Hello, I got a goat Willow this month and it's not doing great. I planted it in the garden where there is sun most of the day. After that all the leaves have turned yellow and crunchy. The soil was always moist when I checked it with my finger. Today I checked the soil drainage with a hole test and it drained 1.7 cm per minute. I really don't know what is wrong. Is it underwatering ? Overwatering ? Something else? Any help would be much appreciated!!
