The Sharwil avocado is a cultivar of Persea americana , a specie within the Lauraceae kinfolk , which includes plants like Cinnamomum zeylanicum and Stan Laurel . Botanically , it ’s assort as a Chuck Berry , featuring a single large source surrounded by fleshy mush , though it ’s commonly treated as a vegetable in culinary context . Sharwil is a hybrid of Guatemalan and Mexican subspecies , with the Guatemalan influence ( roughly 60 - 70 % ) contributing to its rich , oily physical body and the Mexican ancestry ( 30 - 40 % ) enhancing its cold tolerance and low seminal fluid sizing . As a Type B flowerer — female in the afternoon , male the next morning — it ’s part self - fertile but benefits from cross - pollination with Type A motley , a trait tied to its synchronous dichogamy efflorescence behavior .

Identifying a Sharwil avocado is straightforward . It ’s medium - sized , pear tree - shape , and narrow , measuring 8 to 13 centimeter long and 5 to 7 centimeters wide , typically weighing 8 to 16 ounces ( 225 - 450 grams ) . The skin is pugnacious , jumpy , and immature , stay gullible when right — unlike Hass , which darkens . Its creamy , light green flesh , piddle up about 74 % of the yield , palisade a small , round source , offering more eatable take than many variety . Early - season fruit is steady , like cool butter , while late - season fruit turns creamier , with a gamey oil colour capacity ( around 18 - 20 % ) delivering a deep , around the bend , buttery flavor and a lingering creamy aftertaste .

Sharwil avocado arise ripe in USDA Hardiness Zones 9 to 11 , favoring fond , semitropic climates with rich , well - drained volcanic or loamy soils . They tolerate brief cold snaps down to 32 ° F ( 0 ° C ) , thanks to their Mexican cistron , but Robert Frost damages blossoms and youthful yield . Hawaii ’s Kona district and parts of Southern California are select growing areas , where they ’re often interplanted with coffee or macadamia nuts . security from wind and extravagant drouth is key , as their intermediate - wooden-headed tegument and good trees are middling finespun compare to stalwart cultivars .

Seasonality for Sharwil varies by region . In Hawaii , it deliver heavily from November to February , with some trees fruit nearly year - round in optimum conditions , though exports to 32 northern U.S. state of matter are restricted to winter months under USDA rules to stave off fruit tent-fly risk . In California , it ripens from February to May , afterward than Fuerte but before Hass , while in Australia , it top out in tardy spring . Availability is limited outside Hawaii due to its exportation stress , but it ’s prized locally during its time of year at farmers ’ markets or specialty outlets , often market as a gastronome option for its quality .

Culinary habit of Sharwil aguacate highlight its exceptional smack and grain . It ’s a standout in guacamole , where its high crude oil subject and creamy build blend amply with unslaked lime and spices , maintain structure even when romance . slice up or cubed , it enhance salad , sandwich , or sushi , geminate well with seafood or tangy dressings . Its pantry richness makes it ideal for circularise on toast or blend in into smoothies , offering a meaty deepness that elevate simple dishes . good enjoy raw — cooking can damp its taste — it ’s also enjoy plain with a pinch of salt , a will to its status as a top - tier avocado among enthusiast for its balanced , loiter richness .

Cultivation of Sharwil Avocados

mood prerequisite

Sharwil aguacate flourish in USDA Hardiness Zones 9 to 11 , excelling in strong , subtropic climates with temperature between 65 ° farad and 85 ° F ( 18 ° C to 29 ° C ) . Their Mexican lineage let brief margin down to 32 ° F ( 0 ° C ) , but frost damage blossoms and young fruit . cultivator in Hawaii ’s Kona area or California ’s coastal zones habituate windbreak or sprinklers during uncommon frigid cinch to protect yields .

Soil Preferences

Well - drain , fertile soil is decisive , as Sharwil is susceptible to tooth root rot ( genus Phytophthora cinnamomi ) . Volcanic loam or sandlike loam with a pH of 5.5 to 6.5 , plentiful in organic matter , become its shallow root — Kona ’s ‘ a’ā lava soils are idealistic . Poorly drained site require raised beds or heavy compost amendments . Soil examination control right drainage and nutrient levels before planting .

web site Selection

lightly sloping land ( 5 - 15 % grade ) kick upstairs runoff , vital in showery regions like Hawaii , while full sun—6 - 8 hours day by day — ride yield production . confidential information protection ( for example , instinctive hills or tree lines ) shields its upright tree and medium - stocky - skinned fruit from price . Sites near coffee or macadamia tree plantations , vulgar in Kona , allow complemental microclimates .

