Companion planting is a popular gardening strategy that involves growing different plants together to enhance growth, deter pests, and optimize space. If you’re wondering whether garlic, sweet potatoes, and alyssum can be planted together, this guide will delve into their compatibility and provide practical tips for your garden.

Compatibility Analysis

Can garlic, sweet potatoes, and alyssum be planted together? Yes, they can be planted together, but with some considerations. While these plants have different growth habits and needs, they can complement each other when managed properly.

Why They Work Together
