If you’re environmentally conscious, you know the importance of using natural resources in all parts of your life, including gardening.
Well, you know how you get a break from watering your plants when it rains? Why not use rainwater as a main irrigation source when gardening?
Harvesting rainwater is easier than you might expect. Even beginners can master it on the first try. So, keep reading to learn all about rainwater harvesting!
How to Master Rainwater Harvesting
There are numerous methods you can use to harvest rainwater. This depends on your climate and resources.
Here are my top methods for rainwater harvesting:
1 – Rain Barrels
One of the most popular rainwater collecting methods is rain barrels. If you already have a slanted roof and gutters, you won’t need to do any extra work!
Instead, all you have to do is install gutter guards and debris traps. Then, connect the gutters to a tank and let gravity do its thing.
This rooftop system would be an ideal harvesting method for particularly rainy locations. That’s because you’ll capture large volumes of water from a relatively small area, and you’ll get to use the clear rainwater around your home as well as your garden.
2 – Surface Runoff
If you’re looking for a way to alter the geography of your garden, harvest rainwater, and improve your soil quality, look no further than surface runoff harvesting.
As the name suggests, this method involves retaining and redirecting the rainwater through runoff systems into holding containers.
You can excavate an area in your garden and build small tunnels to redirect the rainwater into it. Alternatively, you might use pipes and barrels, similar to rooftop systems.
3 – Groundwater Recharge
Groundwater recharge is an exceptional method to improve your soil quality, even if you don’t plan on harvesting rainwater.
While you won’t be able to use the captured rainwater for anything else, your plants will definitely thank you.
The way groundwater recharge works is by letting rainwater penetrate deeper layers of the soil instead of evaporating. Then, this recharges the natural aquifer of the soil and hydrates your garden.
There are numerous ways to practice this method, including:
- Building a pond in your garden if you live in an area that rains frequently.
- Digging a tunnel system to irrigate your entire garden.
- Using gravel mulch and permeable pavements, allowing the rainwater to seep into the soil.
Why You Should Use Rainwater
After using any of the above techniques to harvest rainwater, you’ll be saving both your bank account and the environment.
That’s not all, though. Rainwater is a perfect irrigation method for the following reasons:
4 – Superior Quality
Rainwater is the healthiest type of water you can give your plants. Unlike tap water, it isn’t treated with harsh chemicals.
These chemicals might be healthy for us, but they’re toxic to plants. You might even notice your crop looking burnt and splotchy due to excess chloride in the water.
On the other hand, rainwater contains more oxygen and beneficial minerals, leading to the green and lush garden of your dreams.
Accordingly, if your plants just don’t seem to be doing well no matter what you try, try switching to rainwater to reap the natural benefits.
5 – Affordability
Investing in a rainwater harvesting system can seem expensive at first. However, you’ll be saving a fortune in the long run.
For starters, think of the significantly lower water bills you’ll be getting. Furthermore, since your garden will become healthier, you won’t need extra effort and money on plant care.
6 – Sustainability
Harvesting rainwater is one of the best ways to help the environment while benefiting yourself.
By using rainwater to irrigate your garden, you’re decreasing the demand for freshwater supplies. You’re also conserving energy usage, as pumping and treating freshwater requires substantial energy input.
What’s more, harvesting rainwater prevents it from becoming runoff, which can damage water-draining systems and lead to pollution.
Final Thoughts
Rainwater harvesting is a great way to start your sustainable gardening journey. Even if you’re a beginner, most rainwater collection methods require zero effort and almost no resources.
Then, you’ll be met with some exceptional benefits, including reduced water and energy bills, healthier plants, and more savings. The best part is that you’ll also be helping the environment!
