Why does my clay pot crack?

What happens? Usually, the water enters and drains out of the pot without any issue. But during the winter months, the water can become trapped inside of the planter and freeze, which means it also expands. This expansion causes the pot to crack.

Do clay pots crack in the winter?

Clay pots may look sturdy and strong, but they’re often fragile and easy to chip or break. Because they’re porous, they absorb moisture like a sponge. Changes in the temperature, or freezing rain and snow can cause them to crack as the clay expands and contracts.

What do you put at the bottom of a plant pot?

Light Materials If you have an especially big planter to fill, light, bulky materials are your best bet. Examples include plastic drink containers, milk jugs, crushed soda cans, foam packing materials and plastic or foam take-out containers.

Should you put rocks at the bottom of a planter?

In general, it’s not necessary to put rocks in the bottom of plant pots. One rock to cover the drainage hole is enough – just enough so that the soil doesn’t leach out of the bottom but water can flow freely through the pot. Putting rocks in plant pots doesn’t aid drainage or improve air circulation.

Can you leave soil in pots over winter?

Storing Terracotta or Clay Containers for Winter Terracotta or clay pots cannot be stored outdoors. Since they are porous and retain some moisture, they are prone to cracking because the moisture in them will freeze and expand several times over the course of the winter.

What do you put in the bottom of a flower pot for drainage?

A drainage layer is created by adding a medium such as pebbles, stones or pumace to the bottom of a pot before adding soil. Soil particles are very small and tightly packed together, which means that water moves through them quite slowly.

Should all flower pots have holes?

Our answer is yes, but with caution. What is the purpose of a drainage hole? All plants need water to survive. Drainage holes allow excess water to seep out of pots after watering, ensuring that water does not pool at the base of a pot, helping to protect sensitive roots from rot, fungus and bacteria.
