Guilds are more or less just a step beyond well-established companion
planting arrangements, moving from useful pairings onto functionally,
ideally self-sustaining polyculture systems. In guilds, many plants are
serving one another en route to a stable co-existence in which the
garden is mulched, the soil fertilized, the pests controlled, the
pollinators attracted, the nutrients accumulated and the cultivators
feed.
Basically, to guild a classic combo like carrots and onion, we’ll look
at what else we might supply for this mutually beneficial relationship,
as well as what’s missing. In this case,
both carrots and onions like to
grow along side lettuces, which could supply a great ground cover to
the mix, which would help keep the soil moist and the soil life safe and
provide a steady harvest in the meantime.
Peas work really well with
carrots but not so favorably with the onion family, so v
ining peas could
be trellised near carrots but separated from onions for nitrogen-fixing
and to add a vertical element to the combination.
Rosemary is a great
perennial herb that helps deter pests and could act as another taller
element in the mix, perhaps the centerpiece. Now we’ve got a pest
deterring upper layer, root crops, edible ground covers, and
nitrogen-fixing vines to provide shade for the lettuce. We’ve added a
lot more diversity with a lot of function.
Corn, beans, and squash are the classic example, and while these three
work great together and could be considered a guild as is, we might be
able to improve it. Corn is already providing a stalk for the beans to
climb, beans are provided nitrogen to feed the others, and the big
leaves of clambering squash plants are creating a moisture-retaining
ground cover.
In this combination, comfrey might be another great
addition, adding a deep-rooting nutrient accumulator, an attractant for
pollinators, and chop-and-drop mulch.
Sunflowers might work well as
productive deterrents to pest, sources of nutrient-rich seeds to eat,
but their allelopathic characteristics don’t mix well with beans (so be
aware). Amaranth might work better. Traditionally, the three sisters
would often also be accompanied by
chilis, sweet potatoes and more
Creating garden guilds just takes a little guile. Do some research.
Find out what likely makes good companions. From there, start
considering the characteristics of the individual plants and how they
might interact. Use this checklist to help you consider what’s going on:
•
Compatible water needs: If everything likes water, no worries. If
everything is drought-tolerant, wonderful. Start mixing it up and that
might be a problem.
• Different root systems: Try to vary root systems such that plants
aren’t competing, and try to think about
including a root crop in the
mix. Carrots also work well with tomatoes.
• Plant arrangement: Piece together plants of different sizes and
shapes, envisioning how they might work in close proximity.
What’s that
vine going to grow up? Stuff like that. Think of the vertical spacing.
• Insects, good and bad: Plants for attracting beneficial insects and
deterring pest need to be in the mix. Often, as in the case above, many
additions are performing this function.
• The soil: Something needs to always be covering it. Something needs
to always be feeding it new nutrients. Get a ground cover. Get
something to chop and drop. Hopefully, a nitrogen-fixer is in the cards.
• Use the rule of three: Have at least three reasons for including a
plant in the mix.
It attracts bees, provides food, accumulates trace minerals in the soil,
