Why Won't My Orchids Bloom?

People love orchids for their beautiful and long-lasting blooms. But one of the biggest mysteries for some gardeners is why their orchids won't bloom.

If your orchid sits in a dark corner, try moving it closer to a windowsill. Most orchids prefer bright, indirect light and won't bloom unless they're getting it.

Next, think about how you fertilize. Orchids need nutrients, but applying too much fertilizer can inhibit blooming.

Consider how old your orchid is. Some orchids won't bloom until they're at least five years old.

Also, many people aren't aware that most orchids need a 15- to 20-degree difference between day and night temperatures in order to flower.
