A Hot Summer: How to Protect Plants From Heat

Posted on July 15, 2019 by Devon Metcalfe

As we gear up for another (hopefully) hot summer, excitement starts to kick in about the endless BBQ opportunities, days out at the beach and spending time in the garden with friends and family. However, as fun as a hot summer is, there’s always a worry about what effect it will have on your garden. After all, not all plants are suited for such extreme temperatures. If you’re concerned about looking after your plants, read out quick guide on how to protect plants from heat:


When Should You Plant in the Warmer Weather?

You might want to add more plants to your garden once the weather starts to heat up. But there is a time and place for when to do this! Plant on a cloudy day where possible, and water well if the weather is particularly warm. You should also use a half mulch/half potting mix to increase its chances of surviving.

How to Protect Plants From Heat


  1. Don’t Over-Water Plants

Though it seems contradictory, over-watering your plants when it’s hot can do them more harm than good. This is because it can cause them to leach nutrients and cut off the supply of oxygen to the roots. And, when you do water your plants, focus the stream at the base of the plant so the roots can benefit as quickly as possible. A top tip for how to protect plants from heat is that you should water them first thing in the morning or early evening.

  1. Provide Lots of Shade

Many plants can survive the heat if they’re also given a lot of shade. If your garden typically gets a lot of sun, then it’s a good idea to create an area where plants who need shade can get it. This could be anything from simply planting shade loving plants next to a fence or providing your own shelter with special shade cloth.


  1. Feed Your Plants

Give your plants long-lasting moisture and rich nutrients to breathe some life back into them during a hot summer. Lay down a thick layer of mulch onto the top few inches of the soil as this will keep the roots moist and cool which is a key factor in how to protect plants from heat. In turn, it will help plants grow and reduce the amount of watering required. This can also hinder weeds, which saves you time and money trying to get rid of them!

  1. Plant Drought-Resistant Flowers

When you first start bringing your garden together in the spring, you may wish to consider draught-resistant plants. There are plenty of beautiful plants that will add colour and texture to your garden while at the same time remaining resilient to changes in the weather. Plants such as lavender, rosemary and marjoram all thrive in the heat, with their flavours and scents becoming stronger in the hotter weather.


  1. Mow Your Lawn Less

If you’re someone to likes to keep on top of your lawn growth, then try to restrict it to once a week. Moving your lawn too frequently can cause it to dry out and become crisp and brown. When it begins to rain again, it will soon recover. Moreover, before summer season even begins, prepare your lawn by sprinkling some fertiliser over it.
