Companion Plant Spacing Calculator by Michael Bomford
Abstract
A popular recommendation for determining plant spacing in mixtures does not account for
component crop ratios and results in lower total plant density than separate plantings of
component crops in pure stands. This method likely compromises the yield advantage that
should be expected from mixed plantings. A new equation for calculating plant spacing in
mixtures is proposed. A spreadsheet and online spacing calculator, based on this equation, are
available for public use.

Background

Mixed planting, or companion planting, can offer benefits over monocultures:

o Mixed crops often have higher yields than monocultures because different species use
different resources, making more efficient use of land.1
o Mixed plantings often have fewer pest problems than monocultures because pests have
a harder time finding suitable hosts, or because diverse plantings provide better habitat
for natural enemies.2
o Diversity helps reduce risk. Promoting biodiversity is a stated goal of the USDA's
national organic standards.3

Some crops are commonly grown in mixtures. Hay, for example, is usually a mix of grass and
legume species. Shade-grown coffee plantations mix low-growing coffee bushes with trees.
Backyard gardeners often mix vegetables, herbs, and flowers in the same bed.

Although mixed plantings are common, practical resources for those who grow mixed crops are few;
production guides and extension materials are often based on the assumption of monoculture.

Biointensive mini-farming
One practical guide for gardeners and small-scale producers growing mixed plantings is the popular manual How to
Grow More Vegetables, by John Jeavons.4 It advocates a system called "biointensive mini-farming," which consists of
high-density mixed plantings grown in offset rows in carefully-prepared soil. Jeavons claims the system often yields
twice as much as conventional methods.

The book is distinguished by detailed tables and diagrams (unlike most books dealing with mixed plantings, which
tell you what to mix, but not how). Higher densities are achieved through tight plant spacing and elimination of space
between rows, so that every plant is the same distance from its six nearest neighbors, creating a beehive pattern of
hexagons:

Hexagonal spacing diagram from How to Grow More Vegetables... (Jeavons 2006). The spacing between plants
is equivalent within and between rows, forming a hexagonal lattice of tightly-spaced plants.

For plant spacing in mixtures, Jeavons uses the mean of his recommended plant spacings for the component crops.
For example, he suggests that corn plants in monoculture be spaced 15" apart, and beet plants 4" apart, so corn and
beet planted as a mixture are spaced 9.5" ([15+4]/2) apart:

Two-crop companion planting diagram from How to Grow More Vegetables... (Jeavons 2006).
The recommended spacings for corn (C) and beets (B) in monoculture are 15" and 4"
respectively. The book recommends a mean spacing of 9.5" when the two crops are mixed.

The bed illustrated in this example covers approximately 60 sq. ft. with 33 corn plants and 80 beet
plants. The plant density is 5 corn plants and 12 beet plants per sq. yd., for a total of 17 plants per sq.
yd.:

Two-crop companion planting diagram with dimensions, adapted from How to Grow More
Vegetables (Jeavons 2006). Corn plants are represented by yellow circles; beets are red.

A pure stand of 33 corn plants spaced according to Jeavons' recommendations requires 45 sq. ft. of
bed space, and a pure stand of 80 beets requires 8 square feet of bed space. Thus, the same number of
plants grown in two pure stands would require only 53 sq. ft. of bed space, leaving 7 sq. ft. for
another crop:

Pure stands of corn and beet plants, spaced according to How to Grow More
Vegetables(Jeavons 2006).

The mixed planting arrangement in Jeavons' example has three beet plants for every corn plant, but
more than five times as much land dedicated to corn as to beets. What if the land were evenly
divided between the two crops?

Dividing the 60 square-foot bed in half would give room for 22 corn plants on one side and 309 beet
plants on the other -- roughly 14 beets for every corn. To grow those same 331 plants in a mixture,
with 9.5" between plants, would require 180 sq. ft. -- three times as much land as the two pure stands
combined!

If crop mixtures make more efficient use of resources than monocultures then mixed plantings
should not require more land than pure stands. The example above suggests two problems with the
spacing recommendations from How to Grow More Vegetables:

o The area available to a plant is proportional to the square of plant spacing. (Plants
spaced 13" apart in a hexagonal lattice each have a square foot to grow, but plants
spaced 26" apart each get four square feet.) Calculating the mean area per plant offers a

better approximation of the resources available to each plant in a mixture than the mean
plant spacing used by Jeavons.
o The proportion of each crop in a mixture is crucial. Calculating the mean plant spacing
does not account for mixtures with different component crop proportions.

To address these problems, I propose the following equation to calculate plant spacing in a mixture:

where

o sA and sB are the recommended pure stand spacings for crops A and B, respectively, and
o p is the proportion of plants in the mixture (a value between 0 and 1) accounted for by
crop A .

