Orchid fans in Honolulu get a two-day show and plant sale this weekend, with displays, vendors, and free growing advice.

• The Honolulu Orchid Society holds its 87th annual show Friday and Saturday at Washington Middle School, starting at 9 a.m. both days.
• This year's theme is "Orchid Spooktacular," with displays from several local orchid societies and vendors selling locally grown plants.
• Speakers cover general orchid care, an "orchid doctor" clinic, and talks on Cattleya growing, with a University of Hawaii at Manoa extension agent leading the morning sessions.
• Care tips for the common Phalaenopsis: keep them out of full sun since they naturally grow under trees, and water more often than expected because they cannot store water.
• The society, founded in 1939, charges a low yearly membership fee, gives out free plants at monthly meetings, and meets the second Wednesday of each month.

Outlook: The show runs Friday and Saturday only, and memberships can be signed up for at the door, online, or at a monthly meeting.
