Does anyone have any surefire tricks for getting their morning glories to bloom, and stay blooming?

I never water ones I have in the ground, but they still think it's a good idea to expand leaf growth.
The past 2 years I've tried in-the-ground plants I get lots of flowers from late summer till first frost, but the seeds are always just a little immature.

The ones in pots, I could maybe water less...
Anybody have success keeping them consistently thirsty?  Seems like it might harm them too much.

The only way I've seen to get quick flowers is really small pots.  Maybe I should try more of that.
Bonsai heavenly blue?

My mom always gets them to bloom and produce seeds with no problem.

 I don't have any experience getting them to seed though. This is the first year I'm growing them. I have around 7 giant heavenly blue morning glories that should be flowering soon. They don't have buds yet from what I can see.

Change the nutrients they are given. Find a fertilizer you are comfortable using marked ¨Bloom¨, should do the trick. Dont forget to aerate the soil around the area fertilized. However most heavenly blue dont normally start flowering for 90 - 100 days.

Nana, do you know if they autoflower or do they flower based on light hours?

Nana, do you know if they autoflower or do they flower based on light hours?

for me they flowered basically year round back in alaska (the hours of light varied from 5 in winter to 21 in summer) - so i wouldn't think it is based on light.

In my experience, to encourage flowering in morning glories once the first 3-4 months of growth have passed, give them as much sun as you can, avoid nitrogen rich fertilizers and soils -that will encourage growth, not bloom- do not overwater, and give them plenty of phosphates.

The unpredictable factor is genetics. If you started seeds produced by plants growing in a climate like yours, you'll get the best results. Otherwise, it might take some more time for them to adapt their morphology to your environment.

We have a heap near the fire pit that were not flowering. Had a huge fire, and the down wind side got a bit scorched one afternoon, and the stress seemed to kick them into reproduction mode.
They flowered 2x as quick as the others on the other side of the pit that didn't get burnt by the really hot winds/smoke.
They are dying back now, and we have picked most of them, but the ones on the left that were unharmed are still pumping along steady steady.
Much lower yield and the plants looked raggedy, but if you ever want to sped things up, a bit of heat/smoke damage to the stems might be worth a crack?
In moderation of course.

Some are close to what could be considered auto flower, but this tends to vary widely. Like Mandrake said genetics make things pretty unpredictable. My heavenly blue started flowering at 95 days and have kept a 56 day cycle (following the moon phase) of flowering and not flowering (56 on / 56 off). Now the G. Ott variety I have started producing flowers at one week and have not stopped in almost 2 years.  I grow mine in beds and keep them pretty dry, the leaves normally wilt every day at about 2pm because of the heat here.

I have not tried exposing them to fire, i might try that now.

Thanks much for the advice, guys.  I'll be on the lookout for some quick-flowering varieties, maybe Clarke's Heavenly Blue is better than the heirloom varieties I planted.

I like the ideas for alternative stress factors too.  I'll have to try fire, maybe a sudden shift in pH would work too, or photoperiod fluctuation.  Of course, all next year.

My heirloom Pearly Gates did bloom, but only by the beginning of September, so I remain doubtful I'll get any seeds this year.  Damn temperate climate!

Mine just started blooming too and I'm in zone 5b bro. I think we'll get seeds no worries.

The whole mg plant is special, and is full of specialness!

Pretty flowers

mmmmm... that blue is delicious

Morning glorys seem to flower all by themself.
Only time i have seen some morning glorys not flower was one year when my mother grew them.
They did grow very very good but no flowers.
I think she got 1 or 2, that was all.
She told me she had over fertilized them and this was the reason they grew so good and not produced any flowers.
So take it slow with the fertilizers and you should be good.
I have beatiful blue ones flowering right now, they sure are magical...
