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. In erect varieties of blackberries, the fruits may become hard and dried, rendering them inedible, said Bell.
Gooseberries can exhibit browning if sunburned.
Grapes rarely get sunburned except if leaves are removed late in the season, exposing previously shaded grapes to full sun. The best way to prevent sunburn is to know your plants' requirements for sun or shade before you plant them, then plant them in the right place, said Bell. But, if they are already in the ground and are getting sunburned, either transplant them to a better site or amend heavy soils with compost so the plant can develop better roots. Make sure your plants are getting enough water and fertilizer for optimal health and minimal stress. A short-term solution for sunburn might be to protect them with a shade cloth.
