compost around trees
 

I bought a yard of compost for top dressing flower beds, and also want to
put a couple inches around several two or three year old trees.

My question is: Should I remove the grass before putting on the compost,
or cover the grass and let it grow through?

Next question: How close to the tree trunk should the compost go, and
how far out? ( I thought as far out as the drip line)

Thanks for your advice.
