Hence scientists discovered the role of mulches in growing blueberries.

Blueberries do grow best in an acidic and well-drained soil that is completely free from weed. Soil pH between 4 to 5 is optimum for growing blueberries that grow and tastes best. If the soil root zone is too wet, it will suffer a higher pH level. 

You should choose a mulch that offers greater moisture retentions so that the root zone doesn’t need to get flooded with excess water. Additionally, mulching helps to bring down root growth in certain types of shrubs. This includes blueberries as well.

As there are plenty of options available for mulches, the perfect one would be depending on the plant you are trying to grow. The common type of mulches includes pea gravel, bark chips, sawdust, peat moss, and leaves. Although their task is quite the same, some are particularly more effective for a specific shrub that you can grow.

Look for a mulch that has a strong shell as they tend to be durable. Mulches that have a stronger outer shell like the pine or bark chips provide extra protection against external conditions. Also, they tend not to get washed out by excessive watering or heavy airflow.


What Kind of Mulch is Best for Blueberries?

Now that you know what determines the selection of blueberries, let me discuss some types of mulches that work well for blueberries. 

  • Acidic mulch for blueberries

Pine needles, pine bark, and peat moss have a higher pH level of 3.5 to 4.5 and is considered acidic mulch. Blueberries often require acidic soil and you need to apply fertilizer to keep the level at a minimum. However, you should use an acidic mulch to a certain extent to avoid making the soil too much acidic.

  • Bark as mulch

While growing blueberries outdoor in your garden, barks are the best kind of mulch that you can use for your plant. They efficiently retain moisture in the soil and will provide you with greater control of weed growth. The bark mulch blocks weed emergence so that they don’t absorb the necessary nutrients that are needed for your blueberry plant.

  • Cedar mulch

About 2 to 4 inches of mulch is often enough for blueberries as they have shallow and dense roots. Though there is plenty of great option to be used as mulch other than cedar, dead cedar often provides greater benefits for your blueberries. This includes enhanced weed control, retention of moisture, and temperature regulation of soil.

  • Pine bark mulch

Pine bark is a perfect match for growing blueberries and strawberries. The exact level of pH that blueberries require to grow is in pine bark. As blueberries don’t enjoy heavy soil, pine bark will ensure that your soil is loose enough by retaining moisture effectively. Paired with a decent fertilizer, your blueberry plant will be growing and thriving in no time.

  • Wood Chips

While choosing mulch for your blueberry, you should focus on whether the mulch is noose enough for the water to reach the root of your plant. In this case, wood mulches such as pine needle and bark one do quite a great job as mulches. Although, you should keep in mind that dyed mulches need to be avoided at all costs as well as synthetic and black plastic ones.

  • Peat moss 

So far, you must have figured out that blueberries do enjoy acidic soils. And guess which kind of mulch provide you soil with extra acidic supplements? Peat moss of course. You must incorporate peat moss with blueberries in any way. Be it from fertilizer or mulches.

You can even mix peat moss with certain types of bark mulches to prepare an effective compost. Though you should avoid using redwood or cedar with peat moss.

  • Sawdust mulch 

Among other types, this one is probably the best type of mulch that you can use for your blueberry plant. Similar to peat moss, sawdust is also an acidic and probably better performer for acid-loving shrubs such as blueberries and rhododendrons.

Peat moss can be quite expensive and if you are on a budget, sawdust is the best economic choice for you to be used as mulches.
