I was thinking of planting some sweet peas in pots beside a SE wall of
my house and training them up the wall on some sort of wire/string
arrangement. The color and aroma people talk about seem heavenly. Since
I have no idea what I'm doing, I was hoping for a few hints? Size of
pots? Number of plants per pot? Best way to train them up the wall?
What to fill the pots with?

Since the patio comes all the way up to the house, I'm looking for some
way to brighten things up a bit without taking a sledge hammer to the
cement to get to the soil.

TIA,
Rob
