Strawberries are a welcome addition to any garden and are a plant that fits well with many other plants as a companion. However, there are some things that should never be planted near strawberries for a variety of reasons.
When I first introduced strawberries to my homestead many years ago I broke quite of a few of these rules because I didn’t know any better. That being said, my strawberries still grew well but to have the best chance for success your strawberries should be put together with the best partners.
Should You Grow Anything Around Strawberries?
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 strawberries but in true permaculture fashion, it will become a more useful space if you do.
Reasons You Should Avoid Growing Some Plants Around Strawberries
There are mainly 4 problems you are trying to avoid when choosing what to plant near your strawberries.
Shading
First, you need to be careful not to shade out your strawberry plants. Strawberries can tolerate a certain amount of shade but also love many hours of direct sunlight and most plants can grow taller than strawberry plants.
This becomes less about not planting near strawberries but instead where to plant around your strawberries. Be sure to not plant anything that will grow taller than your strawberries between the plants and the sunlight.
Nutrient Requirements
Second, you don’t want to plant anything that has different nutrient requirements than your strawberry plants. Strawberries generally prefer to be fed with organic material added to the soil and a generous amount of compost.
This being said, plants that require a lower or higher amount of nutrients may not do as well in your strawberry plants soil or compete with your strawberries and starve them. If you plant these near your strawberries you could harm your plants by catering to the needs of the companion plants instead of your strawberry plants.
pH Requirement Differences
Third, plants that have different soil pH requirements than strawberries are not good companion plants as they may not thrive is optimal soil for strawberries.
The ideal soil pH for strawberries is between 5.4 and 6.5 so also avoid plants that prefer a lower or higher pH if you want all your plants to thrive.
