19. z 2. Increases nutrient absorption

20. z 1. Aerobic aspiration will give roots energy to grow 2. Increases nutrient absorption 3. Lack of air allows pathogens to quickly kill the plants

21. z “Circling roots (in potted) plants have difficulty getting enough water and nutrients, shortening plant’s life span.” -Oregon State University

22. z z “Circling roots are ‘burned’ off or pruned when exposed to air, causing the plant to constantly produce new and highly branched roots.” -Washington State University

24. z z Air alone has many benefits for plants growing in a container

25. Nutrients are washed down & out A container with good drainage
