7 Tips for a Water Efficient Garden

As we head into summer here in the southern hemisphere our poor gardens get dried out from the harsh sun and if we’re not careful our plants get rather sad looking. However unfortunately water is something we have to use carefully here in Australia (and much of the world), so I’m here to help with my top tips for a water efficient garden.

With a few small changes to how you set up and manage your garden you can still have a beautiful and productive garden without having to use bucketloads of water!

7 Tips for a Water Efficient Garden

1. Water at the right time of day

Watering in the coolest parts of the day is the most efficient way to water as it allows it to properly seep into the soil before the sun comes out and evaporates water from the surface. In summer watering either very early in the morning or in the evening is best, but in winter it’s best to water in the morning as it can freeze in the evening if the air is too cold overnight. Definitely avoid watering at the peak of the summer heat as it won’t get a chance to soak into the soil and can result in leaves getting fried.

2. Choose the right plants

For non-productive parts of your garden lean towards native plants as not only do these support our biodiversity but they are designed for our climate and therefore generally need much less water than introduced species. Make sure they are native to your area though, plants that are native to tropical Queensland will still need lots of water down here in Melbourne!

There are also plenty of drought tolerant plants that aren’t always native (like succulents) that are excellent options as well.

3. Use mulch

First of all make sure to use good quality soil full of compost and manure, as this will increase the ability of the soil to retain moisture, meaning you won’t have to water quite so often. Then, top your soil with mulch, as this seriously helps retain moisture (up to 70% more!) as the bare soil will dry out much quicker and heat up a lot more. Mulch also helps stop weeds from popping out, which will compete with your plants for moisture.

Once you have mulch down you should push the mulch aside and check how dry the soil is before watering each time, as it can be tricky to tell how much water is needed when you can’t directly see the soil. This is particularly important if you’re new to mulching your garden and you might be surprised at how little you now need to water!

4. Try less regular, deep watering

In terms of actually watering the plants, try and avoid doing regular small watering and instead water less regularly but much deeper. This allows the water to really seep down into the soil, helping to establish stronger, deeper roots which assist in keeping your plants healthy. This doesn’t work for all plant types as some can’t cope with being ‘drowned’ so do read up on the specifics, but for most deep-rooted plants it works really well.

5. Group plants by water needs

Another great way to reduce your water use is to group your plants by their watering needs. This means that plants that like a deep watering can still have that occur without having to waste water on nearby light-drinking plants. This is also excellent as it means you only have to water some parts of your garden each time, which is always a bonus (particularly if you have a large garden!).

6. Avoid sprinklers

Sprinklers seem like a great idea as you can set them on timers and get your watering down in the cool parts of the day, however they are incredibly wasteful. So much of the water gets blown away in the wind, lands on pathways or just generally doesn’t go where you really need it to. A much better option is a dripper system as they tend to sit at the base of plants, providing the water right where it is actually needed. They also provide water in slower, smaller amounts which can allow it to properly soak into the soil and reduces water runoff significantly.

If you are using an irrigation system make sure you change the setting seasonally to make sure you’re not over watering in winter or under watering in summer. If possible also install a sensor to avoid the system coming on after it has rained, or when the soil doesn’t need any additional watering. If you don’t have a sensor make sure to switch your system off when it has been raining!

7. Capture and reuse rainfall

The wonderful thing about water is that we do get it free from the sky (even if it’s in reducing amounts) so finding a way to capture it and then reuse it on your plants is a great step towards a water efficient garden. This could be as simple as putting out buckets when you know it is going to rain and using that over the next few days, or through installing a rainwater tank.

You can now get tanks that are really slimline and even almost architectural looking, so you don’t even need to hide them behind your house any more! Of course if you are getting water tanks installed you might want to look into hooking them up to your washing machine or toilets as well, but even if that’s not possible they are still excellent for your garden!

    The seeds we planted direct about a month ago are finally big enough to be mulched. A job for the weekend!

    It was interesting to learn that there are sensors that can tell the irrigation system to not water if it’s rained. It makes me wonder if farmers have similar systems for their irrigation systems. I’ll bet they’ve got much more complicated systems with all sorts of parts that might need replacement.
