The original sentence you wrote is:
Many animals store seeds and fruit for the winter. Squirrels often forget where they made their stashes, and the buried seeds start to grow.
Here's a corrected and smoother version:
Many animals store seeds and fruit for the winter. Squirrels often forget where they hid their stashes, and the buried seeds start to grow.
Explanation:
- Instead of "made their stashes," it is better to say "hid their stashes" because animals hide or bury seeds rather than 'make' them.
- The rest of the sentence is correct and clear!
So the corrected sentence is: "Many animals store seeds and fruit for the winter. Squirrels often forget where they hid their stashes, and the buried seeds start to grow."
