Collect as much rain water as you can
Water use in the garden
Introduction
The aim in an organic garden is to minimise the need for additional watering; also to collect as much rainwater as possible for use in the garden. Where watering is necessary, water should be applied in ways that make best use of it.
Water is often used in a wasteful way in a garden, wasting valuable resources if drinking quality water is used. Over watering can result in leaching nutrients out of the soil and cause soil erosion.

Guidelines
Best organic practice - the first choice
Gardens as 'soakaways'
Gardens act as valuable 'soakaways' for rainwater - an increasingly important function with the increase in heavy downpours. Do not pave or tarmac a whole garden. Even areas used for parking can incorporate some soakaway areas.
- The Organic Way article Gardening with water in mind (PDF 713Kb) contains lots of useful advice and information
- Grow drought tolerant plants where soil is light and free draining

Mulch the soil to reduce water loss
See also:
- Keep soil cultivations to a minimum
- Don't cut lawn grass shorter than 2.5cm; leave it slightly longer in drought conditions
- Allow weeds such as clover and yarrow to grow in a lawn; they will help to keep it green in dry weather
- Ensure pond liners don't leak, reducing the need for topping up
- Try to sow or transplant just before rain is forecast, rather than just before a spell of dry weather
- Protect young plants from sun and drying winds
- Collect as much rain water as you can
- Think before you water; established plants rarely need watering
Acceptable organic practice
- Make efficient use of water by only watering at key points in a plant's lifecycle, and then only if necessary
See also:
- Give plants a good soaking so that the water penetrates the soil
- Apply water to the soil rather than foliage. A hand held hose or watering can will direct the water where it is needed
- If using an irrigation system, chose a drip system rather than sprinklers
- Water in the evening or at night rather than in the heat of the day to minimise losses through evaporation
Acceptable, but not for regular use
- Use 'grey' water, from baths, sinks and showers, to water non-food plants
