Hoses and watering cans
Time consuming and labour intensive, watering by hoses or watering cans should be aimed specifically at the base of the trees, shrubs and hedges, beneath the foliage leaving the surrounding soil dry which limits weed growth and ensures that all the water gets to where it is required.
This is by far the best way to water hedges, especially when it is controlled by an automatic timer making it both economical and efficient. Trees and shrubs can also benefit by having circles of the dripper pipe laid at their bases. Watering amounts and times can be easily adjusted as required.
Covering wide areas, sprinklers are Ideal for lawns and recently seeded areas but we do not recommended them for watering trees, shrubs or hedges, as the water is not directed, directly to where it is most required.
How much water to apply
This is not an easy question to answer as soil types, weather conditions and locations have effects on how much water a plant will require. Every horticultural professional will have their own recommendations for example; The Royal Horticultural Society suggest as a general guide that up to 24 litres per square metre (5.2 gallons per 10 square foot) every seven to ten days will be sufficient to maintain plant growth.
In our opinion, by following our guidelines and above all, the regular monitoring of the appearance of the plants together with the moisture content of the soil around them is the most accurate indication of when and how much water to administer.
