For example, only native species of plants are permitted and they must only be planted in peat-free compost.
But it is of course worth jumping through hoops to make an appearance at Britain's most prestigious flower show, thanks not least to an annual visit from Her Majesty Queen Elizabeth II. And the 2019 show received tremendous press attention thanks to the RHS Back to Nature Garden, which was co-designed by Her Royal Highness The Duchess of Cambridge.
Months of preparation went into weathering the stones and slabs before we cleaned 50% of them to demonstrate the effect of The Patio Black Spot Removal Company's biodegradable and pet-friendly black lichen remover.
The show was a whirlwind, with only five days to build the stand ready for the gala opening day. And five days later we were given just one day to dismantle it and take it away. But our 4 star award made all the team's hard work worthwhile and the client was thrilled with the return on investment after one of the most successful shows the company has ever had.
