Rooftop gardening is an attractive and energy-saving
alternative to a conventional rooftop. Besides the decorative
benefit, roof plantings may provide food, temperature
control, hydrological benefits, architectural enhancement,
habitats or corridors for wildlife, recreational
opportunities, and in large scale it may even have ecological
benefits.
3. How to do tree plantation on

A simple rooftop garden can be created with planting
containers or potted plants.

maintain.
A container garden provides the benefits of reflectivity,
shade, and evapotranspiration.

Selection of Plants and Growing Media
Maintenance
12. Design
Special Design of a Green Roof System:
A complete green roof consists of many layers.these
layers mimic the conditions found in nature,
creating an environment suitable for plant growth.
13. Design
Irrigation:
The City encourages landcaping with native plants as
an environmentally beneficial garden design. You
should plan for the need to supplement rainfall with
irrigation.
15. Design
Selection of Plants and Growing Media:
Since natural soils are heavy, particularly when wet,
rooftop gardeners typically use lightweight growing
media consisting of high-quality compost and recycled
materials.
17. Advantages and needs of tree
plantation on rooftop
As we all know that people from rural areas of Bangladesh
moving into Dhaka for better living, jobs, education and many
more things. Dhaka is now highly populated city and the rate of
people entering into the city at the rate of 5lakh a year. As our
city is highly populated and there is less space available where
we can plant trees, all we can do is use our rooftop to plant
trees.
18. Advantages and needs of tree
plantation on rooftop
The advantages of planting of trees on rooftop are as
follows:
Plant gives us the most important thing such as oxygen
and they take away harmful gas such carbon dioxide.
Building and surrounding area’s beauty will be more
enhanced.
19. Advantages and needs of tree
plantation on rooftop
Plant will help to lower temperature during summer
and help to maintain cold temperature during winter.
20. Impact of rooftop tree plantation
Dhaka is one of the fastest growing megacities and one of
the most densely populated cities in the world. It covers an
area of 1353 sq. Km where Dhaka City Corporations cover
276 sq. Km. Rapid declines in green areas of Dhaka city, for
allowing built forms are contributing to ever increasing
carbon emission issues.
Roof gardens can actually save electricity and impact of
climate change by reducing the cooling demand for
comfort.
21. Conclusion
Trees are very important for our environment. For
every living being, trees are needed in everyway.
Trees are major element of getting oxygen and
food. But trees are being cutting down for
urbanization, making furniture and many more.
As a result the environment of the city become
imbalanced. But we can overcome this problem
with planting trees on roof top
