Today we see so many new plant varieties, but that doesn’t always mean that older varieties are now ‘not worth growing’. That certainly isn’t true with the Jersey Blueberry, which is certainly an heirloom – it was created in 1916 – but certainly still very much worth growing. This larger bush, growing up to 8 feet tall, gives a yield of up to 10 pounds of delicious berries. Not only that, the Jersey Blueberry is incredibly valuable because, while most blueberries are ready in June or July, this one takes its time, and only starts to ripen in August. For the perfect crop of large, delicious blueberries with the true taste of wild bushes, nothing can beat it. With such a huge crop there will be plenty for baking, after the smoothies and berry breakfasts, and the rest of the crop can be put in the freezer – don’t even wash them – and pulled out for special occasions when the snow lies deep on the ground – what a treat!

Growing the Jersey Blueberry

Size and Appearance

The Jersey Blueberry is a deciduous shrub that will grow 5 to 8 feet tall, and up to 5 feet wide. The glossy leaves are about 2 inches long, and in fall they turn gorgeous shades of orange, earning this shrub a place in any garden bed. In spring, after the new leaves have grown a little, you will see clusters of small pink and white flowers hanging from the branches. These look like small urns, and they are a charming feature that again makes this an attractive bush for the back of a shrub border. Through the late spring and early summer those flowers become round green berries that ripen by the very end of July, or in August, depending on where you live. Over 2 or 3 weeks they gradually ripen into a deep blue, with that pronounced white ‘bloom’ on them, that makes blueberries look so special. They have the perfect balance between tart and sweet, excellent texture, and the wonderful taste of wild berries – wow!

Using the Jersey Blueberry in Your Garden

You can definitely grow this lovely bush right in your garden beds, or in a dedicated area for fruit production. It is self-pollinating, so just one bush will give you a good crop, but for the biggest harvest another variety is helpful. We recommend the Patriot Blueberry, and each will help the other give their biggest fruit and heaviest harvest. As well, the Patriot Blueberry ripens early, in June, so just as you are finishing the last of those from the fridge, you will be about to start on your Jersey Blueberry crop – the perfect pairing. Blueberry bushes are not fast-growing, but they are long-lived, and you can expect to be harvesting 20 years or more from now.

Hardiness

The Jersey Blueberry is hardy all the way from zone 4 to zone 7, covering most of the country, so there is an excellent chance that you can grow it successfully.

Sun Exposure and Soil Conditions

Plant your Jersey Blueberry bushes in full sun for the best results, but a little shade for a couple of hours a day won’t do any harm. The soil should be well-drained but moist, and most importantly, it should be acidic, with a pH value between 4.0 and 5.0. While it is possible, if your soil is already a little acidic, to lower it to that range, it is often difficult. The solution is easy – grow your bushes in boxes and pots. Blueberries have a small root system, so they live in pots for many years, and fruit very successfully. For the best results, make sure you have drainage holes, and plant in a mixture of 1-part lime-free potting soil, 1-part shredded pine bark, and 1-part sphagnum peat moss (the brown type sometimes called Canadian peat moss). Mulch the top of the pot with more shredded pine bark and stand it on a few stones, so that it drains freely.

Maintenance and Pruning

The secret to growing the Jersey Blueberry well is to use plenty of mulch, to conserve moisture and feed the bush. Any lime-free material is suitable, particularly, pine needles, oak leaves, shredded pine bark, peat moss of any kind, or softwood sawdust. Mulch in late spring, and again in fall. Water regularly during dry weather, as blueberries are not drought tolerant. Generally this bush is free of pests or diseases, but susceptible to rabbit attack. Pruning is not usually needed, at least until your bushes are older. To keep pot-grown plants outdoors all winter you should be in zones 6 or 7. In cooler zones it is best to keep plants in a cold shed or garage for the coldest months (light is not necessary) or bury the pot in the ground in fall, digging it up once the ground thaws.

History and Origin of the Jersey Blueberry

Elizabeth Coleman White was the daughter of a cranberry grower in South Jersey towards the end of the 19th century. She wanted to expand the crops of her family’s farm to blueberries, but at that time little was known about how to grow the bushes in her region, which were the highbush blueberry, Vaccinium corymbosum. In 1910 she stumbled upon some research into growing blueberries by Frederick Vernon Coville, the chief botanist at the US Department of Agriculture, and together they pioneered the growing of blueberries. At first they relied on propagating superior plants found in the wild by pickers, and two varieties, ‘Rubel’ and ‘Grover’ were discovered that way. In 1916 these two varieties were crossed together in an early experiment in controlled breeding, and the result was a bush released in 1928 by the USDA with the name ‘Jersey’. Today an heirloom variety, it is still popular and widely grown, even by commercial growers, because it extends the harvesting season by ripening late.
