Can I control what my wildlife harvest?

The simple answer is 'sort of'.  If you double tap on an item in your Garden, the chances are that your wildlife will harvest it again automatically.

Not always though. Sometimes they'll go for something else in the same item chain (and yes, it can be the lowest level flower) and, more rarely, they'll go for something else entirely. 

You also can take control of your wildlife's harvesting behavior by adjusting the Harvesting toggle in the Settings menu:

• Auto: Wildlife will continue to harvest items automatically on their own.

• Manual: Wildlife will stop harvesting automatically and will only harvest items when you explicitly direct them to (by double-tapping an item or dragging wildlife onto it).
