Why do plants need water?

• Water keeps plants upright and stops them
  wilting.
• Plants also need water to make food and to carry
  nutrients through them.
• Some plants need lots of water and othere need
  very little.

Watering methods

• Most plants can be watered from a watering can,
  from above.
• Some need to be watered from below, by standing
  the pot in a water filled tray for a few minutes.

Capillary matting

• This is a material that absorbs water and stays
  moist.
• Pot plants placed on a bench lined with moist
  capillary matting will absorb the water.

5
Underwatering and overwatering

• Underwatered plants wilt, have dry, yellow leaves
  and dry compost.
• If compost or soil is waterlogged, roots are
  starved of air.
• Overwatered plants have soft, rotting or mouldy
  leaves and slimy compost.
