Because blueberries have such particular soil chemistry requirements, some people choose to grow their blueberries in containers instead of in a standard garden. Of course, if you love blueberries but you don’t have enough or the right sort of land to grow them in a garden, a pot or container is the perfect solution!
For raised-bed plantings, the previous guidelines apply. For container gardening, the guidelines are much the same, but on a slightly smaller scale.
No matter where you plan to plant your blueberries, in order for them to thrive, they need soil with a low pH and active decomposition.
Here’s how to get started.
Step 1: Get your soil together.
- Equal parts 1/4-inch pathway bark, peat moss, and azalea mix or acid plant mix.
- A handful of soil sulfur for each plant.
- Mix this well and have it ready to pot your plants.
- Test your soil mix to make sure it has the right pH. Adjust as needed.
Step 2: Pick a pot. You need a container that’s the right size for your plant.
- Plants that come in a 4-inch to one-gallon container should go into 2- to 5-gallon containers.
- Established plants in 2- to 5-gallon pots should go into 16- to 20-inch containers.
- Put the blueberry plant in the center of the pot and fill in around the root with your soil mix.
- If you have a really big, heavy container, consider putting it on a plant stand on wheels; your back will thank you.
Step 3: Water & Fertilize.
- Don’t let your container dry out.
- Fertilize once a month with an acid-based fertilizer during the growing season. (This is the fertilizing exception to the rule, since the soil is limited.)
- WARNING: Never use fertilizer with nitrogen in nitrate form. It can kill your roots.
- Keep your pot in full sun as much as possible.
