New Zealand is not a true spinach, but can be used in just the same way
and is more resistant than regular spinach to bolting during the hot summer
months! This variety actually thrives in hot weather. Plants are large and hardy,
and leaves are small and fleshy. High in vitamin content. Average: 65 days.
Detailed planting instructions:
As soon as you can work the soil in spring, sow seed ½ inch deep, 1
inch apart in rows 12 to 18 inches apart (or broadcast seed across a
wider area). Thin to 2 inch to 6 inch spacings. Closer spacings can stress
plants and cause them to go to seed (bolt) sooner.
Early planting is critical as dry soil, heat and
lengthening days also encourage bolting. Later plantings benefit from
some light shade from other crops. Follow early plantings with
warm-season crops such as tomatoes or beans.
Make succession plantings every week or two until
average last frost date. Use bolt-resistant varieties for later
plantings. Sow again in mid- to late summer for fall harvest. Seeds do
not germinate well in warm soil, so increase seeding rate to
compensate. Or pre-germinate seeds by placing them between sheets of
moist paper towel in a plastic bag and refrigerating until they sprout.
Spinach seedlings are difficult to transplant. For
spring crops, start inside only if your garden stays too wet in spring
to allow direct seeding. Start transplants inside about 3 to 6 weeks
before last frost.
Spinach is shallow-rooted and requires consistent
moisture to prevent bolting. Water to keep soil moist. Mulch after
plants are well established to maintain moisture and suppress weeks.
Use floating row covers to prevent insect damage.
Do not over fertilize with nitrogen. Only apply
supplemental fertilizer if leaves are pale green. Add lime to make sure
pH is at least 6.0. You should suspect that your soil is too acid if
germination is poor and leaf tips and margins are yellow or brown.
Plant in fall and mulch heavily for early spring crop.
Spinach is ready for use as
soon as it is edible size and it must be harvested before there is
extensive yellowing, breakage and other leaf deterioration or the
development of seed-stalks. Spinach for market is usually cut below the
crown with a knife, taking care to keep the plants clean and to prevent
undue breakage or bruising of the leaves. Spinach should be sorted to
remove all yellow or damaged leaves before packing into baskets. If
spinach is slightly wilted when packed, it will be less subject to
breakage. Usually, spinach is washed, repacked, and iced at a central
packing shed if it is to be shipped.
Wind pollinated. Spinach varieties must be isolated by 1/4 mile to
prevent cross pollination by wind. Physical barriers such as tree lines,
buildings or woods may make it possible to use a shorter distance.
Allow plants to bolt and set seed. Some staking may be necessary as
plants may reach 3' in height. When seeds are dry, harvest the entire
plant and thresh on a tarp. A 1/2 " screen on top of a 1/4" and 1/8" is
helpful for cleaning. Spinach seed remains viable for 3-5 years under
cool and dry storage conditions.
