Introduction
Within the introduction to this e-book, Jessica Walliser will get us ready for the place we’ll be touring together with her – on a path that veers away from conventional companion planting lore.
Why this break? Conventional pairings are sometimes repeated however not at all times verified. As an alternative, Walliser might be introducing us to partnerships that stand as much as scientific scrutiny.

This scientific method has a number of advantages – it permits us to make use of confirmed combos in our personal gardening endeavors, but in addition to know the why and the way of profitable combos, enabling us to make our personal companion groupings.
Along with setting us up for a scientific method to the topic, Walliser’s introduction encourages us to see our personal yard landscapes as ecosystems, the place crops have completely different relationships to one another.
The Energy of Plant Partnerships
The primary chapter expands on the introduction, heralding a contemporary method to companion planting in addition to a motion away from monoculture gardening – the kind of agriculture the place one may discover a complete discipline of soybeans, or a strong row of watermelons.
The writer describes the forms of analysis which have been performed on this space – and why this analysis is related to these rising their very own meals at house.
Encouraging us to see our gardens in a unique mild, the writer mentions that mycorrhizae are at work not simply in forests however in our edible landscaping too, and explains that allelopathy, usually cited as a gardener’s downside, can be utilized to our profit.

Walliser reminds us that range needs to be a purpose in our gardens, stating that these created landscapes play necessary roles for offering small creatures with habitat as their pure habitat is misplaced to improvement.
She additionally encourages us to see that crops usually are not passive inhabitants of our edible landscapes, however are as a substitute actively affecting one another via numerous means: chemical messaging, fungal associations, and allelopathy, in addition to sharing sources, attracting pest predators, and enhancing nutrient availability and absorption.
Walliser lets us know that it’s these completely different results we’ll be exploring in the remainder of the e-book, with every remaining chapter showcasing a unique good thing about companion planting.
Soil Preparation and Conditioning
Chapter two takes a take a look at how companion partnerships can enhance soil by way of cowl cropping, nitrogen switch, and the breaking apart of heavy soils.
Coming again to the fascinating topic of mycorrhizae, the writer discusses the position of fungal networks in backyard soil and the way these networks perform for annuals.
On a really sensible stage, we discover ways to greatest use oats, cowpeas, buckwheat, crimson clover, winter wheat, and winter rye to our benefit in a house backyard. We additionally be taught the professionals and cons of turning these crops beneath versus leaving them for mulch.

It’s possible you’ll be properly conscious of the nitrogen-fixing talents of legumes, however have you learnt which legume crops are the most effective at doing this job? I didn’t – till I learn this chapter!
Walliser offers 5 examples of profitable legume and vegetable crop combos. One in every of my favorites I discovered right here was cowpeas and peppers, which I’ll be attempting out in my very own summer time backyard.
And for growers involved with heavy or compacted soils, we additionally be taught which crops have roots which are good at drilling into the sort of earth.
One in every of these was a shock to me – buckwheat. This annual is often used as a canopy crop or inexperienced manure, however I wasn’t conscious that additionally it is capable of enhance soil construction via its root exudates.
Weed Administration
Chapter three focuses on managing weeds via using dwelling mulches and allelopathic companions.
Not like cowl crops that are typically grown earlier than the principle crop, dwelling mulches are grown with crops on the identical time to cowl and shield the soil.
Walliser explains the best way to efficiently use dwelling mulches with out letting them get in the best way of your essential crop.
Among the many examples supplied for dwelling mulches are a number of several types of clover, every used with a unique harvestable crop.

And this chapter additionally provides us a take a look at utilizing allelopathic species to regulate weeds – maybe one of many least-known makes use of of companion partnerships in fashionable gardening lore.
I’ve to say, this part cleared up a giant, darkish cloud of confusion that has been hanging over my head as to why some species are allelopathic in some instances however not in others.
Not stopping on the merely theoretical, Walliser explains when an allelopathic associate might be protecting, and by which instances it may be counterproductive – and offers examples that may simply be tried out within the house panorama.
Assist and Construction
Chapter 4 proposes artistic choices for crops that can be utilized as dwelling trellises for different crops.
You’ve heard, little question, of the standard three sisters crop grouping – corn, pole beans, and squash?
Utilizing corn as a assist for pole beans is among the mostly cited companion partnerships and is a main instance of a dwelling trellis.

Walliser offers sensible recommendation for making such combos work in our gardens, with 11 extra dwelling trellis combos to strive.
One in every of these I’m excited to strive in my very own edible panorama is utilizing my Jerusalem artichoke patch as a trellis for tiny cucamelons, or mouse melons as they’re generally known as.
Pest Administration
In chapter 5, we find out about 4 completely different ways in which companion groupings might help with pest administration: luring, trapping, tricking, and deterring.
Earlier than we get into specifics, Walliser provides us a reminder of how pests discover their goal species within the first place, and clears up the distinction between repelling versus masking.

First, we discover lure cropping, a method the place a veggie crop is spared pest infestation by luring pests to an much more fascinating one.
One instance she cites is utilizing the ‘Blue Hubbard’ winter squash to draw pests away from different types of squash.
Together with offering helpful recommendations on the best way to distance a lure crop from a harvestable crop and what to do with an infested lure crop after getting one, the writer offers steerage for several types of pests – ones which are “extremely cellular,” akin to squash bugs, and ones that aren’t, akin to flea beetles.
Additionally mentioned on this chapter are masking methods – methods to “disguise” crops from pests.
One of many combos the writer suggests is the basic companion combo (and Italian meals pairing par excellence) of tomatoes and basil, by which the herb protects the nightshade veggie from thrips.
Interfering with egg laying is the following subject we encounter on this chapter, the place we be taught that companion planting might help to throw a wrench into the reproductive plans of pests. Walliser offers us with six confirmed combos for this technique.
Lastly, this chapter affords options for impeding pest actions. One in every of these is actually an ode to the hedgerow, which I discover in and of itself to be worthy of the value of the e-book.
Illness Administration
Chapter six examines the prospect of managing soilborne illnesses utilizing cowl crops and dwelling mulches.
One won’t think about illness administration to be an apparent good thing about companion partnerships. You might have heard, as an illustration, that furry vetch makes a superb cowl crop. However do you know it’d shield your tomatoes from sure illnesses?

