Fertilize: For optimal growth of big trefoil, use balanced fertilizers, adjusting feeding seasonally: increase in spring, reduce in autumn. Fertilize monthly per package instructions to enhance growth and flowering. Avoid over-fertilization to prevent nutrient burn, applying to moist soil and adjusting as big trefoil matures.
