Planting of trees in the city centre and along city access roads has been completed. The work took about 45 days. At present , streets have got new birches, oaks, lindens, maples, chestnuts, apple trees, bird cherry, shadberry plus lilac trees, the latter being the only shrub that can be planted during the cold season together with large trees.
“Planting started on 1 November. The work was conducted at night from 11 pm-6 am so as not to cause any inconvenience to drivers. We planted 5,264 trees at over 40 places. Landscaping of Tverskaya Street was completed and after that, a linden alley was shaped there. Trees can be seen on 1st Tverskaya-Yamskaya Street and in a public garden on Tverskaya Zastava Square that has been restored this year. Over 2,300 trees, which makes almost a half of the total number, are decorating the Garden Ring. Thus, the restoration of the ‘green belt’ that existed on the Garden Ring in the 19th century has been completed,” said Deputy Mayor for Housing, Utilities and Amenities Pyotr Biryukov.
City streets have been planted with large-size trees two to nine metres high with crown diametres of one-four metres. These are young but healthy and already strong plants aged between15-40 years grown in specialised nurseries. All the species are adapted for Russian winters and the conditions of a city environment. To form a compact root system, the trees are replanted in nurseries every three-four years. Due to this, they can better endure transportation as well as take better root in a new place.
Specialists say that tree planting in minus temperatures is good for large-size trees, helping them to acclimatise. At that moment the growth processes slow down giving place to a state of dormancy. Contrarily shrubs should be planted in spring since, unlike trees, they don’t withstand the cold so well. An exception is lilac the seeds of which take root best in late autumn, gathering strength for the winter. By the next year, the lilac planted in late autumn will give a maximum accretion.
Trees were planted in places that had already been prepared during the summer. At the bottom, haydite (gravel of burned clay or clay shale aggregate) was laid to protect the roots from decay, water and air. This was covered by geotextiles to prevent haydite from mixing with any water. The next coat was formed by metal netting to which hooks were fastened to fix the lump in the hole and to prevent the tree from falling until the roots strike and strengthen. Later the planting hole was filled with fertile soil mixed with haydite.
After that, the tree trunks were wrapped with a cane ‘blanket’ and the place where major branches sprout was covered in sacking to protect them from gales or sleet. The root ball was covered with woodchips to protect the root system.
The responsibility for the maintenance of the trees is the contractor who will conduct constant monitoring of their condition. Since 2017, the warranty period for each tree has been longer than before and is now three years. All the activities, including replacement of non-established plants, are covered by the contract. Specialists will remove frozen snow and shake it off tree tops, they will add soil to the holes, rip the soil, weed around the trees and cultivate the soil to protect it from vermin and disease. In 2015-2016, over 7,000 trees were planted on upgraded Moscow streets.
