Step-by-Step Method to Grow Zucchini from Kitchen Scarps

#1 Make your own seeds

  • Choose matured zucchini from the scraps, so that seeds can be easily germinated. Fruit with immature seeds will not germinate.
  • Scoop all the seeds using your hand or spoon.
  • Wash the seeds in water to remove any pulp and pat dry using a paper towel.
  • Place the seeds on window sill to dry the seeds under sunlight.
  • Turn the seeds after couple of days, so that moisture is completely dried.

How long does it take dry seeds?

If you washed the pulp thoroughly, it may take 3-4 days until it become dry and crisp.

Note: Don’t expect that every seed will germinate. Depending on soil, climate and other conditions germination ratio will be 70-80 percent (20-30 percent of seeds may fail to germinate).

#2 Choosing a Container

Most gardeners prefer to germinating seeds in a tray with coconut coir or potting mix. After seedlings appear and reach at least 3 inches of height, then they are transplanted to other containers.

If you’re just starting your gardening journey, then I don’t recommend this method; because minor mistake can kill your plant.

Choose a container and grow the zucchini plant in it.
