There are several reasons why we want to grow blueberries in containers. Maybe there’s simply not enough space to plant an old-fashioned blueberry patch. The soil may not be suitable for blueberry cultivation. Some gardeners have physical problems that prevent the soil from bending back, digging, and maintaining it. Here are some tips to get you started:
Choose wisely: It’s best to choose varieties of blueberries that perform well in containers. “NorthSky”, “Sunshine Blue” and “Patriot” are suitable for container cultivation. The dwarf Bushel and Berry series of blueberries are also grown small and fit well in containers. Keep in mind that blueberry yields will be best if you have at least two different varieties of women close to each other. Even if the plant is labeled as self-fertilizing. Standard northern tall bushy blueberries go well when planted in a large container.
Consider the container: The dwarf blueberries should be planted in a container at least 18 inches wide and about this depth. Northern, bushy blueberries need a pot at least 24 inches deep and about 18 inches deep. That means a 15-20 gallon preschool container. If the soil is not suitable for growing blueberries, you can sink these large containers into the soil, leaving the top of the container about 4-6 inches above the ground line.
Don’t skimp: Blueberries are extremely picky about the soil. This means looking for gold for the planting mix. The cost of planting blueberries in good soil can exceed the cost of the plant. Blueberries achieve best in an acidic, well-drained planting medium. You can also make your own mixture by mixing equal proportions of peat moss, acid planting mixture and mini pine bark or pine sawdust. There are also excellent pre-made blueberry mixes. This type of soil provides the pH of the acidic soil favored by blueberries for plants, which is 4.3-5.5.
Fertilization: Blueberries need an acid type fertilizer with a high nitrogen content. Acid fertilizers help maintain the ideal pH of blueberries. Cottonseed meal and blood meal are an excellent natural fertilizer that blueberries love. Use them for coffee bags first in early spring when the buds start to open and then in late spring. There are also excellent premixed fertilizers for acid-loving plants.
From the end of winter to the middle of spring it is time to fertilize blueberries. At this point, blueberries show new growth and actively absorb nutrients. Summer or fall apps are not good.
Full sunshine: Blueberries need at least six hours of sunlight a day. More on the misty shore. Well-groomed shrubs always look good even in less sunshine, but the yield is low and the taste is mild.
Water: Never allow blueberries to dry out during the summer fruiting months. Plants should be soaked at least once a week on the beach, more often if grown on land.
