Hemophilia (heem-o-FILL-ee-ah) is a rare bleeding disorder in which the blood doesn't clot normally. If you have hemophilia, you may bleed for a longer time than others after an injury.
Aphids: There are five species of aphids commonly found on apples: apple grain aphid, rosy apple aphid, apple aphid, spirea aphid and the woolly apple aphid. The aphid species can be identified by their color, the time of year when they are present and by differences in the cornicles, which are small paired projections from the rear of aphids.
Apples are one of the most cold-hardy fruit producing trees, as they bloom late in the spring, avoiding frost damage. Currently, 7,500 varieties of apple trees are grown worldwide. According to Fruit-Trees, most apple tree varieties are rated for hardiness zones five through eight. However, some varieties are hardy in zone four and zone three.
