Watering your garden
Watering is where most beginners go wrong, usually by watering little and often. That keeps roots shallow and weak. The trick is to water deeply but less often, so roots grow down and plants cope far better with dry spells.
The four rules: deeply (soak, do not sprinkle), less often (let roots grow down), in the morning (less evaporation) and at the roots (keep the leaves dry).
How much and how often
Most established plants prefer a good soak two to three times a week to a daily splash. Water until the soil is moist several centimetres down, then let the surface dry before the next round.
Check with a finger: if it is damp below the surface, leave it. Sandy soil and containers dry faster; clay holds water longer.
When
Early morning is best. Plants drink before the heat arrives, and leaves dry quickly, which discourages disease. Evening is second best. Watering in the midday sun is wasted: much of it evaporates before it reaches the roots.
Seedlings and containers
Young seedlings have tiny roots. Water gently from below or with a fine rose, and never let them dry out — but avoid sogginess, which causes damping off.
Pots and containers dry out fast, especially in wind and sun, and may need daily watering in summer.
Using less water
A mulch locks moisture into the soil so you water far less often. Water at the base rather than over the leaves, group thirsty plants together, and collect rainwater in a butt. Soil improved with organic matter also holds water better.
Over- or under-watered?
Sign | What it means |
|---|---|
Wilting, dry crumbly soil, crisp leaf edges | under-watered |
Yellowing leaves, soft growth, constantly soggy soil | over-watered |
When unsure, check the soil below the surface before reaching for the can.
Frequently asked questions
How often should I water? There is no fixed rule — check the soil. A deep soak two to three times a week beats a daily sprinkle for most plants.
Should I water every day in summer? Containers often yes; beds usually no. Water deeply and let the surface dry between.
Is it bad to water in the evening? It is fine; just try to keep the leaves dry to avoid overnight disease.
Can I overwater? Yes. Soggy soil starves roots of air and rots them. Moist, not wet, is the aim.
