Planting your own backyard vegetable garden is a great way to stretch your grocery budget and get back to the basics of food, but when planning your garden be aware of plants that don’t grow well together. For example, peas grow best with cucumbers, beans, and most other vegetables, but do not grow well with onions or garlic. And lettuce can be planted with strawberries, carrots, and radishes, but not with celery or parsley. While you should not plant tomatoes near calendula, you can plant the flower throughout your garden as a general pest deterrent. Marigold leaves can be used to make an organic general insecticide spray! You can plant yarrow near aromatic herbs to increase essential oil production.
