One benefit of growing plants from seeds are that the plants will be much more hardy and resistant to disease. Growing blueberries from seed is not too difficult, but it does require some patience and adequate preparation. The main concern will be to make sure you have the right soil pH in the location you want to grow your blueberries. Blueberry plants need acidic soil to thrive in or they won’t do well. You will need to get your soil to a pH of 4 to 4.5. You can buy soil testing kits at your local nursery or online: Soil pH tester, pH Control Kit.
How to Grow Blueberries from Seed
If you grow blueberries from seed it will take three years until the plants start producing a lot of blueberries. It’s worth the wait though if you end up with lots of healthy blueberry bushes.
Indoors: The ideal temperature for germination is approximately 20°C (70-80 F). Surface sow the seeds onto a 50/50 mixture of moistened sphagnum peat moss and compost. Blueberry seeds require light to stimulate germination.
If germination is taking longer than expected, try finding a sunnier location for the seeds. Also try to find a location with good air circulation to avoid fungus problems. Keep the mix moist but never soggy. Don’t let the soil dry out. When the seedlings have developed at least two sets of leaves they can be transplanted outside after risk of frost. Germination can take approximately 4-8 weeks.
Outdoors: Prepare the soil by mixing in peat moss and compost. Presoak the soil and surface sow the seeds. Lightly cover the seeds with compost. Sunlight will be able to penetrate the soil and stimulate germination. It’s important to continue to keep the soil moist until during the germination process. If the soil drys out it can kill the seeds. It’s recommended to start the seeds indoors where the conditions are easier to control.
How to Plant Blueberry Bushes
The location of your plants is very important as well. Blueberry bushes require full sun to produce a large harvest of berries each year. They need to be in a climate that has a dormant cold period where the temperature reaches near zero. The dormant period doesn’t have to be very long. The soil needs to be acidic with a pH of 4 to 4.5.
The bushes need to be well watered, so it’s a good idea to mix in a lot of sphagnum peat moss to help maintain moisture. Also adding some mulch on top of the soil will help keep it from drying out too much.
