Late June, early July
Duke is the most popular early blueberry variety in our region. It was developed by American scientists nearly half a century ago and remains the most widely grown commercial blueberry variety. High productivity, tasty, uniform, and attractively colored fruits are the main reasons for its popularity. The variety is suitable for mechanical harvesting. Fruits do not ripen all at once and are harvested in multiple passes, but they can be stored in cold storage for up to three weeks, allowing simultaneous processing. A mature bush can yield 6–8 kg, providing a substantial supply for winter through freezing, drying, or preserving the berries with valuable properties.
The berries have a sweet-tart flavor.
The fruits are large, oval, and light blue. Rounded berries reach a good diameter and weigh around 2 grams. The characteristic shade of ripe berries comes from the bluish bloom on the dark blue skin, which is dense and elastic. The pulp is moderately firm, juicy, with a subtle acidity underlying the sweetness.
Self-pollinating, but higher yields are achieved by planting multiple blueberry varieties.
Frost-resistant (tolerates repeated frosts); resistant to diseases and pests. Sensitive to drought.
You can purchase seedlings of Blueberry Duke at our garden center in the nursery located at Gornjem Crnjelovu, Glavna 65a.
Upon collection of the goods (seedlings), the Agromedžik nursery no longer has the possibility of supervision or care, and therefore cannot provide any further guarantee. Since seedlings are living beings, it is not possible to give a guarantee even a day after they leave the nursery. We cannot influence their maintenance and care, and consequently their further growth and development.
Our plants regularly undergo phytosanitary and vegetative inspections, therefore we do not have diseased or infected plants.
Planting is done from late October to mid-April, avoiding periods of frost and drought.
Trim the roots, then the branches into 3 to 4 rings. At the beginning of March, cut the seedlings to a height of 80 - 120 cm.
Before planting, soak the plant in water for at least 2 - 3 hours.
Dig a hole, in the previously prepared soil, measuring 60 x 60 x 50 cm for the soil (40 x 40 x 40 cm) so that the roots and part of the stem are well placed, taking care that the grafting point is outside the soil.
Place the plant in the hole and cover it with dry soil, gently press it down so that it gets well between the roots.
Fertilizer and seedling roots must not be in direct contact.

Pour with 20-30 liters of water. During periods of drought in the first year of planting, it is necessary to water young seedlings more often.
Containerized seedlings can be planted throughout the year.
