Most of the cycads were growing in hard-to-reach places, so we had to have the correct instruments, a lot of determination, and a little bit of luck. By The important thing about cycad roots is that, when the plant is doing poorly, the problem is often in the roots. As a result, the numbers and types of bacteria inside the coralloid root are different than in the bulk soil and rhizosphere, as seen in Figure 3. In containerised plants, CAS usually aggregates on primary roots (about 10mm in diameter), and singly or in groups of a few on secondary roots (about 2mm in diameter) near . We also collected the rhizosphere and other soil from the area around the cycads. It might be best if you avoid planting shrubs and trees near the septic tank area.
