Always a good idea Caz8 as the drainage holes can get blocked if the tub is on the ground. Trees also have a tendency to send roots down through the drainage holes. If the tub is kept slightly clear of the ground then roots will 'air prune' themselves and not do that.
A trowel in the hand is worth a thousand lost under a bush.
