Good idea to soak the seeds (but not absolutely necessary). We're waiting another two weeks- oodles of rain in our forecast for most of next week, then the weather warms up. Morning glories germinate quite quickly and they're not frost hardy. We don't grow sweet peas as Glyn is allergic to them but better to be safe than frostbitten!!
@kaigia. Sounds like we've planted the same thing and this also is my first year to use seeds, annuals, outside. I grow houseplants too and used some of my plants to make starts for outside. Anyway, nice to meet you! Oh, blue Morning Glory have come up and about 10 sweet pea seeds. No pink Morning Glory tho. Planted about 3 weeks ago. Bye for now!
