Answer: Tanyosho Pines are tolerant of moist to dry soils and full sunshine to part shade. Since your tree has only been in the ground for a few months, it is important to water it deeply and regularly until the roots have a chance to establish themselves. It doesn't sound as though you've been watering on a regular basis, which could account for the yellowing needles. Insects can also cause yellowing so inspect the needles closely for tiny spider mites or other insects. Be sure to water your tree deeply (one-inch per week) throughout the spring, summer and fall months until the roots are well established. Best wishes with your pine!
