Q.Orchid flowers
I’ve had an orchid plant for 3-4 years and after its first flowering, which lasted for 6 months, it has not flowered since. Will it flower or is it time to go?
Thank you.

No, certainly don't give up!
With some adjustments to the light, humidity, fertilizer and planting medium you can likely have lovely Orchid flowers again.
