Afin productiv cu fructe mari - Vaccinium corymbosum 'Darrow'

Vaccinium corymbosum 'Darrow' , also known as 'Highbush Darrow' (Highbush Blueberry), is a blueberry cultivar in the Ericaceae family, renowned for its exceptionally large, tasty berries and high productivity . Native to North America, this deciduous shrub is valued for both its culinary value and ornamental appearance, making it an excellent choice for gardens or commercial crops.

Appearance of leaves, flowers and fruits

• Leaves : The leaves are oval, dark green , glossy, 4-6 cm long. In autumn, they turn into vibrant shades of red, orange and purple , providing an impressive decorative display.
• Flowers : In late spring (May-June), bell-shaped, creamy-white flowers with a pale pink tinge appear, grouped in clusters. The flowers attract pollinators, especially bees and butterflies, contributing to biodiversity.
• Fruit : The fruit is a very large , deep blue berry with a firm texture and a sweet-sour taste, ideal for fresh consumption, desserts, jams or freezing. They are among the largest fruits of the blueberry varieties, with a diameter of up to 2 cm. They ripen in mid-to-late summer (July-August).

Growth characteristics

• Height and width : It grows as an erect, vigorous shrub, reaching 1.5-2.5 meters tall and 1.2-2 meters wide , making it suitable for medium gardens or group plantings.
• Vigor : It has moderate to fast growth, with strong branches, forming a dense and well-structured bush.
• Type : It is a deciduous, multi-stemmed shrub that produces a few shoots from the root, but does not form extensive colonies.

Growing conditions

• Exposure : Prefers full sun for maximum fruiting, but tolerates partial shade , with slightly reduced production. A site sheltered from strong winds helps protect flowers and fruit.
• Soil : Requires acidic soil (pH 4.5-5.5) , rich in organic matter , well-drained , but moisture-retaining. The addition of peat, pine needles or acidic compost is essential to maintain optimal pH.
• Watering : It needs regular watering, especially during flowering and fruiting, to prevent the soil from drying out. A layer of organic mulch (e.g. bark, straw or pine needles) helps retain moisture and protect the roots.
• Pollination : It is partially self-fertile , but cross-pollination with other blueberry varieties with a similar flowering period (e.g. 'Bluecrop' or 'Toro') significantly increases production and fruit size.

Care and resistance

• Hardiness : It is hardy to -25°C (zones 4-8), making it suitable for temperate climates, including Romania. It tolerates winters well, but the shallow roots may require mulch for protection in very cold areas.
• Fertilization : Apply a fertilizer for acidophilic plants (e.g. for azaleas or rhododendrons) in early spring, avoiding excess nitrogen which can favor leaves at the expense of fruit.
• Pruning : In the first two years, remove the flowers to stimulate root and branch development. From the third year, prune in February-March dead, weak or older branches than 5-6 years to encourage fruiting and maintain the shape of the shrub.
• Pests and diseases : May be affected by fungi (e.g. gray mold) or insects (e.g. aphids, leaf beetles). Good ventilation, adequate drainage and removal of plant debris prevent problems. The fruits attract birds, so protective netting is recommended.
• Fauna : The flowers support pollinators such as bees, and the fruits are eaten by birds (e.g. thrushes, blackbirds) and small mammals.
