What should you do when your beautiful Four O’clocks aren’t blooming? Why are they seeming to hide from you, despite having buds? It’s always a shame when you’ve grown the plant up from a seedling but can’t seem to coax flowers from it. Here are some good tips to get them to shine.
Key Takeaways:
- It’s so frustrating not to get that reward you’ve been working towards. It’s a common complaint with four o’clocks, in particular, and there’s usually a very good explanation.
- Sometimes they bloom during the day if the sky is overcast and the air is cool.
- This means that the flowers will only open when daytime temperatures cool off, often a lot later than 4 pm.
“Four o’clock flowers, on the other hand, respond to temperature, and they don’t like the heat. This means that the flowers will only open when daytime temperatures cool off, often a lot later than 4 pm. They may open at 6, or 8, or only when the sun is down.”
