Downy mildew |
Initial symptoms of downy mildew consist of dull to bright yellow spots that form on leaves of all ages. With time, these spots can enlarge and become tan and dry. | |
Leaf spots |
Infections of bacterial leafspot start as small, dark specks on leaves. As the disease develops, numerous water-soaked leafspots appear. | |

Decline and dieback may be caused by many factorsand is usually progressive over several years. Trees and shrubs of all ages may be affected, although this disease complex is usually associated with plants that have attained some size and maturityGeneral symptoms of decline and dieback may include pale green or yellow leaves, delayed spring flush of growth, scorching of the leaf margins, small leaves, reduced twig and stem growth, early leaf drop, premature fall coloration. | |
Smut |
Smut causes the internal tissues of the plant cavity to turn black and powdery from the production of black spores produced by funguses. | |
Blights |
Fire blight produces several different types of symptoms, depending on what plant parts are attacked and when. The first symptom to appear, shortly after bloom, is that of blossom blight. In the early stages of infection, blossoms appear watersoaked and gray-green but quickly turn brown or black; generally, the entire cluster becomes blighted and killed The most obvious symptom of the disease is the shoot blight phase, which first appears one to several weeks after petal fall. | |
Rusts |
The rusts are amongst the most common fungal diseases of garden plants. Trees, shrubs, herbaceous and bedding plants, grasses, bulbs, fruit and vegetables can all be affected. Rust diseases are unsightly and often reduce plant vigour. The spore pustules produced by rusts vary in colour, according to the rust species and the type of spore that it is producing. | |

|
Propagation |
It is the process of creating new plants from a variety of sources. |
|
Cutting |
Cutting is when a piece of the stem or root of the source plant is placed in a suitable medium such as moist soil or potting mi. The cutting produces new roots, stems, or both, and thus becomes a new plant independent of the parent. | |
Layering |
It is a method of asexual plant propagation when the rooting of shoots, stem happens on the mother-plant without disconnection. Then the rooted stem, branch or shoot is detached from the parent tree for further propagation. | |
Division |
Plant (usually an herbaceous perennial) is broken up into two or more parts. Both the root and crown of each part is kept intact. | |
Grafting |
Grafting and budding are methods of asexual plant propagation that join plant parts so they will grow as one plant. | |

No pruning at all |
No pruning required at all. | |
Pests |
A destructive insect or other animal that attacks plants. |
|
Mites |
A minute arachnid which has four pairs of legs when adult. Symptoms of injury include flecking, discoloration (bronzing) and scorching of leaves. Injury can lead to leaf loss and even plant death. | |
Thrips |
Tiny, slender insects with fringed wings. They feed by puncturing their host and sucking out the cell contents. | |
Nematodes |
They are multicellular animals with smooth, unsegmented bodies. The nematode species that feed on plants are so tiny that you need a microscope to see them. They are often long and slender, although some species appear pear-shaped. | |
Caterpillars |
Caterpillars, the larvae of butterflies and moths, feed almost exclusively on plants. You will find most caterpillars munching happily on leaves, though some will feed on other plant parts, like seeds or flowers. | |
Scales |
Scale insects are common pests of many trees and shrubs, but not of vegetable plants. Heavily infested plants are often covered with small, disklike or waxy coverings, and underneath each covering is the scale organism feeding on the juices of the plant. | |
Whitefly |
Whiteflies are tiny, sap-sucking insects that are frequently abundant in vegetable and ornamental plantings. They excrete sticky honeydew and cause yellowing or death of leaves. Outbreaks often occur when the natural biological control is disrupted. Management is difficult. | |
Aphids |
Aphids are common pests that can attack a variety of home garden and landscape plants. They are typically found clustering on and plant parts mainly leaves or tips. Aphids seldom kill a plant, but when abundant they remove large quantities of sap, which reduces the vigor of the plant and can result in stunted plant growth. Leaves often become curled. | |
Beetles |
An insect of a large order distinguished by having forewings that are typically modified into hard wing cases . They damage plants either by chewing leaves or making tunnels in the bark. | |
Mealy-bug |
Mealybugs tend to congregate in large numbers, forming white, cottony masses on plants. They feed on stems and leaves of fruit trees and ornamentals. | |
Leaf miner |
Adult Liriomyza are small, active, black and yellow flies. Adult female leafminers puncture leaves and sometimes petals to feed on exuding sap. These punctures eventually turn white, giving foliage a stippled or speckled appearance. | |
Snail |
These slimy mollusks emerge from hiding at night and chew holes in leaves and flowers of many succulent garden plants and fruit. | |

Topiary |
Topiary is training live trees or shrubs by clipping the foliage and twigs to develop and maintain clearly defined shapes. | |
Bonsai |
Bonsai is the art of growing miniature trees. Bonsai as an art is originated from Japan , where plant growth is restricted by training their roots and stems so that miniature trees of high aesthetic value are produced over a period of time. | |
Espalier |
A tree which can be trained to grow flat against a wall or trellis. | |
Specimen |
A plant that is worth planting by itself and is featured in the landscape to its attarctive traits.It can be a glossy leaf, nice bark, long lasting flowering, showy fall color etc. | |
Border plant |
Border and edging plants are used to define areas. | |
Mass planting |
Filling an area with just one or a few kinds of plants spaced close together. Often done to create a bold dramatic effect or to reduce maintenance. | |
Indoor |

Wildlife |
variety of wild and cultivated plants that will attract lots of invertebrates, birds and mammals to the garden. | |
Erosion control |
The primary goal of effective erosion control is to maintain water quality, keep soils in place, to increase infiltration and to reduce runoff. | |

Cut flowers/ Arrangements |

Plant can resist urban conditions meaning less light, less water , high toxic gasses. | |
Reclamation |
Plant populations with the ability to accumulate heavy metals or live on highly acidic and / or polluted soil. These plants will turn the the affected lands for agricultural useage. | |
Intensive Green roof |
The intensive green roof uses planting mediums that have greater than 30 cm depth . This deeper soil allows intensive roofs to accommodate large plants and dramatic plant groupings, pathes, small ponds or basic structures. The net weight on the roof is minimum 300 kg / m2. | |
Extensive Green roof |
The planting medium in extensive green roofs ranges from 10-30 cm. Only plant with drought tolerance and with shallow root system can be used on this type of green roof. The maxium weight on the roof is 100-250 kg/m2. | |
Façade |
Green facades and living walls use plants to cover building walls. Climbing plants used on green facades are either containerised or rooted in soil at ground level. Self-clinging climbers adhere to the building exterior by adventitious roots or self-adhesive pads. | |
