Join the NPA

NPA membership dues cost as little as $35 per year for individuals and $75 for business memberships.

Memberships start in January and run through December, although you can join anytime during the year. If you join after September, your membership will extend through the following year. Memberships after March 15 will be charged $5 more to cover the increased costs associated with individually mailing the Open Gardens directories versus bulk mail.
