I want to see the flowers opening, but getting out of bed early is my great weak point.
It would be nice if the flowers would open later!
Morning glory flowers open earlier in September and October than they do in July. In July, when night falls late, the flowers open at about 4:00 a.m. But in September and October, when the sun goes down earlier, the flowers begin to open at about 2:00 a.m. You may think that the length of time from sunset to flower opening is almost the same. If you want the flowers to open later, you should delay the time of sunset by using artificial illumination (artificial lighting). |
Take a potted plant that has a lot of flower buds inside your house in the evening, and illuminate it with a fluorescent lamp until late into the night.
Then take the potted plant back outside in the dark, and observe the appearance of opening flowers for 2 or 3 days.
There is some difference according to temperature and variety, but a flower will open at 7 to 8 a.m. every day if you illuminate it until 10:00 p.m. every night.
What time will a morning glory flower open if you invert night and day by using a fluorescent lamp at night and putting the plant in a dark closet during the daytime? Test this idea under various conditions by considering the plan for yourself. |
