How to protect garden plants in hot weather

The high temperature in summer can be a difficult time for garden plants. Especially in the case of low rainfall, continuous exposure to high temperature will cause dehydration and sunburn of plants such as trees, shrubs, lawns and flowers, and also reduce the ability of plant roots to absorb fertilizer. Many home gardeners want to know how to protect garden plants in hot weather. If you are looking for solutions or tips, this guide on how to protect garden plants in hot weather will help you.

Apply mulch

Applying mulch to garden plants is one of the simplest ways to keep the soil moist. You can cover at least 4-6 inches of organic covering around the garden plants. The mulch will protect the soil from direct sunlight, keep the soil moist and slow the rate of water evaporation, thereby reducing the need for watering. Most mulches can also be used as natural substitutes for fertilizers for garden plants.

Gardeners can use many cheap covering materials. Air-dried grass clippings, straw, compost, nutshell, pine needles, weathered wood shavings, various bark shavings, and even stone materials will help garden plants maintain cooler top soil conditions in high-temperature weather, while also suppressing weed growth .

Make sure that the covering is deep enough to protect your garden plants during the hot summer.

The high temperature in summer can quickly dry the surface soil, resulting in the dehydration of the shallow roots of plants. In hot weather, water will also be lost through the leaves. At this time, your garden plants need to be thoroughly watered. The best time to water in hot weather is early morning and evening. Water the plants before the sun rises or at night to allow the water enough time to soak into the soil before the sun’s heat rises and accelerates evaporation.

Avoid excessive watering of plants, which can lead to bacterial growth. In addition, make sure that water does not stay on the leaves during the day, because when the water evaporates at high temperatures, it can cause burns.

In hot weather, scientific and reasonable watering will protect your garden plants.

Provide shade

In addition to proper watering and application of mulch, hot weather also needs to provide shade to garden plants. Big trees and buildings provide natural shaded areas for the garden. In addition, you can use parasols, old curtains and sheets, or go to the garden center to buy shade cloth to cover the rest of the garden during the day. When using old curtains, sheets, and shade cloths, you need to pay attention to the shading factor, ventilation, and fixation.

The shading factor refers to the degree of sunlight blocking. In hot weather, your garden plants may require 50% to 90% shade.

When using shade cloth, old curtains or bed sheets, please maintain good ventilation. There is no need to completely surround garden plants.

Fix these shading materials to fences, walls or wooden stakes nearby. If there is no fixable thing near the plant, you can consider setting up a temporary frame, hanging the shading cloth, old sheets or curtains on the frame.

Hot weather is the easiest and most practical way to provide shade to garden plants.

Plant heat-resistant plants

If you live in a hot climate. Please plant heat-resistant plants to keep the garden healthy. Such as sunflowers, rosemary, magnolia, lavender and other plants. When adding new plants to the garden in summer, plant them on a cloudy day and avoid direct sunlight.

Keep the height of the lawn

When cutting lawns in hot weather, you need to control the cutting height. Usually the lawn only needs to be cut into 2.5 inches, adjust the lawn mower blade to a higher position in hot weather, keep the lawn 3-6 inches long, and the longer grass provides the maximum shadow for your soil, which will help the soil Stay hydrated.

Check the blades of the lawn mower to ensure that the grass is cleanly cut. Plants heal faster than when cutting grass with blunt blades.


High temperature weather should avoid fertilizing plants. Although applying organic fertilizer in hot weather will not damage your garden plants, hot weather will reduce the ability of plant roots to absorb nutrients. Fertilize the garden plants until the weather become cool.
