Getting your plants in the ground at the right time is critical for the best harvest. There are a vast number of different vegetables to grow, so that's why it's important to check the planting dates, beginning with these, for the most common vegetables in gardens.
Onions can be planted 2 to 4 weeks before the last spring frost. They can grow in 40 degrees F weather temperature. Plant these 4 to 6 inches apart and at a depth of 1/4 inch.
Potatoes can be planted 2 weeks before the last spring frost. They are able to grow in temperatures around 40 to 50 degrees F. Plant them 12 to 15 inches apart and at a depth of 4 to 6 inches.
Corn can be planted at the last spring frost. They can grow in temperatures above 60 degrees F. Plant them 12 to 30 inches apart and at a depth of 1 to 1 1/2 inches.
Winter squash should be planted when there is no chill to the air and temperatures are always above 55 degrees F. Typically this is around 2 weeks or more after the last spring frost.
When the weather gets above 55 degrees F and stays without chill to it, plant tomatoes. It is generally 2 weeks or more past the date of the last spring frost before the ground is ready. Plant 24 inches apart and on a trellis.
Plant the cucumbers at near the last spring frost date. Temperatures over 60 degrees F are optimal. Plant these 24 to 36 inches apart and at a depth of 1 inch.
Plant the carrots around 2 weeks before the final spring frost. They can take temperatures 40 to 50 degrees F. Plant 2 to 3 inches apart and at a depth of 1/4 inch.