In “Plant Companions,” Walliser affords proof of this idea via six completely different combos which have been demonstrated to achieve success in analysis circumstances, and might be recreated within the house backyard.
Organic Management
Chapter seven focuses on organic management – that’s to say, protecting pest populations in verify by attracting pest-eating, useful bugs.
My first thought when digging into this chapter was, how is that this completely different from pest administration?
The reply is – it’s not. It’s half of pest administration.
Nevertheless, chapter 5 (the one titled “Pest Administration”) focuses on how crops themselves can be utilized to redirect pests, whereas this chapter appears at controlling pests with the assistance of useful bugs and spiders.

On this chapter, we discover ways to entice these backyard helpers in addition to the best way to create habitat for them.
That is clearly a topic pricey to the writer’s coronary heart, as demonstrated in certainly one of her different books, “Attracting Useful Bugs to Your Backyard: A Pure Method to Pest Management,” which can also be accessible on Amazon.
Attracting Useful Bugs to Your Backyard: A Pure Method to Pest Management
On the subject of attracting useful bugs, we find out about a number of particular combos that can assist management aphid populations, in addition to pairing suggestions for controlling different pests.
This chapter additionally affords strategies for creating habitat for useful bugs, since habitat and forage aren’t at all times discovered concurrently among the many identical species.
Walliser affords options for numerous forms of insect habitat, from low-growing floor covers to extra considerably landscaped hedgerows.
In case you’ve heard it’s a good suggestion to depart the lifeless progress of your backyard annuals over winter as insect habitat, you may surprise when it’s protected – in your bug buddies – to take away this lifeless materials. Walliser has a solution to this query.
This chapter additionally consists of a superb dialogue of the deserves of buying useful bugs for launch versus specializing in attracting native populations of the identical bugs.
And if you happen to haven’t but gotten the message that the guideline of companion planting is about creating a various panorama, you’ll get it on this chapter.
Pollination
The eighth and last chapter of Walliser’s e-book is about pollination.
In case you didn’t consider pollination as being one of many targets of companion partnerships, think about this: A lot of our crops rely upon the efforts of pollinators with a purpose to produce harvests, in any case – and companion companions can herald droves of pollinators.

Whereas the honeybee will be the poster baby for the “save the pollinator” motion, Walliser shines a light-weight on the various native pollinators which are at work in our gardens, and factors out they don’t are inclined to get the credit score they deserve.
The primary a part of the chapter affords 5 companion pairings to draw pollinators, whereas the second half offers recommendation on creating nesting habitat for pollinators.
One of many highlights of this chapter for me was the writer’s description of squash bees, which each forage from and curl as much as sleep in squash blossoms.
I’ll be heading out to my squash patch at evening this summer time to peek into the blossoms and verify for these reposing native bees!
Last Ideas
Digging deeply into this e-book as I’ve performed, I’ve come away a particular fan.
The content material introduced right here is properly researched and properly introduced, and Walliser’s language is each informative and fascinating.
I saved my typo radar on whereas studying and solely got here throughout a handful of minor errors – the e-book is each extraordinarily well-written and well-edited.
Nevertheless, that’s to not say I don’t have any criticisms to supply.
One in every of my quibbles is with the index. I searched the index for a few particular topics – marigolds and eggplant – and located that it got here up brief.
Eggplant is listed within the index as showing on pages 57, 152, and 153, however whereas additionally it is featured on pages 170 and 171 beneath the subject of rising giant or hooded flowers to draw bumblebees for improved pollination, these references have been omitted from the index.
As for marigolds, they’re showcased within the “Pest Administration” chapter as a superb companion to make use of with onion and cole crops. But poor little marigold was ignored of the index altogether.
However maybe I’m a little bit of a stickler on this level – I recognize a well-packed index.
My solely different grievance with this e-book lies within the printing medium, particularly the paper selection.
With Walliser’s encouragement to create habitat for small creatures as a substitute for dwindling pure habitat, the writer – and the writer, for that matter – appear to have a powerful dedication to environmental safety.
I’d have hoped that their dedication would prolong to picking recycled paper to print the e-book on, however alas, that seems to not be the case.
Once more, that is one other level the place I’m a stickler. I can solely hope when the second version of the e-book is launched (as I heartily count on it sooner or later might be!) that recycled paper might be thought of as an choice that’s extra in step with the underlying ideas championed within the publication.
It’s, in fact, accessible in digital format as properly, and the Kindle version could also be bought on Amazon.
Placing these two points apart, maybe you’re questioning who may profit probably the most from studying this e-book?
“Plant Companions” is beneficial for newbies to companion planting in addition to well-seasoned polyculturists. These of us who’ve been utilizing conventional companion pairings for many years could have many alternatives to broaden our data with Walliser’s e-book.
This publication might be learn from cowl to cowl as an enchanting e-book in regards to the concepts behind companion partnerships. And it will also be used as a extremely sensible reference e-book, illustrating dozens of particular partnerships that may remedy particular backyard issues.

As for myself, this publication has earned a spot on my shelf with my different important gardening references – and I eagerly await future works from the identical writer.
