Blueberry bushes are relatives of rhododendrons and azaleas: they are not only fruiting plants but can also be an attractive addition to your landscape. Their deep green foliage turns scarlet in the fall.

And during the spring, these plants will brighten your yard with beautiful creamy-white bell-shaped blooms.


Before planting one in your garden, you should ensure you have the necessary space to support this plant’s growth. So, it helps knowing how big these bushes can get.


And for your information, they usually grow to become between 1 and 12 feet high and wide. But these shrubs are relatively slow-growing: it takes them about ten years to reach their mature full size.


However, the size of a blueberry bush depends on the variety. You can find dwarf species that only grow to about one to three feet high and even larger ones.

There are four main types of blueberries: rabbiteye, highbush, lowbush, or hybrid half-high. Inside each category, you’ll find several species. Ensure you choose the one best suited to your region to avoid struggling to grow it.

Planting blueberries

Select a sunny spot in your garden with some protection from harsh winds to plant your blueberries. Consider getting one to three-year-old plants: you’ll get harvests much sooner (and save yourself some time and effort)!

Also, avoid picking a spot close to a tree: they might compete with blueberries for water and nutrients (and might even block the sunlight from hitting your bushes).

Don’t forget that blueberry bushes have shallow roots: you’ll need to give them well-draining soil and prevent them from getting wet feet.

You can add a layer of mulch around your plants to improve water retention and keep your shrubs moist for longer. This step is especially crucial if you live in a region with hot and dry summers.

Soil type

Like their cousins (rhododendrons and azaleas), blueberries too thrive in acidic soils. Make the necessary amendments to bring your substrate’s pH between 4.0 and 5.0. Too much alkalinity might result in stunt growth.
