Stratified Blueberry Seeds
This product is a mixture of northern variety highbush blueberry seeds. The plants produce large, delicious berries! Blueberries are great for eating fresh, making desserts, or jellies. Highbush blueberry plants are deciduous shrubs that can grow up to 12 feet (4 m) tall and are often found in dense thickets. They can be trained to grow as ornamental hedges. The dark glossy green leaves are elliptical and up to 5 cm long. In the fall, the leaves change colour to a brilliant red. They have excellent ornamental value. The flowers they produce are white, bell-shaped, and about 10 mm long.
It is preferable to grow blueberries with at least one other variety; the cross-pollination of two different varieties of blueberry will produce higher-yielding crops and larger berries. Not all blueberry varieties can self-pollinate, so the plants need to be grown within 100 feet of each other, preferably with a different variety of blueberries. Blueberry seeds require a cold dormant period to increase germination success. These seeds have been stratified (kept cold for 4-8 weeks), which increases the germination rate. All of my seeds come with growing instructions on the seed pack.
Acid Loving Plants
It’s important to note that blueberry plants need to be in acidic soil to thrive; they will thrive in soil with a pH between 4 to 4.5. One of the best mediums to germinate blueberry seeds is Canadian Sphagnum peat moss. Sphagnum peat moss is a sterile medium with a pH of around 4. If you are unsure of your soil’s pH level, you can purchase a pH test kit from your local garden store. You can also buy products to amend the soil and increase or decrease the pH levels.
Blueberry bushes are a great addition to the garden as they will attract a large variety of birds and insects that will also prey on nearby garden pests. Wild strawberries are also acidic-loving plants that can be grown at the base of blueberry bushes, and this can help maximize the use of your garden space.
When starting blueberry berry plants from seed, the plants will take at least three years to mature and produce berries.
Growing Blueberries from Seed
Surface sow the seeds onto 2 inches of sphagnum peat moss or potting soil if growing blueberries indoors. Place the seeds in a location with indirect light. During the germination process, keep the seeds moist and humid. Do not let the soil dry out completely, as it can kill the seedlings. If starting the seeds outdoors, cover the seeds lightly with peat moss or soil. Don’t give up if you think the seeds are taking too long. The seeds can take anywhere from 4 to 8 weeks to germinate, depending on the conditions.
