Classification Description
1. Based on Growth habit Monopodial • These orchids do not make separate new
growths in each season.
• The growth of the axis stops at the end
of each flowering season and continues
in the next season by a newly grown axis.
• Do not have rhizome and where single
stem increases its height throughout the
life period,
Ex. Aerides, Rhynchostylis, Vanda,
Phalaenopsis, etc.
Sympodial • The plant grows continuously in one
direction only and their stems lengthen
from one season to another and produce
aerial roots along their whole length.
• Each new growth produces its own set
of roots
• Stems are generally thickened and
bulbous are named as pseudobulbs
Ex: Cattleya, Coelogyne, Epidenarum,
Laelia and Sophronitis.
• Rhizomes are found only in sympodial
types of orchids and are actually a primary
stem, from which arises the secondary
stem.
2. Based on their Habitats Terrestrial • Grow in soil, Sympodial and perennial

Propagation:
• Division of clumps, keikis, back bulbs and tissue culture plants.
Planting:
• Plant grown to a large clump with 2 or 3 old canes and new shoots, - divided
before repotting. Each division - at least one old cane of two years’ growth, one
new shoot & some new roots.
Harvesting:
• It is best to pick out flowers while they have completely opened because cut
flowers won't last long enough to reach the sellers. Harvesting the spike when 75
per cent of the flowers are open and remaining buds are unopen.
Plant Protection:
• Diseases:
1. Bacterial soft and Brown rot (Ervinia spp.): Application with Foliar spray of

Bonsai
Bonsai
Introduction
• The art of bonsai first originated in China but thrived well in Japan.
• The word bonsai comes from the Japanese ‘bon’ meaning pan, and ‘sai’, a plant.
• It is the skill of shaping and dwarfing trees and shrubs, keeping them minimal replicas
of their original forms by growing them in shallow pots or trays.
Cultivation:
• Bonsai requires specialized techniques and tools for growth and long-term maintenance
in small containers.
• Techniques Include: Leaf trimming, pruning, wiring, clamping, grafting, defoliation, and
deadwood techniques (jin and shari) for simulating age and maturity.
• Young trees can be trained and given an appearance of old age by branch shortening or
training them to grow downward.
Classification of Bonsai:
A. Japanese Size Classification:
B. Bonsai Styles:
➢ Formal Upright (Chokkan):
Straight, upright, tapering trunk with branches thick at the bottom, tapering towards the top.

Deciduous Trees:
• Examples: Acer palmatum, Betula nigra, Fagus crenata, Ginkgo biloba, Malus
spp., etc.
• Varied leaf shapes and colors, distinct seasonal changes.
• Pruning: Pre-bud burst in spring, or specific to autumn for certain species.
Ornamental Shrubs & Small Trees:
• Examples: Azalea, Camellia japonica, Cotoneaster spp., Crataegus spp.,
Jasminum nudiflorum, etc.
• Characteristics: Varied leaf shapes, flowers, and fruits across different species.
• Pruning: Post-flowering, spring, or specific to each plant's growth cycle.
Easy to Grow Bonsai Species:
• Lower maintenance species suitable for beginners: Portulacaria afra, Malphigia
coccigera, Ficus species, etc.
Succulent Bonsai:
• Suitable succulents for bonsai making: Adansonia digitata, Adenium obesum,
Crassula ovate, etc.
Techniques for Growing Bonsai:
• Pruning: Regularly done, mainly in the tree's upper parts during March and
September to encourage inner growth.
• Pinching: Reduces leaf area for artistic shape, but excessive pinching can lead
to wilting.
• Root Pruning: Essential during transplanting to maintain proportion and prevent
roots from bulging out.
• Wiring:Crucial for training bonsai trees; copper wire is pliable and used to bend
branches.
• Wire is wound around the trunk and branch but needs rewiring every six months
to prevent bark injury.
• Defoliation: Technique to promote new, smaller leaves; done on deciduous and
broad-leaved species
Bonsai Containers:
• Selection: Containers should be proportionate to plant growth, durable, and
visually appealing. Shape (round, oval, rectangular) depends on the tree style.
• Preference: Unglazed containers for better soil aeration; natural colors are
favored.

