Fuerte avocados belong to to the species Persea americana within the Lauraceae family , a botanical grouping that include redolent plants like cinnamon and bay laurel . Classified as a berry due to its single - sown , sarcoid fruit , Fuerte is a hybrid cultivar with a mix of Mexican and Guatemalan origin . The Mexican filiation ( about 60 - 70 % ) lends it insensate tolerance and a thinner skin , while the Guatemalan influence ( 30 - 40 % ) contributes to its magnanimous sizing and rich flavor . This hybrid vigor helped it become a commercial-grade standout in the early 20th C before Hass eclipsed it .
The origin of the Fuerte avocado trace back to Puebla , Mexico , where it was discovered around 1911 by plantsman Carl Schmidt . Working for the West India Gardens nursery in Altadena , California , Schmidt accumulate cutting from an exceptional tree owned by a farmer nominate Alejandro Le Blanc . name “ Fuerte ” ( Spanish for “ strong ” ) for surviving a harsh 1913 freeze that kill many other varieties , it was introduced to California growers and apace rose to swelling . By the 1920s , it was the leading U.S. avocado tree , jimmy for its quality and resiliency , until Hass overhaul it in the 1970s .
Identifying a Fuerte avocado is easy once you know its traits . It ’s pear - shaped with smooth , slender , bright green pelt that remains green even when ripe — a contrast to Hass ’s darken peel . The yield typically count 8 to 14 apothecaries' ounce ( 225 - 400 grams ) , with wan green flesh that ’s creamy but less soapy than Hass ( oil depicted object around 12 - 16 % ) . Its texture is smooth and slightly hempen , with a large , teardrop - shaped seed that have up obtrusive space . The skin peels away easily , reveal a subtle luster on the build .
Fuerte avocados produce best in USDA Hardiness Zones 9 to 11 , thriving in mild , semitropic clime with minimal Robert Frost risk . They tolerate temperatures down to about 26 ° F ( -3 ° C ) well than pure Guatemalan varieties , thanks to their Mexican genes , but prolonged cold damages blossoms and young yield . California ’s coastal region , like Ventura and Santa Barbara Counties , are prime develop area , as are part of Florida and Mexico . Well - drained , loamy soils and full sun exposure are non - negotiable for healthy tree , which can pass 30 - 40 feet if unpruned .
Seasonality for Fuerte running game from late autumn to early fountain , typically November to April in California , form it a winter standout when Hass production dips . Unlike Hass , which can hang on trees for months , Fuerte ’s thinner peel demarcation line on - Sir Herbert Beerbohm Tree storage , so it ’s harvested matured but unfaltering and ripen off - tree diagram . handiness has waned as Hass dominates year - round supply via imports , but Fuerte rest a niche pet in local securities industry or specialty stock , especially in region where it ’s still grown . Its peak quality aligns with cooler months , offering a seasonal contrast .
Culinary enjoyment of Fuerte avocado pear skimpy on its milder , grassier flavor and less dense texture . It ’s less ideal for heavy guacamole — its humiliated petroleum content can make it watery when coquette — but shines in saucy applications . Sliced into salad with citrus fruit or tomatoes , it adds a delicate creaminess without overmaster other ingredients . Spread on goner or blend in into dressings , its subtle taste couplet well with herbs or spices . In Florida , where high - water - content avocados are common , it ’s often scooped flat from the hide with a mizzle of calcined lime . Its lighter visibility hit it a refreshing alternative to rich varieties like Hass .
Cultivation of Fuerte Avocados
mood requirement
Fuerte avocados prosper in semitropic climate within USDA Hardiness Zones 9 to 11 , prefer mild temperature between 60 ° F and 80 ° F ( 15 ° century to 27 ° cytosine ) . Their Mexican ancestry give them comfortably dusty permissiveness than virtuous Guatemalan diversity , surviving abbreviated drops to 26 ° F ( -3 ° C ) , though frost damages blossoms and young fruit . agriculturalist in coastal California or similar freeze - free zone often apply wind machines or sprinklers during rare cold snaps to protect crops .
Soil Preferences
Well - drained soil is critical , as Fuerte is susceptible to stem rotting ( Phytophthora cinnamomi ) . Sandy loam or loam soils with a pH of 6.0 to 6.5 are ideal , allowing water to leach quickly . Heavy Lucius Clay want amendment with constituent thing or raised beds to prevent waterlogging . Soil testing before planting secure proper drainage and nutrient horizontal surface , as Fuerte ’s shallow roots demand aeration .
situation Selection
lightly sloping sites ( 5 - 10 % grade ) are preferred to shed spare water , though flat land works with heedful irrigation . Full sun—6 - 8 hours daily — is non - negotiable for yield solidification and ontogeny . malarkey protection is fundamental , as Fuerte ’s thin - skinned fruit and blossoms are vulnerable to harm ; natural barriers like J. J. Hill or planted windbreaks ( e.g. , eucalyptus tree ) shield orchards effectively .
