This article throws light upon the top four planting schemes for roadside. The schemes are: 1. One Kind of Flowering Trees on Both Sides 2. Two Kinds of Flowering Trees Blooming at One Time on both Sides of Road 3. Two Kinds of Flowering Trees Blooming at Different Time on both Sides of the Roads 4. Shady Trees Only on both Sides of Roads.
Scheme # 1. One Kind of Flowering Trees on Both Sides:
In this scheme only one kind of flowering tree is planted on both the sides of roads. So when trees come in bloom there is riot of colour and roads look elegant for particular period. Different trees in different colours are available for this purpose.
However, for the rest of blooming time roads will look dull. Trees that can be selected are: Cassia fistula, Delonix regia, Cassia nodosa, Cassia jauanica, Lagerstroemia speciosa, Greuillea robusta, Thespesia populnea, Bauhinia variegata, etc.
Scheme # 2. Two Kinds of Flowering Trees Blooming at One Time on both Sides of Road:
In this scheme, two kinds of trees blooming at the same time are planted alternatively on both sides of the roads. The overall effect of two colours is very much pleasing and there is variation in flower colour, shape of trees, leaf size etc. which avoids mono-tonus effect.
Different trees selected are:
1. Greuillea robusta (yellow)—Jacaranda acutifolia (blue)—Greuillea robusta.
2. Cassia fistula (yellow)—Delonix regia (red)—Cassia fistula.
3. Cassia fistula (yellow)—Cassia nodosa (pink)—Cassia fistula.
Scheme # 3. Two Kinds of Flowering Trees Blooming at Different Time on both Sides of the Roads:
According to this scheme two different flowering trees blooming at different time are planted alternately on both sides of the roads. Since the flowering time is different, so one tree will be blooming in one part of the year and the other in another part of the year, hence, road sides will be colourful for longer period. There will not be mono-tonus effect.
Different trees which can be selected are:
1. Bauhinia triandra (purple colour in November)—Spathodea companulata (red colour in end of April)—Bauhinia triandra.
2. Cassia fistula (yellow in May-June)—Jacaranda acutifolia (blue in March-April) — Cassia fistula.
3. Greuillea robusta (Yellow in April)—Bauhinia variegata—Mauve in March— Greuillea robusta.
Scheme # 4. Shady Trees Only on both Sides of Roads:
Shade during summer is required. Therefore, only shady trees are planted on both sides of road which provide coolness during hot part of the day. Suitable trees are: Ficus infectoria, Mimuspos elengi, Alstonia scholaris, Cedrella toona, Swietenia mahagoni, Swietenia macrophylla, Pterospermum acerifolium, Azadirachta indica, Ficus religiosa, Polyalthia longifolia, etc.
