5 Benefits of Using Recycled Rainwater in Your Garden


Gardens love water.

From your lawn to your plants and beyond, if your greenery can stay hydrated, then it’s sure to bloom to its fullest potential.

There are many sources of water that can be used in a garden, but the best is undoubtedly rainwater.

Here in the UK, we are all too familiar with a rainy afternoon, but a large percentage of us don’t do anything to keep hold of the rain that is coming down.

This is a big waste, as this water isn’t just free to use, but it also can benefit your garden in many ways.

Here at The Southwest London Gardener, we are proud to be natural gardeners, and that’s why we promote water collection systems that are ideal for allowing you to reuse rainwater.

But how can the recycled rainwater you gather in these systems help your garden?

We’ve created this guide to help you find out, so let’s take a look.

How to Recycle Rainwater

Recycling rainwater can be a complex process, or something very simple.

Which one you choose depends on your needs, the size of your garden, and many other factors.

If you only want to collect a small segment of water to keep a few of your plants happy and hydrated, then a bucket will do just fine. For something bigger, a rainwater collection system could be the key.

These are more complex and may contain things like a first flush diverter (this makes sure the first flush which often contains debris is diverted away), downspouts, filters, and more.

It is always a good idea to consult a professional who can come and assess your garden to ensure your rainwater collection system has the right design to maximise its effect across your plants and beyond.

5 Reasons Reusing Rainwater is a Great Idea

It is Helping the Planet

By recycling rainwater, you are reducing the strain on water supplies and lowering the demand for natural sources such as groundwater.

This is a huge reason that this process is good for the planet, but it isn’t the only one.

You also have to factor in the energy used to pump, treat, and distribute water, which is wiped out when you use recycled rainwater.

What you have to think is when it rains and a large abundance of water flows down your gutters into the drain, wouldn’t it be better if it could be put to good use? Uses such as feeding your hungry plants?

Well, that’s what a water collection system can provide.

It is Better for the Plants

Every garden enthusiast longs for the healthiest plants possible.

One way you can provide this is by switching from mains water to recycled rainwater.

This is water packed with the good stuff. In a nutshell, it is pure H20, with no added chemicals such as chlorine or fluorine that can sometimes be found in the water that sprays from your hose.

One feature rainwater does have though, is carbon dioxide, which is great for balancing the PH of alkaline souls and making them suitable for a much wider range of plants.

What you want to provide is the perfect environment for plants to grow and the ideal nutrients to aid them along the way, and rainwater is the perfect substance to help you do this.

It Can Save You Money

If you’re looking to save some pennies from your water bill, then you need to cut back on the mains water you are using.

To do this, and to maintain a healthy garden, you have to find a replacement, and there is no better one than using rainwater.

This is free water that falls from the sky and can be collected and stored to be used when it is needed.

Apart from the initial investment into the setup of your rainwater collection system, everything else is completely free, and your tap can remain firmly closed.

And this isn’t the only financial benefit. With a garden watering system in place, your use of water is often optimised and only used when needed. When using a hose, it is easy to spray away without too much care for how much water you are using.

This can cut down the amount of water used and leave you only using the amount they need.

It is a Great Lesson for Children

Climate change is a pressing problem and if you want to educate your children on some great eco-friendly ways to care for your garden, working with recycled rainwater is ideal.

There are many lessons you can teach them with this kind of set-up, including:

  • Understanding of the water cycle.
  • How water is used to boost plant growth.
  • Why recycling is great for the environment.

And there’s much more as well, so why not provide a hands-on approach and really provide an insight into not just how your garden works, but how the world does.

It Brings you Closer to Nature

Spending time in your garden is all about getting out into nature and feeling at one with the Earth.

In essence, you are using the rain that falls from the sky to feed your garden, and what is more natural and sustainable than that?

If you are a lover of all things natural, then this can really help you feel like you’re making the most out of your garden in this sense and allow you to use natural resources throughout.

Not only that, but your rainwater storage can also create a nice spot for local wildlife to come and grab a quick drink, as well as create a nice environment for native plants to really blossom.

You’re reducing the environmental impact of watering your garden and making the process more efficient in the process.
