Surviving the Heatwave with Hortiwool
There's nothing quite like a proper British heatwave to remind us how unprepared our gardens (and we) can be for sustained heat. One minute we're complaining about grey skies, the next we're hunting for shade and wondering why the hanging baskets look like they're auditioning for a drought documentary.
If your garden is currently wilting under the sun, here's how you can help it!
Deep Drinks, Not Quick Sips
The biggest mistake gardeners make in hot weather is watering little and often. It feels productive, but a light sprinkle barely reaches the roots and encourages plants to grow shallow root systems that struggle even more when it's dry. Instead, water deeply but less frequently, aiming to soak the soil properly so moisture reaches down to where the roots actually are.
Timing matters too. Water early in the morning or in the evening once the sun has dropped, rather than in the middle of the day. Watering in full sun wastes a huge amount to evaporation, and wet leaves under strong sunlight can scorch. Always aim at the base of the plant rather than over the foliage - it's better for the plant and far more efficient with your water.
Pots and containers dry out fastest of all, sometimes needing water once or even twice a day in a proper heatwave. A simple test: push a finger into the compost, and if the top couple of centimetres feels dry, it's time to water.
Hortiwool to the Rescue
This is where a bit of help from Hortiwool goes a long way. Lining the base of pots and containers with our Hortiwool Garden Pads, or using the wool as a mulch into the surrounding soil, helps regulate temperature and slow down moisture loss. Wool naturally holds onto water and releases it gradually, so instead of compost drying out within hours of watering, it stays usefully damp for longer. That means less time spent with a watering can in hand, and plants that are under noticeably less stress during dry spells.
It also helps insulate roots from extreme heat. Plant roots don't appreciate scorching containers any more than we'd enjoy standing on hot pavement in bare feet - wool around the base buffers some of that temperature swing.
Hanging On in There
Hanging baskets are notoriously thirsty, with all that surface area exposed to sun and wind. Our wool hanging basket liners are designed specifically to tackle this, holding moisture against the compost rather than letting it drain straight through and evaporate. The result is baskets that don't need rescuing every few hours and flowers that keep their colour instead of crisping at the edges.
It's Not Just the Plants That Need a Drink During a Heatwave
It's easy to get so focused on rescuing wilting petunias that you forget your own watering needs. Gardening in a heatwave is genuinely hard work, and heat puts real strain on the body. Keep a water bottle with you while you're out there, take regular breaks in the shade, wear a hat, and try to do the bulk of your gardening in the cooler parts of the day - much like your plants would prefer.
A heatwave doesn't have to mean a stressed garden or a stressed gardener. With the right watering habits and a little help from Hortiwool doing what it does best, you can make it through to the other side, hopefully with a decent harvest of soft fruit to show for it.
