How to Grow Zucchini From Seeds


Zucchini is a warm-season vegetable and a variety of summer squash. Easily grown all over the country throughout the warm season makes it a popular choice for many home gardens. It only requires a couple strong and well cared for zucchini plants to generate lots of tasty treats and enough for an entire family. Zucchini grows best from seeds sowed directly in your garden after the soil has warmed to at least 70 degrees F at a depth of 2 inches.

Step 1

Pick a time to plant your zucchini seeds after the danger of freeze passes. Choose a planting date from the beginning of spring up to the middle of summer.

Step 2

Select a location that has plenty of sun throughout the day. Figure enough room to allow for 2-3 feet of space all around each zucchini plant.

Step 3

Use a rake, hoe and/or shovel to clear the area of roots, rocks or other debris. Add compost and/or well-rotted manure with a shovel. Mix this into the soil with a rototiller or hand garden tool to a depth of 6-10 inches.

Step 4

Place a few seeds ½ to 1 inch deep, 2-3 feet apart in a row. Or create hills of soil, plant five seeds in each and leave 4 feet of space between hills.

Step 5

Thin out the stronger plants when seedlings are 2-3 inches tall. Leave one zucchini plant every 2 feet for rows planted or no more than three for each hill planted.

Step 6

Supply at least 1 inch of water per week throughout the growing season when rainfall is inadequate. Use a shovel to add 2 inches of mulch around zucchini plant to retain moisture and prevent weeds, if desired.

Step 7

Hand pull any weeds emerging around the zucchini plants. Harvest zucchini at any size you like and before fruits become too big.
