Plants that grow in plastic pots for a long time will grow poorly or even die because of limited root respiration; In addition, plastics will crack in the sun, and plastics will age, releasing toxic substances, endangering plants and human health, which is not good for the environment.

stean

This flowerpot has good air permeability and strong water permeability, which is beneficial to plant growth. However, because this material is not suitable for modeling, the appearance of pottery pots is generally not very good, and the ornamental value is also average. Moreover, the pot made of this material is easy to get dirt and dust, and it is not easy to clean. Therefore, pottery pots are rarely seen in the market, and occasionally they can be seen in traditional families.

Porcelain basin

The porcelain basin itself is very ornamental, but its air permeability is not very good. Because the glaze on the outside of the porcelain basin blocks the way in and out of the air, the bottom of the porcelain basin is made of a simple drainage layer made of materials with good air permeability, such as pebbles or preferably large ceramsite (hydroponic materials, available at the flower market). A special drainage layer is also needed around the flowerpot wall. The method is as follows: firstly, thick paper (such as kraft paper) is rolled into a small cylinder smaller than the diameter of the flowerpot, and coarse river sand is filled in the gap between the cylinder and the inner wall of the flowerpot. After the cylinder is filled with the soil needed for planting, the circular paper tube is pulled out, which can ensure the good air permeability at the bottom and around the cultivated soil.

Pottery basin

Pot is a flowerpot with beautiful appearance and good air permeability. But the pottery basin needs to be raised with water, otherwise it will gradually dim. In addition, clay pots are very picky about water quality. If the water quality is alkaline for a long time, white stripes will appear on the surface of the pottery jar, and neutralization reaction will occur, and acid and alkali will combine to form salt, so the flowerpot will not look good, and there are fewer plants using the pottery jar, and the pottery jar is a bit heavy.

Straw flowerpot

Straw flowerpots have the advantages of thin wall and environmental protection, which is not bad. It is made of straw, so it breathes well. However, due to the production process, there are few styles of straw flowerpots, and the gap of straw compressed products is relatively large, which is easy to seep when watering, and even water droplets will seep under the tray, which affects the external cleanliness.

To sum up, it is recommended to use clay pots and straw flowerpots on the balcony.
