As irrigation restrictions take effect in more cities, gardeners are struggling to keep their plants alive through blistering heatwaves. But reaching for the hose is only part of the solution.
According to British gardening expert Monty Don, the real secret lies in how well your soil retains moisture. The prolific author and longtime host of BBC’s Gardeners’ World recently told Country Living that healthy earth is the ultimate key to surviving summer droughts.
The Sponge Effect of Healthy Soil
Speaking on the BBC Gardeners’ World Magazine podcast, Don explained that plants should not constantly rely on external watering. The permanent fix is cultivating soil rich in organic matter.
This creates a loose, humus-rich earth that acts like a natural sponge. It holds moisture far longer, allowing root systems to sustain themselves even when the surface feels bone dry.
Instead of obsessively watering, Don advises gardeners to focus on long-term soil improvement. Hot weather exposes exactly how critical a healthy underground environment is for a resilient garden.
Timing Your Watering Sessions
While soil quality dictates water retention, proper watering technique remains essential. Don emphasizes that early morning is the optimal time to hydrate potted and container plants.
Morning temperatures are cooler, minimizing immediate evaporation. If a morning soak is impossible, wait until the evening.
Watering in the middle of the day is highly discouraged. The intense sun and peak heat will simply bake the moisture away before the roots can absorb it.
Water Deeply, Not Constantly
A frequent mistake gardeners make is giving plants a shallow sprinkle every day. Don argues that a thorough, deep watering is a far more effective strategy.
Pushing moisture deep into the ground forces roots to stretch further down. This natural adaptation offers two massive benefits:
- Roots grow deeper into cooler, moister soil layers.
- Plants become inherently more resistant to prolonged droughts.
For a thriving summer garden, prioritize organic compost over the watering can. A healthy, humus-rich soil is the only way to ensure plants store water longer and easily outlast dry spells.
