Sudden browning makes me wonder if dog urine is at fault? Dogs love boxwoods and once they start urinating on them, they keep returning because of the smell. The salts in dog urine can burn the foliage and even affect the inner leaves. If you are sure dogs aren't able to access your boxwoods, I'd dig one up and check the root system. If the soil doesn't drain well the plants can suffer from root rot. Rotted roots will be black or brown and possibly mushy. Healthy roots will be creamy white inside; diseased or dead roots will be brown or rusty colored. If the roots look okay, replant the boxwood and water it well to help settle the soil. Hose the plants off well to dislodge any insects and/or urine residues. The only other things I can think of that might affect boxwoods in this way is overspray from herbicides or over fertilization. Hope this information helps you determine just what might be causing the problems with your boxwoods.
