No. As long as your native soil drains well enough so there is no standing water, your pots are better off directly on the soil. Al

Thanks.

Standing water periods (now is one) are infrequent, usually last for one day,
sometimes two.

Tipping them will. Note the difference in water retention between a level pot A and a tipped pot B. If you have a hole on the bottom at the side, make sure it's the lowest part of the pot and slip a brick or 2x4 under the opposite side.

Good idea, to apply the technique to this situation.
