Introduction to Four Excellent Blueberry Varieties to Help You Choose the Right One
Blueberry, this fruit, has always been very popular with the public. Although its price is relatively high, demand remains strong; it has delicate flesh and a sweet-and-sour taste, and there is no shortage of people who love eating it. There are quite many blueberry varieties. Below, the editor will introduce the four excellent blueberry varieties.
The Four Excellent Blueberry Varieties
1. Gardenblue
A mid-season to late-season variety with strong, upright tree vigor; tree height 2 m, crown width 1.4 m. The fruit is medium-sized, with a strong sweet taste, light acidity, and a rich aroma. It has little bloom, and the skin is firm. It can also grow vigorously in plots with poor soil conditions, making it suitable for cultivation in parks, along walls, and similar sites. At present, the most ideal pollinator tree is Tifblue. Compared with highbush blueberry types, it is less strict about soil conditions, and the suitable soil pH for growth is 4.5-5.5. Gardenblue is relatively drought-resistant and tolerant of damp heat, but its cold resistance is rather poor. It is prone to cold damage at low temperatures below -15°C, so it is suitable for cultivation in warm areas. When developing it in northern regions, issues such as winter freeze damage and unseasonal temperature fluctuations need to be considered; when developing it in southern regions, it is necessary to consider whether the cultivation site meets the variety's low-temperature requirement for dormancy, generally requiring 300-800 hours at low temperatures below 7.2°C. It has strong adaptability to soil and is suitable for planting in most areas of Jiangsu, Zhejiang, Anhui, and Jiangxi. Planting it together with Tifblue gives relatively good results, with a planting spacing of 1.5-2.0 m.
2. O'Neal
O'Neal is one of the representative varieties of southern highbush blueberry and is suitable for cultivation in warm temperate to subtropical regions. The tree grows vigorously, with a height of 2 m, semi-upright, deciduous, blooming early, and with a long flowering period. It is early-maturing and extremely productive, with large fruit; when ripe, the fruit is blue-black with relatively little bloom; the fruit is spherical, with an average single fruit weight of 1.5-2.5 g. The flesh is fine and soft, very juicy, with a rich aroma and good flavor; the stem scar is small and dries quickly, making it tolerant of storage and transport. O'Neal is self-unfruitful and must be planted with a pollinator tree to set fruit fully; at present, the best pollinator tree is Sharpblue. Planting spacing is 1.2-1.5 m. The climate conditions in the south can satisfy its low-temperature dormancy requirement, with a chilling requirement of 400-500 hours, and it is sensitive to late frost. Under abnormal winter high temperatures, it is not easy to break dormancy, and off-season flowering will not occur. It has strong adaptability to soil and is suitable for planting in most areas of China's Yangtze River Basin, for establishing pick-your-own orchards or orchards supplying the fresh fruit market.
3. Sharpblue
Sharpblue is a newly bred variety developed artificially by using relatively cold-resistant rabbiteye blueberry types from northern China, wild evergreen blueberries from Florida in the United States, and rabbiteye blueberries suitable for growing in warm regions, among others, and crossbreeding them through technical means such as gamete crossing. Its characteristic is that it has a relatively low low-temperature requirement and is more suitable for planting in warm regions than northern highbush blueberry. It is better planted together with O'Neal, with a planting spacing of 1.2-1.5 m.
Sharpblue trees are 1-2.5 m tall, and taller ones can reach 3 m. The tree is vigorous and takes shape quickly. The fruit is dark blue, the stem scar is very small, the fruit is medium-sized, and its storage and transport tolerance is relatively poor. The chilling requirement is 150-300 hours. The suitable soil pH for growth is 4.3-5.5. It prefers humid, warm climatic conditions and is suitable for planting in Jiangsu, Zhejiang, Anhui, and Jiangxi in southern China. This variety has relatively large fruit, good quality, and a good fresh-eating taste. It can be cultivated as a variety for sale on the fresh fruit market and can also be cultivated as a processing variety.
4. Tifblue
An early-maturing variety with strong, open-growing tree vigor. The berries are medium-sized, with little bloom, and the flesh firmness is medium. The aroma is rich and the flavor is good. The stem scar is very small. The fruit ripening period is relatively concentrated. Late-ripening fruit is small and the skin is coarse. The flesh is firm, has good storability, is suitable for mechanical harvesting, and is suitable for fresh fruit sales. Shoot sprouting is limited to a relatively small area, so heavy pruning or taking cuttings is unfavorable for growth. It has strong adaptability to soil and is suitable for planting in most areas of China's Yangtze River Basin; planting Tifblue together with Gardenblue gives better results. The planting spacing is usually 1.5-2.0 m.
