How to Grow Zucchini in Graniteville, Sc, United States of America

Zucchini is a summer squash, also called courgette and marrow, with each name representing a different stage of growth. Zucchini is derived from the Italian word 'zuchinno'. Zucchini belongs to the cucurbita family along with pumpkins and other squashes. Summer squash is believed to have originated in Central America and the zucchini developed in Italy many generations later following the European colonization of the Americas around the 19th century. Zucchini is a popular favorite with home gardeners because it is easy to grow and because of its high yields.

Zucchini Germination Guide

(Stage 1: Germination)

Germination is the process by which a plant grows from a seed. It is the first stage of the plant growing process and it begins when the seed is sown and ends when the radicale emerges out of the seed.

All seeds require proper soil temperature, moisture, air and light conditions to germinate successfully. However, during the germination stage the seeds require more soil warmth and moisture than light exposure.

Seeds respire just like any other living organism, requiring oxygen and producing carbon dioxide (CO2), so it is crucial to use a soil media that is sufficiently aerated so that the seeds do not “suffocate”.

70% of our growing experts recommend to directly sow zucchini seeds into the ground. What is direct sowing and why do I care about it?

Zucchini Growing Guide

(Stages 2-5: Growth)

Once seed has germinated and radicale has emerged the second stage of the plant growing process begins, developing from radicale to cotyledon -the embryonic first leaves of the seed forming a young seedling.

During the third stage of plant development cotyledon develops to 3-4 true leaves, stem begins to grow, becoming a mature seedling.

In the fourth stage the mature seedling develops to a young plant, ready for transplanting.

The fifth stage of plant development the plant is fully mature bearing fruit and/or flower.

The following guidelines apply to all of the zucchini plants’ needs during stages 2-5 from radicale emergence to full maturity. During these stages sunlight becomes a more active participant in plant growth and development than in the germination phase.

Soil pH is an important factor during these stages as well. What is pH and why is it important?
