How to add water?

Does the pot have a drain hole at the bottom? If yes, then set the pot in a saucer and add water to the saucer. If no, then carefully add water to the soil near the edge of the pot.

Actually, if the pot does not have a drain hole, you should repot the succulents in a new pot that does have a drain hole.

By the way, I water my house plants only once each week. With a proper potting mix, that is sufficient.

Thanks a lot.

Actually, there are two pots as shown in the second photograph. The red one put inside the white one.

No hole at the bottom of the white pot, but there are 15 holes at the bottom of the red pot.

You could put water in the white pot to wick through holes in red but since it is so big if you are not carefully flooding may harm the plant. Usually pots like the red pot have a saucer beneath them to hold excess water.
