Use this method of watering when you are sowing seeds: use a shallow tray or trough larger than the seed tray or pot. Fill it with water until it is approximately 3cm deep. Stand the seed tray in the larger tray until the compost darkens in colour and is wet to the touch. Do not stand plants or seeds in water for more than 4 hours.
Watering can with rose
This method of watering is used to water seedlings once they have germinated, either in pots or the soil. Using a rose means that water flow is gentle and will not wash the seedlings and compost away.
Watering can without rose
This is probably the most widely used watering method in gardening. It is an easy way to control water flow and is used to water established plants in pots and containers (including hanging baskets). Many gardeners water a seed drill with a can before sowing.
Hose with lance or spray gun
This provides a rain-like effect for watering with a heavier flow than a watering can. More water can be delivered in a shorter time. Using a lance will give extra length to reach hanging baskets or the back of a border.
Hose without a lance or spray gun
Commonly used to fill ponds quickly and water mature plants in containers or those planted in the soil. Kink the hose near the watering end to provide more control over water flow. This method is best used by adults or older children.
Trickle or drip irrigation
Separate pipes originate from a single hose pipe, providing individual pots or plants with water over a period of time. This method is especially useful when growing crops of all one type and size. These pipes are usually set up in their permanent position and can be controlled automatically using a tap and timer.
This can be either a flat pipe with holes either side or porous pipe, which allows water to seep into the soil over a period of time. These pipes are usually set up in their permanent position and can be controlled automatically using a tap and timer.
Unlikely to be used in a school garden, however sprinklers may be used when watering a newly planted area or at times of prolonged drought.