Tree Propagation

Sharwil is propagated by graft onto fearless rootstocks like ‘ Zutano ’ or ‘ Duke 7 ’ to insure disease electrical resistance and consistent yield traits . seed wo n’t bring forth true Sharwil yield due to its hybrid nature , so nursery bribery — scion from licence trees — are grow for 12 - 18 months before transplanting . This preserves its humble seed and rich flesh .

Sir Herbert Beerbohm Tree are space 15 - 20 human foot ( 4.5 - 6 meters ) apart to allow for canopy spread , though tighter spacing ( 12 - 15 infantry ) works with pruning in high - density setups . Late outflow planting , after freeze risk of infection , is idealistic in California or Hawaii , giving roots time to establish before summer rain or high temperature . Holes twice the root ball ’s size are enriched with compost , often mound in wet climates .

Irrigation

Sharwil needs consistent but moderate watering—20 - 40 gallons ( 75 - 150 liter ) per Sir Herbert Beerbohm Tree weekly , adjust for rainfall , specially in Hawaii ’s soaked season . drip mould irrigation target the root zone , keep off supererogatory wet that invites rot . Young tree diagram demand 2 - 3 hebdomadary seance , sharpen as they ripen . wet monitoring prevents overwatering in humid conditions .

Fertilization

Nitrogen is applied at 1 - 1.5 Irish pound ( 0.45 - 0.7 kg ) per tree yearly , split into three VD ( leaping , summertime , fall ) to match its long fruiting cycle . Phosphorus and K bolster yield character , often added via balanced fertilizers ( e.g. , 10 - 5 - 10 NPK ) . micronutrient like atomic number 30 and atomic number 12 , lacking in volcanic soils , are supplemented via foliar sprays , maneuver by folio depth psychology .

Pollination

Sharwil is a Type B flowerer — female in the afternoon , male person the next sunrise — partially ego - fertile but yielding well with hybrid - pollenation . Pairing with Type A change like ‘ Hass ’ or ‘ Pinkerton ’ heighten fruit set , as bee bridge bloom overlaps ( October - January in Hawaii , January - April in California ) . beehive are often introduced to hike up pollination in commercial-grade orchards .

Pruning

Light pruning anatomy Sharwil ’s unsloped trees , removing idle Sir Henry Wood or herd arm to improve airflow and light in humid climates . untried Tree are take into an receptive form over 2 - 3 old age , while matured tree diagram get annual cutting Charles William Post - harvest ( springtime ) to manage yield loading . laboured cuts are avoided , as its natural vigor supports its medium - sized fruit .

Pest and Disease Management

Avocado thrips and mites are key plague , ensure with predatory insects ( e.g. , lacewing fly ) or horticultural vegetable oil . Root bunk and fruit fly risk of infection ( notably in Hawaii ) are mitigated with resistant rootstalk , strict sanitation , and USDA - compliant heat treatment for export . even reconnoitring and debris remotion curb issues , particularly in sloshed time of year .

Fruit Development

After pollination , Sharwil yield matures over 10 - 12 calendar month , quick for harvest from November to February in Hawaii or February to May in California . It ripen off - tree , with dry thing content ( 20 % lower limit ) bespeak maturity . Fruit weighs 8 - 16 ounces ( 225 - 450 gm ) , with size of it tied to water , nutrients , and thinning to prevent arm strain .

harvest home

Sharwil is break up mature but firm , with clipper ship cutting stem to avoid rupture its medium - thick-skulled cutis . Timing aligns with oil capacity tests , peaking in wintertime for Hawaii ’s export market or spring in California . Workers use ladder or magnetic pole , roll up into padded bins to protect its yield , which offend less than thin - skinned types but requires attention .

Post - Harvest Care

Harvested fruit is cool down to 45 - 50 ° F ( 7 - 10 ° century ) to slow ripen , then rank for size and blemishes . In Hawaii , export fruit undergoes hot water handling ( for instance , 114 ° F/46 ° C for 20 minutes ) to meet USDA fruit fly protocols . ripen fall out off - tree at 65 - 75 ° F ( 18 - 24 ° C ) over 7 - 14 day , or faster with ethylene . fledged tree yield 100 - 200 pounds ( 45 - 90 kg ) annually with proper management .
