In the world of gardening, efficiency doesn't always mean complexity.
Proof of this is with the ancestral concept of the three sisters, a cultivation method which combines simplicity and productivity.
This is plant synergy in all its splendor, a strategy that maximizes yield while minimizing effort.
What are the three sisters?
Imagine a perfect collaboration between three plants in your garden:
corn, squash and beans.
The corn rises and offers its robust stems as natural tutors for the climbing beans.
Squash spreads its broad leaves over the ground, forming a protective mat that retains moisture and prevents weeds from growing.
As for the beans, they play a key role in this association: they capture nitrogen from the air and enrich it in the soil, thus benefiting the other two “sisters”.
Together, they create a micro-ecosystem where each contributes to the health and vigor of the others, making
this polyculture technique
incredibly effective.

How to cultivate the three sisters?
To get started, start by planting the corn.
Once the stems have reached a certain height and are quite sturdy, plant the beans at their base.
They will climb along the corn stalks without smothering it.
Finally, sow the pumpkin seeds around it, making sure to
space the plants far enough apart
to allow their large leaves to develop.
This arrangement allows each plant to have the space and resources to thrive without hindering the others.
When to plant the three sisters?
Timing is crucial for the Three Sisters Technique.
Typically, corn is planted in early summer, when the risk of frost has passed and the soil is well warmed.
About two weeks later, when the corn has grown a few inches, the beans can be planted.
Squash, with its rapid growth and dense foliage, is added soon after,
completing the trio.
It is important to respect this chronology to allow each plant to settle in and play its role in this plant association.
