Is it necessary for outdoor plant? Just let the excess water drop onto ground.

I find it is needed during our hot summer. Probably not in the winter.

Pot plants can't go deeper to look for moisture, the same way plants in the ground can.

What you are saying does not make sense, the hole should have another purpose --- "let the air go through". If the level of saucer water is above the hole, then the air cannot come through the hole.

My initial thought was: the purpose of saucer is holding excess water and not letting water drop on flooring, it seems to me it is only for indoor use.

The saucer has one of two purposes. 1) to protect the area under the pot safe from drips, and 2) to hold extra water that keeps the soil water-saturated in the pot. So, for an outdoor pot where you water from the top you do not need or want a saucer, unless the plant is very water loving and needs to be in moist soil all the time. If the last is true you would like a small amount of the water in the saucer most of the time.

I don't know what you don't understand.

Air isn't going through the hole. Moisture is.

Outdoors, terra cotta pots can hold moisture that the potting soil slowly absorbs. It helps keep plants continually moist instead of cycling from dry to soaked. Terra cotta can also hold nutrients that might otherwise be washed away with the sudden gush when you water the plants.

Saucers are used under outdoor pots two reasons: 1) To keep the water from dripping onto the decking below the pot, which stains the decking and over time causes the decking to rot, which, in my case, causes my husband to become unhappy and complain-y. 2) To hold extra water for the plant to soak up over the next day or two during hot weather, which causes plants to become happy.

You don't need air to go up through the hole.

I don't use them as the standing water attracts mosquitos. However I don't have the conditions oldgardener mentions.

This ^^^^ I empty mine as soon as I see water but it keeps the deck cleaner.

Here we use saucers to keep the roots from crawling out.
