roots and cause stress. Dig down a few inches and feel the soil to see if it is dry or soggy or just right. Spread one cup of lawn fertilizer (NOT a weed and feed) in a 4X4 foot area around each plant and water it in well. Then apply a mulch around the plants to hold moisture and keep weeds away.
