Giant Noble Spinach is an heirloom variety of spinach that was introduced in 1926. With its smooth, deep-green leaves, this spinach variety is a little sweeter than most others. It’s also easy to grow with minimal pest or disease issues. Giant Noble Spinach grows quickly and does not bolt as easily as other spinach varieties, so you can harvest it longer with less reseeding. Cut and use the leaves at any stage in their lifecycle, as they grow up to 20 inches long if given the proper environment.
The culinary uses for Giant Noble Spinach are abundant. Use raw when the leaves are very young for a baby spinach or allow to fully mature. You can also cook this variety by sautéing or steaming, in soups or stews, dips, and pastas. Try frying Large Red Cherry Tomatoes in salt & olive oil with Giant Noble Spinach for a deliciously simple side dish.

Start seeds indoors 2 weeks before your last local frost date, in cell trays with 1 to 2 seeds per cell.
Keep the soil moist and germination will occur in 8 to 12 days.
Once the first set of true leaves show, thin them to one seedling per cell.
When they are 3 inches tall, transplant the seedlings into the garden beds or large pots, buried in soil to the base of the stem, spacing the plants 5 to 8 inches apart.
If direct seeding spinach outdoors, plant seed 1/2 inch deep and 2 inches apart.
Once they get to be a few inches tall and show their true leaves, thin them out so they are spaced 5 to 8 inches apart.
If you plant spinach in successive plantings, with 12 to 18 days in between, you will have an extended overlapping harvest without the wait for the plants to mature.
You can start spinach seeds in large pots if you plan to grow them entirely in pots.
If you want to grow spinach during the hottest weeks of summer, partial shaded areas or additional shade cloth can, to an extent, help prevent bolting cause by hot weather.
Spinach grows best in loose, fertile soil with good drainage and a pH between 6.5 – 7.0; adding compost to the soil prior to planting will help provide essential nutrients and improve drainage.
To prevent summer bolting, stop planting one month before the hottest summer temperatures start.
Plant fall-harvested spinach towards the end of summer so it reaches maturity by late fall, when the air is cool, but not yet below 40°F.
Begin harvesting spinach leaves when they reach the desired size, typically around 4-6 inches long, or by harvesting the entire plant at full maturity between 40 and 50 days
Use scissors or a sharp knife to cut the outer leaves, leaving the inner leaves to continue growing.
Harvest spinach regularly to encourage continuous production throughout the growing season. Avoid letting the plants bolt, as the leaves become bitter once the plant starts to flower.
