Often you can hear or read the information that many gardeners prefer to water the plants on the plot exclusively with rainwater. Many people are blindly guided by this statement, equipping various kinds of containers and devices for collecting rain. But most gardeners have some doubts and would like to receive answers to a number of questions. What is rainwater? What is its composition? Do I need to collect it in large quantities and for what? What are the rules for storing rainwater for successful use in the garden? We will consider all these issues in detail in order to draw a conclusion about the advisability of using rainwater on the site.
Rainwater is a liquid that is received together with precipitation – rain or snow. And how does this water get into the atmosphere? The moisture you water your plants with, as well as all ponds and groundwater, become the basis of rainwater during evaporation. Experts argue that rainwater has a unique, favorable composition, which is perfectly suited for irrigation. The thing is that it is much softer than the one that runs in the crane or settles in containers.
The miraculous effect of rain on humans has been spoken for many decades, based on basic statements regarding the benefits of rainfall. That is why people in ancient times believed that:
The city dwellers, who perfectly appreciated all the charms of the water supply and sewage systems, will not understand the villager who tries to take everything from nature as much as possible, using rainwater not only for irrigation but also as the main source of moisture for various needs. For example:
Of course, the direct purpose of rainwater is to water plants. The thing is that irrigation is free and you do not need to take any efforts — rain will water your plot independently, at no cost. Another thing is when a person tries to create special containers for collecting free water, then its use needs efforts, but much less than getting water from a well. It should be noted that rainwater has a very favorable effect on the growth of absolutely all plants, this number can even include those who are more finicky. During storage, rainwater can heat up under the influence of sunlight, therefore, plants do not have stress when watering, because the water gets the optimum temperature by itself, thereby bringing plants exceptional benefits.
Each owner has his own proven method of collecting rainwater, but the essence of the invention is the same – maximum collection of liquid from any roofs and outbuildings. You can do it with the help of rainstorms or special tanks located under the roof slope.
In addition, the tank should be made of safe materials – concrete, ceramics and fiberglass – it is worth considering all the points – covers or dampers that will help store water for a long time and also protect it from additional pollution with dust, foliage or other substances.
Alternatively, you can use ground and underground tanks, as they can collect rain as efficiently as possible without cluttering the area. An important bonus for hidden reservoirs during the summer heat is moderate temperature since underground water cannot overheat, which is difficult to say about ordinary containers with rainwater that are located near buildings.
This question worries every gardener who decided not only to save but also to pamper his plants with “healthy”, softer watering. Tanks can be stored on the ground, in the ground, or even located in the basement. The capacity of each container should be selected individually, depending on the purpose of use, as well as needs. The average rates are 750 liters and above.
The best storage tank is a container made of polyethylene, concrete, fiberglass and galvanized steel. Remember, light and heat should be kept to a minimum, so polyethylene is the best and most affordable option. If you decide to store rainwater all year round for the bathroom, do not forget to equip the tank with a special pump, and you can significantly save the consumption of tap water.
Remember, storage should be carried out carefully, out of all kinds of garbage and overflows. This is especially true for collecting water for domestic needs in the basement. It is recommended to create holes so that there is an exit of excess water.
If you store rainwater for irrigation at the site, then the container should be “preserved” with the advent of winter, so that it will serve you faithfully in the next season. Ordinary sand can serve as the heater.
Despite the positive aspects, there are a number of good reasons why rainwater can be dangerous for plants and humans. Unfortunately, industrial enterprises and car exhaust are the main sources of atmospheric pollution, which adversely affect the composition of rainwater, which is why people use the term “acid” rain, which obviously causes harm and danger.
Rainwater is not a return to the past but a good basis to use free moisture not only for plant growth but also for household needs. The construction of rainwater collection containers is the wise decision of the true gardener.
