What You’ll Learn
What Is Spinach?
Spinach , Spinacia oleracea , is an annual flowering vegetable in the Amaranthaceae ( amaranth ) kinsperson and is touch on tobeetsand quinoa .
maturate for its mildly flavored leaves , spinach plant is eaten fresh in salad , sweet talker , and wraps , sauteed or steamed as a side ravisher , or added into recipes like lasagna , soup , and stews .
And it ’s easily preserved by canning , dehydrating , or freeze .
Baby spinach plant folio are typically used raw while larger mature leave are most often manipulate .
full grown , the plant reach a height of eight to 12 column inch , and the simple leaves are elliptic to triangular in shape .
If spinach plants are allowed to blossom , the small , gullible - yellow flowers are n’t all that appealing to pollinator and the wind circularize the tiny pollen particles for reproduction .
After pollination , small-scale , hard fruit clusters form , containing several seed per cluster .
A cool - season vegetable , spinach can winter in meek mood , and successive planting cater a steady supplying of leaves almost all year . Plants are typically hardy in USDA Zones 5 to 9 .
Spinach come from a single species separate into three basal varieties of savoy , semi - savoy , and flat - leafed types .
Savoy spinach kind are low - growing with highly crinkled , curl leaves and this is the most productive case . They also have the undecomposed cold electrical resistance .
Semi - savoy types are grandiloquent and the leaves are less crinkled , making them sluttish to pick and lap . They also have the good disease and bolt immunity , fix them the most pop for home gardeners .
Flat - leafed smorgasbord have the smoothest leaves , make them the easiest to clean , and are the first option for commercially canned and frozen intersection .
deep in a variety of nutrient , spinach plant is abundant in antioxidants such as xanthophyl , kaempferol , natural nitrates , quercetin , and zeaxanthin , plus vitamins A , C , K , and folate , and minerals like calcium , iron , atomic number 25 , and Mg .
The leave are also high in indissoluble fibre and modest in carbohydrates with few Calorie .
However , spinach also take gamey level of oxalate which are harmless to most folks but can contribute to the establishment of oxalate kidney stones .
Cooking the leaf is an prosperous path to contract the amount of oxalates if this is a concern .
Cultivation and History
aboriginal to part of the Middle East , spinach plant was late in spread into other polish , with no references to its cultivation in the archive of ancient Greece and Rome .
historian believe it was comport west into Europe by the Moors via the Iberian Peninsula , and at the same prison term , traveled eastwards into China and India .
The oldest write records are from the fourth century CE in Mesopotamia and in the eleventh century CE in Spain .
After spreading through Europe , spinach make it in North America in the early 1800s .
Spinach Propagation
Spinach is easily propagated by source . As it pullulate in cool temperatures between 45 and 68 ° F , it is most often direct sown .
But seeds can bestarted indoorsand transplanted out if handle with care – more on how to do that in a bit .
Direct Sowing
Seeds can be direct inseminate in bounce four to eight week before your last frost date , or when soil temperatures stay above 40 ° atomic number 9 .
For fall sowing , look until the filth temperature cool to 70 ° F , or six to eight weeks before your average first freeze date .
set up the soil by enrich it with plenty of constitutive material likecompostor aged manure and loosen it to a profundity of 12 to 18 inches to accommodate the plants ’ farsighted taproot .
Sow spinach seeds half an inch deep and two inches apart . Cover the seeds with stain and house lightly in place .
Water gently and keep the ground lightly moist .
Seeds germinate in five to 21 days and have a viable shelf life of two to four old age .
repetition inseminate every three to four weeks until mid - May or when filth temperature reach 70 ° F for a continuous crop .
If set in early spring , it can be good to protect seedlings for a few week with sheets of clear charge plate robe over hoop .
This make a glasshouse - like effect that encourages foliage growth and keep root price from buildups of chalk or C. P. Snow and heavy pelting . On days of light rain , hit the plastic to give the soil a undecomposed sousing .
Start Seeds Indoors
Although spinach has a reputation of being difficult to transplant , small seedlings can be successfully relocate .
However , once the taproot embark on develop , plants can struggle with being moved .
Four to eight weeks before your last average frost day of the month , fill flat or trays with a seed - starting admixture . Sow seed in row half an column inch deep and two inches apart .
Cover the seeds with dirt and water lightly , keeping the soil moist but not wet until germination .
Place in a cool room with temperature between 50 and 70 ° F in lustrous but collateral lighter .
Transplant out when seedlings are two or three column inch tall .
How to Grow Spinach
For the best productivity , spinach ask well - drain grease with a loamy or sandy loam makeup and a more or less acidulous to neutral pH of 6.5 to 7.0 .
Plant in full Dominicus in spring and fall or in clean shade during the warmer months .
organise and loosen the soil in bottom and container as outline in the Direct Sowing incision above and constitute in rows 12 to 18 inches apart .
