Not just that, there will be severe damage to how the plants function.

So much so that it impacts their development in major ways.

This isn’t to say that there is going to lead to droopy leaves only.

The heat leads to them having stunted growth.

And with that leaf drop, leaf scald as well as failure to flower means that there is a failure to produce seeds also.

All of these things accumulate and lead to the condition getting worse with time.

Heat stress happens during the high daytime temperatures.

At nighttime temperatures, it is basically going to be much cooler and better.

This is due to the exposure control and will also lead to better management and balance of the temperature.

So how do we do that?

I want to share some leading steps and ways to make a difference:

  • Make sure you are putting the heat sensitive plants in garden beds which are receiving afternoon shade.
  • This is done for houses including sheds, fences, among others.
  • Also you should be planting the garden beds in places which have dappled afternoon light.
  • You should also make use of ways where you are planting shorter, heat sensitive crops under the shade of taller and heat-loving crops. For instance you are planning salad greens under climbing squash. This really makes a difference.

  • You will also look into what are the tap-rooted plants and how can you draw the water which actually goes deeper into the soil.
  • Also did you know that tap-rooted plants are those which will be drawing water faster from deeper soil
  • Some young plants are those which don’t have very deep root development. In such cases, it is best if you are establishing plants which have a large network of roots.
  • Having so allows you to draw moisture in large ways from the soil. This stands strong for many such plants and you need to create a proper manner of giving enough moisture to plants. So that heat stress does not get them to wilt so strongly.
