Cymbidium goeringii "Kourin" (Japanese) 日本春蘭「光琳」

[Asian Cymbidium Empress]

Cymbidium goeringii "Kourin" (Japanese) 日本春蘭「光琳」: Stage 1 shading is completed with a white flower bud. Now, it's time to continue shading the bud with an aluminium foil, remove the foil 2 weeks before it blooms next spring (spring 2022). The bud must go through vernalization (0C-10C at at all times) in the winter in order to bloom. The flower bud will stay this size (3cm-5cm) just 1 month before it blooms. This plant was received damaged with only 3 leaves 3 years ago. It started to bloom last year, this is the 2nd year in a row that it produced a bud. When following the Japanese C. goeringii culture methods, it grows strong roots and can bloom every year. Last picture was the bloom this spring (Feb 2021).

Do you grow all of your Cymbidium goeringii plants indoors, or do they go outside during the summer months?

[Asian Cymbidium Empress]

I live in Toronto Canada and C. goeringii blooms for me ever year, no problem. I grow them outdoor from early May to Halloween/early Nov. From early Nov to end of April, they are growing in the goeringii room in the basement underlight. You want to grow them outdoor as much as possible. it is hard to grow them because they have 4 different cultural conditions according to the season:

Light requirements:
They don't need much sunlight (morning sun only and don't pass 11:30am) especially from mid June to mid Sept. I change the amount of sunlight througout the year. When grown underlight, 12 hour light cycle.

Temperature: It is not a cool growing species, it is a hot to cold growing species.
Spring and fall: intermediate temp range 10C-20C
Summer: warm to hot temp range: 25C-30C
winter: cold range, 0C-10C
Winter must have this temp to do vernalization. If you don't stay in this temp range in the winter at all times, the buds will blast.

Watering: watering interval changes according to the season, from every 6 days to ever 14 days depedning on the month/season. C. goerngii is a seasonal orchid.

humidity; 50%-70% at all times, they hate low humidity.
