The municipalities, which often realize a garden show with the help of state funds, take a calculated financial risk.
While some state garden shows closed with a "black 0" or even with slight profits, others exceeded their budget and had to be subsidised retrospectively.
Since 2001, they have been held annually, alternating with the "small state garden shows", the so-called green projects.
For this reason, the state government decided as early as 1996 to carry out the smaller "green projects" in Baden-Württemberg every two years from 2001 onwards.

A show was to take place in the landscape park Brodaer Höhe of Neubrandenburg, but it did not go beyond the design phase.
This was initially suspended because the applicants Güstrow and Putbus were unable to present a financially sustainable concept.
[15] After the state government failed to provide the financial means, the BUGA 2025 was returned to the German National Garden Show Society mbH (DBG) 2017.
On July 26, 2018, Rostock launched a BUGA application and was officially awarded the contract to host the National Garden Show 2025 on September 10, 2018.
