Quick read / the essentials on Earliblue blueberry
Among the blueberry varieties most prized for their precocity, Earliblue stands out for its harvest as early as June, remarkable fruit stability, and attractive presentation on stalls. This old variety, developed in the United States in 1936, is now highly valued by market gardeners looking for firm, juicy, and good-sized fruits for fresh sale or short supply chains. The berries measure on average 15 to 18 mm and have a balanced taste, between sweetness and slight acidity, with an average sugar level between 11.5 and 13 °Brix.

Origin and general characteristics
'Earliblue' is a large-fruited variety of American blueberry (Vaccinium corymbosum), selected in the United States in 1936. It is distinguished by its remarkable earliness , its good fruit retention and its ability to produce a clustered harvest as early as June, making it one of the first varieties to ripen in the season. It is non-remontant, with only one harvest per year.
Fruit characteristics
Earliblue berries are large , generally measuring 15 to 18 mm in diameter and weighing an average of 1.5 to 2.0 g per fruit. Their shape is slightly flattened . The skin has a light to dark blue tint, covered with a well-marked bloom , a sign of quality on the professional market.
The flesh is not explicitly described in the sources, but the fruit is firm, juicy and suitable for mechanized or manual harvesting. The taste is balanced, sweet and tangy , although less intense in aroma than some so-called very fruity varieties. The average Brix level is estimated between 11.5 and 13 °Brix , which indicates a good natural sweetness.
'Earliblue' is known for its good shelf life after harvest. Its resistance to bursting in the rain makes it an excellent choice for fresh or short-circuit sales.
Plant characteristics
The plant reaches an adult height of 1.5 to 2 meters and a width of about 1 meter. It adopts an upright, sparsely branched habit , which facilitates picking and air circulation. Flowering takes place between April and May , with very early maturity from June. Production is grouped over about two weeks .
Its vigor is medium , which may imply slightly lower productivity than more robust varieties such as 'Bluecrop', but it is perfectly suited to intensive or semi-intensive management. Staking is generally unnecessary in open fields, except in cases of strong winds or when growing in containers.
The variety is melliferous , attracting bees when it flowers, which promotes natural pollination.
Growing conditions and resistances
'Earliblue' is self-fertile , capable of producing on its own. However, the use of complementary pollinators is recommended to improve fruit size and yield . The varieties 'Bluetta', 'Spartan', 'Patriot' and especially 'Bluecrop' are commonly used for this purpose. A mixture of early to medium-early varieties on the same plot is recommended.
Hardiness is good, with a cold tolerance estimated between -18 °C and -25 °C , which allows cultivation up to 1000 m altitude in the plains . The soil must be acidic (pH of 4 to 5.5) , well drained , and low in limestone . Earliblue is sensitive to root asphyxiation and water stress , particularly during installation and during the fruiting period. Mulching is recommended to maintain humidity.
Regarding diseases, the variety shows a marked sensitivity to stem dieback (Godronia cassandrae) . No specific resistance to pests is documented, and its resistance to anthracnose remains uncertain.
Performance and commercial uses
The yield per adult plant is on average between 3 and 5 kg per year , giving a potential yield of 6 to 12 tonnes/ha for a planting density of 2000 to 3000 plants/ha. This yield is considered average to good , although slightly lower than that of more vigorous varieties.
The 'Earliblue' variety is particularly suitable for fresh consumption , notably thanks to its precocity, firmness and resistance to bursting. It is also appreciated in processing , with a stable taste quality and good storage capacity. It is therefore a strategic choice for accessing early season markets , with outlets in direct sales, short circuits or industry.
Conclusion
'Earliblue' is a safe bet for professional producers looking for a very early variety , suitable for fresh sales and short supply chains . Its large size , firmness , good storage and tolerance to summer rains make it an asset on demanding markets. Careful management of irrigation and cross-pollination will optimize the full potential of this variety.
