The response of trees to weed control treatments and tree shelters are consistent with other studies, which suggest a positive effect related to the interplay of microclimate change and resource availability.
Hay fever, which is caused by an allergy to grass, tree or weed pollens, is believed to affect about 10% of the population.
Understanding the impact of a variety of known and biologically plausible environmental irritants and triggers among children in New Jersey – ozone, fine particulate matter (PM2.5), tree pollen, weed pollen, grass pollen and ragweed – would allow for informed public health interventions.
Significant associations found in 5 12 yrs age group for tree and weed pollen concentrations also suggest that this age group may be at greater risk for outdoor exposures triggering reactive airway conditions due to greater time spent outdoors.
For bumper crops, apply a general fertiliser in spring, keep the tree base weed-free and thickly mulched, and water regularly in dry periods.
In early years after planting, the area around each tree was weeded by hand to remove competing vegetation.
