With improved living conditions these days, people tend to grow a few potted plants at home, but they are often not taken care of properly, and die after a short time. It can be said that the vast majority died from drowning, caused by excessive watering – frequent irrigation leading to root rot and lack of oxygen. Expanded polystyrene (already foamed) has the properties of insulation, water resistance, light weight, and non-adhesion to soil. Given the properties of EPS, adding a portion of foam particles (1/5–1/4) to the planting medium, along with using small foam blocks at the bottom of the pot, can help reduce weight. It also allows water to drain quickly after each watering, thereby lowering the overall moisture level in the soil. Since foam particles do not absorb water, they help to loosen the soil and improve ventilation (similar to the function of perlite). In winter, they also provide insulation. If used in combination with polyvinyl alcohol (a soil conditioner) and ferrous sulfate (a soil pH regulator), it will certainly help to nurture flowers well.
Many applications for flower pots. Adding a portion of foam particles (1/5–1/4) to the planting medium, along with using small foam blocks at the bottom of the pot, can help reduce weight. It also allows water to drain quickly after each watering, thereby lowering the overall moisture level in the soil. Since foam particles do not absorb water, they help loosen the soil and improve ventilation (similar to the function of perlite). In winter, they can also provide insulation. This little tip is worth using.

I really should give it a try; Duo doesn’t have many flowers each year.
When I grow flowers, especially orchids, I use foam – namely foam boards and the like – which is crushed and mixed with soil, vermiculite, pine bark, peanut shells, and pine needles. Adjust the pH level twice a year using ferrous sulfate, and apply potassium dihydrogen phosphate solution as a spray multiple times.

Hello, I would like to ask about the degradation rate of this type of EPS – could it harm the soil structure? ?
EPS has poor degradability and causes white pollution.
