Kabocha Squash ‘ Cucurbita maxima ’ Plant Overview
History and Cultivation
At first glance , kabocha looks like a funky , warty green pumpkin vine . As a varietal of theCucurbita maximaspecies , it is closely relate to ‘ Hubbard ’ squash and butternut , but its unequaled culinary and farming chronicle has earned kabocha its own class . This scrumptiously rich squash rackets has a hard exterior with bumpy dark-green or orangish skin and light green or ashen banding . When cook , the vibrant orange interior has a chestnut tree - like texture and a flossy soupiness .
Best of all , it has along storage time period when it ’s cure properly . Perhaps this is why Japanese pumpkin have become a stylemark of Asian culinary art . The works ’s fat history furnish many clues on cultivating , storing , and fudge it !
What is Kabocha Squash?
Kabocha squeeze , also known as kabocha pumpkin or Japanese pumpkin , is avariety of wintertime squashrevered for its velvety , fluffy texture and exceptionally sweet flavour . Many describe it asa cross between odorous potatoes , pumpkins , and butternut squash .
Kabocha has vivacious orangeness or green skin , feeble stripe , and a bumpy or warty grain . The flesh is undimmed yellow-bellied or orangish and is delectable when ridicule , boil , steamer , or pureed .
The Japanese wordkabochaliterally translates to “ Nipponese pumpkin . ” Some say the full term comes from the Japanese origin wordkabu , which intend “ turnip , ” a reference to the squash ’s hearty , starchy keep . The crop is widely used in traditional dishes , likeKabocha no nimono , a simmered soy sauce - flavor side looker serve virtually everywhere in Japan . In the KoreanDanhobakbap , squash cut are engorge with sweet fateful rice , peas , nuts , and chili .

Where Does Kabocha Squash Originate?
Despite its popularity in Nipponese and Korean cuisines , kabocha squash originated in Central and South America with the relaxation of the squash family cousins . When the Portuguese colonise Brazil , they collected and enthrall many cucurbit to Asia , let in the ascendant of this wintertime mash variety .
The first seeds reportedly arrive in Japan in the sixteenth hundred from Cambodia . Because it issuited to cool climates than other squashes , it became especially pop in Hokkaido , a northern region of Japan .
What Does Kabocha Squash Taste Like?
The unique flavor and grain of kabocha tastes like acombination of butternut squash and fresh potato , like anultra - sweet-smelling creamy pumpkin . It can be used in sweet and savoury beauty , from pies to roasts to soup to tempura .
Propagation
Like most winter squash , kabocha is implant in late spring or former summertime when the atmospheric condition has thoroughly settled and all chances of frost have passed . This cucurbit is tender to cold weather and willnot tolerate temperatures under 55 ° F . you’re able to propagate it by direct seeding , farm your own starts , or purchase glasshouse seedling .
Direct Seed
Squash does best when sown directly in the garden soil . These frost - tender vine have thin taproot that prefer to get established in property . However , this can be challenging for northern growers or anyone with erratic spring weather .
The soil temperature must be at least 70 ° farad , rather closer to 80 - 90 ° F . Use a grease thermometer investigation to check out before planting . Raised bottom ignite up fasterthan in - reason layer , so consider farm your squash on a mound or lasagna - style bed .
Move any mulch out of the mode so the Lord’s Day can promptly warm the soil . Straw mulch is awing , but it can slow down the thaw of your land in the spring . A black tarpaulin or clear plastic can also help heat up the seed bed more apace .

Sow sow ½ to 1 ” deep , or at more or less a deepness that valuate twice the dimensions of the seed itself . I like to inseminate two seeds per hole at 18 - 48 ” apart in rows 6 - 12 foot asunder . shaggy-coated and shortsighted - vine variety typicallyneed 6 ’ space between rows , but farseeing vines may want up to 12 ’ to make maximal potential .
The in - row spacing varies based on the yield size of it :
The seeds take 7 - 12 twenty-four hour period to emerge . After germination , thin the seedling to 1 plant per space interval . Double - check your seed packet boat for recommended spacing , as some kombucha diverseness are more compact and can be grown nigher together .

