It is estimated the Duke and Duchess of Sussex spend up to £15,000 a month on gardening but the latest “stop watering” notice threatens to push up the cost of tending to their estate.
The couple is said to be incredibly fond of their garden which features pruned rose gardens, elaborate topiary, fruit trees, tall Italian cypresses, blooming lavender bushes and century-old olive trees.
But they have been instructed to preserve water alongside other residents in Montecito fears that the recent dry weather will cause forest fires, the Telegraph reports.
The new rules imposed after 80 per cent of California fall under “extreme” or “exceptional” drought conditions in mid-December will last a year and there are no exceptions for golf courses or other recreational facilities.
The royal couple will also be subjected to the rules as their nine-bedroom, 16-bathroom property is particularly prone to drought because historic topography maps and photos show it was built on land with no natural creeks.
The estate also features is a swimming pool, an artificial pond, a babbling brook and a small waterfall.

The property also features a small well, which has caused some controversy in the past as one local water expert, who remained anonymous, told the Telegraph: “There is only a certain amount of available water for the community, no one really knows how much.
“Why should the wealthy be able to drain these community water sources at will, from their private wells without oversight, only to sustain lush green lawns and gardens?”
