The sentence you wrote is mostly correct, but it can be made a little clearer by adding a few small changes. Here is a corrected version:
"Squirrels often forget where they hid their stashes, and in spring, the buried seeds start to grow."
Explanation:
- Adding a comma after "spring" helps to separate the ideas and makes the sentence easier to read.
- The word "stashes" is correct, it means the places where squirrels hide their seeds.
- Overall, your sentence is good, and this small change will make it even better!
