Orchid Crosses Failing: First Blooms, Temperature, and Age

Why New Crosses Drop Buds

First flowerings are often weak—future blooms improve on well-grown plants.
Purchased-in-bloom plants may have open flowers near natural senescence.
Temperature sensitivity: Buds/flowers abort below 60°F or above 85°F. Your foggy 50-60°F mornings are risky.

Optimize temperature stability; expect better results in subsequent bloom cycles.
