Watering Tomatoes

Roots need moisture and air to grow successfully – too much water in the soil on a regular basis will reduce growth and encourage diseases.

 A good root structure is achieved with a balance of both moisture and air.

Try to keep soil just moist is the usual advice. 

Another method is to give the soul a good watering, then let it almost dry-out before watering again.

It's important that there is some moisture in the soil at all times because roots cannot absorb nutrients if the soil is bone dry.

Tomato plants need different amount of water depending on the temperature, whether or not they are fruiting and how many leaves a plant has - the more leaves the more water that's required.
