If you have ever read this blog before you probably know my opinion that in general, growing a vegetable garden does not save you money. By the time you pay for water, buy the plants (or seeds), pay for fertiliser (organic or not), and gardening tools and equipment (such as trellising), my opinion is that at best, you come out even. That’s if you are comparing apples to apples, so to speak.
However, apples aren’t really apples. An organic apple grown in a home garden is not the same as an apple bought from the supermarket. If you grow heirloom fruit and veggies, the varieties you can choose are so different, they are not comparable. I think they taste better and growing your own is generally more sustainable (although it is not necessarily healthier – research shows that the basic nutritional elements between organic and conventional vegetables are very similar).
So, I grow my own veggies because it is fun, because I like to have more choice than the supermarket offers, and because it is a sustainable hobby.
However, if you choose certain vegetables carefully, you can save some money on your fresh produce bills. This is even more important in today’s inflationary environment. These plants can be grown in the ground, in raised beds, or in containers – also important if you are renting.
Top veggies to grow to save money
Social media has reported iceberg lettuces (the worst lettuce of all) for sale at an astounding $8.99 each in parts of Australia. While I would not grow iceberg, which requires a lot of water and fertiliser for very little nutritional return, there are many lettuce varieties that can be grown at home easily with almost no effort.
I like to grow Cos lettuces (currently, Paris Island Red) and a lettuce called Australian Yellow in a raised bed and an old wheelbarrow in the back yard. But lettuce is so easy you can pretty much grow it in any container during cooler months. You can grow it from punnets, but the easiest and cheapest thing to do is grow it from seed. Lettuces come in a huge variety in seed from from both garden retailers and online, and are a good deal. Lettuce seed packs usually come with between 500 and 1000 seeds in a packet. I plant half a packet at a time, sprinkling the seeds liberally over the soil (I don’t bother with rows), and then lightly covering with soil. Water in, then wait for them to pop up over the next week. As they grow, feed with organic liquid fertiliser once a week. Make sure to keep them moist, as lettuce that is not kept moist will become bitter and gross.
You can be picking your own lettuce within four weeks, depending on how cold it is. Pick the leaves you need as you need, and let the plant continue to grow. Try to pick a few leaves from each plant, rather than picking a whole salad from the one plant, so your crop produces evenly. Grow your own lettuce from Autumn to Spring, then let a couple of plants go to seed as the weather warms up. If you are growing an heirloom variety, you will be able to save the seeds for your next crop.
My family loves spicy food, especially my husband. We eat spicy food almost every night. A packet of chillies (sold in plastic, natch), costs $6.50 at my local supermarket – or $32.50 a kilo. If you eat a lot of chillies, that’s a pretty costly habit.
One chilli bush will produce well over a kilogram of chillies for about $5 a plant. They don’t usually require much in the way of care, aside from water in the hot weather.
If your plant produces more than you can eat at one time, they can be frozen or dried for longer storage. I do both. If you freeze, you can use them straight from the freezer.
Lebanese eggplant are the most prolific eggplant I have grown. While perhaps not as pretty or as widely useful as the globe eggplant (for stuffing or moussaka, they are definitely not as useful), they grow like crazy. This season we had four plants and at least one eggplant-based dish a week from early Summer through to mid-Autumn. Obviously if you’re not a fan of eggplant, that’s not a good deal, but for us it was great. We bought a punnet of four eggplants for about $3.50 from our local supermarket, and planted them in an unobtrusive corner of the garden. Aside from water and a side dressing of pelletised chicken manure once over the season, we left them alone the whole Summer except to go out and pick a bowlful every couple of days. Too easy!
Your mileage may vary on kale. I don’t mind it, but I don’t love it. I still grow it, because it’s very healthy and quite useful. It’s also pretty expensive – anywhere from $3-$5 a bunch, depending on the season.
Kale can be grown easily from seed and in containers. Last Winter I grew it entirely in pots. However, my view is that it does grow better in the ground than in containers.
Growing from seed is simple. Plant in seed-raising mix, and keep moist while they germinate. I use a heat mat to help the seeds along.
Kale is easy to buy in punnets as well. There are several varieties: Red Russian, Curly Kale (most common), Tuscan (also known as Cavolo Nero or Dinosaur Kale). I prefer to grow Tuscan kale, as I prefer the flavour and texture.
I freeze kale in bags. I just wash it and chop it up, and put it in bags in the freezer, using it from frozen.
Some people might not like chard, preferring the less strongly flavoured spinach. But silverbeet is a tougher, easier to grow plant than spinach, and is also beautiful in the garden, especially if you grow the rainbow variety (which is an Australian breed, btw). It holds up much better in the patch than spinach.
The other great thing about chard is that it grows really easily and quickly from seed, and leaves can be cut as you need it from the main plant over the season for a really long period.
Silverbeet seeds are little blocky, cube-like seeds. Soak them for a few hours in warm water before planting, then you can either plant in seed-raising mix, or plant direct where you want it to grow.
When it germinates, water with a weak solution of organic liquid fertiliser each week.
I grow a variety of different herbs in my garden. I grow almost all of them in the ground, but you can also grow them all in pots. A small plastic blister-pack of soft herbs like thyme or parsley from my local costs $2.00 per 10 grams. That is $200 per kilogram, people. For the easiest plants in the world to grow. If you were to set aside $10 a week to start creating a potted herb garden at home ($4 for a plant, and the rest for the pot/soil), you would be very quickly better off than paying anything for a packet of these already dying herbs from the supermarket. If you plant them in the ground, you won’t need the pot.
I have many herbs in my garden because I have the space and I enjoy the freedom to pick and choose what I want to use anytime. I also just like to grow different things for fun. But even if you limit the herbs you grow at home to the three or four herbs you most commonly cook with, you will save some cash.
