Mourners are being urged not to leave teddy bears, balloons or lit candles among the floral tributes to Queen Elizabeth II.
The Royal Parks said no gifts or artefacts will be accepted and that non-floral objects should not be taken.
Thousands of well-wishers have laid flowers close to Buckingham Palace, Windsor Castle and Balmoral since the monarch’s death was announced on Thursday.
Writing on its website, The Royal Parks said people are invited to leave floral tributes at a dedicated site in Green Park close to Queen Elizabeth II's London residence.

Mourners are asked to remove any wrapping from flowers before they are laid.
The floral shrines at royal residences over the last few days have included tributes such as teddy bears, Corgi soft toys, balloons and marmalade sandwiches in a nod to Queen Elizabeth II's Platinum Jubilee sketch with Paddington Bear.
The Royal Parks said cards and labels will be accepted, adding: “Unfortunately, no gifts and artefacts will be accepted and the public will be asked not to bring these to the parks.
“Non-floral objects/artefacts such as teddy bears or balloons should not be brought.”
They added that it will not be possible to light candles in the parks and that lit candles will be extinguished.
Tributes will be left on site until all ceremonial activity has taken place and it is expected that flowers will be removed from park areas from seven to 14 days after the date of the funeral.
Flowers that have deteriorated will be removed throughout and taken to the Hyde Park nursery for processing to prepare them for composting.
