Magnolia tree solution suffer damage due to a spacious array of causes admit environmental return , job with precaution , infestations and infection . Familiarize yourself with necessary culture and maintenance for vigorous development . By identifying potentially invasive conditions that may touch root health , you will know the type of symptoms to see for with corresponding control method for sizeable roots .
Proper Care
heedful adherence to care requirements ensure good for you growing . Vigorous plants are less likely to experience illness than weakened plants . Grow magnolias in location that provide full sun exposure to partial shade ; find out which magnolia species you are growing for definitive necessary . magnolia thrive in poriferous soil high in nutrient content with an acid pH of 5.0 to 6.5 , harmonize to the Clemson University Extension .
Pests
Pest infestations cause damage tomagnolia tree diagram solution . The magnolia root bore bit ( Euzophera magnolialis ) , for deterrent example , is a pest that feed on magnolia antecedent systems when in the larval microscope stage of development , according to the University of Florida IFAS Extension . The borer more often than not fee on stressed roots . count for poorly formed , shallow ascendant systems as well as trees in declining health .
Disease
Fungal infections like Phytophthora antecedent rot often damagemagnolia tree diagram roots . This contagion acts by fall the size ofmagnolia tooth root , deeming them only partly subject of absorbing necessary water . Most often due to the fungus Phytophthora cinnamomi , this disease attacks magnolia , in particular in too lactating , poorly drained soil . Look for discolored roots in a crimson chromaticity , yellow leaves or shoot , stunted Sir Herbert Beerbohm Tree growth , offshoot dieback or defoliation , according to the Alabama Cooperative Extension System .
Culture
Magnolia Sir Herbert Beerbohm Tree source system grow to a width greater than the canopy of the magnolia tree . ancestor have a habit of girdling or circle the root ball or trunk , according to the Clemson University Extension . Magnolia trees necessitate abundant space for root increase otherwise they will become malformed and damage may subdue optimal role , causing tree decline . Though tree diagram are drouth tolerant as well as tolerant to crocked soil , they will fall poorly quite easily in such cultural conditions if you do not provide ample room for roots , the nutrient immersion center of the magnolia tree .
Solutions
For root scathe prevention and treatment , deal with pests by identifying appropriate pesticide treatments . Insecticidal drenches of the roots and crown of the magnolia tree offer effective assistance in controlling root borer . For root hogwash disease , maintain super well - drained grease as endure water and excessive wet provide the idealistic environment for fungi germination . Apply a antimycotic agent for root buncombe control ; treat Phytophthora root moulder with a fungicide with active ingredients Etridiozole and Thiophanate - methyl , according to the Alabama Cooperative Extension System . For cultural problem , works magnolias in large landscape far away enough from menage and structure for tooth root emergence ; for potted plants , utilize spacious containers . rationalize girdle roots , particularly those forming circles near the filth line , harmonise to the Clemson University Extension .
