How Much Heat Can Plants Tolerate? 

Different plants have different temperature tolerance points. Some need warm climates and others need colder climates. With the help of this you can protect your plants properly. The green leafy plants such as radish, cabbage, broccoli, etc prefer cold weather. These plants can stay in good condition at 50-60° F. If the temperature goes over 75°F, it will start to spoil. And over 90°F will definitely make them dry and die. 

On the other hand, plants such as tomatoes, peppers, and beans will flourish in 75°-90° F. But, if it is extremely hot, these plants can also die. They become less productive, damaged and experience flower drop, etc. Whatever type of plants are, they need extra care in summer, especially when they’re young one. So, keep your eyes on the seedlings and start protecting them from the dangerous heat waves. 

Best Ways to Protect Garden Plants From Heat Waves 

Now, we will discuss those important methods with which you can easily protect your plants. And yes, don’t wait for the extreme level, start doing the task when the weather becomes 10-15° warmer. We have listed the quick and easy steps, you need to pick anyone which will be suitable for your garden. In some cases, a few tips will be useful, so try those which are enough to keep your garden green. 

Water Deeply Regularly 

The most simple method is water deeply, as we need water to survive, in the same way plants require it too. Your plants will be protected if it’s completely moisture and for that you should keep watering. Don’t use a pressure pipe to pour a high amount of water, instead use slow and long water. In this method, water will go deeply and the more moist will remain within the garden bed.

The more water will help the plant’s root to grow deeply, having deep roots will absorb more nutrients and water from the soil. And deeply damped soil can handle high temperatures and restrict plants from dryness. 

So, water in your garden twice per week or four days in a week. If you do deep watering, you won’t need to water daily. Maintain soil modesty damp all the times, but don’t make it soggy or completely dry. You can also set drip irrigation to keep soil moisture. In Drip irrigation, emitters keep dripping the water into the soil at root. If your plant will get sufficient water level, its productivity will increase and also of good quality. 

Water Before/After Heat Wave 

Don’t make a mistake, if it’s suggested to water daily or on a routine basis doesn’t mean that you water garden plants anytime. Water your plant either in the morning or evening. If you water them before heat waves, they will have ample time to soak up the water so that the soil has moisture for a long time.

Don’t be confused if you see them pretty sad during the afternoon, it’s because of the high temperature but it doesn’t require water.

Once sunsets, your plant will smile again, and more water can make them weak. As we need food to survive, it doesn’t support overeating. In the similar way, plants need water, that’s not meant to soak them in water every time. 

Before watering them, check the moisture level of soil, deep your finger in the soil upto 1-2 inches, if it’s wet means supporting a good moisture level. And in the evening, water when soil becomes cold, otherwise it will produce more heat and definitely be the reason behind spoilage. 

Avoid Watering at Noon 

I’m repeating it, don’t water if it’s hot noon time. Let me explain how this will damage your plants. When there is water drop on the leaves or any part of the plant, it will magnify the heat and cause sunburn, which you can see on leaves, how they will convert like someone burns them under fire. And don’t pour water directly on the plants, instead put it directly into the roots. 

When you water at noon, most of the water evaporates before reaching the roots. And don’t water just after sunsets, make sure water will completely soak through soil. If it is wet for longer, fungal issues may occur during the night. Best timing is before 10 A.M. and in the evening after 4 P.M., but not at night. 

Don’t Cut Taller Grass 

If there are taller Grass in your garden, let them stay. It’s good for your garden and also saves you time. Longer grass will keep soil moisture as no sunlight directly falls on the land which maintains the water level. Second thing is, if there is grass, there will be no room for weeds. And the last positive point is, it will reduce the impact of blazing sun and keep the garden cooler. 

If there is a huge amount of grass, it will protect your plants as well from the heat waves. And remove dull blades of grasses as it can harm other plant’s leaves. Water these grass twice in a week and keep the height 3-4 inches to cover the whole soil. 

Provide Shade to Plants

Shading anything during summer or heat waves, it will keep them cool and protect from harmful sun rays. If you use shades to protect your garden, it will reduce the intensity of sunlight and heat. Retain moisture and keep soils cool, in fact restrict bad impact of sunlights. Besides these, it also prevents sunburns, which we can usually see on fruits, how they look like half cooked under the hot sun. You can use various ways to provide shades to your plants. 

Use bedsheets or any light cloth over stakes or any support. Or you can use large canopies, you can even use a beach umbrella. Anything which will block the sun lights but allow a good air flow. If you want to keep this shade structure for a longer time, it’s better to use such materials which allow some sunlight which is essential for plants. Or you can just move some plants under the shaded area. 

Do Mulching to Reduce Heat 

Mulching can retain the soil moisture, as it restricts evaporation. It also prevents weeds from growing and provides more nutrients to the plants. Mulch is an effective and natural option of fertilizer. And as it will keep the soil moistures, it will require less water to thrive. If roots have more water, it will keep the whole plant healthy. 

Use a thick layer of mulch to cover soil near the roots. Leave a gap of 2 inches from the base of plants so that it can get air as well. Don’t go for the artificial weed mats, it will limit water to reach the roots. Put the mulch over newspapers and don’t forget to remove weeds before mulching. Prefer light straw or sawdust which is good for the passage of light too. 

Avoid Pruning 

We all know pruning is good for new growth, but it isn’t good for all weather. You can prune plants during the rainy or spring season. If you do it in summer, it may worsen the situation. Don’t prun, in place of that, cut dead branches, separate dry leaves, etc. And to prune, use a disinfected and sharp blade. You may leave some yellow faded leaves, but don’t try to give a new shape to your plant. 

If your garden plants are overgrown, prune it before heat waves, better to do in winters. They will have enough time to regrow. Although you can cut out the weeds, these weeds can absorb a great quantity of nutrients and water from the soil. Sometimes even it can convert the land to barren land. 

Ignore Soil Activity 

If you disturb soil during hot summer, it will reduce moisture in the soil. When you do anything such as digging, weeding, planting or transporting plants, it will release the trapped water. And the newly planted or seedling plants can’t grow easily or even die under the low moisture or water level. If you are planning to remove weeds, don’t pull it out completely. Instead cut using a sharp object, and don’t go for a new plant. 

It’s better to avoid soil activities when it’s too hot outside. It’s not only affecting your garden, it’s actually harming your body too. And if it’s too necessary just in case of removal of fungal or spoiled plants, do it when it’s morning and make sure soil is well hydrated, and water once you are done. It won’t reduce moisture and also have sufficient nutrients.
