The format won't be too great, but as you can see, every berry has a set amount of time that it takes to go from planting the berry to picking them. When you water the berry during a stage, you increase the number of berries the tree/bush/plant will produce. Now, if you don't pick the berries when they are ripe, after a while they drop to the ground and the process starts over. That means the ground will be furtle for one cycle before the sapling cycle starts. During that time you are certainly able to plant another berry, but if you do you just lost the berry you planted previously.
