Yellowing of Chinese Holly
Ilex cornuta varieties of Chinese hollies, especially the popular Burfordi, sometimes produce unusually heavy fruit set. As a result, limbs with the heaviest number of berries often have yellow foliage. This is not due to insect or disease damage, but is caused by a nutritional problem due to heavy demands on the plant. A light application of balanced fertilizer at this time often helps. The most satisfactory solution is to increase the fertility level earlier in the season, starting as plants come into bloom. Following a spring application, apply another in midsummer.
