Harvesting Tips:
Harvest spinach before it starts putting up seed stalks, because it becomes tough and strong tasting.
Cut the whole plant straight across about 1/2" above the ground. If you start harvesting when the plants are very young and have only 5-6 leaves, they will grow a new set of leaves before going to seed. Long-standing variety may last longer. You may also clip off outer leaves and leave inner leaves to grow more.

Eating Tips:
Add to salads
Add to fruit shakes to make "green" smoothies

Preserving Tips:
Refrigerate
Wash and freeze in gallon size freezer bags
