When thinning most crops, I naturally pull out the smallest plants, leaving the robust ones to grow and produce. This is how I used to thin carrots.
But if I thin the carrots by pulling out the biggest ones, I end up with a big bag full of beautiful little carrots to eat. Then the smaller ones will grow, and I’ll get to pick and eat them later on. Makes the thinning job so much nicer, because I know I’ll get dinner out of the deal.
