Hello, I accidentally "dug" a patch in my garden, and now I can't plant the bean I was so looking forward to growing! Is there anyway to fix the patch so that I can plant my bean?
Nope. You get what the house comes with when you buy it. Maybe someday that will be an option when they get housing customization in, but for now, you just have to judge what you need when you buy your house.
ETA: The large cottages have the most tree patches at 5. The 50k houses are next with 4 patches.
