It’s time for Tiller Days and lots of plays. Fall fun is in full swing, with spooky theater and other harvest-themed events on tap. Here are our picks for the weekend to come:

ALL WEEKEND

TUSTIN TILLER DAYS: For 60 years, the Tiller Days of Tustin has invited the community out for family fun that celebrates the Orange County heritage with everything from pancake breakfasts to hair-cutting and cake decorating contests. The three-day affair will include a parade (starting at 10 a.m. on Saturday), a carnival, rides, food, craft beer tastings, dancing and live entertainment. 4-11 p.m. Friday, Oct. 6; 10 a.m. to 11 p.m. Saturday, Oct. 7; 11 a.m. to 8 p.m. Sunday, Oct. 8. 17522 Beneta Way, Tustin Information: 714-573-3326 or tustinca.org

‘TRIBES’: What happens between the hearing-impaired and those with hearing is the focal point of Nina Raine’s 2010 play “Tribes.” Its superlative Orange County premiere at Chance Theater also effectively depicts the distinctive challenges facing those who live in an audible void. The play’s focus is a comically dysfunctional British family – parents Beth (Marina Coffee) and Christopher (Bruce Goodrich) and their adult children Daniel (Jonathan Fisher), Ruth (Piper Power), and Billy (Miles Barbee) – all of whom live at home. Through Oct. 8. 8 p.m. Fridays, 2:30 and 8 p.m. Saturdays, 2:30 p.m. Sundays. Cripe Stage, Chance Theater at Bette Aitken Theater Arts Center, 5522 E. La Palma Ave., Anaheim Hills. Tickets: $21-$35. Information: 888-455-4212, chancetheater.com. (Read more about the play.)

Chapman Ave., Fullerton. Information: 714-992-7135 or horticulture.fullcoll.edu.

‘DEATH BY DESIGN’: “Death by Design” depicts the goings-on at the country home of a well-heeled playwright and his actress wife, where the light comedic atmosphere is shattered by the murder of one of the couple’s guests. Newport Theatre Arts Center’s production of the 2013 revised version has the distinction of being the play’s Orange County premiere. It’s also loaded with Noel Coward-like lightheartedness and, after the murder, a touch of Agatha Christie-like atmosphere. Through Oct. 15. 8 p.m. Thursdays-Saturdays, 2 p.m. Sundays, 2 p.m. Oct. 14. Newport Theater Arts Center, 2501 Cliff Drive, Newport Beach. Tickets: $20. Information: 949-631-0288, ntaconline.com. (Read more about the play.)

‘CURVE OF DEPARTURE’: Commissioned by South Coast Repertory, “Curve of Departure,” now being world-premiered on the Argyros Stage, also shows that interracial marriages can still give rise to snags – not between the marrieds, but with their relatives. The family that congregates at a hotel in Santa Fe, New Mexico, for the impending funeral of one of its members is a mixture of races, religions, ethnic backgrounds and gender orientations. Through Oct. 15. 7:30 p.m. Tuesdays through Thursdays, 8 p.m. Fridays, 2:30 and 8 p.m. Saturdays, 2:30 and 7:30 p.m. Sundays.
