Sun scald

The temperature required to wake up a tree depends on plant species and length of day, but it is typically just above freezing.

When sun scald appears on trees it is most frequently a result of reflected light off the snow during winter months.

The leaves of the tree are also affected by sun scald, particularly on a bright sunny day following a period of warm cloudy humidity.

This is the case if the defenses of the fruit are too heavily inflicted, which may occur when the outer skin is damaged to the point that the cell walls/membranes are either gone or weak enough for the plant's enemies to penetrate.

Sun scald often presents as more of an internal damage, with the affected tissue gaining a leathery or wrinkled appearance and a pale discoloration.

[3] Fruits damaged to either extent are usually considered unmarketable due to diminished appearance, taste, and texture, but those of the latter are sometimes sold at a lower grade or utilized as an (often puréed) ingredient.

Reducing the amount of light the tree is exposed to by planting a shrub or bush strategically to shade the southwest side can be less effective than wrapping or painting, but can have better aesthetic qualities for landscaping.
