Horacio will also watch over your Jade Vine for a fee of 10 Wildblood hops. If you try to pay him again, he will say "I'm already watching over your vine! You have ears like corn!".
Horacio also sells basic farming tools, which can be accessed by talking to him and asking Can you sell me something? It is not an actual shop and it has no set stock; each item has to be bought individually through the dialogue.
