Saving water in the garden is just as important as in the home. Mulching, collecting rainwater and planting drought-resistant plants can help shrink your sprinkling.It’s important to save water in the garden for two reasons. First, to save money if you’re on a water meter – 40% of us, and rising, are. Second, because at peak demand up to 70% of our water supply can be used in gardens, which forces suppliers to use groundwater and take it from streams. This can cause environmental damage and increase water prices. Here are five ways to minimize your use of water in the garden.
Update your irrigation system with a smart controller. A slightly larger investment ($300 to several thousand dollars) will buy you a weather-based irrigation controller capable of improving your watering efficiency by up to 40%. If your water bill has been large it will probably pay itself back within a couple of years.
Eliminate leaks. According to the EPA, a single 1/32” diameter leak on a hose, emitter or outdoor faucet can waste more than 6,000 gallons of water in a year. Imagine the cost if you have multiple leaks! Outdoor leaks are especially prone to waste because they often aren’t noticed. If you hire a competent landscape company to maintain your lawn, you won’t have to worry because they will check for leaks at each visit. However, if you do your own maintenance, be sure to put leak inspection on your weekly list.
Water at the right time.Many of us over-water our gardens. This is not only wasteful, it means we’re doing more work than we need to. To check if you need to water or not, look at the soil about a spade-deep down. If it’s damp, it’s fine; if it’s dry, it’s time to water. If you have clay soil, it might feel damp whether it’s irrigated or not and sandy soil can feel dry, even if it has water in it. If this is the case, watch your plants and when they start to show signs of water stress – when leaves change position or get darker – note how the soil looks and feels. This way you can get more of an idea of what your soil is like when it has too little water.
Watering the garden before a drought sets in keeps the soil’s moisture levels up and helps prevent a water deficit. You should also water plants in the evening when it’s cooler, to reduce evaporation.
Use the right amount of water.This depends on the soil type. Light sandy soils need watering more often than heavy soils. Clay-based soils can be watered less frequently, but need more water. The Royal Horticultural Society’s rule of thumb is that for plants to keep growing, up to 24 litres per sq metre (5.2 gallons per 10 sq ft) every seven to 10 days is sufficient. That’s about two and a half 10 litre watering cans worth per sq metre.
Water the soil, not the leaves. Water at the root zone to keep evaporation to a minimum. Keeping water off your plants’ leaves will also help control fungal diseases and prevent sunscald. A professionally-designed irrigation system – drip or otherwise – is far better at proper water delivery than the simple lawn sprinklers you can buy in the hardware store. It is an investment that will pay for itself over time in reduced water bills and healthier plants.
