The temperatures in summer can be extremely soaring for all of us, and the same applies to plants as well. If you are working inside a greenhouse, you will know what we are talking about.
Temperatures within this house are several times higher than outside. In the middle of growing season, such hot sunny weathers are sure not a welcome to anyone, it strains the plants and their growth table is altered.
With more people concentrating on terrace gardening and also building greenhouses, the hot summers are really not a welcoming note to the kitchen growers. For the sun-loving plant growers like tomatoes and cucumbers too, they have a limit to the amount to sunlight needed. If temperatures rise above 90F then the sun loving plants to fail and fall for damage. So what do you do? We give you certain tips to keep your plants cool in this hot sunny weather and don’t alter the yield of your precious produce.
Just like humans, plants too can't withstand very high temperatures, they wilt and dry out due to lack of proper nutrients, extreme hotness and less moisture. Please try to adapt these steps to a better system within the greenhouse in summer and keep your plants safe and happy.
Ventilation is the best way to combat the heat, by providing plants with a good flow of fresh air. Roof vents, side vents and the greenhouse door can create the necessary airflow within the house.
After certain temperatures, like 81F many plants start to fall off due to unbearable excess heat, so it’s advised to keep a thermometer on hand to monitor ad regulate the condition. On a sunny day try to be an early bird to open up all the vents and doors to regulate the temperature before any damage, and to prevent pests and cats from dropping in, please use nets. But make sure the nets allow pollinators inside.
Automatic openers are not suitable here.
Shading a greenhouse:
Shading is the next tool that you can use to reduce the heat. Shading roofs with some paints that filter out some of the sunlight is a good way to heat proof your greenhouse. It's quick and cost effective too. You can add layers of paint as the summer progress and wash and remove it off once it wades down. But see if it suits your greenhouse and then consider the option.
Blinds can also be used to ward off excess sunlight. There are both internal and external blinds. External ones are most effective in warding off the sunlight, by filtering it before they reach the glass and reach to the plants inside. These blinds can later be removed to adjust the sunlight needs.
Damping a greenhouse:
Have you ever heard and tried this? Damping the places to keep plants cool! Damping down as it is called as is a process of wetting the surfaces like paths and staging by using water. This process raises the humidity, which in turn increases the moisture level inside the house.
Raising humidity also has other benefits like killing those pests that thrive in hot and dry conditions. Although you can do it as often as possible, standing up high in the hot sun all yourself will cause problems to you. So it’s best to dampen once in the morning and evening.
Avoid Water stress:
Watering plants with enough water in the summers in essential to keep them happy! Plants use an effective tool to keep its moisture locked in summers, through transpiration. The lack of moisture through the leaves help the plants cool down from external heat. The reduction in this ability of the plant can make it wilt and over heat.
You must be looking around for tell-tales of plants losing water, like wilting and drying out. Check for the leaves, scorched leaves or young leaves or foliage falling out in dryness. The above said measures will surely combat the heat induced stress in plants and will enable a happy growth in them.
As they say, don’t overdo anything. Over watering will also cause problems like a weak root or the essential nutrients in the soil being washed away with excess water. So the trick is to do everything optimally.
