History of the Jersey Blueberry

The Jersey Blueberry, also known as Vaccinium corymbosum, is one of the oldest blueberries in the U.S. It was invented in 1916 by a group of breeders in New Jersey and released to the public in 1928. Jersey is often thought of as one of the gold standards of blueberry shrubs, and modern plants are often compared to it.

Characteristics of the Jersey Blueberry

Jersey is a northern highbush variety blueberry shrub and one of the tallest of its kind. It typically produces a high yield of large, juicy blueberries. Jersey is a vigorous, erect, and hardy bush that’s adaptive to whatever area you choose to grow it in. It’s noteworthy for being one of the best plants to grow in northern climates where the weather is harsher.

Chill Hours

The Jersey Blueberry requires a chill time of 800 to 1000 hours.

Ripening Season

The ripening season for Jersey blueberries is usually mid to late summer, with August being the typical month of ripening.

Blueberry qualities

Jersey blueberries are on the sweet side and turn blue to light blue when they’re ripe for the picking. These blueberries are also firm and plump in texture and will produce a nice crunch when you bite into a ripe one.

Blueberry size

Jersey Blueberry shrubs offer berries that are medium to large. As your plant matures, it will produce berries of increasing sizes.

Planting Zones

You should plant Jersey Blueberries in hardiness zones 4-7. Hardiness zones refer to the minimum temperature typical of a climate. Jersey Blueberries are hardy plants but won’t survive frost or freezing temperatures.

Size and Spacing

Jersey Blueberry shrubs aren’t just renowned for the quality of their berries but also for the size and quality of the bush itself. It’s one of the tallest blueberry shrubs and can grow up to heights of 6-10 feet at full maturity. Jersey also spreads wide and can be between 5 and 6 feet wide.

To give your plants the best chance of success, you should plant them at least 5 to 6 feet apart. Like I just said, Jersey Blueberry shrubs grow wide and tall, and you don’t want to cramp them into a small space.

Pollination

The Jersey Blueberry is a self-pollinating variety and doesn’t require cross-pollination for successful growth. However, cross-pollinating with the Elliot, Darrow, or Sweetheart blueberry will produce the best results for the Jersey and whatever plant you cross with it. Whichever plant you choose should be planted within 50′ of your Jersey Blueberry shrub.

Blueberry Shrub Care

Jersey Blueberries are hardy and vigorous, and cross-pollination improves their yield. However, the only way to ensure the success of your shrub is to care for it properly. Here’s what you need to know about blueberry shrub care.

Sunlight

Like most blueberry plants, Jersey should get a minimum of six hours of sunlight per day. The preference is that they get full sun, but partial shade will do as well. However, you should also consider your climate. Jersey can withstand temperatures of up to 85 degrees, so make sure your shrub gets light shade if this is the typical temperature in your area.

Soil

Soil should be acidic and well-drained with a pH level between 4.5 and 5.5. You should have your soil tested to determine the acidity levels and add or remove from it accordingly. The best way to increase acidity is to elemental sulfur in the form of compost.

Water

Blueberry shrubs require constant moisture but without flooding. However, in times of drought, Jersey Blueberries will still produce fruit if they’re under-watered. They simply won’t be as productive.

Fertilizer

For maximum results, you can add mulching with a mixture of pine straw and pine bark. This will help drain the soil your shrub is planted in and help your plant grow. Fertilizing should be done in the spring with a well-balanced, slow-release fertilizer.

Pruning

For pruning purposes, you should start by removing small spindly branches that are unproductive. As your plant continues to grow, only prune branches that block sunlight and impede your plant’s growth. In winter, you should also prune your shrub to remove any dead, dying, or crowded branches.
