National Garden Bureau (NGB) has announced the dates for California Spring Trials 2027 (CAST 2027) as April 6–9, 2027. This is Week 14, one week later than CAST 2026 in Week 13 because of religious holidays.

This industry event for brokers, growers, and retailers will again be held at multiple locations across California, offering an exclusive preview of upcoming ornamental and edible plant introductions. One key location change for 2027 is that the Ball Companies will now be at the Museum of Ventura County, in downtown Santa Paula, approximately 4 miles from their old location. In the event of further location changes, more information will be released via the California Spring Trials website.

Additionally, NGB has confirmed that CAST 2028 will be back to Week 13 with the dates of March 28–31, 2028.

Keep track of more pre- and post-CAST 2027 event coverage here on the Greenhouse Grower website.