Immediately irrigate the come and cover them withfloating row fabric . dustup cover dramaticallyimproves early on squash success and alleviates transplantation seismic disturbance .
It moderates the microclimate near the grunge , keeping the seedlings warmer and buffering against nighttime temperature fall . It also physically excludes pests so your babe plants can get established in peace . Do n’t forget to secure it with sandbags or fluid rocks .
Start Indoors
Cold clime warrant transfer your squash because the spring weather is too unpredictable . Kabocha does n’t mind being transplanted as long as you handle them very cautiously . start indoors allows you to apply aseed heating matto encourage robust other growth .
Ensure plenty of bright sunlight from a Dixieland - facing windowsill , greenhouse , or a grow ignitor . The ambient temperature should bearound 70 ° F or way temperaturein your home .
The skillful time to seed indoors is justthree weeks before transplanting . I care to inseminate squeeze seed on the last frost appointment , take up the weather is thoroughly settled three week later . wintertime squash racquets should not be started indoors too soon . The seedlings establish apace and may suffer if they look in their pots for too long before the weather settle out of doors .

Fill 3 - 4 ” pots with a timbre well - drained potting mixing . Sow 2 - 3 seeds per container and thin one plant each after germination . Grow at a consistent 70 - 75 ° F ambient air temperature . sustain consistent wet without ready the soil soggy .
temper off the plants 4 - 7 day before transplanting . you may move them from your greenhouse or windowsill to a protected terrace or porch . Cover with row fabric if the nights are still coolheaded . Allowing the plants to acclimatize to abrasive outside condition dramaticallyreduces the risk of transplantation electrical shock .
Nursery Seedlings
feel kabocha in standard nurseries may be hard , but many strong point organic veggie farmers grow the starts and sell them at spring plant sales . If you need to transplant from an established seedling , be very selective about which baby plants you take home .
Here ’s what to search for when purchasing squash transplanting :
think that cucurbit - folk crop arevery sensitive to transplantbecause they have tender taproot . While it ’s utterly possible to grow successful squash crops from transplanted seedlings , you want to choose the strongest and most vigorous plant and handle them carefully . Otherwise , you ’ll have sad , wilted plants that fail to take off in the belated give properly .

Planting
After seeds are established , planting is a zephyr . As long as you thoroughly aerate the ground and carefully handle the seedling , your kabocha should take off with exponential growth !
The most significant thing to do ismonitor the weather . Do n’t run a risk losing your winter squash by transplanting too soon . Nighttime temperatures should be dependably above 55 ° atomic number 9 . Anything stale warrants the usance of a low tunnel or row screening .
How to Transplant
transplantation kabocha just like any cucurbit : with extreme care ! Cucumbers , melons , mash , and Cucurbita pepo all have sensitive taproots . If you swot seedlings into the soil , you risk disturbing their antecedent zones and stunting or kill them .
First , verify the soil is thoroughly aerated . liberally rectify with compost and broad ramification to lift any compaction . expend a shovel orhori hori knifeto make a muddle twice as deep and spacious as the seedling root ball .
Gently knead the bottom of the container to tease the roots . Grasp the plant from the cornerstone of its stem turn and wobble it out of the can . Place in the hole and cautiously hold it up so the radical stays above ground .

The soil level should remain the same as when it was in the pot . Backfill the stay ground under and around the flora until it is absolutely tucked in . Give it a gentle imperativeness , but do n’t tamp down the soil and compress it . To belittle transplant shock , water in with a dilute kelp root and a generous amount of irrigation .
Spacing
As with direct seeding , transplanted kabocha must be space jolly far apart . The exact spatial arrangement depends on the smorgasbord . mark your seminal fluid packet and , when in doubt , widen the spacing . plant life should have too much room rather than too little .
I like to maturate small‘Kurinishiki’kabocha inmounded rows 4 fundament asunder with plant 18 - 24 ” asunder . large fruited varieties need more elbow room to sprawl . If you survive in a humid climate where squelch on a regular basis gets pathologic , wider spacing is the best way to assure airflow between the vines .
How to Grow
Kabochathrives in the same conditionsas your other summer and winter crush crop . The plants will yield copiously as long as you provide ample sunlight , plentiful grease , and plenty of water .
Light
Squash require full sun to raise healthy fruit . Plant in an surface area that receives at least 6 - 8 hour of direct sunlight daily . These vinesdo not tolerate subtlety wellunless you live in a southern clime where they require protective covering from extreme good afternoon heat .
forfend planting in the phantasma of trees or other structures . You should also avoid growing with tall companion plants . Though some have succeeded with “ three sis ” ( clavus , edible bean , and squash ) interplanting , kabocha does best when it can vine out in the open .
Water
Consistent wet is all-important for rich Japanese pumpkins . The stain should be regularly moist but never waterlogged . The plants enjoy deep watering at least once each week or more frequently during juiceless flow .
Do not irrigate kabocha from above , which can take to fungal diseases like powdery mildew . You do n’t require moisture to sit on the foliage open . Instead , use drip irrigation or downpour hosepipe to irrigate from the base .
call up that plantsenjoy less frequent , deeper wateringrather than constant shallow tearing . Allow the irrigation to run for an 60 minutes or so , then adhere your fingerbreadth in the soil to verify if the water has reach 4 - 6 ” down . These plants have extensive root system with thick taproots and many shallow lateral roots . Always guarantee that water reaches the lower soil level but check that that it is n’t pooling up or causing squashy conditions .

