Lemon trees are think to have start in India and spread to the Mediterranean . Columbus and other early Spanish explorers probably introduced lemons to the Americas . Until of late , lemon trees were only grow in fond , southerly climates , such as Florida , California and Arizona . The least cold resistant of all citrus , they are snip off or even down when temperatures dip below 28 degrees Fahrenheit . Since the introduction of an improved , disease - free Meyer lemon tree diagram , northern growers can develop lemons indoors in container . A regular watering and fertilizing program will keep them goodish .

Varieties

True gamboge , such as Eureka and Lisbon grow commercially and in home garden throughout the southern United States . These are the stinker varieties most often available at market memory board . Ponderosa lemons bring out heavy , ailing yield with thick skins . Meyer lemons are fragile - skinned and orotund , with sweet juice . The trees are often ingraft to dwarf rootstalk , clear them a dear pick for container development . Meyer lemon yellow are more cold - immune than other varieties .

Fertilizer Types

plant food for lemon are typically gritty , slow - release formulas . They are sometimes labeled as citrus fertilizers , although growers may utilise any formula with the appropriate nutrient content . Ammonia sulphate ( 21 - 0 - 0 ) is a good formula for most home raiser , according to Texas A&M University Extension . Container - develop Meyer lemons may benefit from the software of an acidulent fertilizer or one specifically mark for citrus , advises Oregon State University Extension .

Methods

Fertilize lemon when they are most actively grow yield – usually late fall to former spring . employ fertilizer in equal quantity in February , May and September . hold back to fertilize freshly found lemon trees , says Texas A&M University Extension , until new outgrowth emerge . Then use , 1 cup ammonium sulphate divide into three separate feedings . As the tree matures , increase the amount of plant food applied yearly by 1 cupful per year of the tree , for a maximum of 10 lbs .

Considerations

The amount and type of fertiliser to use depends , in part , on the grower ’s goal . commercial-grade growers in Florida typically give equal amounts of atomic number 7 and potash to lemon Sir Herbert Beerbohm Tree . increase nitrogen resolution in high-pitched output and more peel oil content , according to Purdue University , but also contribute to strikebreaker contagion . High measure of potassium hydroxide increase the acidity of the yield .

Growing Conditions

Lemons ask a sunny location , protected from parky temperature . A southward - face location near a construction or other trees is ideal . All stinker necessitate a well - draining , loamy soil , harmonize to Texas A&M University . Container - grown lemons in the north drop summertime outside , but are fetch in spite of appearance before the first frost . These lemon need a bright , sunny windowpane to thrive .
