WIn agriculture and gardening, a cloche is a covering for protecting plants from cold temperatures. The original form of a cloche is a bell-shaped glass cover that is placed over an individual plant; modern cloches are usually made from plastic. The use of cloches is traced back to market gardens in 19th century France, where entire fields of plants would be protected with cloches. In commercial growing, cloches have largely been replaced by row cover, and nowadays are mainly found in smaller gardens.

WFlat beans, also known as helda beans, romano beans and "sem fhali" in some Indian states, are a variety of Phaseolus coccineus, known as runner bean with edible pods that have a characteristic wide and flat shape. Flat beans are normally cooked and served as the whole pods, the same way as other green beans. Like many other types of bean they can also be dehusked or shelled and the whitish seeds dried and stored, but there is no incentive to grow them for this purpose as higher-yielding bean varieties are available.

WA growbag is a large plastic bag filled with a growing medium and used for growing plants, usually tomatoes or other salad crops. The growing medium is usually based on a soilless organic material such as peat, coir, composted green waste, composted bark or composted wood chips, or a mixture of these. Various nutrients are added, sufficient for one season's growing, so frequently only planting and watering are required of the end-user. Planting is undertaken by first laying the bag flat on the floor or bench of the growing area, then cutting access holes in the uppermost surface, into which the plants are inserted.

WA Leaf Spot is a limited, discoloured, diseased area of a leaf that is caused by fungal, bacterial or viral plant diseases, or by injuries from nematodes, insects, environmental factors, toxicity or herbicides. These discoloured spots or lesions often have a centre of necrosis or cell death. Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves.
W"Liners" is a horticultural term referring to trays of very young plants, usually grown for sale to retailers or wholesalers, who then grow them to a larger size before selling them to consumers. Liners are usually grown from seed, but may also be grown from cuttings or tissue culture. They are grown in plastic trays with many "cells," each of which contains a single liner plant. Liners will typically range in size from a 36 cell tray up to a 288 cell tray. The most common size used in commercial nurseries is between 50 and 72 cells. The term "liner", is typically used for perennial, ornamental, and woody seedlings. Annuals in this form are usually referred to as plugs.

WMr. Stripey is a type of heirloom tomato with unusually small leaves and a mix of a yellow and red color that can fool some growers into thinking they are picking an unripe tomato. Under good conditions in size, shape and internal structure it may be considered a "beefsteak".Tigerella is generally smaller than the Mr Stripey variety and the colors are less defined, they actually are two distinct different heirloom varieties. Tigerella isn't as sweet or "low-acid" as the Mr Stripey variety either. Like other heirlooms, Mr. Stripey has an appearance that differs considerably from other tomatoes. In coloration it is generally somewhat more yellow near the stem and more red towards its underside, with gentle stripes of red and yellow blending into each other along the sides. This coloration may extend into the interior of the fruit, which tends to be more yellow than red.

WPark Road Allotments are allotments in Old Isleworth. They were managed by the local council who rented the land from the estate of the Duke of Northumberland. The allotments are recognised as an asset of community value but, in 2015 when the 100-year lease expired, they were threatened by redevelopment by the Duke, who proposed to build flats and houses upon the site while providing allotment space in nearby Syon Park. These plans were opposed by local parties such as the Isleworth Society and, on 20 June 2017, the planning committee of Hounslow council rejected them. The matter was then appealed and a public inquiry started on 9 October 2018.
WPlantlets are young or small clones, produced on the leaf margins or the aerial stems of another plant. Many plants such as spider plants naturally create stolons with plantlets on the ends as a form of asexual reproduction. Vegetative propagules or clippings of mature plants may form plantlets. An example is mother of thousands. Many plants reproduce by throwing out long shoots or runners that can grow into new plants. Mother of thousands appears to have lost the ability to reproduce sexually and make seeds, but transferred at least part of the embryo-making process to the leaves to make plantlets.
WPotato leaf (PL) is one of two major types of leaves which tomato plants exhibit. The other type is referred to as "regular leaf" (RL). Simply stated, potato leaf tomato plants have a smooth leaf edge when compared with the serrated edge of the regular leaf. The shape is oval and may feature notches separating large lobes. Its color is dark green.

WRhubarb forcers are bell shaped pots with a lid covered opening at the top. Used to cover rhubarb to limit photosynthesis, they encourage the plant to grow early in the season and also to produce blanched stems. The pots are placed over two- to three-year-old rhubarb crowns during winter or very early spring. Once shoots appear the lid is taken off, causing them to grow towards the light.
WRing culture is a method of cultivating tomato plants. Tomato plants are grown in a bottomless pot, a "ring", and the pot is partially submerged in a tray of water. It is perhaps best described as Two Zone Culture. The gardener aims to have one layer or zone of roots in a container and a second layer or zone of roots in some permeable material like gravel, sand or coarse ashes below. Ring culture forces the plants to develop two root systems: one which will absorb the nutrients contained in the soil and another which will absorb the water from the tray. It enables a gardener to grow an excellent group of tomatoes in shallow soil. It is used in greenhouses largely for tomatoes and enables a heavy crop to be grown above, for instance, a gravel path or an ash bed.
WA root ball is the main mass of roots at the base of a plant such as a shrub or tree. It is of particular significance in horticulture when plants are repotted or planted out in the ground. The quality and preparation of the root ball will determine how well the plant will survive this transplantation and then flourish in its new situation.
WA seed germinator is a device for germinating seeds. Typically, these create an environment in which light, humidity and temperature are controlled to provide optimum conditions for the germination of seeds.
WAdolph Strauch was a renowned landscape architect born in Silesia, Prussia, known particularly for his layout designs of cemeteries like Spring Grove Cemetery in Cincinnati, Ohio, Forest Lawn in Buffalo, NY and Oak Woods Cemetery in Chicago, Illinois.

WIn lawn care, thatch is a layer of organic matter that accumulates on a lawn around the base of the grass plants. Thatch is a combination of living and dead plant matter including crowns, stolons, rhizomes, and roots. Grass clippings do not generally contribute to thatch buildup as they can be easily broken down by soil microorganisms. Thatch is composed of about 25% lignin, a complex organic polymer that is highly resistant to decomposition.
WTigerella is a bi-colored tomato cultivar, relatively small, 2 to 4 ounces, and early. Upon maturity the fruit is red with yellow stripes, essentially the same as Green Zebra, except that the fruit is red instead of green, and has a sweeter flavor. The colour occasionally varies, in New Zealand for instance, commercially produced Tigerella is dark crimson red with very dark green stripes.
