Which nut tree?
I want to plant a couple of nut trees in my yard. The site I am buying from says to plant 2 to ensure pollination but one of them may self polinate. I am deciding between a pecan tree and a carpathian english walnut. Being both can become very large trees, should either of these be avoided within 10 feet of buildings, concrete driveways or sidewalks? Both trees are zone 9 trees, so I am okay there. Any experience with either tree and any care suggestions or planting recommendations are appreciated. Oh, one will be planted at the back of my property and one will be closer to my home but 10-12 feet away. Thanks.
