Spacing and Competition

Correct plant spacing is essential for high yields and healthy plants. If plants are too close, they compete for light, water, and nutrients, and air circulation is reduced (increasing disease risk). If they are too far apart, you waste space and invite weeds to take over the bare soil.

Pro Tips

Layout Pattern: Triangular (hexagonal) spacing is the most efficient way to tile a space, allowing you to fit more plants with the same distance between them compared to a square grid.
Airflow: For plants prone to mildew (like zucchini or roses), always lean toward wider spacing to maximize airflow.
Mature Size: Always space plants based on their mature width, not their size at planting. It might look sparse now, but it will fill in!
Intercropping: If you have wide-spaced slow growers, you can plant fast-growing 'catch crops' like radishes or lettuce in the gaps while you wait.

Fun Facts

"Native Americans used the 'Three Sisters' method (Corn, Beans, Squash) to perfectly utilize vertical and horizontal spacing."
"Triangular spacing is how bees build honeycombs—it's nature's most efficient use of space."
"The area required for one plant in a triangular grid is about 86.6% of the area in a square grid."
