Beginners Gardening

I have been growing sunflowers all summer and I start them in a pot. Almost every time, they have a dangerously thin stem and they don’t produce as many leaves as they should. So every time I transplant them into my garden they just die out. What can I do to help prevent that?
They only grow to about a foot tall before dying. And, they get about 3-4" tall before getting their second pair of leaves. Most of the time, they just lean over too much which is how they die.

Im trying to re-design my garden but we are having really bad weather recently and its filled up the trenches i have dug for my new walls with rain. We have really bad drainage in the garden so its not draining away quickly. Can anyone suggest an inexpensive way to cover/protect the garden from the rain which would allow me to continue working in the garden at the same time?

My garden is 5m wide by 9m long (if that makes any difference?) I was going to nail polythene to the fences to cover the garden but i thought that might rip and blow away in the wind?! Any other ideas are most welcome! Thanks
Im redesigning the garden ie, building walls, changing levels etc, so it has to be something that will allow me to do this without the ground getting wet – like a gazebo or something.

going on vacation for a week.
