Hi. I have just cleared an area that recievs 3-6 hour of full sun. I want to plant some chard there. I live in the north east. I am planing to grow them in pots in this area. Can I plant the seeds now? Or did I wait too long? I hear they should be started 3 weeks before last frost then bring them outside. Any information would be good. I hear they go through the summer into late fall so I think I can but just want to hear some advice.
