I asked Ai what is the most asked question is when it comes to houseplants and the result was watering schedules. It's actually not an easy question to answer because plants depending on their needs and origin have different watering schedules. Most plants require weekly watering in growing season, but I would not water our succulents or cacti weekly as it would kill them after a short while as they need very little water to survive with them originating from areas of drought. There are also thirsty plants that require watering every two to three days. I made a planter up of three of our plants that like watering every two to three days so that I didn't have to remember to water them separately and they have thrived together, which pleases me.
So how to I determine the watering schedules for our plants? I'm not even sure how I do it, I kind of go by both my intuition and by researching the shit out of the plant that I have purchased or grown. I wouldn't trust the card that comes with information on it with your plant as these tend to be generic and not suited to the actual plant in question. To be honest there are so many different offers of advice out there on the internet and they all tend to differ, so I would say do your research picking a website that seems to offer solid advice I really like either the RHS or the Spruce as they seem to get it right when it comes to plant care. Then I carefully monitor our plants, after keeping plants for a while you will learn to know when they look in desperate need of watering.
The amount of water that you use is also a big thing, I have seen people water their plants in vast amounts, if you do this you will probably have to water less often. I tend to give only a little amount of water to each plant or increase the quantity based on its size.
Some plants like the Hoya you can test if it needs watering by doing the taco test, the taco test is where you take a leaf and fold it, if it folds super easily it needs watering if it is stiffer, it doesn't need watering. Other plants like the nerve plant or peace lily will droop when it's thirsty, you shouldn't really let it get to the droopy stage, but if you do don't worry because plants are often extremely resilient.
