Due to their different soil and water needs, Brussels sprouts and strawberries should not grow together. Brussel sprouts survive in alkaline soil that drains well. On the other hand, strawberries thrive in slightly acidic soil with regular moisture.
Besides, strawberries can take over the space allocated to the Brussels sprouts and also get most of their nutrients. As a result, the sprouts’ chances of survival will be slim.
Both tomatoes and Brussels sprouts use up a lot of nutrients and moisture. Hence, growing both plants in the same place will limit their yield. Moreover, they can both render the soil infertile as a result of constant competition for nutrients.
While cabbage has the same water requirements as Brussels sprouts, they’re both prone to the same pests. In a situation where the cabbage suffers a pest infestation, your Brussels sprouts will suffer the same attack.
In addition, the cabbages will be competing with your sprouts for nutrients, water, and space. If you’re planning to grow both plants, leave a lot of space between them.
