Reply to comment by FaceDeer in Planting more trees could axe summer deaths by a third. Modelling of 93 European cities finds that increasing tree cover up to 30% can help lower the temperature of urban environments by an average of 0.4°C and prevent one in three heat deaths as a result. by MistWeaver80

One ironic addition to this is another common issue is people often don't dig a big enough hole. They dig a small hole and put the tree as deep in it as they can. In truth, you want a big hole that can allow the roots to spread out the same way they naturally grow, but still have the boundary of the root/tree at the surface of the ground.

My parents, who have planted enough trees on their 40 acres, that it has affected their microclimate significantly, say if you buy a $10 sapling, dig a $100 hole. It needs to be both deep and wide. And if you have hardpan, you need to break through it.
