We've fended off the birds. The rabbits. The slugs. The snails*. But nothing, NOTHING, can fend off a toddler from a strawberry patch. Red or green strawberries, he's unstoppable. They're pretty easy to grow, especially as people often give away strawberry plants for free, and such a happy past time - would heartily recommend.
* Snails, incidentally, have 14,000 teeth. Our older mini explorer thoroughly enjoyed that fact. Whilst his brother demolished the strawberries.
