The sudden arrival of heat can catch us unprepared and cause damage to our crops. Sun and heat can depress plant tissues or evenburn them. The plants, due to the strong sun and the heat, quickly dehydrate, the leaves turn yellow and fall prematurely. With dehydration, the cells of the plant tissues lose the so-called "turgor "and the foliage loses its tone or even withers.
With the arrival of high temperatures, you need to be ready forprotect plants from the sun and heat, on this page we will see how.
How to protect plants from the sun: instructions for saving plants from the heat and protecting them from the sun. Guide for potted and vegetable garden plants.
Just as in winter we do our utmost to create warm greenhouses and spread veils ofnon-woven fabric, in the summer it is important to strive for save the plants from the heat is protect them from the sun.
How to protect plants from the sun
Increase the water intake
The first thing to do forprotect plants from heat and sunis the increase in the frequency and intensity of irrigation.
Water the plants in the coolest hours of the day: early in the morning or in the evening. The water should be administered during these times because irrigating at noon would not make sense: the water would not be able to penetrate the ground and would not contribute to the phenomenon ofcell turgormentioned before.
Be generous with water but be careful not to create stagnations and puddles: wait for the soil to have absorbed all the water to continue to administer it until the soil is saturated.
Moisture: nebulizers and mulching
On the days when theSunit beats faster and the temperature is skyrocketing, sprayed with water on the foliage of the plant. Choose water that is not very calcareous (tap water is fine but only if you leave itrestfor 24 - 48 hours before administration).
This operation must be performed in the evening otherwise the water droplets cause the so-called "lens effect" by amplifying the sun's rays and damaging the plant.
To increase the moisture levels in the soil we recommend using mulch. Avoid mulching with plastic (even if bio) because the plastic overheats easily and coming into contact with the collar of the plant ... it would burn it! Mulching, in summer, should be done with coarse pieces of bark or straw. Mulching is imperative to keep the soil moist and to protect the root system of plants from the damage ofSun.
Protect potted plants from heat and sun
Pot growers have an advantage: they can move the containers! The ideal position would be on the terrace or on a balcony in a shaded or semi-shaded position. Awnings or shading cloth, typical of Italian balconies, is very useful for protecting potted crops.
Those who grow in pots but in the garden can move the plants by choosing the best exposure in the summer: to the north.
For plants grown at home, choose the least hot position of the entire apartment: place the pots in a bright but not warm area. Be careful, however, not to place the plant in a room with an air conditioner. The ideal solution is to place the plants near a north-facing window.
Protect plants from the sun, crops in the garden and in the open field
Those who cultivate in the open canprotect plants from the sunusing shading nets. These nets are very tightly meshed and have a dual function: they protect plants from the sun and birds. In winter, the same nets can be used to protect crops from hail damage. If you don't know what we are talking about, to get an idea, consult the official page dedicated to Shading Nets on Amazon, there is no shortage of small sets for assembly in ecommerce.
