Listeners may remember Meg Cowden of SeedtoFork.com from a previous episode on early seed starting.  She's back to talk about succession planting and her new book, Plant Grow Harvest Repeat (Timber Press, 2022).  Meg's book is filled with charts, plant lists, solid advice  and inspiration for any gardener who wants to grow an abundant food and fruit garden, with plenty of flowers as well. We talk about the importance of starting seeds over a longer stretch (always be sowing is Meg's mantra), learning garden lessons from the forests and prairies around us, managing soil health and insects, and ways to get the most from our food gardens through interplanting and other techniques. I also confess my absolute failure growing Brassicas, and Meg offers her secrets to growing huge harvests of broccoli, cabbage and more.

My guest is Melissa Wilsford of Rustic Hills Garden Co., a landscaping firm based in the Twin Cities, that specializes in creating edible landscapes.
