Cișmigiu continued to be developed by Meyer long after its official inauguration: in 1870, the horticulturist laid out a plan to redesign the lanes, to introduce an artesian aquifer, and to create a kiosk for an orchestra. He also proposed to have gondolas carrying visitors over the lake. By 1851, new species of trees were brought in: chestnuts from Gorj County, walnuts from Dâmboviţa County, and other plants from places such as Vienna and Brașov. At the same time, the lanes were reinforced with debris from the ruins of Curtea Nouă and Zlătari area. Works were completed despite Meyer's sudden death as a result of typhoid fever in August 1852.
