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.
The document discusses a demonstration on Juniper bonsai trees that will take place in Columbia. Juniper bonsai are a popular type of bonsai tree that can be styled and shaped through careful pruning and training. The demonstration will cover basic bonsai techniques for caring for and maintaining Juniper bonsai trees.
This document lists the essential equipments and tools needed for bonsai, which includes a plant, pots of various shapes with drainage holes, a potting mixture of soil, sand and leaf mould, potting sticks, sieves, copper wire of varying thickness, wire cutters, pruning knives and secateurs, and watering equipment like a can and tub.
This document lists important plant species for growing bonsai in hilly areas, including Araucaria, Aucuba, Azalea, Camellia, Chinese hat, Coral tree, Cryptomeria, Cypress, Flame of the forest, Ginkgo, Juniper, Koelreuteria, Maple, Magnolia, Plane tree, Peach, Pines, Podocarpus, Sal, Silver fir, Spruce, Taxus, Thuja, Willows, and Zanthoxylum.
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.

1. CHAPITRE 1. OPTIQUE CLASSIQUE 1.4. LA RÉFRACTION
Fig. 1.14 Le bâton brisé
Comme AH est en réalité égal à sin(®incident) et IG
égal à sin(®r´efract´e), la loi de Snell-Descartes expri-m
ée mathématiquement correspond bien à l'expres-sion
en français donnée par Descartes.
1.4.2 Le bâton brisé
Il existe beaucoup d'exemples où la loi de la ré-
fraction permet d'expliquer correctement ce que l'on
voit. Parmi ceux-ci celui du bâton brisé est intéres-sant
parce qu'il est facile à réaliser. Il s'agit tout sim-plement
d'expliquer le fait qu'un bâton parfaitement
droit se brise visuellement quand on le plonge dans
l'eau comme on le voit sur la gure 1.14.
L'explication est simple. On peut considérer l'ex-tr
émité du bâton. Celle-ci émet des rayons lumineux
dans toutes les directions. Seuls certains de ces rayons
vont parvenir à l'÷il. Mais ceux-ci seront réfractés en
s'éloignant de la normale quand ils vont passer de
l'eau à l'air pour parvenir à l'÷il. En eet, les rayons
passent d'un milieu dense à un milieu moins dense.
Cette réfraction ne sera pas perçue par l'÷il qui va
construire l'image de la partie immergée du bâton en
suivant les rayons virtuels, comme présenté sur la -
gure 1.15. Le bâton parait alors brisé, mais c'est une
illusion.
1.4.3 L'arc-en-ciel
Ce phénomène naturel (voir gure 1.16) étonnant
est en réalité assez facilement expliqué grâce à la loi
de la réfraction et à celle de la dispersion. On sait
que la pluie et le soleil sont impliqués, puisqu'il a gé-

néralement lieu juste après la pluie et quand le soleil
revient. De plus, on sait aussi que le soleil est alors
relativement bas et toujours dans le dos de l'observa-teur.
Ce phénomène possède une composante géomé-
trique et une autre ondulatoire. Nous n'aborderons ici
que sa partie géométrique. Elle implique des gouttes
d'eau en suspension dans l'air. Celles-ci sont sphé-
riques et sont traversées de rayons lumineux comme
le montre la gure 1.17.
On constate que la goutte est traversée par le rayon
lumineux qui subit à l'entrée dans celle-ci une réfrac-tion,
puis se rééchi sur la sa surface intérieure et
enn ressort en se réfractant une seconde fois. A l'ori-
