I planted both of these grey pine trees from one gallon pots 3 years ago. They were the same size back then. Now one of them is four times the size of the other one. They are spaced maybe 100 yards apart, but it's obvious that one of them has deeper soil and more access to water than the other one. Still, the good news is that both of them are still alive.
Rainy winter! Rainy winter! Rainy winter!
