I have 2 sections of 4x4 bamboo fencing and would like to line window boxes in front of them and plants vines to cover it,my question is what vines can I plant I have morning glory,sweet pea,moonflower seeds will they work??? Thank you for your help

I don't see any problem except for the possible damage to your bamboo fence. Morning Glories at least really get wound up in their support at least mine have. I had a hanging basket with chain supports and the morning glory was really in there.

I grew morning glories and sweet peas in windowboxes on my deck railing last summer with trellises attached to the railing, and they were fine. The sweet peas didn't flower for very long, and the morning glories don't bloom here until the very end of summer (I'm also in NY), but you certainly can grow them that way.

Since I use these planters to provide some privacy on my deck, I am looking for vines that will have better leaves and flowers this year.

Any suggestions?

This site has a lot of information about vines on it.

You might find something that will fit here.

Scarlet runner beans, the flowers are beautiful and you get to eat the beans.

everybody
i have dwarf morning glories which cascade over the edge of the hanging basket they are in(you can purchase seed pack from home depot) they look nice hanging,sorry, cascading over the sides.
they dont require support-they are non climbing
