We have a similar issue with trees adjacent the veg plot.

There is a row of mature silver birch trees next to (North of) the veg
plot.
I've hit shallow tree roots while rotovating the plot within 15 or so feet
of the trees.
Most of these roots (up to 1" diameter) I removed last year and the trees
don't seem to be suffering.

How big is the tree? The usual rule is not to dig under the crown.

If you want to lay cables or a water main in my area the tree preservation
officer insists you write a method statement that says you will hand dig the
trench (or using a "mole") and not cut any roots bigger than 1" in diameter.
