When I began gardening, I wanted to start growing blueberries right away. One of the most healthy fruits you can eat, blueberries are not only expensive to buy at the grocery store, and they simply looked like so much fun to pick!
Growing blueberries is much simpler than you would think. All the work — which is minor in comparison to other plants — comes in the first year. After their first season, blueberries are very low-maintenance and will produce buckets full within a couple of years!
Before I planted my first bushes in the ground, I did extensive research. Pulling from that knowledge, my gardening experience with my own 7-year-old blueberry bushes, and experiences of others, I’ve compiled the most common beginner mistakes in growing blueberries and how to avoid them.
Mistake #1: Only planting one blueberry bush
Most blueberries are not self-pollinating, which means they need at least two different varieties to pollinate one another and produce berries. In other words, if you only plant one bush, you’ll get beautiful flowers but no fruit.
The minimum is two, but at least three will get you the best results. I chose to purchase five different cultivars, and I’ve had outstanding yields.
Mistake #2: Not checking the soil before planting your blueberries
Most garden plants tolerate a variety of pH levels in the soil, but this is not the case with blueberries. Blueberry bushes must have acidic soil — anywhere between 4.0 and 5.0. Many garden areas are acidic naturally, but I wouldn’t recommend hoping for the best. Blueberry bushes will last years, if not decades, and it’s worth your time to start them out right.
How do you know if your soil is acidic? The safest bet is to test your soil. Here’s how.
If your soil is not acidic, you can make plans to amend the soil with sulfur, build a raised bed, or plant in large containers. Blueberry expert Lee Reich shares more details in how to acidify your soil even the first year in this post.
Even if your soil is acidic, it’s a good idea to amend the planting area with peat moss. You can also include pine needles and coffee grounds (many coffee places, including Starbucks, will give you their used coffee grounds for free).
Mistake #3: Not mulching your blueberry bed
Blueberries have shallow root systems, meaning they will dry out if a thick mulch isn’t used to protect from evaporation. Plus, this mulch will help retain moisture already present in the soil from which the blueberry roots can draw. I cover my beds with 2-4 inches of wood chips or pine needles in both the spring and the fall. Here is a more in-depth discussion of mulch options.
Another benefit mulch has is preventing weed growth. Again, being shallow rooted, blueberry bushes will suffer from competition for water and nutrients.

Mistake #4: Planting your blueberries in a poorly-drained location
Blueberries do not like “wet feet.” My garden area is typically not well-drained, but I haven’t had any problems. One reason, I believe, goes back to how much organic matter (pine needles and composted wood chips) I added to the soil to begin with, in addition to the thick layer of mulch. These steps I believe prevent my normally wet soil from causing any problems for my bushes.
Still, making sure your blueberry bed is well-draining — or at the very least, well-amended — is important for the future growth of your bushes. Remember, these are not annual crops. Where you choose to plant your bushes the first year makes all the difference, and unless you make an effort to relocate them (which I wouldn’t recommend), where you plant them is where they will stay.
