What would cause newly repotted plants to die suddenly?

I purchased mini flower kits from buzzyseeds. They come with a mini pot, compressed dirt, and seeds. I planted them per the instructions and they began to sprout above the dirt within a week. Now they have gotten too big for the tiny pots. I transferred them to a slightly larger pot with Miracle Gro Moture Control Potting Soil. They were watered well, and seemed okay. It is now two days later and many of the shoots are slumped over. What did I do wrong? This is my first attempt at growing anything. The flowers are marigolds, daisies, and mini sunflowers each kind in their own pot, 10 seeds per pot.

What would cause newly repotted plants to die suddenly?
I%26#039;m not an expert but from my experience with repotting plants I can say it could be a number of things. Are they in a different location verses where you had the smaller pots? Too much sun too soon will do this as will temperature changes. If you went up to a much larger pot, some plants don%26#039;t like too much room too fast but I%26#039;m not sure about what you%26#039;ve planted. If the soil is too wet they will also wilt over.
Reply:when you repotted did you pull out the compressed soil with the root ball and put the whole thing in the new soil. Some plants have a little shock when transplanting but if you didn%26#039;t tear up the root ball it should perk back up.
Reply:Give them a few more days and they will perk up again. If you were pulled up by the roots i think you%26#039;d slump over too. Did you leave a ball of soil around the root? If not thats the trouble.
Reply:DO YOU SMOKE? We found that smokers can kill young plants and even gold fish, just by handling them. Nicotine is poisonous and touching small delicate things with Smokers hands will kill.
Reply:they may be in shock from the transfer. be careful not to over-water them and give them a few more days, even a week and a little TLC and they%26#039;ll snap back.
Reply:Often newly transplanted seedlings experience shock for a few days, but they soon catch up. As long as they aren%26#039;t turning mushy or yellow or brown and drying up, your plants are alive. Be sure they%26#039;re getting the light exposure suggested on the original packaging.





If the plants are turning mushy or the stems appear to be deteriorating at or near the dirt, they%26#039;ve been overwatered. There is nothing you can really do to reverse that. They will die.
