Quizplus · Accepted Answer

A pH above 10.0 is extremely alkaline and most plants prefer a pH range between 5.5 and 7.5. A pH above 10.0 would inhibit the growth of most plants due to the high concentration of hydroxide ions, which can disrupt nutrient uptake and cause toxicity. Abundant humus, air spaces, and good drainage are beneficial for plant growth.
