One GoodGymer planted 125 Midland hawthorn trees on Petersham Common. It was a beautiful sunny bright winter day and the target to get in 1,000 native tree this winter on Petersham Common is nearly complete. Not everyone was born this way to plant these thorns as they have such large roots so each thorn tree required extra digging. It is the final stretch with another 150 thorns left to plant on Friday 31 Jan.
