Fresh produce,
every week

Join the Grafted Roots CSA for a 20-week season of field-grown produce at Chestnut Hill Farm. Market-style pickup where you choose your items, rotating gourmet mushrooms included bi-weekly, and no membership fees.

How it works

Simple from
start to finish

A CSA membership is a direct agreement between you and the farm. You commit to the season, we commit to growing exceptional produce for you every single week.

01

Choose your share

Pick from two share sizes — Seedling for smaller households, Harvest for larger appetites. Then choose the full 20-week season or any individual season.

02

Complete payment

Credit card — instant confirmation. Venmo, Zelle, check, or ACH — confirmed within 24 hours. Either way, your spot is locked in.

03

Market-style pickup

Walk through the farm stand display — everything harvested that week is laid out by variety. Choose your items. Mushrooms are pre-packed and waiting with your name.

04

Eat well all season

Receive recipe cards, farm updates, and the quiet satisfaction of knowing exactly where your food comes from.

What's inside
