Congrats!
I bought my first home almost 3 years ago and it has been super stressful sometimes but SO rewarding being able to make everything just the way I like it!
I'm also thinking greenhouse for this next spring... Google 'hoop house' because if you're like me, you won't have a penny left after fixing things, buying furniture, installing an indoor garden, lol!!!
Maybe for a tree just decorate one of the trees OUTDOORS really nicely to make your new home feel more welcoming and festive!
