Gardenias typically bloom from late spring through early summer, with some varieties continuing to bloom sporadically throughout the summer and even into early fall under favorable conditions. The blooming period generally starts as early as March in warmer regions and can extend until June or later. Different gardenia varieties may have slightly different bloom times—some bloom in late spring and again in fall, while others mainly bloom once in spring. Key points about gardenia blooming:
- Bloom buds are set in the previous season, usually forming December to January.
- The normal bloom time is late spring to early summer.
- Blooming can extend sporadically through summer and sometimes into early fall.
- Gardenias require specific temperature ranges to form buds (daytime 65-70°F, nighttime 60-62°F) and to maintain blooms (daytime 70-75°F, nighttime 58-60°F).
- Proper light, moisture, temperature, and soil acidity help promote blooming.
So, in summary, gardenias bloom primarily in late spring and early summer and can continue with intermittent blooms into early fall depending on conditions.
