On the packet of sodium chlorate it says "do not use near to
flowers,
shrubs etc."

Does anyone have any advice as to how near is near?

Sodium chlorate is absorbed via the roots. Try to imagine how far the
roots will have spread and put no Sodium chlorate closer than that
distance from the main stem + about two feet (because the stuff can
migrate sideways).

In other words, it is fairly dicey stuff to use.