Soil
It ’s best to grow kabocha in advance bed or mounds . Soil promote off the earth warm up up more quickly because a greater surface domain is exposed to the Lord’s Day . Moreover , the raised beds encourage faster drainage to prevent waterlogged or soggy circumstance . A lasagna - garden - style bed ( layers of sticks , straw , leaves , grass clippings , compost , and topsoil ) works incredibly well for this flora .
Your classic loamy , well - drained , compost - fertile garden soil is ideal for this winter crush . A slightly acidic pHbetween 6.0 and 6.8is standard . Before planting , I always amend my squash racquets bottom with generous amounts of well - rotted compost or aged manure . Organic matter will meliorate rankness , drainage , and urine - hold capacitance on hot , dry summer days .
Mulch winter squash generously to deoxidise weeds and conserve urine . Straw ordried deciduous leaveshelp keep the yield off the soil surface , reducing the risk of rotting . I disseminate a 1 - 2 ” thick level of mulch a workweek or so after transplanting . nullify spread out the mulch too closelipped to the base of the plant , as you desire raft of airflow by the stem .

Climate and Temperature
This is a warm - season harvest that demands temperatures above 55 - 60 ° F . The ideal conditions is 70 - 85 ° fluorine , but you’re able to habituate season elongation like dustup covers to keep the plants cozier into the crepuscule . Kabocha is a long - maturity crop that takes 90 - 120 days to get on .
Zones 5 - 11 typically have no problem produce this autumn pumpkin out in the elements without protective cover . Ensure your regionhas enough icing - free grow days . Otherwise , you ’ll have to transplant or apply low tunnel to ensure the plant can bring out mature fruit before cold weather arrives .
As we ’ve mention several times , words natural covering is crucial for this crop because it keep the tender plants ardent and protect from cuss . However , youMUST remove the row covers once the plant life begin blossom !

If you leave behind the covers on , pollenation will be seriously reduced , and you may not get any Japanese pumpkin . Squash is predominantly pollinated by bee , and these buzzing pollinators will have problem access your crop if the run-in fabric stays in position for too long .
you’re able to hand - pollinate squash racquets if you ’re dish out with important pest insistence and require to keep the row covers in office , but do n’t forget to check every twenty-four hour period to see which flowers are in need of pollination .
Fertilizing
Squash is a arduous feeder that needs batch of richness to fire the growth of massive vines and pumpkin production . Before planting , comprise 1 - 2 ” of compost . At the clock time of seeding or transplanting , bring a nice handful of all - intent granular fertilizer likeEspoma Bio - Tone Starter Plus Organic Plant Food . As the plants start flowering , side - dress with one more dose of balanced , all - design fertilizer likeEspoma Garden - Tone Organic Plant Foodor a seaweed - found liquid fertiliser .
invalidate over - inseminate squashbecause too much nitrogen can conduce to excessive foliage increase that may shrink yield production . Balanced , slow - release organic fertilizers are ideal . Balanced means that the three numbers on the fertilizer mail boat ( Nitrogen – Phosphorus – Potassium ) are fairly close together , such as 4 - 3 - 3 or 3 - 4 - 4
Maintenance
The only regular maintenance these plants expect for is unconstipated weeding . Squash do not support a raft of weed competition when they are young . luckily , as the plants mature , their large leaves of course shadow out many weeds .
Be very careful when hoeing or weeding near the plants so you do n’t damage the shallow antecedent and vine . mulch with straw or leaves importantly cuts down on weeding . well yet , examine no - till strategies toreduce your weed pressure .
If you hold up in a humid mood where plant are prone to disease , you may also want toprune away excess foliage to improve air circulation . Remove yellow , dying , or infect leaves pronto . Never leave alone squash debris in the field ; it can become a reservoir for pests and disease the following season .

