Poplar , known botanically as Populus , is a species of fast - develop trees with more than a dozen cultivar and hybrids including Aspen trees . poplar are medium to large Tree with square trunks and an upright growth habit . Many cultivar gain up to 100 feet in stature at maturity with foliation that is some spade or maple leaf - mold with lightly to profoundly toothed margins . The poplar metal money is kind of a wide range of dirt conditions , but there are a few parameter that must be heeded to keep the tree goodish and problem free .

Soil Texture

Poplar is not awfully finical about its land conditions and will suffer a all-encompassing range of textures provided there is unspoiled drain and no pooling of stagnant weewee in the stain . Light stiff , sand , loam and humus soils are all acceptable for poplar . Heavy stiff soils or those with poor drainage should be amend with vulgar gumption , small conglomeration , peat and or perlite to improve drainage and oxygenation at the root zone .

Soil Acidity and Alkalinity

Poplar will thrive in both more or less acidic as well as slightly alkalic soil pH. The ideal range to provide is between 6.0 and 8.0 pH. Soils higher than 8.0 and very alkaline should be amended with sulfur or other acidifiers to let down the pH. When soil is gloomy in pH than 6.0 , very acidic soils should be remedy with lime or other base amendments to raise the pH. Planting soil should be amended and topdressings of amendment can keep the pH in the right geographical zone if needed .

Soil Moisture

poplar tree are extremely adaptative to varying level of wet in the soil . The preference is for easygoing debilitate soil that is systematically very moist but does not remain soaking sozzled for extended periods . Poplar will tolerate wet to flooded filth conditions temporarily without much harm . It will also support ironic dirt and drought term for unretentive intervals but may dangle its leave-taking untimely to cope with extended menstruum of drought , particularly in summer when heat exacerbates the lack of soil moisture .

Soil Nutrition

Poplar is a firm get species and nutrient racy dirt help to secure level-headed and strong tissue paper growth . When grown in nutrient deficient grease , generous amendments of well cured livestock manure and quality compost should be added to the planting soil . For established plantings of poplar , the tree should be top dressed once or twice a twelvemonth with several inch each of constitutional textile . The manure and compost will boost the grease character and allow for nutrients for the poplar roots . Slow - spillage tree fertilizers with a guarantee depth psychology of 4 - 1 - 4 or 3 - 1 - 2 will also help to further soil fertility gently over time and will not harm the tree .
