I can make hundreds of litres of liquid plant food from just $12 worth of Dynamic Lifter pellets! This will buy a 10kg bag. Just add around four handfuls of pellets to a nine litre bucket of water and let steep for a couple of days, mixing occasionally. When you have a nice 'tea', pour a couple of litres of the liquid, into a nine litre watering can, top up with water and give your garden a drink. Repeat until all the 'tea' is gone, then add more water to the residual at the bottom of the bucket and repeat this process. As the mixture gets weaker, you can use on seedlings, vegetables and more delicate plants such as azaleas and gardenias. The 'weak' mixture can be used as a health tonic or sprayed directly onto the foliage of plants (remember not to spray if the weather is over 20 degrees Celsius, as this will burn the foliage). Once you get to the real weak stuff, simply pour the residual under a tree and water in well.

You can also make hundreds of litres of liquid fertiliser from a 10kg bag of Blood and Bone pellets at an initial cost of approxiamtely $1.20 per kilo. Compared to a litre bottle of liquid plant food (such as Seasol) which costs about $10 and will make just over 300 nine litre buckets (going on the manufacturer's average of 30ml per bucket), your bag will make many hundreds of buckets of first grade solution followed by many more second and third grade 'weak' solutions which are ideal for foliar feeding. A huge saving, which will give you enough fertiliser to last you a whole year or more!

Swapping roles with my husband forced him to start budgeting and to learn to take control of our finances!

My husband and I are happily married and are about to celebrate our 50th wedding anniversary, but there was a stage in our lives when we were raising three children and our finances were incredibly stretched, yet he refused to accept it.

One day there was no bacon for his breakfast (he likes bacon every day) and he lost his temper. Rather than get angry back, I wrote him a letter resigning as housekeeper, mother and wife and gave it to his secretary.

He finally agreed to talk and I got him to agree that for one month he would take responsibility for running the house on the budget I had been working on. It wasn't long before he asked 'How on earth do you manage? We need to reassess our finances'.

Since then we have always cooperated when it comes to getting through a tough period.

We have saved hundreds of dollars on making our daughters' room cosier! We are living in a rental property which we really like. However, our daughters are in the front bedroom and although it has a window, the room itself it doesn't get a lot of sunshine. This makes the room rather gloomy and feels damp in winter. We have a small heater which we use to try and take the chill off the bedroom before they go to bed but using it makes us feel we're watching money disappear before our eyes!

The perfect alternative would be spend hundreds of dollars on installing a skylight but since we're only renting, this really isn't an option.

A couple of weeks ago, I bought a couple of mirrors for $4 each to stick on the inside of a wardrobe. While I was preparing the area, I put the mirrors on the windowsill and to my astonishment, noticed how much brighter the room was when the sun hit the mirrors and bounced off the ceiling. It was as though I'd switched on a light!

By using those two mirrors and angling them slightly, I was able to bring sunshine and some warmth into the room. I have since purchased two more mirrors to make sure I take full advantage of the entire time that the sun hits the windowsill. The room is heaps brighter and feels more cheerful and warmer. It only cost $16 and it was all done with mirrors!

As a new member, I have saved $150 in my first week, thanks to the $21 Challenge! I thought I was careful with money until I discovered this site and realised how I could further improve my spending habits. I decided to give the $21 Challenge a go and it is now Thursday and I haven't been to the shops yet!

I have become a problem solver due to the fact that I must use what is in the fridge/freezer and pantry. I nearly buckled when my four year old wanted 'pink milk' and I had run out of Nestle Quick but no problem in the end. I found some rose pink food colouring and with just one drop - presto, pink milk! It does take some preparation because you are cooking from scratch but it is all worth it when your family tells you that the dinner you made tonight was the best, and is there any more?

My other dilemma was to use the three zucchinis in the crisper, so I made them into a slice. It was so easy to make and I had every ingredient on hand without even trying!

Zucchini Slice (serves 4-6)

3 zucchini (grated)
1 onion (grated)
1 potato (grated)
4 slices of ham/bacon (chopped)
1 cup of cheese (grated)
6 tablespoons flour (plain)
3 eggs
salt/pepper

Put all ingredients into a big bowl and mix really well. Pour into a quiche dish and cook in the oven for one hour at 160C. If you are vegetarian, simply leave out the ham. Simple, delicious and super cheap!

We had the chance to travel overseas several years ago but had to save $1000 to make it happen. On one income with two small children it seemed impossible. Then I had the brainwave - I didn't have to save $1000, I had to save $1.00 a thousand times! This was so much easier - a generic brand product at the grocery store, a chocolate bar at the petrol station and so on, soon added up and the savings contributed to a great family holiday.

