Beat the hosepipe ban: 7 ways to use less water in your Kent or Sussex garden

Kent and Sussex sit in the driest corner of England. Southern Water and South East Water serve one of the most water-stressed regions in Europe — and hosepipe bans have become a near-annual August event. The good news is that most garden water use is wasteful and easily reduced.

Here are seven changes that make a real difference in our region's conditions.

1. Install a water butt — A single 200-litre water butt can collect enough rainwater from a small roof to water a vegetable garden through a dry spell. Kent and Sussex receive most of their rainfall between October and March — so fill your butts over winter and use them strategically through summer.

2. Let your lawn go dormant — Grass goes brown in drought but it doesn't die. It will green up again with the first autumn rains. Watering a lawn during a hosepipe ban is both wasteful and illegal under Southern Water and South East Water restrictions. Replace lawn with a gravel garden or drought-tolerant ground cover to reduce the temptation.

3. Water in the evening — Watering in the evening reduces evaporation by up to 70% compared to midday watering. In the long, warm south-east evenings of July and August, this is especially important. Morning watering is better for anything prone to fungal disease — a consideration on the humid, sheltered soils of the Weald.

4. Water the roots, not the leaves — A slow trickle at the base of a plant is far more effective than a spray over the foliage. A leaky hose or drip system delivers water exactly where it's needed — and is permitted even during most hosepipe ban restrictions, which target hand-held hoses rather than fixed irrigation.

5. Mulch everything — A 7cm layer of mulch reduces soil moisture evaporation by up to 75%. On the free-draining chalk soils of the South Downs and North Downs, this is transformative. Apply in spring when the soil is moist, and top up in early summer before the dry season begins.

6. Improve your soil — Soil rich in organic matter holds water like a sponge. This is particularly valuable on the sandy soils of coastal Sussex and the thin chalk soils of the Downs, which drain rapidly. Adding compost annually increases water retention significantly.

7. Group plants by water needs — Keep thirsty plants like dahlias and vegetables together near a water source, and drought-tolerant Mediterranean plants in the driest, sunniest spots. This makes watering more efficient and reduces waste.
