Although asparagus can repel most pests, affecting marigolds and basil, they don’t work well with fruits and vegetables, especially potatoes, onions, and garlic, which hog much space in the soil.

If you try to grow asparagus and other plants together, they can be stunted in the growth because they can’t take enough nutrients.

Strawberries And Cabbage

To solve this problem, you can grow strawberries with onions, sage, and thyme to repel properties. Growing cabbages with herbs, thyme, onion, mints, rosemary, dill, or celery can keep many pests away.

In general, you shouldn’t grow plants with a big height difference together because one plant can take the sunlight. What’s more, you shouldn’t grow plants that will complete nutrients and water together.
