The origin of the lemon , or Citrus limon , Sir Herbert Beerbohm Tree is unknown . In 1493 Christopher Columbus is said to have land gamboge seeds to Hispaniola . It is quite possible that the Spaniards introduced the lemon to St. Augustine , Florida . According to the University of Florida , " Citrus tree growth and productiveness is closely linked with root organisation health and both can be seriously affected by unlike territory borne pests and diseases . " So , the root system of the lemon yellow tree is very important .

Characteristics of the Root System

The root scheme is made up of woody lateral root , which radiate out from the trunk of the Sir Herbert Beerbohm Tree . Fibrous root grow from this connection of lateral root word . Not only do the root anchor / hold the tree , they transport the required water system and nutrient so that the tree can grow and farm fruit . The fibrous ascendant are the main site of H2O / nutrient transport . Most tree have a taproot , but this may not be present in a mature gamboge tree .

Root Growth

The surround flirt a key purpose in lemon tree diagram root increase . Both soil temperature and wet are very crucial . During the months of February through former December , root growing of the lemon Sir Herbert Beerbohm Tree is periodical ( roots do not spring up during shoot flush ) . In bounce , summertime and fall , origin outgrowth replacement with shoot ontogenesis . The University of Florida states , " This alternation of growth is thought to occur as a result of rival between roots and shoots for photosynthetic sugar . "

Root Loss

The young root growth increase the rootage system of the lemon tree . In some instances , the new tooth root supervene upon dead ones . Fibrous root are moult throughout the year as well . Fibrous tooth root can die because of oversupply soil or poor aeration .

Soil Pests

The same soil temperatures that are conducive to root growth are also contributing to nematode and fungous development ( citrus roundworm and phytopthora ) . This loosely occurs in April through May and October through November . Nematodes do not drink down a lemon tree but they will abbreviate the growth of the Sir Herbert Beerbohm Tree , bear on the numeral of lemon produced and shorten the tree ’s dynamism . As the nematodes damage the roots , you will acknowledge a thinner canopy on the tree and sprig dieback . dirt and root samples should be contain to determine if you have a problem with nematodes . you could not get rid of roundworm . One solution to this problem is to constitute rootstalk that is resistant , such as Milam lemon tree .

Citrus Phytopthora Root Rot

Disease symptom are similar to an infestation of citrus nematodes . This disease will ruin the feeder roots . Once the feeder roots are destroy , the tree is unable to take in piss and nutrients and the tree diagram will finally die . It is salutary to establish rootstalk that is resistant to citrus phytopthora root decomposition . fit in to the University of California Statewide Integrated Pest Management Program , " direction of phytophthora ascendent rot call for the use of tolerant rootstocks , irrigation management , fungicides and fumigation .
