How much water does my fern [1] need? Does it need more than my jade plant? It can be very frustrating when the care label on the plants suggests "evenly moist." So how do you know when and how often to water your plants?

All houseplants are governed by their surroundings. The container, type of soil, temperature and humidity levels in the house, along with the amount of sun outside all play a large role in how much water your plant needs. The first thing to look for when trying to gauge your watering frequency is that your potted plants are growing in containers with drainage holes.

Next, rather than letting the calendar tell you when to water, learn to feel the soil. When the soil feels dry to the touch, just below the surface, it's time to water. Another way to determine your plants need for water is to lift the potted plant [2]. Do this right after watering, then again in a few days. Note how much lighter the plant feels. This method uses the weight of lost water as an indicator of when you need to add more. With experience you will learn how light you can let each plant get before it wilts. Be sensitive to each plant's habits so that you never allow them to wilt.

When watering, use only room temperature water and avoid softened water, which has added salts that can build up in the soil. Water thoroughly so that the water drips out the drainage holes. This helps flush excess salts and toxins from the soil, as well as indicating that the soil is completely wet. One precaution - never allow the excess water to stand in the plant saucer for longer than 30 minutes.

A little time spent learning how each plant responds to its environment will make watering an enjoyable chore.
