Bengaluru has trees that flower through the year. Many a time one wonders how they can be a part of that whole system. How easy is it to plant trees and watch it grow? What are the requirements from departments involved? How are plant species selected? How did other citizens and groups go about tree planting?
Tree planting is a big step that needs planning and dedication, the Tree Planting Guide simplifies the process and you could add to one of the city’s trees.
How do we begin tree planting?
Planning is an integral part of tree planting, though the planting process make take a couple of hours and the nurture a few months to a year, the tree is a long-term addition and investment to our environment.
Preparation Study: It would be wise to examine the Comprehensive Development Plan of the area if the tree planting is planned in public spaces. Obtain approvals, if necessary. The proposed area should be studied beforehand to understand layout, soil, water availability, inhabitants and so on. Educate the local people nearby about the planting need, process, schedule and care. Choose the species with care based on its qualities.
Location and Spacing: In its full glory, a tree will have a canopy and roots so before planting consider the space above and below the ground. Do not place tall trees where high tension wires are running overhead and be aware of any underground pipes, cables, sewerage lines, building foundations etc. Avoid places below electric cables except for bushes.
Plant medium sized trees at least 4 feet from each other and bigger ones at 8 feet from each other and 5 metres away from building foundations. Ensure that a grown tree will not obstruct traffic. Covered places are unsuitable for trees, bushes, smaller plants or climbers.
Time: The most suitable time is monsoon between June and September as the land is moist and the rain waters the plants. Moderate temperature and good rainfall are favourable for saplings to grow as they need time to root and acclimatise before summer’s heat and dryness or winter’s freezing temperatures.
Where should we get permission to plant trees, if we are planting around a lake?
If the area is in BBMP limits, you have to approach BBMP’s Forest Cell or local BBMP offices. The authority could even be Forest Department, Minor Irrigation Department, Gram Panchayat etc for permission.
In BDA limit, you need to give a written request to BDA commissioner, who will direct the request to the Deputy Conservator of Forests in BDA. The DCF will forward it to Executive Engineer. The engineer will check whether the lake is properly fenced or not, is the lake is rejuvenated etc. Executive Officer will forward it to the concerned officer who will go to the lake and check the feasibility of plantation. After taking inputs from everyone, the DCF has to approve it.
BDA typically does not give permissions to plant trees if it is not fenced. It is better to get the permissions first and then take up the plantation drive.
How is a tree plantation drive financed?
Sometimes the drives are self-funded by the volunteers. Some companies are willing to spend their CSR money for such initiatives. BBMP can also provide help as required, with proper co-ordination. Alternatively, when BBMP undertakes tree plantation drives, citizens and groups from the area can get involved and help sustain the saplings.
Why is it better to have self-funded / crowd-funded tree plantation drives?
Most tree plantation drives conducted by BBMP so far are known to have been done without taking local people into confidence. Recent submission by the BBMP to court gives a figure of more than 10 lakh trees planted in Bangalore, while even 40% of them have not survived. The money spent in such cases becomes a waste.
Also, when someone finances a plantation drive, they do not want to see it go waste, hence the community will be involved in the protection of the trees planted. The survival rate would improve, while the official expenditure using taxpayers’ money becomes nil.
What do you need when you want to plant a tree?
-
The equipment to dig the pits, like crowbar, mumties, baskets etc.
-
Protective gloves, masks etc for citizen volunteers, if required.
-
Fresh garden soil if the soil is not good
-
Little manure to provide initial nutrition
-
Tree guards – metal or wooden
-
Arrangements to water the plant as required.
How do we go about tree planting?
Method: Pick the number, type and age of the saplings and separate them on the planting day and ensure sufficient watering facilities.
Do not dig holes which are too narrow and too deep as the former don’t have access to sufficient oxygen to ensure proper growth and with the latter the root structure can’t expand sufficiently to nourish and properly anchor the trees. Generally, do not transplant trees deeper than the soil in which they were originally grown. The width of the hole should be at least three times the diameter of the root ball or container or the spread of the roots (in the case of bare root trees) to provide the tree with enough worked earth for its root structure to establish itself.
Preferred pit sizes: Normal plantation: 30X30X30 cm / Roadside plantation: 45X45X45 cm
Planting Pattern: Line, Square, Triangular and Quincunx planting
Care: Care for the saplings until they reach a certain age and height. Saplings 7-10 feet high have been proven to have a higher survival rate. Although lakhs of saplings are planted annually, a lucky few blossom as big trees. Once the rains cease, water the saplings regularly, protect them from cattle, rodents and insects and given manure.
Some examples of tree plantation drives
Treesforfree (TFF) planted 500 saplings on the JP Nagar Ring Road median in 2008-’09 while Let’s Integrate For Environment (LIFE) planted 350 trees at Jadegenahalli in 2008.
Munnekolala lakes group planted 600 trees with the help of funding from United Way of Bengaluru, while the saplings were given by BBMP Lakes Department. This was done on June 14, 2014.
Citizens’ groups in Vidyaranyapura including Corporators gathered and planted 250 trees and 100 flower plants in Narsipura-2 lake on Sunday, June 15, 2014. The Corporator of the ward helped with the permission. Citizens who turned up in large numbers dug the pits and planted the trees. BBMP staff helped the citizens.
SayTrees.org recently planted more than 600 saplings, 8 feet tall and above, more than 20 species, in Kasavanahalli Lake.
Where can we get help?

Which trees can be planted where?
Depending on where the trees are being planted and what additional value of the tree is sought the species needs to be chosen. Local trees that bear flowers and/or fruit that will additionally attract birds and butterflies, and trees that are suited to dryland areas that do not take up much water, or are reasonably resistant to dry spells are ideal to plant.
