The most prominent symptom of Sever's disease is heel pain which is usually aggravated by physical activity such as walking, running or jumping. The pain is localised to the posterior and plantar side of the heel over the calcaneal apophysis.everâs disease is self-recovering, meaning that it will go away on its own when the foot is used less or when the bone is through growing. The condition is not expected to create any long-term disability, and expected to subside in 2â8 weeks.
Site Selection. Most holly shrubs and trees prefer a full-sun to light-shade location with moist soil that drains well. Varieties such as American holly (Ilex opaca: USDA zones 5 to 9) and yaupon holly (Ilex vomitoria; USDA zones 7 to 9) are versatile and shade-tolerant.
Spread a 3- to 4-inch layer of mulch over the ground, surrounding the holly tree to improve the soil's moisture retention and deter the growth of competitive weeds. Allow about 3 inches between the plant's crown and the mulch to prevent rotting caused by poor air circulation.
