Mulching with straw can help protect plants from heat and sun exposure while also insulating the soil.

Watering plants early in the day and moving potted plants into shaded areas during the hottest part of the day are also effective strategies.

Finally, building a windbreak can protect plants from drying winds.

Key Points:

  • Use shade cloth with 30% to 50% light blockage to protect plants from the sun.
  • Avoid direct contact between shade cloth and plants to prevent burns.
  • Support shade cloth with stakes or cages a few inches above plants.
  • Secure shade cloth with twine or rocks during windy conditions.
  • Consider using row covers made of lightweight or heavyweight materials for sunlight protection.
  • Build shade structures or trellises for vining plants to offer additional shade.


Did You Know?

1. Did you know that placing a layer of crushed eggshells around the base of plants can help protect them from the sun? The jagged edges of the shells can create shade, reducing the intensity of sunlight and preventing damage to delicate leaves.

2. Some plants have developed natural sunscreen mechanisms to protect themselves from excessive sun exposure. One example is the sunflower, which contains pigments called anthocyanins that act as natural sunblock and shield the plant’s delicate parts from harmful UV rays.

3. In ancient Egypt, people used palm leaves to create natural sunshades for their plants during the scorching hot summer months. The leaves were carefully layered above the plants to provide shade, reducing the risk of sunburn and dehydration.

4. Sheltering plants from the afternoon sun can be done by constructing a simple, temporary shade structure using an old umbrella. This method not only offers partial shade but also allows for easy mobility and adjustment depending on the plant’s sun exposure needs.

5. Placing reflective surfaces, such as aluminum foil or mirrors, strategically around plants can aid in protecting them from excessive sunlight. The reflective surfaces bounce the sunlight back, preventing plants from getting too hot and reducing the risk of sun damage.

Different Grades Of Shade Cloth

When it comes to protecting plants from the sun, shade cloth is a versatile and effective tool. Shade cloth comes in different grades, ranging from 20% to 90% light blockage. The choice of shade cloth depends on the shade tolerance of the plants being protected.

Shade-tolerant plants, such as ferns or hostas, may require higher grades of shade cloth, such as 50% to 90% light blockage. On the other hand, sun-loving plants, like tomatoes or peppers, may only need a shade cloth that blocks 20% to 30% of light.

Recommended Shade Cloth Percentages

According to the Penn State University Extension, most garden plants benefit from using shade cloth with 30% to 50% light blockage. This range provides adequate protection from the sun while still allowing sufficient light for photosynthesis. It is important to find the right balance between shade and light, as excessive shade can inhibit plant growth.

  • Shade cloth with 30% to 50% light blockage is recommended for garden plants to ensure optimal growth.
  • Finding the right balance between shade and light is crucial for plant health and growth.
  • Excessive shade can hinder photosynthesis and inhibit plant growth.

Proper Placement And Support For Shade Cloth

When using shade cloth, it is crucial to avoid direct contact between the cloth and the plants. The heat that builds up when the cloth touches the leaves can burn and damage them. To prevent this, stakes or cages can be used to support the shade cloth and hold it a few inches above the plants. This allows for proper air circulation and avoids any potential harm to the plants.

During windy conditions, it is essential to secure the shade cloth in place. Twine or rocks can be used to anchor the corners and edges of the cloth, ensuring it remains in position. This not only prevents damage to the cloth but also guarantees continuous protection for the plants.

Alternative Options For Shade Cloth

If shade cloth is not readily available, there are alternative options that can be used to provide temporary shade for plants.

One such option is using old window screens as makeshift shade cloth. These screens can be propped up or hung with the help of stakes or other supporting structures, offering a temporary solution for plant protection.

Another alternative method is the use of row covers. Row covers are lightweight materials that not only provide shade but also protect plants from pests. They come in different thicknesses, with heavier covers offering increased protection against pests and sunlight.

Benefits And Types Of Row Covers

Row covers made from polypropylene, polyester, or polyethylene are commonly used for plant protection. These covers can be supported by curved hoops made of flexible plastic, creating a tunnel-like structure that holds up the covers over the plants.

There are two types of row covers: lightweight covers that block 5% to 15% of sunlight, and heavyweight covers that block 30% to 50% of sunlight. The choice of cover should be based on the specific needs of the plants and the intensity of sunlight in the area.

Row covers not only protect plants from excessive sunlight but also act as a barrier against insects and other pests. This can be particularly beneficial during the early stages of plant growth when they are most vulnerable to damage.

Additional Techniques For Plant Protection

In addition to shade cloth and row covers, there are other techniques that can be used to protect plants from the sun. Building a shade structure, such as an A-frame or lean-to trellis, can provide shade for plants. Vining plants can be trained to climb up the trellis and provide additional shade.

Mulching with straw is another effective method to protect plants from heat and sun exposure. Mulch acts as an insulator, keeping the soil cooler and reducing moisture evaporation. When applying mulch, it is best to do so in the morning to keep the soil cool throughout the day. This technique is particularly advantageous for potato plants, as it protects the tubers from sun exposure.

A windbreak can also be constructed to shield plants from hot summer winds that can dry out leaves, especially for young seedlings. Creating a barrier using fences, hedges, or strategically placed structures can help redirect the wind and keep plants protected.

It is important to avoid fertilizing plants in dry soil, as this can lead to burning. Dry soil absorbs fertilizers more readily, increasing the risk of damage to the plants. Additionally, it is best to water plants early in the day to keep them cooler and reduce the chances of heat and sun damage. Wet soil remains cooler than dry soil and does not become crusty and dry when exposed to the sun.

For potted plants, it is recommended to move them into shaded areas during the hottest part of the day. This helps prevent excessive heat and sun exposure, which can be detrimental to the plants. By implementing these additional techniques, plants can thrive and remain protected from the harmful effects of the sun.
