Zero Waste Guide to Companion Planting

What is companion planting?

Companion planting means allowing your plants to grow next to their buddies. Plants are particular, and just like us, they have likes and dislikes. Tomatoes, for example, love basil, but hate dill. Cucumbers love dill, but hate potatoes. Who knew?

Some plants help each other thrive by repelling certain pests, by providing nutrients to the soil, or just by not totally taking over their space. Other plants might attract a certain pest to the other. Potatoes and tomatoes are both affected by the same blight, so although they might not “hate” each other, it’ still best to keep them apart. In these cases, we will categorize them in the “dislike” category.



Here is an *almost* complete guide to companion plants:
