Companion planting is something that I've studied for quite a few years so if you need help with that please let me know. I garden for profit so if you want to pick my brain I'm always around.
Perhaps adding in a scythe or a potato fork could be a subsection under rakes.
Also, are there flowers, herbs, fruits or vegetables that could be beneficial for magical use?
What about adding in a section to link to each cities specialized plants? There are some that have their own write ups on regional plants if I'm not mistaken.
That's all I can think of right now but I think what you currently have is pretty solid.
Look forward to seeing this developed thanks for volunteering!
(P.s. If you have questions about doing WD let me know I can help out with that too if you need.
P.p.s. Apologies if any of this is repeat of anything above.)
