Planting requirements for the darrow's Blueberry differ between varieties. Ideally, use bag seedlings that are two to three years old when planting a darrow's Blueberry, with the diameter of the base of the main stem being more than 5 mm.
If garden centers provide bare-root seedlings, these can be stored in a damp and dark environment before planting to keep them in dormancy. The criterion of "dampness" is that the roots must be kept moist, but not fully saturated. Ideal planting time is usually late winter or early spring, before the plant starts sprouting new buds. Soak the roots of bare-root seedlings in water for 3 or 4 hours before planting.
Two or more plants of different species, with the same florescence, can be planted at the same time. Pollination between different plants can increase the fruit setting rate, as well as the single fruit weight. For species with a larger plant shape, the spacing should be appropriately increased.
If you are planting darrow's Blueberry into a pot, place this in a shaded and well-ventilated room for a week, before moving it outdoors and resuming with normal care. If on sloping land, avoid planting in locations where cold air stagnates, so that the plant is protected from frost during flowering. Adequate irrigation should also be carried out after planting. Maintain an organic mulch at a thickness of 5 to 10 cm throughout the year after planting.
A mulch such as broken wood sawdust, peat, pine needles and fallen leaves can help maintain soil acidity. As acidic organic matter degrades every year, the pH value of your soil needs annual monitoring, with adjustments as needed. Once the pH value of the soil is higher than 5.5, the darrow's Blueberry roots cannot absorb iron, meaning that the edges of leaves will lose their green color and turn red. Growth will be stunted, and the plant could even die. An acid peat soil mixture, while useful, takes effect slowly. If there are signs of an iron deficiency during the growing season, a chelated iron foliar fertilizer can be sprayed and a sulfur powder can be used to adjust the pH value of the soil.
