The main thing is to be attentive to the foliage of the tree and the humidity of the earth, you must water your bonsai with rainwater when the earth is slightly dry, if the earth is somewhat humid you must wait a while since the roots are very sensitive to the puddling and can rot due to lack of oxygenation.

To care for succulents you must bear in mind that they need little water, poor soil with good drainage and lots of natural light without direct sunlight. These plants can retain a lot of water inside so you must watch the watering and avoid the strong sun as much as possible.

Tillandsias do not need a lot of water to survive, but they do require a bit of moisture. Irrigation can be done using rainwater or mineral water (as the last option, tap water). This plant likes to be sprayed daily, especially in summer.

Bromeliads should always be humid for this reason, it is best to water the plant once a week, you should increase the amount of water application in the hottest months of the year.

Cactus require good watering that moistens the entire volume of the soil, not only superficially but without reaching the roots well. It is important that the soil dries well between each watering (the hotter it is, the more often the watering should be).
