Companion Planting. Necessary or Not?
Author: Rob Date Posted:28 October 2018
Once the realm of the hardcore, home gardener, companion planting is now an incredibly popular practice – from beginner gardeners right up to large-scale agriculture. But, despite its popularity (it is huge in Europe), companion planting is often misunderstood, misused and misrepresented as the “cure-all solution” to problems in the patch.
So what is companion planting? Essentially, it’s a method of growing plants together, with the idea that they will assist each other in some way, like deterring pests, improving growth, enhancing flavour, attracting beneficial insects, fixing nitrogen, disrupting “patterns” and trap cropping. But, just as we have good neighbours, there are bad neighbours as well. Some plants really dislike each other, and shouldn’t be planted in close quarters, lest one of them struggle or meet its untimely demise.
Mythbusters – Does it Actually Work?
Now, the “Big Question”: does it work? Well, yes and no. There is a fairly limited amount of actual scientific information on companion planting, but it is safe to say that some combinations do seem to work, while others can be a bit hit and miss. Why? Well, for starters, companion planting is a northern hemisphere concept that works a treat up there, but not as well down here in Australia.
Secondly, it doesn’t work so well because it isn’t understood. We’ve all heard that basil and tomatoes should be planted together, but why? How many of each is required? Is one basil per tomato enough? Who benefits? What are we deterring? Does it enhance flavour? For years, I planted one basil plant next to each of my tomatoes, and guess what? Nothing happened. There was no discernable difference in taste. Nothing seemed to be encouraged or deterred. Nothing grew better or worse than it had before, there was simply no advantage, other than me not having to walk so far to make a pasta sauce!
Do you know why? Because, for basil to successfully repel flies from tomatoes, an absolute shovel-load of basil is required in your patch. I’m talking several basil plants for each tomato, and even then it won’t repel fruit fly. I love basil as much as the next gardener, but I don’t love it that much, and, to be honest, I’ve never had an issue with flies on my tomatoes. But who knew this? And how many of us think that this is the quick fix for all our garden woes?
Get Your Fix – Companions that Work!
By encouraging this assortment of good guys, my garden is almost completely without the bad guys, who never get a foothold in numbers that matter to me anyway! Remember, a lettuce leaf with a hole in it doesn’t require chemical warfare, nor does it signal an attack of the dreaded munchies! So now that I’ve put you off companion planting all together, let me say that I reckon there are some combinations that really work, especially those that involve plants that have a fair odour to them.
Well, companion planting CAN be the quick fix, and here’s how: biodiversity! The best thing about companion planting is that it increases the biodiversity of your patch; that is, the variety of life forms in your garden. Some of the greatest companion plants in my garden are those which have nothing to do with my vegetable patch, but are the awesome locally native trees and shrubs I have planted about the place. Clever planning (if I do say so myself) has meant that my garden is never without blossom, and is therefore never without the array of critters that come with that: birds, pollinating insects (like butterflies, bees, and native wasps), reptiles, beetles and all sorts of helpful garden buddies.
