Can you compost strawberries

You can compost anything that was at any point a living thing.

All fruit, all vegetables, leaves, straw, paper products (careful with ink, a lot of it contains toxic heavy metals), wood, etc.

It is possible of course to compost animal products (meat, dairy, etc.), however they quickly create horrible smells and possible health risks unless done in a very controlled way which is generally not possible for the average gardener.

Check out a book, composting is really quite easy to master.
