Rooftop gardening offers an energy-efficient alternative to traditional roofs, providing aesthetic, ecological, and recreational benefits. Key considerations for successful rooftop gardens include roof condition, structural capacity, access, drainage, and plant selection. With Dhaka's rapid urbanization and population growth, rooftop tree plantation is a crucial strategy to enhance air quality, lower temperatures, and combat climate change.

2. Introduction
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
rooftop
 A simple rooftop garden can be created with planting
containers or potted plants.
 This kind of garden is the most common for homeowners to
construct because they are relatively low in cost and easy to
maintain.
 A container garden provides the benefits of reflectivity,
shade, and evapotranspiration.

4. How to do tree plantation on
rooftop
Following are the steps for planning a garden on a rooftop:
1. Consider
• Condition of the Roof
• Structural Capacity of the Roof
• Access to the Roof

5. Consider
 Condition of the Roof:
The most cost-effective time to construct a rooftop
garden is when the roof needs to be replaced or newly
constructed.

6. Consider
 Structural Capacity of the Roof:
Prior to designing and constructing your rooftop
garden, you must first determine if your roof can
support the additional weight of soil and plants.

7. Consider
 Access to the Roof:
An important consideration is access to your roof. In
addition to access for the people who will be
constructing and enjoying your garden.

2. Determine
• Weight of Garden
• Cost

9. Determine
 Weight of Garden:
Weight capacity might limit the number of people who
may access the roof.

10. Determine
 Cost:
Your construction budget should include any needed
structural or safety improvements, irrigation systems,
garden materials, maintenance costs, transportation,
and fees associated with any ongoing professional
assistance and permits.

3. Design
 Special Design of a Green Roof System
 Irrigation
 Drainage
 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.

14. Design
 Drainage:
The water drainage system is an essential component of
any rooftop garden.

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.

16. Design
 Maintenance:
Rooftop gardens must be maintained just like any
garden, for instance by watering or weeding.

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
