When deciding on which plant to grow, it is crucial to know the climatic factors and the correct growing zone for the plant. New Jersey has an extensive area, and the climate varies significantly from the northern parts of the state to the southern regions. It ranges from hot to cold depending on which part of the state you are in.
Like other areas in the US, NJ has planting and growing zones that the US Department of Agriculture (USDA) has mapped out). Some plants will not grow and thrive in certain areas because of different climatic factors. This piece will highlight the important bits you should understand about NJ growing zones to help you make better planting decisions.
What Are Planting And Growing Zones?
The USDA uses a planting zone (hardiness zone) to categorize different country sections according to weather pattern data. There are 13 planting zones across the US, each separated by a 10-degree range. Gardeners use the Plant Hardiness Zones to select plants based on their ability to withstand certain temperatures and conditions.
The Planting And Growing Zones in New Jersey
New Jersey has a wide variety of microclimates. The state is both a border state and a coastal state. In New Jersey, there are four different planting zones: 6a, 6b, 7a, and 7b.To be successful in gardening or farming, you need to know your zone and its influence on your planting activities.
This means a lot of different factors can come into play when it comes to growing a plant. There is also a considerable difference in terms of the amount of rainfall each zone receives. To understand the zones better, let us have a look at each of them.
NJ Hardiness Zone 6
The area map for Zone 6 consists of two sections. Zone 6a has an average winter temperature of around 0 to -10 Fahrenheit. In comparison, Zone 6b has an average winter temperature of approximately 5 to -5 Fahrenheit. Both sections have plants that can grow in the corresponding zone. This is the coldest area where the plant is likely to survive.
Gardening in this zone can be advantageous because so many plants do well there. Here, you have the option of starting your seeds indoors in March and April, but you should transplant them outside at the end of May or the beginning of June. The warm season will last until November, giving you plenty of time to enjoy your garden.
Plants That Survive In Zone 6
Zone 6 is an excellent place to grow vegetables because the growing season is very long. The last frost date is at the beginning of May, and the first frost date is in early November. These dates vary a little, so it is essential to watch the weather before planting. The minimum temperature for zone 6 is -5ºF annually. Below is a list of vegetables that survive in zone 6.
Some of the shrubs that do well in Zone 6 are;
- Butterfly bush
- Rose of Sharon
Perennials that thrive in Zone 6
- Coral bells
- Bee balm
Farmers’ Tips for growing in Zone 6
- Planting an appropriate plant is very important for your region. The hardiness zone guide can help you decide what plants grow best in your area. Your choices include vegetables, fruit and nut trees, and trees and plants that grow in Zone 6.
- A lot of plants thrive in the garden, but some are not as easy to grow. For these plants, it is best to start with seeds indoors. Consider planting the seeds six weeks before the last frost date or whenever winter ends. Some of these plants are tomatoes, eggplants, pepper, and other plants, which are easily transplanted.
- Vegetable gardening is a popular activity among US households, with 31.9 million of them participating in it. You can directly plant vegetables, such as beans, cabbage, corn, cucumber, and squash from the beginning of May.
- The time it takes for a seed to grow into a vegetable is called the maturation time. For instance, lettuce seeds take about eight weeks to mature. When planting, always check the maturation days on the seed packet for the vegetable you want to grow. Doing that will guide you on your planting and expected harvest time.
NJ Hardiness Zone 7
Plants growing in Zone 7 have a more extended season than those in Zone 6 and at an average lowest temperature of 10 degrees higher. As you move into the next zone, the average lowest temperature in that particular zone increases by 10 degrees. There are also many trees, flowers, and vegetables that grow during New Jersey’s winter. Certain varieties of citrus trees also grow in Zone 7.
The first frost in this zone appears around mid-November, with the last one coming in the middle of April. With such a timeline, your plants have enough time to grow to maturity.
Plants that survive in Zone 7
You can start seeds indoors before the first frost in zone 7. This gives you a few extra weeks to grow vegetables, like broccoli and carrots. For a more extended season, you can plant once in spring and again in late summer. In NJ, there are a few different varieties of plants to grow during the winter. Here are a few trees, shrubs, flowers, and vegetables that you can grow in Zone 7.

As long as you watch out for the last frost date, April 15th, you can plant your flowers.
- April is the perfect month to get packets of annual seeds. You can also plant flower seedlings that have been grown indoors. This way, you extend the blooming season.
- Despite the misconception, citrus trees can be grown in this zone. The trifoliate orange is the superior choice for cold hardiness. However, sour oranges, Cleopatra mandarins, and citrus crosses also do well here. Mandarin oranges include mandarins, satsumas, tangerines, and hybrids thereof. They are all sweet citrus that peels easily.
