Question
Someone told me that you can't ring a tree with landscape blocks and fill it with soil for flowers because it will kill the tree.
 My question is, can I ring the tree with landscape blocks and fill with soil?

Answer
Hello,

You should absolutely not place soil over tree roots. This will smother the roots. Up to 4 inches of organic mulch can be placed over the roots because material like wood chip mulch is much lighter and has better pore space (air and water gets through) but soil is much too dense and heavy.

Flowers can sometimes be grown in the soil around the tree roots but only in the existing soil under the tree. Good luck. Let me know if I can be of further help.
