We've had good luck with flax seed, but the first time we planted it it didn't really take until the 2nd year. Now we bought more seeds to cover a VERY thistley-weedy area. When is the best time to sow the flax? Spring or Fall?
Technically, we are in Zone 4, BUT we have a micro-climate on our hill that pushes towards Zone 5 - call it Zone 4.5. It's high desert - meaning hot summers with cool nights; winters are cold -10 is not infrequent during mid-winter as a cold snap. I did say "desert" and flax doesn't require water as it grows wild in the hills here. Also we like to xeriscape as much as possible.
