IT looks like the hot weather is going nowhere.

And while we might be loving it, our aren’t as big of a fan.

Especially as our and grass aren’t just tackling the heat, they’re also struggling with a lack of rainfall, and hosepipe bans are put in place.

Fortunately, there are plenty of plants that can withstand the harsh conditions.

And you can get them for as little as £2.99 so you won’t have to spend a fortune replacing any dead ones.

B&Q’s Outdoor Expert, Mark Sage says:“When the temperature rises, choose plants that not only survive in the heat, but thrive in it – think ‘right plant, right place’.

“Mediterranean favourites like lavender, catmint, and Echinacea are great to include in your garden, along with rosemary, which is always a welcome addition to the kitchen too. These plants are perfect for sunny spots, having evolved with adaptions such as deep roots, hairy foliage, water conserving oils in their leaves, or succulent textures that conserve moisture.

“In the first year, the plants will need regular, deep watering to help them establish themselves in the garden, but once settled they flourish on minimal watering. To boost resilience, try adding organic mulch or homemade compost before hot spells to retain soil moisture and suppress any weeds.

“With the right soil, sun, and a layer of mulch, these plants will bring vibrant, low-maintenance beauty to your garden all summer long.”;