Spinacia oleracea plant life are heavy feeders and benefit from soil that ’s generously enriched with alfalfa meal , compost , or of age manure . Apply alfalfa meal as per package instructions and compost or manure at the rate of one pound per five straight animal foot .
If needed , commix in some gritty material like landscape sand or stone chips to ensure well - draining soil to debar progeny like root hogwash .
When plants are two inches tall , thin to four to six inches aside . cutting is important to prevent scrubby ontogenesis and early run off .
Keep their growing geographical zone weed detached . The farsighted taproots also form branch of shallower , fibrous root that do n’t compete well with weeds .
Once plants are four to six inch tall , lie down a two - column inch layer of light - emblazon mulch like shredded leaves or straw to keep the roots cool and keep back moisture .
Water on a regular basis , providingone to two inches of water per hebdomad .
After plant are four in tall , side wearing apparel every three or four weeks with light applications of a N - rich fertilizer , carry care to prevent the fertiliser from coming in contact with the stem to prevent burning .
Commercial fertilizers are labeled with a ratio of N to potassium and phosphorus , or NPK – look for ones that have a high first number to encourage leafage growth .

For a recollective time of year and abundant takings , sow small batches of seed regularly and harvest as a cut - and - get - again crop – each sowing will furnish several taking .
Once the spinach plants flower , the flavors diminish and plants can be removed and composted if they ’re detached of pest and disease .
In area with mild winter , inseminate a stalwart miscellany in late summer andgrow in a cold frameor protect plants with cloche orfloating quarrel coverfabric before the first frost .
Harvest gently over winter then remove covers in outflow once soil temperature reach 40 ° F – development is rapid once the years commence to lengthen , typically in mid - February .
Container Growth
For growing spinach plant in pots and planters , utilise container at least 18 inches deep to provide the longsighted taproots way to develop . They also need to have drainage holes to prevent wet dirt .
I like to dwell down a layer of porous material over the drainage holes to keep the piss moving freely out of the soil , and habituate drainage materials such as broken clayware or pebble .
meet pots with a humus - rich , arenaceous soil then sow in as outlined above in our instruction manual for verbatim sowing .
Provide one to two inch of water per week , more in red-hot weather , and endeavour to keep the filth lightly moist . Add a light - colored mulch to keep roots cool and the soil moist .
fecundate with a nitrogen - deep formula every three weeks .

Some fungal infections like white-hot rust fungus are pass around by insects and sprinkle water . Avoid overhead watering and ascendance disease - spread worm such as aphids .
Harvesting
For tender babe greenness , you’re able to start picking when the leaves are two or three inches long , snipping them from the tabu root .
Harvesting mature foliage is done in the same manner but wait until leaves are at least four inch in length .
Do not take away more than 50 percent of the leaf at any one time to encourage plants to produce more leaves , which can be pickeduntil the plants bolt and set forth to blossom .
To harvest a ripe flora , simply cut the intact works just above the territory line .
washout exit exhaustively in cool running water before consuming – the savoy cabbage and semi - savoy types tend to ensnare soil in the furrow .
Preserving
After wash , dispatch supererogatory water with a whirl in a salad thread maker or apply paper towel to gently dab the leaves to exhaustively absorb wet , then shop as desire .
Fresh
To store invigorated leaves , place in an airtight storage container or a nil top charge plate bag and keep in the crisper drawer of the icebox for up to 10 days .
Dehydrated
murder stems and distribute washed and dry leaves equally on dehydrator trays – a little overlap is fine but avoid thick clumps .
determine the temperature to your building block ’s low setting and dry for two to six hour , bet on the temperature and how wet the leaves were , or until they ’re completely ironical and crispy .
dispatch the leaves and cool down thoroughly before salt away in a jar with a tight meet lid in a cool , dark cupboard .
dry spinach has a shelf life story of one to two years when stored right .
Frozen
To freeze whole leaf , after wash and drying , plainly pack loose leaves into a zip top freezer bag . thrust out as much air as potential before seal then freeze .
When thawed , the whole leaves take on a blue color and limp texture but still have plenty of savor for dishes like soup and sweat .
And spinach can also be freeze in a puree .
Process whole leaves in a blender or food processor with a duet of free fall of urine and blitz until they ’re melt off .
smooch the puree into ice third power trays and freeze for three or four hours before transferring to freezer udder . constrict out as much air as possible before seal the bag .
frosty leaves and puree keep in the deep freezer for up to one class .
Canned
To can fresh leaves , first cut out problematic stems and costa then blanch in a steamer basket for three or four minutes , or just until they ’re softly wilted .
In clean , sterile quart shock , add together one - half teaspoon of salt if desired .
Fill the jar slackly with blanched leaves then add stewing water , leave one inch of dynamic headroom .
