Since I live in zone 5a, I am going to start Morning Glory seeds in peat pots indoors at the beginning of April to later transfer outside (around late May) when the weather is warm enough. How large should the OUTSIDE flower pots (round) be in depth and dimension? I was also wondering if I could transplant them into RECTANGULAR planters? I intend to have the vines climb up 2 trellises that are 2 feet wide each and about 8-9 feet tall. One more question ... how far apart to plant the seedlings? Thanks for any info : - ))
