Many hobby gardeners are afraid that the costs of irrigation will go over their necks. Why don't you just take rainwater?
Nobody can predict what the weather will be like in summer. Sometimes it rains like buckets, then another dry period follows. The fact is that your garden needs even watering. Long dry seasons do not like the vegetable garden or the lawn. But there are two ways you can water your garden with little effort and almost free of charge. The magic word is collecting rainwater and dosing it in a clever way.
Pouring expensive water from the tap becomes a thing of the past if you use the rainwater that is already there. To do this, collect the rainwater with appropriate containers (rain barrel), a purchase that will quickly pay off. This water is much healthier for your plants anyway, since it is not calcareous. In addition, the water is returned to the natural cycle.
Collect rainwater in the rain barrel
The simplest and most common way to collect rainwater is the rain barrel. Nowadays, a ton doesn't have to be big and ugly and look ugly in the garden. There are now rain barrels in various shapes and colors, so that they can be skilfully fitted into the garden picture.
Since the rain barrel is in most cases directly under the gutter, the size is always a bit dependent on the roof area. If this is larger, then you must also use a correspondingly large container. Rain barrels that cannot collect all rainwater are a waste, because the excess water flows next to it and sometimes even causes waterlogging.
Collect rainwater in the (underground) water tank
Another way to collect and use the rainwater in the garden is to set up a water tank. These “colossi” often hold several thousand liters and are therefore really only recommended for large gardens.
My tip: Sink the water tank in the ground and pour the rainwater in from the roof of the house.
If two garden lots are close together, it can also be worthwhile to do a deal with the neighbor. The acquisition costs for the water tank are shared, as is the rainwater collected. The practical thing about water tanks is the integrated pumps and devices, which saves you having to drag the irritating watering cans.
Cisterns or water tanks without an integrated pump can also be easily retrofitted with an external rainwater pump.
