Can You Plant Them Together?

Yes, you can plant cauliflower, sweet potatoes, and oregano together, but with some considerations. These plants have different growth habits and needs, which can be balanced with careful planning.

Why They Work Together

• Container vs. Garden Bed: Use garden beds for better root development, but containers can work with careful management.
• Soil Preparation: Amend soil with compost to improve fertility and drainage.
• Additional Companion Plants: Consider adding marigolds or nasturtiums to further deter pests.
