The No. 1 mistake people make when growing houseplants is that they kill them with kindness by over-watering.
How much water does a plant really need, and how can you tell? Here are some tips for ensuring that your plants get the right amount.

The rule of thumb is to water your plants once a week, but in fact, plants have different variables:

  • The smaller the plant, the quicker it will dry out.

  • The containers you use also make a difference. Plastic containers hold water, while clay pulls water away from the soil.

  • Where you place the plant also matters. Plants that are in direct sunlight need more watering than those that are not.

  • Watch the plant. If the leaves are drooping, the plant needs water.

  • Also keep an eye on the soil. There are moisture meters available at garden centers. Just place the metal probe into the soil and it will indicate a water level from one to four. A list of plants comes with the instructions, which tells you the correct water number for each plant. Or, checking the soil moisture can be as simple as using your finger. Insert your finger in about one inch of soil. If it feels wet, you don't need to water it.

    And keep in mind, plants don't like wet feet, so let excess water drain out.
