Is it too late to plant morning glories or moon flowers?

Morning glories -- you've got plenty of time yet, and don't forget in September, before the first hard frost, they'll stay in bloom almost all day. Moon flowers....it may be tight. If you've got the seeds get them soaking right now. Get off the computer, get them in some warm water in a warm spot for 24-30 hours before planting to give them a boost.

get planting, with your climate you'll be picking flowers in a month, worst case you waste a few seeds. I am struggling in the height of summer its 50 degrees at the moment, no sun for two weeks.(u.k.) but mine are growing away.

dig a trench approximately 6 inched deep. soak seeds in one day and plant in trench approximately an inch deep, as they improve pull some dirt into the ditch so purely the right growth shows. try this till trench is finished
