Spindly growth occurs when one plant receives a great amount of sunlight, while the other would develop as a deformed one, due to lack of sunlight and other natural resources needed for photosynthesis.
Rhizoctonia solani root rot on corn roots, magnified 0.63X. Damping off can be prevented or controlled in several different ways. Sowing seeds in a sterilized growing medium can be effective, although fungal spores may still be introduced to the medium, either on the seeds themselves or after sowing (in water or on the wind).
The fungus forms after the seeds have set but while they are still green and it is potentiated by high humidity. Infected areas are brown to black in color, and as the disease spreads the kernels may become shriveled. Occasionally the infected areas have a reddish tinge. [3] Some authorities [3] make a
Dark brown or black colors typically indicate that the soil has a high organic matter content. [4] Organic matter coats mineral soil particles, which masks or darkens the natural mineral colors. [1] Sodium content also influences the depth of organic matter and therefore the soil color.
Blackheart is a non-parasitic disease of the fruit of cultivated plants, such as tomatoes, that causes them to rot from the inside. External signs of the disease may or may not be present. The internal blackening develops in plants exposed to environmental pathology such as drought conditions or poor soil.

Mechanical elimination of small weed seedlings in the garden is done by stirring the surface of the soil to uproot and bury the seedlings. This can be done with a long-handled hoe that only works at the surface of the soil, such as a light draw hoe, a stirrup hoe, or a scuffle hoe. Weeding can also be done with a wheel hoe outfitted with sweeps.
Partially shelled popcorn seed saved for planting. In agriculture and gardening, seed saving (sometimes known as brown bagging) [1] is the practice of saving seeds or other reproductive material (e.g. tubers, scions, cuttings) from vegetables, grain, herbs, and flowers for use from year to year for annuals and nuts, tree fruits, and berries for perennials and trees.