In the example above, corn accounts for one-quarter of the plants in the mixture, so p=0.25. The
recommended spacings for corn and beets are 15" and 4", respectively, so sA=15 and sB=4. The
calculated mixture spacing, according to the equation, is 8.25" instead of 9.5".

In the case where corn accounts for only one-fifteenth of the plants in the mixture, p=1/15=0.067, so
the plant spacing is only 5.5".

A spacing calculator for mixed plantings
Since using this equation is more complex than calculating a mean, I have developed a new spacing
calculator for two-crop mixtures, available for download (Fig.4). A simpler online version, which
can be used for mixtures of up to four crops, is. Both calculate spacings for offset rows, based on the
geometry of hexagonal spacing arrangements and target crop ratios. The spreadsheet allows the user
to select two crops and target ratios from drop-down menus. Recommended plant spacings and
densities are calculated in metric and US measurement units.

This is a Microsoft Excel spreadsheet, created with Excel XP. It may not work with earlier versions
of Excel or other spreadsheets. The graphing feature requires the Analysis ToolPak Add-in for Excel
(check the Add-Ins feature under Excel's Tools menu if the graphs don't work), but the graphs aren't
necessary to calculate plant spacings.

Figure 4. A screenshot of the spacing calculator spreadsheet being used to calculate spacings
for a mixed planting of corn and beets.

Using the spacing calculator spreadsheet
Select your preferred options using the drop-down menus for the four yellow cells. The calculator
does the rest.

1. Select your preferred source for monoculture spacing recommendations. Three sources are built
in:

a. In-bed spacing recommendations from How to Grow More Vegetables...4

b. In-row spacing recommendations from Rodale's All-New Encyclopedia of Organic
Gardening.5

c. In-row spacing recommendations from 2006-07 Vegetable Production Guide for
Commercial Growers.6

The fourth option, labeled "Custom," is initially set to the mean of the other sources. Custom
values can be edited to reflect other recommendations or user preferences.

Where a range of recommendations was provided by a particular source the median value was
used.

2. Select two crops using the drop-down menus for the yellow cells. The first crop should be the
one that requires more space.
3. Select a target ratio for the second crop. The "Even ratio" column indicates the ratio that would
devote the same land area to each crop. For the corn/beet mixture in the example, 14.1 beets
require as much land as one corn plant. A target ratio of 15 beet plants for every corn plant is
the option that comes closest to an even corn/beet mix. Select a target ratio that approximates
your desired harvest.

grown in monoculture, is provided along with spacing for the mixture, in bold.
2. Row

spacing
3. Area The mean area dedicated to each plant.
4. Density The number of plants in a given area. This may be helpful for practitioners of Mel
Bartholomew's "square foot gardening" system.
5. Mixture The distance between plants of the same species in a mixture. For example, corn
spacing plants grown in a 1:15 corn:beet ratio will be spaced four times further apart than
beets (see Fig. 5B, right).
6. Mono. Measures of the relative amount of land needed to grow the plants used in a mixture
equiv. and in monocultures. For example, if the plants used for a 1:3 mixture of corn and beets
Mono. prop. were instead divided into two monocultures, the corn would fill 82% of the land, and
the beets would take the remaining 18%. The monoculture equivalent for beets would
be 0.18, and the monoculture proportions for corn and beets would be 82 and 18%,
respectively.

A spacing calculator for mixed plantings
This form calculates spacing for mixed plantings, based on pure stand spacing recommendations and
the ratio of crops in a mixture. Mixtures spaced according to its recommendations use the same
amount of land per plant as segregated pure stands, allowing a meaningful comparison of the land-
use efficiency of mixtures and pure stands. The theory behind the calculator is discussed in more
detail

Using the spacing calculator
1. Fill in standard spacing recommendations for up to four crops. The units (inches, centimeters,
feet etc.) must be the same for each crop; calculated values will use the same units. The default
values are spacings for corn and beet, in inches, from How to Grow More Vegetables (Jeavons
2006). Pure stands of corn and beets are shown in Figure 5A, spaced according to these
recommendations.
2. Fill in the ratio in which those crops will be planted in the mixture. The default ratio is one corn
plant for every three beets (1:3), illustrated in Figure 5B.
3. Click on the button labeled 'Calculate mixture spacing.'

Figure 5A. A square meter of corn (white circles, left) and beets (black diamonds, right), planted in
monocultures using the hexagonal spacings recommended in How to Grow More Vegetables... (Jeavons 2006).

Figure 5B. A square meter of corn and beets, grown in mixtures with corn:beet ratios of 1:3 (left), 1:8 (center),
and 1:15 (right) using plant spacings calculated by the spacing calculator. The space between corn plants is the
calculated 'clump spacing' value -- the distance between repitions of the planting pattern.

