I am very new to itch.io and I found this game almost immediatly and I love it. I can't for the life of me figure out how to use the hoe and the fertilizer. Any tips?

you put dung into the fertilizer storage, then you take the fertilizer out of the storage and use it on the soil (without weeds). You use a shovel to dig up weeds, hoe to hoe the ground  (soil, no weeds)