I can make four litres of handwashing gel soap for under $1.00! To make your own liquid gel soap, grate a bar of Sunlight or generic laundry soap into a two litre ice cream container. Pour boiling water to half fill the container and mix to dissolve the soap. Carefully fill to the top with boiling water and mix well. Pour half the mixture into another two litre container and top up both with boiling water again. The gel is very thick once it sets, but a good consistency for its purpose. Store in the two litre containers and refill pump bottles as needed. One pump is all it needs to clean your hands and can even wash dirty dishes if you squirt into the sink!

Here's how to lose weight and save!

A couple of years ago I joined Weight Watchers and went to four meetings. Joining was free from a coupon in a magazine but the meetings cost something like $15.95 each. I couldn't get motivated!

A few weeks ago, as I was bucketing the bath water into the toilet cistern to save water (a tip from Simple Savings), I realised that I am doing the exact same thing that Weight Watchers meetings could not motivate me to do. At WW the main things they encourage you to do are to eat 10% less at meals (this also helps the budget at shopping time) and to exercise more (this comes from carting water between the bath and the toilet and using the rain water tank to water the vegie patch and so on).

I am now losing about half a kilogram a week without even trying and I'm not paying $16 to do it. In fact, I'm making other savings as well - our last water bill was $40 less than that for the same time last year.

What has also happened for me in the last few months is that while saving money I have also become better at time management - planning meals for a month and shopping with a list have cut out a lot of unnecessary trips to the shops (not to mention the extra expense). I have cut $60 from my husband's spending money by supplying his lunch every day, along with some soft drink, a large bottle of water and a snack. He is happy because he still has a small amount of 'sanity money' in his pocket to splurge with every week.

My food budget absorbed this when I switched from a lot of brand name products to BI-LO brand products - I save from as little as $0.10c per item up to a couple of dollars per item. The biggest savings I make come from bulk buying - last month BI-LO had five kilograms of potatoes for $5.00, but when I went to the greengrocers they had them at $6.00 for a 20 kilo bag. These lasted for about a month and I couldn't bring myself to go to the fish and chip shop when I had 15 kilograms of 'free' potatoes in the pantry, so we had home-made wedges instead, saving another $6.00.

The excitement of saving money has also inspired me to do the things that I don't enjoy so much, such as mending and ironing, and I am gradually working my way through every room and cupboard, taking inventory of what can be used and how best to use it in a way that will save me money. I never thought I would actually look forward to going through years of accumulated junk! By organising my house, I am becoming a 'cleanie' and leaving the old 'messy' me behind - and I am enjoying every minute of it!

My husband and I have set a goal to pay off our mortgage within five years. We have a way to go, but keeping this goal in mind has helped us to curb our spending.

I worked out that any amount I put on our mortgage is actually worth five times that amount due to the saving in interest. So when I am thinking about spending $20 on a top, I multiply this amount by five and realise that I do not want to spend $100 on a $20 top! That $20 would be much better invested if it was put into our mortgage.

Why buy lunch? With recipes as good as this, there's no need! I make this egg slice every few days to take to work, and I thought you might like to try it too.

Ingredients:

2 cups vegetables – just about anything will do. Leftover roast vegetables, steamed vegies, wilted salad... even raw stuff like grated carrot or chopped up tomato.

1/2 cup leftover meat, for example, bacon, fish or chicken

4 eggs, beaten

Grated cheese

Method:

Spread the vegetables and meat over the bottom of a greased square baking dish. Pour over the beaten egg, top with grated cheese and bake at 170C for about 30 minutes.

I take a quarter of this slice and some salad to work every day – it's yummy hot or cold. Thanks to the wide variety of vegetables you can use, no two slices are the same. It costs less than a dollar to make and the vegetables and protein keep me going for hours.

As a new singleton, I have learned not to let my pride stand in the way of making a new home for myself on a budget. I recently separated from my husband of 14 years and moved out of the family home. We share our four children week-about but I wanted to leave the family home as complete as I could for some sort of stability for the kids. With so little to now call my own I had no choice but to swallow my pride and 'put it out to the universe' that I needed quite a bit to furnish my new home.

At the op shop I purchased three Jason recliners, a telephone table, two tallboys, a desk, four bedside drawers, a single mattress and linen for the beds for $63, including delivery!

By word of mouth through friends I was given: a washing machine, microwave, crockery, glasses, towels, THREE TVs and a TV/stereo unit, a digital set top box, two stereos, a BBQ, a brand new gas bottle for the BBQ, a gorgeous white cast iron bed for my daughter, a queen size bed and three single beds, a computer, a bookshelf, a two seater couch, a bike and doonas for us all, as well as pillows. I gave away a few of the TVs and one of the stereos to people who needed it.

I also found that if you ask your friends if they have excess tea towels, coffee cups and so on, you'll find that they can often spare a few of these items.

Most importantly of all, I have learned that I don't need matching crockery or linen to make a home, just the basics and a lot of love!
