This document provides important guidelines for caring for bonsai plants, including avoiding choosing plants with large leaves, flowers, or fruits; using styles unsuitable for the species; using blunt cutting tools; unnatural decorations; being impatient for flowers or fruits before shaping; mixing chemicals and fertilizers; keeping bonsai on the ground; tying wire too tightly; retaining wires too long; hard pruning of conifers; heavy fertilization; and unnatural appearances.
Choose plants suitable for the local climate and position them correctly in containers with adequate drainage. Care for bonsai by pruning regularly, providing balanced nutrition with fertilizer, plenty of sunshine, and thorough watering until it drains. Inspect frequently for pests and diseases, and develop a natural-looking design that is well-balanced through constant care and affection.
Planting times for certain crops are February through March and July through August. Seeds can be sown in early spring from February to March or during the summer months from July to August.

This document lists important plant species that are suitable for bonsai, including trees, shrubs, and bamboo. Some recommended species are amaltas, araucaria, babul, bamboo, banyan, ber, bottle brush, bougainvillea, casuarina, cherry, Chinese orange, coranda, cryptomeria, deodar, duranta, excoecaria, gulmohar, hibiscus, ixora, jacaranda, Java fig-tree, murraya, malpighia, oleander, peach, pines, pilkhan, pipal, plum, prosopis, silver oak, tamarind.
Propagation of plants can be done through seeds, cuttings, layering, grafting, or buying seedlings from a nursery. Some plants can also be propagated through collection from seeds or cuttings found in forests or fields.
Selection of plants for bonsai requires choosing species that can thrive in confined spaces with minimal resources. Good options are plants with small flowers and fruits that allow foliage to reduce to a quarter of its normal size, or those bearing flowers on leafless branches. The selected plant must be able to withstand stress from a small pot and low nutrients.
Pruning and trimming helps develop trees into attractive shapes by restricting growth and maintaining a proper balance between roots and shoots. It involves regularly cutting no more than 1/3 of roots or shoots to reduce growth in a controlled manner. Proper pruning techniques help develop good structure and form for trees.
Ideal nutrition for bonsai includes sludge or well rotten cow dung slurry mixed with groundnut, cotton, or neem cake allowed to ferment for a month before diluting. This mixture is given twice a month along with bone meal and single super phosphate, which are also very beneficial.
Growing media for bonsai should be coarse and well-drained to provide water, oxygen, and nutrients. An ideal medium consists of equal parts soil, leaf mold, and crushed brick or sand. The top layer needs sufficient humus, while conifer plants do better in drier soil and fruit trees prefer more humus-rich soil.
This document discusses a landscaping style using cascading plants with variegated star jasmine. Cascade style landscaping features plants hanging over walls or spilling out of containers to create a sense of movement. Variegated star jasmine is recommended as it has green and white variegated leaves and fragrant white flowers that bloom throughout the summer. This combination provides visual interest and fragrance.
This half cascade style bouquet features gardenias as the primary flower. Gardenias are known for their highly fragrant white blooms and waxy green leaves. This elegant floral arrangement is perfect for spring and summer weddings or other celebrations where a fresh, romantic look is desired.
Azaleas are a flowering shrub with delicate blooms that come in a variety of colors. They thrive in partial shade and well-draining soil, and prefer more acidic conditions. When planted and cared for properly, azaleas can add beautiful floral displays and structural framing to gardens and landscapes throughout the spring months.
Structural bonsai style focuses on the overall structure and silhouette of the tree rather than fine details. The goal is to depict the essence of the species through its trunk, branches, and overall shape using minimal pruning and wiring. This style emphasizes the natural growth pattern and proportions that give the impression of an older, mature tree in miniature.
The Japanese maple is a delicate, ornamental tree known for its finely dissected leaves that change color in autumn. It has an irregular, often multi-stemmed structure that branches close to the ground, creating a rounded or vase-shaped silhouette. The Japanese maple is prized in landscapes for its graceful form and seasonal displays of foliage.
Lagerstroemia indica, commonly known as crape myrtle, is an informal, upright plant. It is a deciduous flowering shrub or small tree that is native to eastern Asia. Crape myrtles bloom in summer with clusters of frilly flowers in shades of pink, red, purple, or white.
There are several styles of bonsai trees including formal and informal upright styles, wind swept, slanting, semi-cascade, full-cascade, multiple trunks, group planting, raft, and broom styles as well as rock-grown bonsai.
