Once you have planted Decor the item is a permanent fixture in your garden. If you dislike the location where you placed the item, you have a 1 minute window in which you may return it for a full refund. After 60 seconds have lapsed, you can still receive half of your money back (rounded down, see note below) by selling the item. In the future there may be an update requiring maintenance on decor items to prevent them from expiring. This has not been implemented yet; but, keep that in mind when making your purchases.

Selling an item that costs gems will only return half the purchase price, rounded down for any odd item costs. For example, selling an item that costs 3 would only get you 1 .
