We got a really good deal on an olive tree at Morrisons. The average price for a ‘cheap’ online planter that’s around 50x50x50cm in size is £50 and they are made from thin, flimsy wood, and we needed two. We did the maths and good quality, treated wood for two 60x60x60cm box planters was going to cost us around £40, a saving of £60.
