Vegetable Planting Schedule, Hardiness Zone Look-up, & Germination Temperature Chart (1)

If there’s one thing that every gardener learns, — timing is everything. The path to a healthy harvest always starts with basic foresight and planning. TheVegetable & Herb Timing tables below provide the basics for scheduling your conventional and vertical Garden Tower plantings. And don’t forget to check out the Seed Germination versus Temperature chart to make sure your plants stay on schedule!

Gardening with a high-volume container system like the Garden Tower® gives you a head start, literally. In a sunny location, soil in the Garden Tower will heat up faster (and retain a higher temperature) than in conventional gardens. If nighttime frost protection can be provided for (tarps, garden fleeces, bed sheets, large trash bag, etc.), the typical traditional planting schedule can often be moved forward an entire month.

Use the data below to learn both when to start your seeds and when to transplant outdoors.

FAQs

How to plan a vegetable garden layout? ›

As a general rule, put tall veggies toward the back of the bed, mid-sized ones in the middle, and smaller plants in the front or as a border. Consider adding pollinator plants to attract beneficial insects that can not only help you get a better harvest, but will also prey on garden pests.

What temperature can vegetable seedlings tolerate? ›

Colder temperatures (26-31 degrees F.) may burn foliage but will not kill broccoli, cabbage, cauliflower, chard, lettuce, mustard, onion, radish, and turnip. The real cold weather champs are beets, Brussels sprouts, carrots, collards, kale, parsley, and spinach.

Which zone is New Jersey in? ›

New Jersey is in USDA plant hardiness zones 6-7. Use your last and first frost dates below to calculate your planting schedule. *Based on statistics there is a 10% chance that frost will occur before or after these dates.

How to calculate when to start seeds indoors? ›

To determine the best time to start your seeds indoors, check the back of the seed packet to see how many weeks the seed needs to germinate and grow before it's transplanted. Using that number, count backward on the calendar from the average last frost date – that's May 15th in our area.

What vegetables should not be planted next to each other? ›

What is the best temperature for germination of vegetable seeds? ›

Many factors affect seed germination, but the most challenging for gardeners and often least understood is soil temperature. While there is can be variation from one seed type to the next, most seeds for warm-season edibles prefer soil temperature between 70 and 80 degrees Fahrenheit (21.1 and 26.7 Celsius).

What temperature do tomato plants tolerate? ›

Another temperature to keep in mind: tomato plants will not survive in temperatures below 35 degrees Fahrenheit, and will not thrive at temperatures below 50 degrees. Gardeners can use a frost date calendar to note their region's average dates of last frost in spring and first frost in fall.

What temperature can cucumbers tolerate? ›

Like all crops, cucumbers too have a preferred temperature range. As a warm season crop, the ideal temperature range for cucumbers is generally 21-26°C (70-80°F). However, the plants can withstand a wider range, if necessary, ranging from 15-29°C (60-85°F).

What is the best way to set up a vegetable garden? ›

Preparing a Vegetable Garden Site
  1. Choose a sunny spot. Most vegetables do best in full sun, over 8 hours of direct sunlight per day. ...
  2. Avoid low-lying areas. Plant roots need oxygen, and vegetables are particularly sensitive to being submerged. ...
  3. Avoid the perimeter of old houses. ...
  4. Consider convenience.

What is the most common garden layout for growing vegetables? ›

The most basic garden plan consists of a design with straight, long rows running north to south orientation. A north to south direction will ensure that the garden gets the best sun exposure and air circulation. A garden that runs east to west tends to get too shaded from the crops growing in the preceding row.

What is the best layout for garden rows? ›

Additionally, arrange the plants in such a way that the tallest ones are at the north end of the row, followed by medium-height veggies, and finally, the shortest ones at the south end. This arrangement maximizes sunlight exposure for all the plants.
