Watering is a biggie
Choosing the right plant for the right place is central to whether a plant lives or dies, limps along or thrives. Things to consider before you buy are light, time commitment and placement...but the biggie is Water. Plants don’t operate on a “it’s Saturday, therefore I get watered” regime. Before watering, check the moisture levels by using your finger to get down deep in the soil or even better, use a moisture meter. Don’t water if the soil is moist — overwatering kills plants 9 times out of 10, especially in the cooler months. Ensure your plant is never left standing in a pool of water as this can result in root rot. Ensure your pot has adequate drainage and the soil is the right type for the plant ( ie: a succulent mix for your dry tolerant plant friends).
There are lots of moisture meters on the market, some you keep in your plant, and others where you push the probe into the plant to test the moisture level before watering. This assumes you know how to care for that plant — some plants like to be bone dry before watering, such as a ZZ or Sansevieria (aka mother-in-law’s or snake plant, others like to be kept a little moist. There is no one-size fits all with plants so its important to know what your plants is, and what it likes.
