They came up strong and are growing well.
These leeks need really rich soil to grow to 2 or 3 inches but even if smaller have a great mild taste. Also if you let a few mature for seeds they also produce offsets (look like cocktail onions before they sprout). These will give you large leeks faster than you can get from seed. Have to dig deep to find them or water really well just as it cools in fall and they'll sprout & be easier to find (I'm zone 9a so grow them easily all winter).
I grew these under row cover because we now have Allium moths in Vermont. they were beautiful and hardy and vigorous and I felt like I had cracked the code on how to grow moth free leeks... then... I went on vacation and the row cover blew off in a storm. came back and the leeks looked okay so I put the cover back... one week later I checked them and they were destroyed. You know that feeling... wishing winter would come and "send all the bugs back to **** where they belong". I salvaged part of the white ends and put them in the freezer. Next year... I will do it all over again, but this time... I will check them more frequently and get some better clamps (and maybe I won't go on vacation in the summer!!! )
