I planted the Gigante D'Inverno Spinach early this Spring under rowcover. It is by far the biggest and best Spring sown spinach that I have ever grown. I did not expect it to do well in the Spring. Thought you might like to know this. I finished picking my Gigante spinach today.
... Everything I wrote last time is true but Gigante bolts quickly so pick it early before mid May. It's size and rapid growth make growing it under row cover or in a hoophouse worthwhile for early harvest of big spinach.
