6. Thin Your Zucchini Seedlings
When your zucchini seeds germinate, thin them. In thinning your zucchini, just leave the two largest seedlings intact then cut the smaller ones. As your zucchini seedling continues to grow, check them. The weakest seedlings should be removed until the strongest seedling is the only one left in the container. Never pull the seedlings. Use knife or scissors to remove the weak seedlings from your container.
With proper care, your zucchini will be ready for harvest in no time. Enjoy planting!