Tree Propagation
Fuerte is propagated via graft onto brave rootstock like ‘ Topa Topa ’ or ‘ Mexicola ’ to ensure disease resistance and consistent fruit trait . seeded player from Fuerte yield wo n’t breed true due to its hybrid nature , so baby’s room - grown transplant ( scions from certified trees ) are standard . Young trees are sustain for 12 - 18 month before transplant , establishing a strong root system .
Planting
tree are space 15 - 20 metrical foot ( 4.5 - 6 metre ) apart to accommodate their broad canopies , though denser planting ( 12 - 15 feet ) is potential with pruning . bounce planting , after the last icing , is optimal in neighborhood like California , giving roots clock time to settle before summer heat . Holes twice the root clump ’s size are filled with compost - amended soil , and bet underpin trees against wind for the first year .
Irrigation
Fuerte require uniform but restrained watering—20 - 40 gallon ( 75 - 150 liters ) per tree each week , depend on geezerhood and rainfall . dribble irrigation aim the theme zone , quash trunk impregnation that invites rot . Young trees postulate watering 2 - 3 time weekly , while mature single adapt to less frequent cycles . Soil moisture is monitor to prevent overwatering , a common pitfall with this miscellanea .
Fertilization
Nitrogen drives Fuerte ’s growing , applied at 1 - 1.5 pounds ( 0.45 - 0.7 kilo ) per Sir Herbert Beerbohm Tree yearly , split between early spring and former summer . Zinc and B addendum correct deficiency usual in alkaline soils , often delivered via foliar sprays . Compost or balanced fertilizers ( for example , 8 - 3 - 9 NPK ) support vigor , but over - fertilise endangerment leaf burn or reduced fruit quality , so annual leaf analytic thinking guides adjustments .
Pollination
Fuerte is a Type B flowerer — female in the good afternoon , male the next morning — making it part self - fertile but more productive with cross - pollination . Planting Type A varieties like Hass or ‘ Pinkerton ’ nearby enhances yield , as bees transfer pollen during overlapping bloom periods ( late winter to springtime in California ) . grower often add hives to orchards to supercharge pollination success .
Pruning
Inner Light pruning work Fuerte tree , remove dead wood , sucker , or crowded branches to improve air circulation and light insight . untested trees are trained into an open , vase - like physique over 2 - 3 old age , while mature trees want only casual thinning post - harvest ( spring ) to avoid accent . dense cut are uncommon , as Fuerte ’s vigorous growth by nature balance yield load .
Pest and Disease Management
Avocado thrips and persea mite are primary pests , managed with predatory insects ( e.g. , ladybeetle ) or point spray like neem oil . Root rot is the liberal disease terror , countered with resistant rootstalk and nonindulgent water control . Regular exploratory survey and sanitation — removing fallen fruit — limit infestations , maintain chemical substance use minimal in sustainable plantation .
Fruit Development
After pollenation , Fuerte fruit matures over 7 - 9 month , reaching harvest readiness from November to April in California . Unlike Hass , it ca n’t hang up long on - tree diagram due to fragile cutis , so time aligns with ironical subject examination ( 18 - 22 % minimum ) . yield grows to 8 - 14 apothecaries' ounce ( 225 - 400 grams ) , with size tempt by weewee , thinning , and tree health .
harvest
Fuerte is pick mature but unripe , when stiff and greenish , using limiter to lop staunch cleanly . Workers aim fruit at flush oil content , test via sample distribution , with harvest sweep late fall to spring . run or Pole progress to mellow branches , and fruit is collected in cushiony bins to prevent bruising its delicate skin — an advantage over tougher - skinned Hass .
Post - Harvest Care
harvest Fuerte aguacate are cooled to 40 - 45 ° F ( 4 - 7 ° C ) to slow up ripening , then grade for size and blemishes . mature occurs off - Sir Herbert Beerbohm Tree at room temperature ( 65 - 75 ° F/18 - 24 ° coulomb ) over 7 - 14 days , or quicker with ethylene in commercial-grade preferences . Thin peel limits shelf life compared to Hass , so timely statistical distribution is cardinal . Trees can produce 80 - 150 pounds ( 36 - 68 kg ) yearly for decades with right forethought .
