Propagating Red Kuri Squash

With cuttings, plants may produce fruit earlier than those grown from seeds, so here are the perfect tips for propagating Red Kuri squash.

  • Take stem cuttings from your Red Kuri squash so you can make a new plant.
  • Cuttings should contain between 1–3 nodes, taken from the upper part of a stem with small leaves.
  • Plant them in well-drained soil-less media for faster growth.
  • Adding nodes along the stem of an established plant will encourage it to grow, as new roots will grow from those points.
  • Therefore, if one section of the stem is damaged, it can keep growing without any problem.

That was all about how to grow Red Kuri squash. Now, let’s see how you can care for the plant.

  • Add fertilizer regularly to provide enough nutrients to your seedlings.
  • Watering the ground—not watering the leaves or the fruits—is best for this crop.
  • Keep weeds down, and don’t let plants dry out. Plenty of water is required when plants are in flower or fruiting. You can add mulch to conserve water better.
  • The great companions to grow alongside Red Kuri squash include marigolds, radishes, beans, Calendula Officinalis, nasturtiums, and corn.
  • Moreover, consider planting flowers with your squash plants to give them better pollination rates by attracting bees.
  • Use row covers or insecticidal soaps to treat pests or disease infestation.

  • Red Kuri squash needs 80 to 95 days to ripe. You will know it is ripe when its skin color turns dark green to orange or red.
  • Harvesting should be done with care so as not to damage the squash and its roots, leading to rotting and disease. We recommend using a sharp sterilized knife or pruning shears.

  • Allow the squash to remain in the sunshine for about ten days before storing them.
  • Place harvested squash in plastic bags before putting them into your refrigerator.
  • Store them in a cool, dark environment with less than 65% humidity. It will help your squashes last for several months.
  • You can also keep Red Kuri squash for almost a year in a dry room with temperatures ranging from around 10 to 15°C.
  • It is best to cut any remaining leaves and stems from the fruit after harvest as they often bear diseases.
