I read your article on the Dutchman's pipe. I have a very healthy plant that seems to thrive on neglect. When you say to start new, I would use the seeds. Are the seeds in the pipes?
The seed pods will form on the vine after the flowers have faded.

The seedlings have a very fragile stem and can't stay upright. Is it ok to let them lay flat on the soil? The plants are about 4 inches long and have 6 to 8 leaves. Not sure what is best for the plantlets.
Sorry, here is the article.

No, the seedlings should be upright, lying on the soil will likely lead to the loss of your seedlings.
This is likely do to lack of light.

I water my Dutchman pipe vine and I have new foliage but, the leaves are wilting. Why?
Check moisture levels; wilting could be lack of water or excess water.

How many hours of sunlight does this vine require? Would 4 hours suffice?
4 hours of sunlight should be just fine, though they can tolerate full sun. Shelter from wind and regular watering with a good loamy moist soil are key.

Six year old vine is planed in shaded area next to 6' lattice. Lower two feet of plant does not receive sun. Pant covers lattice and top portion of lattice receives more sun. Plant has never bloomed but grows has profusely. Many blosooms have formed the last three seasons but drop from their stems before flowering. Do I need to fertilize and if so what percentages and what time of year, or is plant in too much shade? I was told the plant would do well in partial shade when I made the purchase from the nursey about six years ago. When plant spill over lattice to neighbor's side it is exposed to the south and substantial sun.
