Roadside trees along the Ponghwa Street are being replaced with trees of good species.

On the roadside lawns, flowering plants are being planted in the front and such ever-green trees as thuja and juniper in the rear to present a three-dimensional effect.

The median islands of the Hyoksin, Kwangbok and other streets are also garnished with plants.

Nurseries under the Ministry of Urban Management, Pyongyang City Greening Company and district horticultural stations supply trees and flowering plants of good species.

Horticultural scientists and technicians are also playing an important part in the campaign.

A nation-wide campaign for land management is conducted in the country in every spring.
