Looking at the “What’s Available” chart on the GrowNYC website — this is the organization that runs the city’s farmers’ markets — is usually helpful. If you can find fresh summer squash in the month of May, the date can’t be much earlier than the 30th or the 31st. The spring farmers’ markets are a bizarre mishmash of items that range dramatically in quality and provenance. The apples come from refrigerated storage facilities, placed there in November. Most every farmer either rents or owns refrigerated storage space in order to keep selling through the winter and into the misleading spring.