Garden Style
Garden style typically refers to the design and layout of a
garden, focusing on the overall theme and aesthetic choices
that create a specific atmosphere. There are various garden
styles, each with its own characteristics and elements. Some
popular garden styles include:
1. Formal Garden
• Symmetrical garden
• If there is a plant on the left hand side of a straight
road, a similar plant must be planted at the
opposite place on the right hand side i.e., mirror
image of each other.
• Square, rectangular shaped and roads cut at
right angles.
• It has a sort of enclosure or boundary.
• Flower beds are arranged in geometric designs.
• The arrangement of trees and shrubs is necessarily
geometrical and kept in shape by trimming and
training.
• Other features like fountains, water pools, cascades etc. are
used for further attraction
Examples:
Mughal Garden:
➢ Developed by Mughals in India.
➢ Special Features: Mostly square and rectangular in shape
➢ Architectural features like bird baths and fountains were
established.
➢ High walls with huge wooden gates, studded with pointed
iron spikes
➢ Artificial terraces mainly 8 in numbers.
➢ Running water source like canal, stream, ponds etc.
➢ Baradari:Masonry feature with permanen roof and 12 doors
➢ Tomb Monuments: Taj Mahal in Taj Garden
Persian Garden :

➢ Massive flight of marble stairs, decorative
urns, fountains in combination with stone
sculpture.
French Garden
➢ Developed by “Le-Notre”
➢ Based on idea of “How to think big”
➢ He designed gardens at extensive scales.
2. Informal garden
• This style reflects naturalistic effect of total view and
represents natural beauty.
• It is contrast to formal style.
• Plan is asymmetrical according to the land available for
making the garden.
• Smooth curvaceous outlines are more appropriate.
• Water bodies are more irregular in shape.
• Features such as hillocks, water falls, lakes, islands,
cascades, rocks, shola and rustic hutments are
provided to create rural effect.

LANDSCAPE GARDENING
Introduction
• Landscape gardening isn't just about creating visually pleasing surroundings, It's a
reflection of historical and natural elements shaped by human activities over time.
• By incorporating natural components like landforms, trees, shrubs, and water
features, landscape gardening aims to harmonize with the environment.
• it plays a crucial role in environmental improvement by mitigating pollution effects,
reducing heat, noise, and wind impacts.
➢Initial Approach: Utilize available space wisely, maintaining the natural topography.
➢Axis: Imaginary line around which the garden is balanced, often featuring a central
focal point or attraction.
➢ Background: The backdrop of a garden, whether walls, trees, or hedges, should
complement rather than distract from the main garden features.
➢ Contrast: Introducing variety in forms, textures, or colors helps break visual
monotony and enhances interest.
➢ Balance/Proportion: Achieving equilibrium among different garden components
while avoiding overcrowding for a harmonious look.
➢ Focalization: Establishing a focal point that draws attention but doesn't dominate
the entire landscape, often enhancing the entrance or a specific area.
➢ Simplicity: Keeping the landscape design uncluttered and straightforward while
allowing complexity through thoughtful design elements.
➢ Repetition: Repeating specific features in a manner that creates rhythm and unity
while avoiding monotony.
➢ Rhythm: Creating visual harmony through carefully designed lines, patterns, and
repetitive elements.
➢ Variety: Introducing diversity through contrasts in color, form, and texture to maintain
visual interest.
➢ Unity: Ensuring that all landscape elements work together cohesively to create a
unified and aesthetically pleasing space.
➢ Space and Divisional Lines: Design gardens to appear larger by maximizing open
spaces like lawns and limiting peripheral plantings.
➢ Light, Time, Tone, and Color: Use color schemes wisely, leveraging masses of
single colors for a softer, appealing tone.
➢ Mobility and Style: Introduce movement through changing foliage, flowering
annuals, and attracting birds and butterflies.
