It shouldn't be the tropics, but the temperature should not fall below 55 degrees F. The best temp to leave the thermostat at is 65 degrees F. Indoor plants literally melt in freezing temps and some can develop leaf mold if left wet and cold.

Botryosporium pulchrum is an ascomycete fungus that is a plant pathogen. It was described by August Carl Joseph Corda in 1840. It causes leaf mold in geraniums.

The sooty mould seems to grow on insect frass. The black leaf mold only affects some varieties. The bacteria Pectobacterium carotovorum subsp. carotovorum can also cause bacterial soft rot and necrosis on the leaves, but causes more severe damage to the related species Pandanus conoideus.

The most effective and widespread method of disease control is to use resistant cultivars. However, only few resistant cultivar to tomato leaf mold are known such as Caruso, Capello, Cobra (race 5), Jumbo and Dombito (races 1 and 2). Moreover, this disease is not considered an important disease for breeding field tomatoes.

The pathogen is likely to grow in humid and cool conditions. In greenhouses, this disease causes big problems during the fall, in the early winter and spring, due to the high relative humidity of air and the temperature,University of Illinois Extension.

Attenuation of Cf-mediated defence responses at elevated temperatures correlates with a decrease in elicitor-binding sites.

The causal fungus of tomato leaf mold may also be referred to as Cladosporium fulvum (Cooke 1883), a former name.

R. floridana is a burrower, preferring a soil, sand, or leaf mold substrate, and spending most of its time underground where it is safe from predators. It surfaces only when heavy rain or plowing forces it to evacuate its burrow. Because of the latter, it is sometimes called thunderworm. When disturbed, it retreats into its burrow tail-first.

Free water is required for Cladosporium fulvum to germinate, spores are unable to infect the perfectly dried leaf. Spores germinate in the leaf surface with free water and humidity with above 85%.High Plains IPM Guide, a cooperative effort of the University of Wyoming, University of Nebraska, Colorado State University and Montana State University.

Centradenia are showy and desirable plants for the garden in subtropical and tropical areas. The plants are grown in rich leaf-mold with sharp, sandy, well-drained soil in partial shade with light. Strong plants are much benefited by liquid manure, and such applications give better colors in both flowers and fruits. Propagate from seed or cuttings.

Kitchen, garden, and other green waste can be recycled into useful material by composting into leaf mold and regular compost. This process allows natural aerobic bacteria to break down the waste into fertile topsoil. Much composting is done on a household scale, but municipal green- waste collection programs also exist. These programs can supplement their funding by selling the topsoil produced.

In Asia, it has been collected from the alpine zone of the Changbai Mountains in Jilin Province, China, and from the provinces of Ōmi and Yamashiro in Japan. The fruit bodies grow in groups on leaf mold, moss beds, or needle carpets during the spring and fall. It is common in forests of fir and beech, and prefers to grow in soil of high acidity.

Endogone is a genus of fungi in the family Endogonaceae of the class Zygomycota. The genus has a widespread distribution, especially in temperate regions, and contains about 20 species. Species of Endogone form underground structures called sporocarps—fruiting structures measuring between a few millimeters to in diameter, containing densely interwoven hyphae and zygospores. Sporocarps are typically found in humus-rich soil or leaf mold, or in mosses.

Symptoms on Tomato Leaf. Photograph provided by Elizabeth Bush, Virginia Polytechnic Institute and State University. The tomato leaf mold fungus is a specific pathogen of tomato plant Lycopersicon, this pathogen has restricted host range (host specific pathogen) that only infects tomatoes, mainly in greenhouses. The symptoms of this disease commonly occurs on foliage, and it develops on both sides of the leaf on the adaxial and abaxial surface.

Additional ingredients used in the mix may include sand, perlite, and grit (for improving drainage) and vermiculite (to increase water retention). Fertiliser (in the form of compost; i.e. leaf mold, bark compost or recycled mushroom compost) is generally not added (or only in very small quantities) for potting soil used for cuttings and seedlings as large amounts of fertiliser are too aggressive for them. It is used for larger plants (larger pots) though.

Flower close-up Atamasco or rain lilies blooming near the entrance to the caves at Florida Caverns State Park Zephyranthes atamasca, commonly known as the atamasco-lily or more generally a rain-lily, is native to the southeastern United States. It grows in swampy forests and coastal prairies, preferring acid boggy soils rich with leaf mold. Following the appearance of broad, grassy leaves in early winter, it blooms in March or April. It has several narrow, linear basal leaves about wide and long.

"The Leaf Mold of Tolkien's Mind" A major influence was the Arts and Crafts polymath William Morris. Tolkien wished to imitate the style and content of Morris's prose and poetry romances, and made use of elements such as the Dead Marshes and Mirkwood. Another was the fantasy author George MacDonald, who wrote The Princess and the Goblin. Books by the Inkling author Owen Barfield contributed to his world-view, particularly The Silver Trumpet (1925), History in English Words (1926) and Poetic Diction (1928).

Mulches also help preserve soil moisture and keep roots cool. Heavy rains, particularly after prolonged dry periods, can also cause roots to split, onion saddleback (splitting at the base), tomatoes split and potatoes to become deformed or hollow. Using mulches or adding organic matter such as leaf mold, compost or well rotted manure to the soil will help to act as a 'buffer' between sudden changes in conditions. Water-logging can occur on poorly drained soils, particularly following heavy rains.

The older leaves are infected first and then the disease moves up towards young leaves. Symptoms of tomato leaf mold appear usually with foliage, but fruit infection is rare. The primary symptom appear on the upper surface of infected leaves as a small spot pale green or yellowish with indefinite margins, and on corresponding area of the lower surface, the fungus begins to sporulate. The diagnostic symptom develops on lower surface as an olive green to grayish purple and velvety appearance, which are composed of spores (conidia).

In the natural environment, the slow decomposition of leaves provides a moist growing medium for young plants and also protects the ground from drying out during periods of low rainfall. It is a significant component of soil organic matter, particularly in temperate deciduous woodland. The slow rate of decomposition allows the plant nutrients bound up in the leaves to be released slowly back into the environment where they can be re-used by plants. Autumn leaves are often collected as part of gardening or farming and kept in pits or containers so that the leaf mold can be used in the garden.

Ghabrial was born in Cairo, where he attended public schools and then the College of Agriculture at Cairo University, gaining a BS in agriculture (1959). He worked at the Egyptian Ministry of Land Reform (1959–61) and then briefly did national service in the Egyptian Army. In 1961, he went to the United States on a government scholarship, and studied in the Plant Pathology Department of Louisiana State University, where he gained an MS (1963) and PhD (1965) in plant pathology, supervised by Thomas Pirone. His MS research was on tomato leaf mold, a fungal disease of tomatoes caused by Cladosporium fulvum (Passalora fulva).
