Here is one I prepared earlier. Not really...this Bunnings pot is about 5 years old now, but this was my inspiration. I'll let you know how I go.
Why all the effort for some terracotta? I visited the wholesale nursery Plantmark in Melbourne recently, and my delivery of three very cool cacti arrived last Friday - and they all deserve a fancy new home. I love the idea of planting...I can only imagine how good it must feel for the plants, stretching 'their legs' after being cooped up in those tiny plastic pots.
