How to Grow Correnta Spinach

Spinach (Spinacia oleracea) grows primarily as a cool-weather crop for spring and fall harvesting. Many spinach cultivars, however, bolt, or stop producing foliage and start producing flowers and seeds as daylight hours lengthen and temperatures rise. Their leaves become bitter and tough. A few slow-to-bolt varieties, however, offer gardeners the opportunity for fresh spinach from early summer into early autumn. Among them is Correnta, a smooth-leaved spinach from the Netherlands' Royal Sluis breeders. This 1978 introduction's deep-green, oval foliage also has good resistance to downy mildew.

Instructions

    • 1

      Choose a well-drained planting site in full sun to partial shade.

    • 2

      Prepare your site. Spinach loves high-nitrogen, organically rich soils. Use the hoe to work your compost and cottonseed meal or other amendments into the soil prior to planting.

    • 3

      Plant your Correnta spinach at two-week intervals. Begin in late spring and continue until midsummer. Planting at intervals ensures a continuing supply of spinach through the summer.

    • 4

      Space your planting rows 1 to 1 1/2 feet apart. Plant Correnta seeds 1/4 inch to 1/2 inch deep and 1 inch apart. Set started plants 12 to 18 inches apart unless their planting labels suggest otherwise. (

    • 5

      Water the soil with the hose or watering can often enough to keep it moist until the seedlings emerge. Water seedlings and started plants at the rate of 1 inch every week to 10 days during dry weather.

    • 6

      Use the stem clippers to remove stems that start shooting up from the center of your Correnta spinach leaves. They are most likely to appear on older plants. Preventing them from flowering and setting seed extends your harvest of edible foliage.

    • 7

      Harvest your Correnta spinach when its leaves are young for maximum tenderness and flavor leaves. Snip off the rosette of five or six leaves with the stem clippers. For a continuing harvest, remove the outer three leaves. Let the smaller, inner ones continue to mature.
