Three Sisters Mix

Product Details

Corn, beans, and squash have been grown together for centuries in the Americas, and for good reason: they naturally work in concert with each other. Corn provides a growing support for the beans, which in turn provide nitrogen for the corn and squash. The large leaves of the squash provides shade that help to conserve moisture in the soil and control weeds. The seeds of each type of vegetable can also be saved from year to year, provided they are isolated from cross-pollination.

All three plants are heat lovers, so wait until the soil has warmed up in late spring when the soil is consistently 18°C (65°F) to direct sow. Start by planting the corn seeds 30cm (12") apart in as close to a grid shape as possible. Sow the bean seeds outside the perimeter of this grid. Sow the squash seeds at the corners of the grid so they are also 30cm (12") from the nearest corn seed.

Alternatively, start all the seeds indoors 3-4 weeks before planting out, and aim for the same kind of spacing. It may look sparse at first, but these are fast growing plants. They are all heavy feeders, so they do best in rich soil amended with organic fertilizer.

The Three Sisters are heat lovers, so wait until the soil has warmed up in late spring when the soil is consistently 18°C (65°F) to direct sow. If the soil is not warm enough, seeds may rot before sprouting. Warmer soil improves germination. If spring weather is cold, plant indoors with bottom heat, and transplanting once weather warms. Seeds should germinate in 7-14 days. Alternatively, start all the seeds indoors 3-4 weeks before planting out.

Step 5

Harvest

Bean: Beans can be picked as green beans when plump, and are tender and tasty when small. Beans can be dried but make sure to dry beans are cooked thoroughly.

Corn: When the silks at the end of an ear are a dry brown, the cob seems to start to droop, and the kernels release milky juice when cut.

Squash:  Fruit is ripe if your thumbnail doesn’t mark the skin and the stem is dry and brown. Cut the stem about 4cm (2″) from the fruit. Squash can survive a light frost, but store better if harvested before frost.
