Organic Winter Bloomsdale Spinach

Spinacia oleracea

Packet contains 4 grams (~280 seeds)

This is a winter-hardy version of Bloomsdale, the most popular and widely available open-pollinated spinach. The deeply-savoyed, dark green, leaves are sweet, tender and fleshy with a rich flavor.  Ideal for fall or early spring plantings.  This cool-loving variety will bolt in heat or long days. 

Growing Information

Days to harvest: 47.  Pick large leaves often to increase productivity.  

Fertility: Benefits from heavy feeding until plants approach harvestable age, at which point it becomes detrimental. 

Optimal soil temperature for germination: 45-65 F (min 35, max 85)

Days to germination: 5-25 (slower in cooler soil)

Sowing rate: One ounce plants 120-200 feet.  Crowding will induce premature bolting.

Planting Tips for Heirloom Organic Spinach:

Spinach is a cool weather crop and can either be planted in spring or fall.  For a spring crop, be sure to start these vegetable seeds indoors 6-8 weeks before the last frost date so that they can be transplanted in very early spring.  For a fall harvest, these heirloom seeds can be directly sown.  For best results it is very important to keep soil evenly moist with regular light waterings. 

When direct seeding, you should plant these organic heirloom seeds 1-2" apart.  Once they have shown several true leaves and are about 4" tall, you should then thin to final spacing.  For continual harvests, stagger plantings every 2-3 weeks for delicous spinach all season long.

Seeding Rate: 32,000 plants/acre, aproximately 2 lb.

Organic Heirloom seeds are hardy but always take care with your garden seeds to give them the appropriate amount of moisture - not letting the vegetable seeds dry out prematurely or overwatering and possibly having them rot.
