Blueberry Vaccinium corymbosum (F)
ABOUT
Vaccinium corymbosum, commonly known as the highbush blueberry, is a deciduous shrub with a dense, multi-branched habit. It is well-regarded for its beautiful appearance throughout the year, offering interest in every season. The plant's leaves are broad, elliptical, and green, with a subtle, attractive texture on the surface. During the fall, the foliage transforms into striking shades of crimson and orange, making it a standout in the landscape. The highbush blueberry is also admired for its flowers. In spring, it produces delicate, bell-shaped white flowers that hang in small clusters. These dainty flowers attract pollinators and are a prelude to the plant's fruit. The fruit of the highbush blueberry is perhaps its most desirable feature. The berries are small, round, and boast a deep blue hue with a light, protective powdery coating known as bloom. These berries not only provide a visual contrast against the green leaves but are also a favored treat for both wildlife and humans because of their sweet flavor when ripe. The highbush blueberry's bark is also of note – it is smooth when young and, as it ages, becomes slightly ridged and may peel in strips, adding to its winter interest. Overall, the highbush blueberry is a versatile plant that adds beauty to any space throughout its seasonal changes.

WaterFor highbush blueberry plants, maintain consistent moisture, especially during the growing season. They should be watered about 1 to 2 inches per week. Mulching can help retain moisture. During dry spells, possibly increase watering, but do not let the soil become soggy. Overhead watering can help simulate natural rainfall. During winter, reduce watering, but do not let the plants dry out completely.
LightHighbush blueberry plants thrive in full sunlight. They perform best in a location where they can receive at least 6 to 8 hours of direct sunlight daily. However, in regions with extremely hot summers, they can benefit from light afternoon shade to prevent overheating.
TemperatureHighbush blueberry plants prefer a temperate climate with a winter chill to ensure proper dormancy. They can survive temperatures as low as 20 degrees Fahrenheit and as high as 85 degrees Fahrenheit. The ideal temperature range for these plants is between 60 and 75 degrees Fahrenheit.
PruningPruning highbush blueberry plants is essential for maintaining plant health, encouraging strong growth, and increasing fruit production. Prune annually during the dormant season, ideally in late winter. Remove dead or diseased branches, and thin out crowded areas to improve air circulation.
CleaningAs needed
SoilBlueberry plants thrive in acidic soil with a pH of 4.5 to 5.5. A well-draining mix with peat moss, sand, and pine bark is ideal. Ensure consistent moisture without waterlogging.
RepottingBlueberry plants need repotting every two to three years or when they outgrow their current pots. Early spring is the best time for repotting.
Humidity & MistingBlueberry plants prefer moderate humidity but are adaptable to various conditions. Aim for about 40-60% relative humidity for optimal growth.
Suitable locationsIndoor
Provide acidic soil, sunlight, and keep soil moist.
Outdoor
Full sun, acidic soil, water regularly.

Life cycleVaccinium corymbosum, commonly known as highbush blueberry, begins its life cycle when seeds germinate in spring, requiring a period of stratification to break dormancy. Seedlings emerge and develop into juvenile plants, forming an extensive root system and vegetative growth, primarily in the form of woody canes and broad, deciduous leaves. After 2-3 years, the juvenile plants mature and enter the reproductive stage, producing clusters of white or pink bell-shaped flowers which, upon pollination by bees and other insects, develop into small green berries. These green berries mature over the summer, turning blue and succulent when ready to be harvested. Following fruiting, the plant enters a period of senescence in autumn where leaves change color and fall off, and it undergoes dormancy during the winter months. In early spring, the cycle begins anew with the plant breaking dormancy and initiating new vegetative growth.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagation for the Vaccinium corymbosum, commonly known as the highbush blueberry, is through softwood cuttings. This is typically done in late spring or early summer when new growth is still tender and flexible. Cuttings about 4 to 6 inches long are taken from the current year’s growth. The bottom inch of each cutting is dipped in rooting hormone to facilitate root development. The treated cuttings are then inserted into a well-draining growing medium such as a mixture of peat and perlite, ensuring at least two sets of leaves remain above the surface. The cuttings are kept under high humidity, often with the use of mist systems, and in indirect light until roots have developed, which generally takes several weeks. After rooting, they can be transplanted to individual pots and grown on before planting out.
