Watering your garden in summer: smart tips to save water

Water: the difference between surviving and thriving

Last summer is still fresh in my mind. Weeks without a drop of rain, cracked clay soil, plants drooping as if they'd given up. My neighbour's garden, though? Absolutely flourishing. Her secret? She watered less often, but she did it cleverly.

GardenWorld helps you visualise your garden's potential after seasonal care. Handy for working out where your plants sit and planning your watering routine.

When should you water?

Early morning is by far the best time. The water soaks into the soil before the sun can evaporate it. The plants have the whole day to absorb it. Watering in full sun is pouring money down the drain: up to seventy per cent evaporates before reaching the roots.

Evening watering works too, but has a downside: the foliage stays damp all night, which attracts fungal disease. If you do water in the evening, aim the stream at the soil, not the leaves.

How often?

Less frequently, but thoroughly. That's the golden rule. A daily light sprinkle produces shallow roots that give up at the first heatwave. Water deeply twice a week instead, getting the soil wet to about twenty centimetres deep. Your plants will develop deep roots that seek out moisture on their own.

The right techniques

A watering can is still the most efficient tool for small gardens and borders. You deliver water exactly where it's needed, with zero waste. For larger gardens, a soaker hose is brilliant. Lay it along your plants and water seeps slowly into the ground. Garden centres stock complete kits for a reasonable price.

Sprinkler systems that drench the whole lawn look jolly, but waste enormous amounts of water. Reserve them for the lawn and preferably set them on a timer for early morning.

Harvesting rainwater

A water butt is the simplest way to collect free water. Connect it to your downpipe and a single heavy shower provides hundreds of litres. Rainwater is actually better for your plants than tap water: it contains no lime and is the right temperature.

Mulching: the secret water saver

A five-centimetre layer of mulch on your borders halves evaporation. Compost, bark chips or cocoa shells all work. It keeps the soil cool and moist, suppresses weeds and looks attractive too.

Mulch your borders at the start of summer while the soil is still moist. Mulching dry soil is less effective: you're locking in the drought.

Lawns and drought

Here you face a choice. A lush green lawn in summer demands a lot of water. One option: accept that your grass turns brown in July and August. It recovers the moment rain returns. British grass is perfectly adapted to this.

Want green grass anyway? Mow higher, at least five centimetres. Longer grass shades the soil and retains moisture better. Water once a week, deeply, early in the morning.

Holidays: who waters your garden?

Going on holiday? Ask a neighbour or family member to water every few days. Give clear instructions: which plants are the thirstiest? Container plants are the most vulnerable.

An alternative: put a drip system on a timer. That investment pays for itself in surviving plants. Move pots into the shade and give everything a thorough soak before you leave.

Smart watering pays off

A mindful approach saves water, money and frustration. Your plants become healthier and your garden looks better. It's not about more water, it's about the right water at the right time.
