Many Bangaloreans are concerned about the reducing green cover in the city. What can you do? Plant trees of course! Here is how to go about planting trees.
How do I go about it?
Preparation Study: The proposed area should be examined beforehand to understand layout, soil, inhabitants and so on. Educate the local people nearby about the planting need, process, schedule and care. Obtain approvals, if necessary. Choose the number, type and age of the saplings and separate them on the planting day and ensure sufficient watering facilities.
Spacing: Before planting consider the space above and below the ground. Do not place tall trees where high tension wires are running overhead. 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.
Location: Plant along the road or on any private land but with local support. Avoid places below electric cables except for bushes. 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 – September as the land is moist and rain waters 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.
Method: 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
• Bamboo plantation: 45X45X45 cm
• Rubber plantation: 75X75X75 cm
Planting Pattern: Line, Square, Triangular and Quincunx planting
Care: Care for the saplings until they reach a certain age and height. 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 give manure.
What trees can I plant?
Many tree planters in Bangalore quote retired forest officer S.G Neginhal’s book on urban forestry as having an excellent list of trees suitable for various locations in urban regions – residential lanes, big roads, parks, schools, etc. Have a good mix of indigenous flowering, fruit and other trees in residential areas. Apparently, there are about 200-300 natives trees in India but obtaining their saplings is challenging with many nurseries having unsuitable foreign species.

Where can I plant trees?
As per the Karnataka Forest Department (KFD) and BBMP, no permission is required for planting trees as long it does not interfere with sanitary lines/road expansion, electric lines including parks and so on.
Do a pre-planting survey, contact BBMP to plant in public places. If the planting event is in private area like schools, offices or apartments, discuss with concerned authorities for office layout, building expansion details and other concerns. ⊕
