Others prefer a partially shaded site. Newly planted plants or young plants with underdeveloped root systems are particularly susceptible to sunburn. Their water requirements are at a maximum. Also root systems are still developing. If this weren't enough, the days are still long, so plants might have to put up with sunlight for 12 to 14 hours.
Berries can also show signs of sunburn, especially the red raspberry and blackberry.
Drupelets are those tiny round sections that make up a raspberry. These colorless drupelets do not otherwise affect the quality of the fruit, said Bell. You can still eat them. When sunburned, drupelets of trailing varieties can become red and soft and taste overripe. But they still are edible.
