What to Consider When Choosing the Best Soil for Blueberries

While it’s easy to assume that all plant soils offer similar performance, a number of factors affect their functionality and appropriateness for different plants. Keep reading to learn about several of the most important features to consider when choosing the best soil for your blueberry bush.

Drainage and Moisture

Blueberry bushes have shallow root systems, so they need to be watered frequently to prevent the soil from becoming dry. Because of this, they need well-draining soil that also retains moisture well.

Consider adding a layer of mulch to the soil to aid in moisture retention. If inadequate drainage or moisture is causing blueberry plants to fail, consider moving them to a raised bed or container where the soil is more easily controlled. Check on the plants regularly, and water them if the top inch of soil is dry to the touch.

pH Level

One of the most important factors when choosing soil for blueberries is the pH level. Blueberries do best in acidic soil with a pH of between 4.5 and 4.8. Before you plant blueberry bushes on your property, check the soil’s pH level to determine if it needs to be raised or lowered. Gardeners can add sulfur to the soil in order to increase acidity.

Since the soil in the United States isn’t naturally acidic, soil that includes a pH modifier may be necessary. Choose a soil blend that includes peat moss or sphagnum moss, because they both work to increase a soil’s acidity level. Coconut coir is an ingredient that acts as an eco-friendly alternative since moss-harvesting practices are not considered to be sustainable. While choosing the right soil blend for acid-loving plants is key, it will still usually be necessary to add a soil modifier in order to reach the ideal pH level for blueberries.

Organic Matter

Blueberries typically do best if their soil contains organic matter that provides both macronutrients and micronutrients. Some great options include oak leaves and fir or pine bark, all of which acidify the soil while providing essential nutrients.

While some soil blends include organic matter that helps with fertilization, gardeners can also supplement with a dedicated fertilizer. Blueberry plants should be fertilized during their blooming season, and fertilizing stops in late summer in order to discourage further blooms before winter comes. For optimal results, choose a fertilizer with a balanced NPK ratio of 10-10-10 or similar.

While you now know more about choosing the best plant soil for blueberry plants, you might still want more information about how to grow blueberries, how to care for a blueberry bush, and how to use the soil. Here are some answers to some of the most frequently asked questions about blueberry plant soil.

Q: How do I prepare the soil for blueberries?

Before planting blueberries, test your soil’s pH level using a home test kit. Ensure the soil has an acidity level of between 4.5 and 4.8 by adding sulfur as needed. It’s best to continue to test the soil throughout the year to ensure it remains within the ideal range.

Q: What is the best soil acidifier to use for blueberries?

Most soil in the United States is not ideal for blueberries, so a high-quality soil acidifier containing sulphur like Espoma Soil Acidifier can help. It’s also important to test the soil’s pH after using a soil acidifier to make sure it’s at the optimal acidic level for blueberries.

Q: What is the best mulch for blueberries?

Pine needles, wood chips, or bark mulch are the best mulch options for blueberry plants due to their low pH.

Q: Where should I plant blueberry bushes?

Plant blueberry bushes in an area that receives full sun unless you live in a particularly warm climate where they appreciate a little afternoon shade.

Q: What type of blueberry plant is best for my area?

Choose a type of blueberry plant based on your USDA hardiness zone. Lowbush varieties are hardy to Zones 3 to 6, half-height varieties can thrive in Zones 3 to 5, highbush blueberries do well in Zones 4 to 7, and rabbiteye blueberries are best grown in Zones 7 to 10.

Q: How do I protect blueberry plants from birds and other animals?

Since birds and other animals are attracted to blueberries, consider installing bird netting over your plants in order to protect them.
