Terracotta pots are always the best of the pots. The clay pots breathe. The small pores on the terracotta surface allows the water to dissipate outside and help the roots breathe better. The best of roots help develop an healthy and vigorous plant. Terracotta pots are very near to the nature. The color, material and the texture makes you feel the earth. You can always discard the terracotta pots guilt free.
