I planted a bare root red fuji tree several months ago along w/several other fruit trees. All are thriving except the fuji which has brown dried-up leaves. What should I do?

Brown leaves on an apple tree can be caused by heat stress but it can also show those same symptoms if it is in poorly draining soil and the roots are over saturated. It's difficult for me to diagnose without actually seeing the plant. If the leaves are crispy brown, it's the sunshine - if the leaves are still soft but brown, its probably a water issue. It's important to water deeply and then allow the top of the soil to dry out some. If the ground remains too wet it can drive out the oxygen and the roots can suffocate. Dig down into the soil 3-4 days after watering to see how moist or dry the soil remains. If it is still wet, it isn't draining well enough. If it is dry, it's time to water. You can collect some of the leaves to take to your cooperative extension office or Master Gardener clinic for additional help. Good luck with your Fuji.
