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).
After germination, transport plants to an area with a temperature of 60–70 °F (16–21 °C). Keep under light for at least 12 hours a day. Plant seeds 6 inches (15 centimetres) apart to prevent crowding. Remove deceased plants to promote growth for newly planted ones.
Like many larger farms, she plants cover crops in fields that would otherwise be bare between planting season, along with no-till practices. That keeps organic matter in the soil, helping to ...
It reduces the soil's seed bank or quantity by allowing the weed seeds both opportunity and time to germinate, sprout, and appear before the intended crop is planted. Once the weeds appear, they are easily eliminated by various methods that minimize further soil disturbance. This cycle can be repeated numerous times before planting the crop.
Poppy seeds prefer a brief frost to trigger germination, which is why you sometimes see new poppy plants pop up after a season of cold. By planting your seeds in ice cubes, you're creating an ...
The agency quickly announced a project to artificially plant seedlings from nurseries. But this has raised serious concerns that nursery-grown seedlings can accidentally introduce diseases that ...
Seeds are placed in a medium such as vermiculite, peat, or sand and refrigerated in a plastic bag or sealed container. [1] Soaking the seeds in cold water for 6–12 hours before placing them in cold stratification can cut down on the amount of time needed for stratification, as the seed needs to absorb some moisture to enable the chemical ...
The seeds of many Australian plants and plants from southern Africa and the American west require smoke or fire to germinate. Some plant species, including many trees, do not produce seeds until they reach maturity, which may take many years. Seeds can be difficult to acquire, and some plants do not produce seed at all.
