Vine-growing has a long tradition in Lysolaje. There used to be many vineyards here, but they disappeared during the lengthy Thirty Years' War. The reclamation of the Denkra sand pit, mined out long ago and then covered by an illegal black dump for years, has recently seen the reinforcement of the original mining walls, with new greenery planted, paths and sports grounds built, and in the spring of 2019, a vineyard was established during landscaping work to stabilise the slopes formed during the mining process. A total of 540 vine heads were planted here, two white varieties and one red, all from Mělník. The entire planting process and aftercare were also consulted with the Mělník winegrowers. The vineyard is situated on an east-facing slope, yet the layout of the surrounding land means it receives sunlight throughout the day. The vineyard is part of a newly opened multi-purpose sports and leisure complex.
