Plastic can become brittle and crack over time, especially if pots are exposed to cold temperatures (more of a problem if they are outside, especially if you leave them outdoors to overwinter). They can also become brittle if they have a significant amount of UV exposure.
Similarly one may ask, do plants grow better in plastic or ceramic pots?
Air movement stimulates root growth, which results in healthier plants. But the clay also wicks moisture out of the soil, making ceramic pots a better choice if you tend to overwater or for plants that prefer dry soils. This also means plants in ceramic pots require more water than plants in plastic pots.
Then, which plants like plastic pots?
Plastic remains wet.
This can mean more watering in certain plant species but is useful to prevent root rot and soil fungus. This action helps prevent certain insect pests that like moisture too. They’re perfect for cacti and succulents because the soil will dry quicker and the walls are thick and protective.
Are glazed pots good for plants?
Plastic and glazed ceramic pots are excellent for tropical plants, which typically like their soil to stay moist. These pots hold in moisture, which allows you to go longer in between waterings.
