|Can Artichokes be successfully grown in zone 4?
What kind of soil conditions are required?
|The problem with growing Globe Artichokes in our climate is that they don't really yield until the second year. They are normally grown as perennials in Zones 8-9. They can be grown in Zones 5-7 but they need really SPECIAL winter protection. Theywould need to be cut back in late fall and protected over the winter with an inverted basket or box and a deep mulch.
Soil must be rich, well drained and of near-neutral pH. Seeds should be started indoors and transplanted in late spring when the soil is thoroughly warmed. Seedlings should be planted about 2 feet apart in the row and about 3 feet between rows. They need lots of compost or manure. They also require deep watering.
