I suspect you had some type of wind event that caused so many trees to 'lean'. If the raised bed was added and then the tree was planted, it could be the tree roots didn't go deep into the native soil. If the raised bed was added after the tree was planted then covering the rootflare could...

It also appears that soil was added to make a raised bed. Take a look again at the pics and click to enlarge. I see some type of ring around the tree. Newt

Hi Shank, A root barrier can be installed, probably on your property, unless you can get the land owner to take action. Do you know what type of tree is doing the damage? I would suggest you take pictures of the damage and include pics of the trees causing the problems. I know that in...

Bayou Tree, from what I'm reading the treatment for ball moss with baking soda is used at a rate of something like 40 pounds of baking soda per 100 gallons of water which translates to 2.5 pounds to a gallon, or 60 pounds of baking soda per 100 gallons which translates to 1.66 pounds per gallon...
