Hi Mercedes your carrots wont be ready to harvest for a while yet. Give it another month and then look at thinning them (pulling 2 out of 3, or even more, small carrots) you can use these in salads or, if they are big enough steamed for a few minutes. The main crop will be harvested August/September time. Try to do any thinning on a windy day to keep the carrot root fly away.
