With brand new pots you can give the inside a coat of PVA glue or acrylic varnish to reduce water absorption but, as with any pot, ceramic, plastic, wood or terracotta, you do actually have to water regularly. Leave an inch or two free at tht otp so you can pour on one good soak a week rather than daily dribbles. Much better for the plants and less work for you. Increase frequency in hot weather and reduce in cold weather.
Adding a mulch of gravel, grit, chipped bark or expanded clay pellets helps reduce water loos by evaporation.
