Point taken, but I was thinking of money. Perhaps simply saying that you thought the gardens were beautifully maintained and here's 20,000 rph to say thank you.
I do know that at some specialist hotels in New Zealand where the gardens are a feature of the hotel that it would not be unheard of for a tourist to have a chat with the gardener about their work and slip them a fiver to buy a drink.
