Blueberries have been a welcomed addition to our permaculture homestead since the very beginning but it took time to get the soil conditions right for their optimal growth.
As most blueberry growers know, this finicky bush plant likes its soil a little different than most plants do. Blueberries like to grow in acidic soil conditions with a pH level between 4.5 and 5.0 and it may take a little work and time to get your soil in an optimal blueberry growing condition sometimes.
Because the perfect blueberry growing soil is acidic there are many plants you will want to avoid planting near blueberries. The fact is most plants love slightly alkaline soil for best growth. Although many can tolerate acidic soil, there are some that simply cannot grow well or possibly not at all in your blueberries soil.
Should You Grow Anything Around Blueberries?
Students of permaculture and organic gardening quickly learn the value of companion planting. By interplanting a variety of plants that are specially chosen, a gardener can accomplish many desired effects.
Companion plants can serve as a pest repellent to protect higher-value crops. Some plants function well as groundcover which helps with soil condition and water retention. Still, other plants can provide necessary nutrients and other types of support for fellow plants.
Another great reason to companion plant is for an increased yield in crops. By utilizing all the space you have by choosing plants that will help each other and can grow well alongside one another your garden becomes much more productive.
You certainly don’t have to plant anything with your blueberries but in true permaculture fashion, it will become a more useful space if you do.
Plants You Should Avoid Growing Around Blueberries
There are mainly 3 problems you are trying to avoid when choosing what to plant near your blueberries.
First, you need to be careful not to shade out your blueberry bushes. Blueberries love many hours of direct sunlight and many plants can grow taller than blueberry bushes.
This becomes less about not planting near blueberries but instead where to plant around your blueberries. Be sure to not plant anything that will grow taller than your blueberries between the bushes and the sunlight.
Second, you don’t want to plant anything that has different nutrient requirements than your blueberry bushes. Blueberries are sensitive to fertilizer and generally prefer to be fed with organic material added to the soil and a moderate amount of compost.
This being said, plants that are heavy feeders and require more nutrients from heavy applications of compost or even organic fertilizers are not good companion plants for blueberries as you could harm your bushes by catering to the needs of the companion plants.
Third and most importantly, plants that have different soil pH requirements than blueberries are not good companion plants as they will not thrive or possibly not survive the acidic conditions.
