I’ve spent a lot of time in my garden over the past 7.5 years. And a lot of cash, if I’m honest. I can’t say how much exactly. By the time I add up the cost of plants, removing trees, building a retaining wall, installing a chook shed (which we were lucky enough to score secondhand from our neighbour), tools, trellises, even more plants, etc…the cost must be in the shillions (that’s a number my youngest invented at the age of four, when trying to envision the largest number possible).
While I don’t regret any of these expenses, I do think there are some items that were better investments than others. They have raised both the value of our home and improved the overall look or productiveness of my garden.
Compost bins and compost worms
I have three black ‘dalek’ style compost bins that are always in rotation. Two cost $40 each from Bunnos, and the other was free from my local Buy Nothing group. I continually add garden trimmings, coffee grounds, tea leaves, chicken shed waste, and kitchen scraps to the bins. I turn them every time I clean out the chook shed, so roughly every two weeks. By ‘turn’, I mean I tip them over, move them around, pull out the ready-to-use compost, and shovel the rest back in the bins. Some weeks I might get a few buckets out of three bins, and at other times, a wheelbarrow load. I tip it on to whichever part of the garden looks like it needs it the most. Over the course of the year, the whole garden gets a topdressing of homemade compost. I don’t dig it in – I just tip it on top of the existing soil and let it weather in.
I add a box of 1000 compost worms to the bins every couple of years, where they happily breed and chew through the compost. I don’t bother with worm juice or a worm farm; I am perfectly happy just tossing them back in as I turn the compost. A box of 1000 worms costs about $50.
For an investment of $180 over 7.5 years (2x boxes compost worms + 2 x compost bins = roughly $25 per annum), I have homemade compost for my front and backyards. The other important benefit is that we divert kitchen and garden waste from landfill, reducing our family’s carbon footprint. Most weeks, our red bin (garbage) has only one bag.
When we first moved to our property, we paid a professional arborist $3500 to remove five trees. We researched several arborists, and received quotes. One guy quoted us $1000. When he visited us, he was clearly a dodgy operator and we turned him down, even though his quote was less than a third of the other company. At the time, $3500 was a lot of money to spend before we even started our garden. But the trees there were not safe or appropriate for the property, and prevented us growing anything productive. We forked out the extra cash, and a team of professional arborists safety removed the trees. I still think it was worth the extra money.
Good quality trees
You can buy trees from many places. Even supermarkets sometimes sell fruit trees at a bargain price. I’m not averse to picking up a bargain punnet of petunias from my local supermarket, believe me. It might seem that a tree is a tree, and that all that counts is the variety. However, I have learned the hard way that is not the case. Specialist tree nurseries invest in good quality root stock and hire qualified staff with expertise in varieties for your area. I buy most of my fruit trees from a local nursery that understands my soil and weather conditions, and provides advice on growing conditions and care. I pay for that advice by paying more for the trees I buy from them, but it has been worth it. Every tree I have bought from them has thrived.
To compare, I have a lime tree bought from my local specialty tree nursery, and a lemon tree bought from a supermarket. Both were planted at roughly the same time. One is in the front yard and one in the back yard. The lemon tree is a sad, spindly little thing, with not a single flower or fruit to be seen. I have fed it and watered it – and nada. The lime tree, even after fighting off a scale infestation and a leaf miner attack, has glossy dark leaves and has produced its first full crop of juicy limes. It is currently flowering again, getting ready to produce its second crop. Arguably the back yard and the front yard have different conditions. But not that different. I’m getting ready to yank that lemon tree out and replace it with a new tree, from a good nursery. I’m not one to harp on sunk costs.
This should be obvious, but cheap tools are not worth it. I have a solid hard wood handled garden fork that that I bought from the Digger’s Club five years ago, and aside from the muck on it, still looks new. It cost me about $80, but is worth every cent. I can buy a fork from Bunnos for ten bucks, but the handle will snap in no time. On cheap forks, the tines bend very easily, leaving you with an annoying fork that digs and turns unevenly. I dig with my Digger’s fork a lot, and the tines don’t bend, even when digging over hard or rocky soil. I feel confident that this fork will still be in tip-top shape in another five years. I intend to replace my other tools with Digger’s tools as they die, because I know the investment will be worth the extra cash.
Potting mix and fertilisers
Certain things can be purchased more cheaply for sure, but potting mix is not one of them. I know, because I have bought and tested almost all available to me. You will hear many garden experts say to buy ‘premium’ potting mix. I used to think, ‘well, sure, if you’re made of money.’ Then I discovered that the cheap three-dollar bags of potting soil are basically pressed bark sweepings, and do your plants no favours. Cheaper potting mix dries out very quickly, becomes hydrophobic, and leaves your plants hungry and thirsty. Spending money on good plants and not spending on the soil ends up costing you more in the end.
Look for the ‘red ticks’ on the bag. That means it’s a premium mix. ‘Premium’ usually means it has added soil wetting agents such as additional coir, and slow release fertiliser. Of course, you could add this to a cheaper mix yourself, but then you have just raised the cost of the cheaper mix anyway.
I also spend money on good quality, pure organic fertilisers such as pelletised chicken manure (also called Dynamic Lifter or other versions), Blood & Bone, and liquid tonics and fertilisers. I don’t buy brands that say they are ‘Blood & Bone-based’ as this can mean the manufacturer has added cheap fillers to the bag to lower the cost. These do nothing for your garden and may attract pests. It’s worth spending more to get a pure product.
Some gardeners prefer not to use Blood & Bone products, and as a vegetarian, I understand that. There are vegan fertilisers available. However, I am not a vegan, and neither are soil micro-organisms. I am not opposed to using animal products in my garden so long as they are organic. I use a product called ‘Charlie Carp,’ that is made from European Carp, a fish that is a pest and pollutes our waterways, and I also use animal manures such as sheep and chicken. Use what you are comfortable with and that sits with your values. Buy the best products that you can afford to feed your soil. Feeding your soil is the best investment you can make in your garden.
