Beating the Heat

How to Keep Your Garden Thriving During a Summer Scorch

Looking After Your Garden During a Hot Spell

We all love it when the sun finally decides to shine, but a sudden heatwave or a prolonged dry spell can leave our gardens looking a little tired, thirsty, and sad. When the temperatures rise, our plants need a bit of extra TLC to keep them looking their best. Here at Beautiful Gardens, we’ve put together our top tips for helping your outdoor space survive, and even thrive, when the weather turns hot.

Water Smart, Not Hard

When the sun is beating down, it’s tempting to grab the hosepipe in the middle of the afternoon. However, watering during the hottest part of the day is highly inefficient. The water evaporates before it reaches the roots, and droplets on leaves can act like tiny magnifying glasses, scorching the foliage. Instead, aim to water your garden either early in the morning or late in the evening. Focus the water directly at the base of the plants, right at the soil level, rather than over the leaves. A really good, deep soak every few days is actually much better for your plants than a light sprinkle every single day, as it encourages the roots to grow deeper into the soil to find moisture.

The Magic of Mulch

If you haven’t already, applying a layer of mulch is one of the best favours you can do for your garden in the heat. A thick layer (about 2 to 3 inches) of organic matter like bark chippings, well-rotted manure, or garden compost spread over your borders acts like a protective blanket. It shades the soil, dramatically slows down moisture evaporation, and helps to keep the plant roots cool. Just be sure to apply it when the soil is already damp.

Relax on the Mowing

It might be tempting to give the lawn a short, neat crop ready for a weekend barbecue, but during hot, dry weather, it is best to raise the blades on your mower. Leaving the grass a little longer (around 2 to 3 inches) helps the individual blades cast shade over the soil, which prevents the grass roots from drying out and turning yellow. If your lawn does go brown, don’t panic, grass is incredibly resilient and will quickly bounce back to a lush green as soon as the rains return.

Care for Your Containers

Potted plants and hanging baskets are always the first to suffer in a heatwave because their roots cannot dig deeper to find water. They may need watering twice a day during extreme heat. If you can, temporarily move your pots into a shaded spot to give them a break from the midday sun.

With a little bit of strategic watering and a gentle touch, your garden can weather the heat perfectly. Stay cool, stay hydrated, and enjoy your beautiful summer garden.
