Yesterday, we visited the Royal Botanical Gardens in Melbourne.

The weather and gardens were beautiful, but we really noticed how lush and green the lawns were. It was inviting and refreshing to see all that green - and the number of people picnicking there proved the appeal.

What was interesting was to see various notices around the gardens referring to their water usage. They have reduced their water consumption in the last 10 years by about 50% through a system of testing, training staff and improved horticultural practices.

It is an interesting thought that checking your irrigation systems can make a difference to your water consumption. of course, the Botanical Gardens have major irrigation systems to check - they manually check the pressure level of all sprinklers for instance.

However, at home you can check the following things:

• do fittings fit your tap so that there are no drips and leaks when you use a hose or system?
• is your hose in good condition without leaks?
• if you have a watering system, is every sprinkler head clean and clear to allow water flow?
• does your tap timer turn the tap completely off when it finishes?
• does your tap drip?
• do all sprinkler heads point towards plants as appropriate - as plants grow and gardens change, the heads may need to be adjusted

When you consider that a leaking tap can waste up to 20,000 litres of water a year, these regular checks can save a significant amount of water.

How wonderful it was to go to sleep last night with the sound of rain on the roof, and to look out the window this morning and see damp ground!

Did you make the most of the rainfall?

Some things you may have done were:

• put pot plants in open areas
• put out some buckets or containers to catch water
• remove the cover from your pool to get a top up
• danced in the rain, enjoy the feeling of rain and be grateful for the water in our gardens

The cost of a litre of water is actually very low in Australia - which means that saving water by harvesting rain probably won’t save you a huge amount of water. That is, you won’t save a lot on your water usage charges.

However, collecting water in a tank can save you money in other ways:

• the amount of water you use form the mains is used to determine the amount of sewerage disposal you are charged. The assumption is that if you use more water, you will put more into the waste system, so reducing water usage will save you in sewerage costs
• a healthy garden can provide shading for your house which reduces your need for (and therefore the expense associated with ) air conditioning
• having water for growing your own fruit and vegetables will save you money from buying food at the shops - especially if you prefer organic options. It also is better for the environment as there is less transportation and farming machine costs.
• you can wash your car at home instead of at a commercial car wash - a much cheaper option!
• keeping soil around your home moist (by watering gardens) may prevent cracks in your house resulting from dried out soil and foundations. Fixing cracks in brickwork and plaster can be expensive and time consuming, and that doesn’t count re-stumping or potential dangers from instability either.

For many people, just having a lush or at least a living garden is enough reason to use water on your plants. But there are actually some other advantages to keeping the soil moist.

If the land around your home gets overly dry, it can lead to changes in the soil which can affect the foundations of the house - cracks in the plaster is just a symptom of this. Moisture in the soil maintains stability of the ground and house.

Having a green and moist garden also offers a reduced risk of fire - dry and dead wood burns more readily than green, moist wood.

Of course, just having a nice environment, a connection with nature and a safer, welcoming environment for the kids are also important reasons for ensuring there is enough water for our gardens as well as our personal needs.
