Hi,
Sorry i am new to this forum! I have recently bought a three foot high silver birch...id like some advice - i was told that i would need to plant the tree as far away from the house as its adult height, so for birches it would need to be about 30ft. IS this correct? can it be planted closer to the house without ruining the house foundations ect? At the moment i have it planted in a pot & i was told that this is okay & i can keep it as a bonsai..is this true? if so does anyone have any tips?

Many thanks!
