Hi everyone I'm wanting to plant a few birch trees at the bottom of my garden to create a bit of privacy and hide the mill. I have chosen the birch trees as I like their light canopy and slim trunk. The trees would be about 1.5m away from the fence. I was thinking of planting four birch trees, about a metre apart starting from the right hand side of the garden. And in the bottom left hand corner, I was looking to plant an apple tree that grows up to about 2-3m. I have a few questions I would appreciate help with. 1. Can I plant birch trees 1m apart? I would like to keep the tree heights to about 10-15m so thought keeping them closer together might help keep them at a shorter height. 2. How fast do birch trees grow? 3. Are they good on clay soil? 4. As I am in Manchester, we are prone to a lot of rain. Will a lot of rain affect the Birch trees? 5. Which type of birch tree would be best as I would like something that reaches a height of about 10-15m. 6. I read on another forum something about their seeds self planting. Is this something I should be concerned about? 7. When do the trees need to be planted by? I have seen trees for sale at reasonable prices that are about 6-8ft. 8. Do I need to worry about the roots be invasive and causing damage to surrounding properties?
