Gardenscapes: New Acres splits its garden-building simulation into many small tasks spread across multiple days. As you complete tasks, the percentage bar for the current day will advance. Once you complete the last task for that day, you will reach 100%, receive a reward, and you'll be able to start a new day. Starting a new day completely refills your energy bar up to 5 lives, so it's best to wait until you are out of lives to move on to the next day.