The calculator performs two calculations:
1. Plant spacing for evenly spaced mixtures.
This is the distance between plants in a mixture, assuming regular spacing between all plants. In the
default example, illustrated on the left of Figure 5B, all plants are 8.3" apart. In order for all crops to be
evenly spaced, the sum of the ratio components should be a perfect square. Examples of evenly spaced
two-crop mixture ratios are 1:3, 1:8, and 1:15, which add up to 4, 9 and 16, respectively (Figure
5B). Examples of evenly spaced three and four-crop mixture ratios are 1:2:6 and 1:3:6:6, which add up
to 9 and 16, respectively.

2. Clump spacing for clumped mixtures.
It is not necessary to have an evenly-spaced planting arrangement to use the spacing calculator. A
simpler method is to arrange crops in evenly spaced clusters, and use the spacing calculator to calculate
the distance between clusters. For example, a gardener who desires a 1:1 ratio of corn:bean
plants would use the 'clump spacing' value to space her corn, then plant a bean next to each corn plant.
If corn and beans are spaced 15" and 6" apart in monoculture, then each corn-bean pair would be 16"
apart in the mixture.

A more complex clumped mixture is a native American 'Three sisters' planting, featuring mounds of
corn and bean clusters between squash plants. A common crop ratio for a 'Three sisters' planting is
4:4:1 corn:bean:squash. The 'clump spacing' value recommends that mounds be spaced 36" apart if the
pure stand spacings of corn, bean and squash are 15", 6", and 18", respectively.

Companion Planting INCREASES Food Production by 250 Percent
One of the goals of research in South Africa is to look at ways to boost food production with the
practice of intercropping (companion planting, or growing crops together) a cereal grain crop, like
sorghum, with bean crops. We have been intercropping sorghum with legumes planted in row of zai
pits.

Why grow beans? Being legumes, bean crops can improve soils by converting nitrogen from the air
into forms that crops can use. The crops we are working with are quite tolerant of dry conditions and
produce vines that cover the ground, protect6ing it from the intense tropical sun and creating an
environments in which soil microorganisms, can thrive. Moreover, the legumes provide the farmer
with a harvest of dried, edible beans.

What are zai holes? The zai system originated in West Africa as a way to cope with drought and hard
encrusted soil. Drought tolerant grain crops such as sorghum or millet are planted in pits about 12
inches, 6 inches deep. With the excavated soil thrown to the downhill side, the pits act as tiny water
catchment basins, making maximum use of what little rainfall is received. Several handfuls of
manure are traditionally placed in each pit, concentrating nutrients near the crop roots.

Have we seen any benefits? The results we have so far are from year one of a sorghum-legumes
intercropping strategy within the zai system. Most of the legumes we have tried have grown very
well, but cowpea produced the most dried beans.

It increase total grain production from 400 kilograms per hectare when grown sorghum alone to
about 1400 kilograms per hectare when grown together with cowpeas.

It also increased soil nitrogen as well as nitrogen taken up by the sorghum plants.

All of this is very encouraging from the perspective of the smallholder farmer, because it means they
have a way to improve their soils while greatly increasing food production.

NATURAL SOLUTIONS in Africa by Using Companion Planting
Across East Africa, thousands of farmers are planting weeds in their maize fields (Companion
Planting). Bizarre as it sounds, their technique is actually raising yields by giving the insect pests
something else to chew on besides maize.

It is better than pesticides and a lot cheaper, said Ziadin Khan, whose idea it is.

And it has raised farm yields by 60-70 Percents.

In East Africa, maize fields face two major pests, and Khan has a solution to both. The first is an
insect called the stem borer. True to its name, it s larvae eat their way through a third of the regions'
maize most years.

But Khan discovered that the borer in even fonder of a local weed, napier grass. By planting napier
grass in their fields , farmers can lure the stem borers away from the maize and into a honey trap. For
the grass produces a sticky substance that traps and kills stem borer larvae.

~
The second major pest is Striga, a parasitic plant that wrecks 10 billion dollars worth damage on
maize crops every year, threating the livelihoods of one hundred million Africans.

Weeding Striga is one of the most time consuming activities for millions of African women farmers,
says Khan.

But he has an antidote: another weed, called Desmodium. It seems to release some sort of chemical
that Striga does not like. At any rate, where farmers plant Desmodium between rows of maize, Striga
will not grow.

Khan's cheap fixes for Striga and stem borer are spreading like wildfire through the fields of East
Africa.

Trials on more than 2,000 farms are finished. It is out of our hands now, says Khan's boss Hans
Herren , who is the director of the International Centre for Insect Physiology and Ecology in Nairobi.

The ideas are being taken up by framers in countries such as Ethiopia where we have never worked.

Khan's novel way of fighting pests is one of the host of Low-Tech Innovations boosting
production by 100 percent or more on millions of poor Thirds World farms in the past
decade.

This Sustainable Agriculture just happens to be the biggest movement in Third World Farming
today, dwarfing the tentative forays in genetic manipulation.

It seems peasant farmers have a long way to go before they exhaust the possibilities of traditional
agriculture
