When it comes to watering plants, there are a few things you should know. First of all, there are many materials that plants can grow in. Most common is soil. For those plants that grow on soil, you'll want to water them once a week depending on what type of soil you use and how big the plant is.
There are other options out there that may or may not require watering as frequently. Tea and coffee grounds are two examples of growing mediums you could use for your plants instead of soil but we do not recommend it.
Watering plants is a satisfying task, but sometimes it can be confusing. A good rule of thumb is to keep the water temperature about the same as the room temperature. If it's fairly warm in the house, make sure the water is also slightly warmer. This will take the chill off your plants and give them a drink that is more satisfying for their thirsty roots.
However, if water is too hot then it can damage roots or stem of a plant. Therefore, when watering plants always make sure that the temperature of the water is between 60 to 70 degrees Fahrenheit depending on where you live and what time of year it is.
