The leaves look dry and shriveled. The stems seem to exhibit physical damage caused by some kind of a rasping/grating insect.
However this is my opinion and would suggest that you immediately contact the horticulture department at your place. Take with you a sample of the above, so that they can identify immediately.
Hi? You have not mentioned when they planted. However, it seems saplings planted in July-2017. Reasons for drying are Shortfall of water/ Saplings have not properly planted while planting/ though leaves are falling, but, shortly new buds will come subject to providing sufficient water. Have you taken plants photos before planting? can you pls. come up with all measures taken before and after planting the saplings?.
Hi, These plants where planted exactly one year back (Jul 2016). You is not available in abundant, we are providing water through drip…sending the photos during planting a year back
