Q.I Have 2 New Trees. I Planted (4′ Tall With Leaves) 2 Weeks Ago. Have Been Watering Thoroughly As Instructed. Several Leaves
have turned yellow on one of the trees. Should I worry about it? Tree has about 30 leaves and about 8 have turned yellow.

Unfortunately, your photos did not come through. I am unable to see the damage. If it has only been 2 weeks and the leaves are turning yellow already, then I would suspect that the tree has been overwatered. The soil must remain slightly moist, but the top needs to dry out down to about 2 inches, very thoroughly. This will ensure that the under soil remains moist, but not saturated. Saturated soils will suffocate fresh plantings.
