One watering bag can hold about 75 l of water. When watering trees, this amount of water is poured in at least two parts into the watering wells installed at the roots of a tree by staff who come with a water tank vehicle. This takes at least 10-15 minutes per tree. The watering bags therefore save both staff time and the cost of travelling to the site. One bag is filled with water in one minute on average.

The water drips out of the bags slowly and provides even and constant irrigation to the roots of the plant. One such bag empties in 8-10 hours.

In some places, the water is supplemented weekly with a biohumus concentrate to give the trees not only water but also nutrients.

In Vilnius, on the banks of the river Neris and in parks, city residents notice fallen and decaying trees. This is not negligence on the part of the city’s caretakers. Dying, rotting trees enter another life cycle — they become homes and food for other smaller animals, insects, plants, fungi, and later turn into fertiliser for the soil.

These trees are particularly important for the ecological health of a natural area. A single fallen tree contains more than 5,000 organisms of all kinds that feed on dead wood. Both dead trees that are still standing and those that have already fallen and are decaying are valuable. They are home and food to a variety of life forms.

This is the first 1000 sq. m green roof in Vilnius. Nine types of stonecrops have been chosen to liven up the roof, with more than three thousand different plants added to the stonecrop cover. This also contributes to increasing biodiversity. Perennial, heat-loving flowering plants that thrive in the sun, such as thyme, oregano, calamintha, strawberries, and spurges, were planted. Carnations add colour, and some white mugwort has been planted. There is a watering system for the plants. The roof terrace of the Lazdinai pool is open to the public. A rooftop café is planned in the near future.

Urban gardens, with vegetables and herbs among the flowers, are becoming increasingly popular in European cities. Such an unusual flower garden has been planted in Šnipiškės, near the CUP shopping centre. Herbs and flowers such as marigolds, nasturtiums, anise hyssops, apple mint and cosmos grow there.

In addition, there are over 400 pumpkins, almost as many chards, curly kales, corn, scarlet runner beans, fennels, and almost a hundred field tomatoes.
