Hi Gemma,
Congrats on the new deck! A planter box for herbs sounds like a fantastic idea, both for the look and the convenience. Many herbs do prefer full sun, but there are plenty that can thrive in partial shade. Herbs like mint, parsley, cilantro, and chives are more tolerant of shady conditions.
Make sure to use good-quality soil and keep an eye on watering, as shaded areas can stay moist longer, and you don’t want the roots to get too soggy. Also, consider placing the planter box in a spot where it might get a bit of morning or late afternoon sun, if possible.
Hope this helps! If you would like to learn more, you might find my Easy Guide to Growing Herbs helpful: https://thepotagerproject.com/guide-to-growing-herbs/
