Generally speaking , program of a mulch in a garden provides many benefit . Citrus tree diagram grow best when their soil is prolific and systematically moist and when sess competition is low – all condition that are meliorate with the employment of mulch . Do n’t be overzealous with the use of mulch around citrus as too much mulch or the ill-timed kind of mulch can produce less - than - worthy termination . When in doubt , consult a local plant life glasshouse or your concerted extension office for advice based on your climate , soil , and insect and disease threats in your orbit .

Mulch Away From Trunk

source and soil fungus is a primal concern for all types of citrus trees in the home landscape . The endangerment for fungal problem increases as soil moisture increment . Depending on your region ’s territory and the specific irrigation agenda in your garden , keep mulch well away from the trunk of your citrus tree . This is a fine balance between the benefit of mulch retarding weeds and retaining soil moisture for the roots while also allowing the stain and tree trunk to dry out readily and not harbor fungus . Keep mulch at least 1 foot away from the citrus fruit tree diagram ’s tree trunk , and if soil are always irrigated , keep the grime immediately under the tree ’s canopy free from mulch . If you do cultivate under the tree with a hoe , do so lightly so you do not damage the citrus tree diagram ’s surface roots .

Mulch Depth

Within the citrus tree diagram plantation , scatter mulch to a depth of 2 to 4 inches . This depth is recondite enough to shade the land , retard locoweed sprouting and reduce soil moisture vaporization but not so deep as to reduce oxygen levels in the topsoil or keep grunge moisture levels too wet and encourage fungous result .

Use Organic Mulch

constituent mulch , those that are derived from deadened works materials , may be better overall than using plastic , India rubber or careen , depend on your local soil and mood . Overall , the constitutive mulch degrades to improve the nutrition and texture of filth as well as promote good microorganisms in the soil . Inorganic mulches typically do not and can retain heat from the sunlight , increase soil and airfoil temperature , which may top to the citrus fruit tree ’s requirement for irrigation .

Use an Acidic-Forming Mulch

Unless your native dirt is already quite acidulent ( pH below 7.0 ) , using an constituent mulch that decay and lowers pH can decrease nutrient lack that make chlorosis , or yellow of leaves . Soils that are acidic tend to allow freer stem absorption of iron , magnesium and manganese . In impersonal to alkaline soils these micro - nutrients are not pronto absorbed and sickly yellow - green to pale yellow foliage develops . Acid - forming constituent mulches include pine bark , pine bark fines , pine husk , coffee grounds and oak tree leaf mold .

Pull Back Mulch for Frost

If wintertime jeopardise a nighttime Robert Frost , draw back mulch the sunup before the expected frost allow the sun to heat the soil well under and around the Sir Herbert Beerbohm Tree . Then at Nox as air temperature drop , radiant heat from the soil is captured by the citrus tree ’s leaves and branches , potentially protecting it from coarse cold damage .
