they may have been stressed from too much water ... so you dug them up to change the soil??? .. stressing them even more???

you might be trying to love them to death ...

plant a few more seeds if you can ...

is it spring or fall in Malaysia???

what is the other plant in the pot ... or are those just sticks for the MG?

did you harden them off .. moving them from inside to outside.. for a week or so.. before they went into sun???.. that first transplant was also a stress ...

ken

its always summer in Malaysia, yup those are just sticks.
so you mean i should move them to outdoor but shaded place for a week, then only expose them to direct sunlight?

Thank you!

I think they were stress while growing inside...the stems are very long and thin, probably not enough light for seedlings. I would just put a few more seeds in that pot, once they germinate, thin out the ones that are weak and spindly.

Yes, MG do well in direct sun. . . but when it gets too hot the flower closes. (I think thats why) maybe they close later in the day because they are MORNING glories. . . I grow mine in full sun until about 1 PM then they are in bright shade and this particular spot seems to make them happy, the flower doesnt close. I don't start them in pots, I simply poke em in the ground a few inches. I do this as soon as the ground thaws from cold winter. They are hardy lil buggers. I have new MG seedlings every year that made it thru our winters and grew beautifully.

I agree they look a little stressed from being grown inside (not enough light) the transplant stressed them and now a shock due to the direct sunlight. If you do plant more seeds they will live happy in with the weak ones. Im guessing in due time you wont even know which ones were suffering.

Welcome to the world of gardening AKA trial and error. Good luck, show us pictures when they bloom for you.

If you put them out in full sun in their current weakened condition it will be the end for them.Since you are living in Malaysia wouldn't it be a lot easier and faster to start them in a pot or in the ground outside? They would grow much faster than your sick ones did and no need to harden them off.

Thank you all for the tips! I tried to put them outdoor but under the roof. They've recovered and growing very fast! I've put them next to the fence so they'll climb there and hopefully a picture of them blooming soon hehe!

I like a story with a happy ending.
