How to Synchronize Crop Harvesting

How to Synchronize Crop Harvesting in farmville.


In order to take a screenshot with all 33 standard crops ready for harvest I had to synchronize my planting so that everything was ready to harvest at the same time. This is not difficult to do, but does require some planning.
Window of Opportunity

Your window of opportunity is the period of time when all your crops are ready to be harvested. This is the period after your last crop is ready to be harvested and before your first crop begins to spoil. The maximum length of this window is determined by the amount of time it takes your fastest seed to grow. In the case of all seeds, this would be a maximum window length of 2 hours since Raspberries take 2 hours to grow.
Scheduling

Once you know the length of your window, the next thing to do is determine the time you'd like the window to fall on. This time period is key since it will determine the time periods when you can plant all of your seeds.

For me, to synchronize all seeds I chose my window to fall between 10am and 11am. This time period resulted in my earliest planting to occur at 6am (for 4 hour crops) and my latest planting to occur at 11pm (for 10/8/6 hour crops); both of which are times I am usually awake.

Here is the scheduling chart for all crops to be ready for harvest between 10am and 11am. You can shift the times in either direction if your window time is different.
Seed Grow Duration ↓ Planting ↓ Ready to Harvest ↓ Begins to Spoil ↓
4 Day Seeds 4 days before window @ 7am Window Day @ 3am 3 days after window @ 11pm
3 Day Seeds 3 days before window @ 7am Window Day @ 4am 3 days after window @ 1am