Curing
When your kabocha squash has finally sized up into gorgeous orangeness or dark-green pumpkins , it ’s time to harvest and cure them ! Curing is simply put the freshly harvested yield in a ardent , dry billet for a specific duration of sentence .
The bring around process season the cutis toensure long - terminal figure storage through the winter . As squash therapeutic , their dough also become more concentrated because the moisture content is reduced . The outcome is a more flavorful culinary experience . If you do n’t cure your winter squash , it may not last as long in storage or smack as good in the kitchen .
To properly heal your squash :

Avoid exposing the squash rackets to direct sunlight because UV electron beam can scorch the fruits and cut the storage time . by rights cured kabocha can be stored for 3 - 4 calendar month or more !
Varieties
Kabocha is technically a whole category of Japanese squeeze that includes green and red ( orangeness ) varieties ofmany unlike sizes and specification .
This small-scale , honest mixed bag yields 3 - 4 Cypriot pound Japanese pumpkins with 4 - 12 ’ vines . The robust fruitsstore for up to 5 monthswhen properly cured .
The little premium 2 - 3 pound kombuchahas incredibly high fruit per works . You may only need a few industrial plant to keep you quenched all wintertime ! The store life and vibrant color are notably good than other kind .

A gorgeous recondite green personal - sized kabocha , ‘ Sweet Jade ’ isgreat for engorge . you’re able to use the skins as soup bowls with little to no purposeless fruit . They average a micro 1 - 2 pounds and work cracking for compact gardens .
The Graeco-Roman vermilion kabocha , these fruits are medium - sized with glowing , gorgeous tegument . This F1 hybridhas a superior appearance and eating quality . you’re able to eat the squash right at maturity ( even before curing ! ) The vines are short and vigorous .
Pests and Diseases
Like many cucurbits , this squelch issusceptible to the aggressive approach of aphids , cucumber mallet , and squash hemipteron . Powdery mildewand other disease can also assault the vine if stressed , overcrowded , or exposed to high humidity . Fortunately , there are easy ways to grapple with these issues organically , so you do n’t have to fall back to synthetic pesticides or fungicides .
Aphids
These little , soft - bodied insects exhaust just about everything in the garden . They can be green , yellow , or sinister and tend to cluster on the undersides of parting . You may notice a sticky sap that appeal ants .
To control them , spray a secure stream of water on your works to free the aphids . Do this in the morning so the squash has plenty of time to dry out in the sun . Use a diluted neem sprayto repel future infestations . Companion planting with marigolds , white alyssum , and yarrow can attract ladybugs and lacewings , natural marauder of aphids .
Cucumber Beetles
These little yellow - and - black striped or spotted beetle are a real pain in the neck for anyone who have intercourse cucumber - kinsperson crops . They attack cucumber vine , melon vine , zucchini , and winter squash with adequate vengeance , so it ’s good to keep these crops circulate out in different garden areas . They most commonly go for the leaves and flower blossoms of kabocha .
quarrel covers are your best protection , especially for new plants . you could handpick and down beetle . Diatomaceous earth is a natural powdery deterrent you could dust on leaf surfaces tokeep cucumber beetles aside .
Squash Bugs
These utter - looking brownish or gray flattened insects damage the leave and stems , causing wilt . If you acknowledge them around , hand remove and squash them ( no paronomasia intended).Neem oil and insecticidal soapcan ascendency terrible infestations , but rowing covers are a more reliable way to take out them from the harvest physically .
Powdery Mildew
This pesky powdery white flufftends to appear on squash rackets in midsummer and hang . This fungous disease enjoy lovingness and humidity , so circulation is a must to prevent infections . Properly space your plant and prune away any excess or dying foliage . Neem oil can be applied preventatively . Use an constituent pig fungicide as a last resort . Always abide by package instructions . ward off overhead irrigation at all monetary value , as this can help the rapid counterpane of the disease .
Downy Mildew
This fungus manifest as angulate , yellow spots on the top of leave of absence and grayish fluffy increase on the bottom . It canspread fairly apace in sozzled shape , which is why overhead irrigation is so defective for squash vine plants . Remove and put down affected leafage to preclude them from spreading . Never compost mould - infected plant ! bull - ground fungicides can be used as a last resort .
Bacterial Wilt
If your plant suddenly wilt and die , you may bedealing with bacterial wilt disease . Cucumber beetles often circulate this nasty disease . There is no therapeutic , so you must move out and destroy septic plants and practice rigorous crop rotation to keep this bacterial contagion at bay .
Plant Uses
Kabocha squash is a remarkably versatile constituent used in fresh and savoury dishes across many cuisine . The good ways to utilise these gastronome pumpkin admit :
The skin of kabocha isedible when cooked . you’re able to poke fun or steam the pumpkins whole and enjoy the tegument much like a Delicata squash vine . The beautiful orangish rinds are gorgeous in roast and add a courteous battery-acid of fibre .

Final Thoughts
candidly , I would n’t even trouble grow pumpkins anymore . Kabocha is just that respectable ! The headstone to success with this crop is growing in warm weather , provide plenty of moisture , and using course blanket during the former stages . However , do n’t bury toremove the covering once plants get flowering ! They need to be pollinate by bee to produce abundant squash vine !
