During summer, Blackjack oak should be maintained below 77℉. When temperatures surpass 86℉, the plant's leaves might lighten in hue, their tips could dry and shrivel, and the plant becomes more prone to sun damage.
Solutions
Remove the sun-damaged and desiccated sections. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
