Sunday brings the annual Mayfair in Harvard Square, with the streets closing to traffic and filling with vendors selling everything from art to jewelry to bonsai trees. Five performance stages are set up for a variety of music and dance acts, all your favorite fair food is on sale, artists decorate the streets with chalk art and performers wander the streets on stilts or surprise you with stillness as living statues. Harvard Square is a great place to explore anytime of year, but Mayfair makes it 10 times so.

Denise Jillson, executive director of the Harvard Square Business Association, highlights another aspect of the upcoming Mayfair, which runs from noon to 6 p.m. (with a rain date of May 20):

This year, for the first time, Mayfair will include the Get Growing festival on Palmer Street. This new spring part of the annual Harvard Square Urban Agricultural Fair aims to inspire people to grow edibles, even in small spaces. We’ll have information on composting, nutrient density, beekeeping, raised beds, hydroponics, rain barrels, mushrooms, rabbits, herbs/good weeds and much more. Visitors can meet chickens, add to a map of urban fruit trees, buy locally raised seedlings and ask lots of questions. Even those with no outdoor space for gardening can find out how to grow herbs on a windowsill or harvest veggies on an urban farm.

In addition to the 200-plus artisans and merchants selling arts and crafts, jewelry and vintage clothing, and more than 40 food vendors, the event features roaming railroad train rides, hot air balloon rides with donations being given to charity and three beer gardens sponsored by Grafton Street, Border Cafe and John Harvard’s Brew House.
