One benefit of growing plants from seeds are that the plants will be much more hardy and resistant to disease, and it can save you a lot of money. 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 starting the seeds indoors sow the seeds on the surface of 2-3” of moistened sphagnum peat moss and keep at a temperature around 20°C (70-80 F). If starting outdoors you will want to do the same but lightly cover seed with peat. The seeds normally will only germinate with light. Keep the mix moist but never soggy. Don’t let the soil get to dry until the seeds have germinated and have at least two sets of leaves. You will want to keep them moist but they will be much hardier at this point. Germination can take approximately 4-8 weeks.
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 when planting your bushes. Adding some mulch on top of the soil will help keep them from drying out too much.
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.
