National Tree Fair The initiative was taken by the Prime Minister of Bangladesh, Sheikh Hasina. This fair was introduced to encourage the mass people to plant trees and promote gardening. In this hostile era of global warming, the importance of tree planting is inevitable. This fair has a duration of 30 days and takes place at Agargaon, Dhaka – the same place as Dhaka International Trade fair. About thousands of nursery owners participate in this fair to sell their plants. Thankfully, the response is also overwhelming. The busy urban people buy some time to visit the fair and purchase mostly the rooftop plants. Even, some are also fond of interior plants to enhance the beauty of their home.
