A dracaena spike plant can be kept alive over winter by transferring it to a pot, using peat-based soil, treating the plant with insecticidal soap and moving the plant indoors. Limit waterings and fertilize the plant only once a month during the winter.Continue Reading
In order to keep a dracaena spike plant alive over the winter, transplant it into a pot and move that pot indoors. Before transferring the plant, fill the pot halfway with well-drained potting soil, preferably a potting mix with a high peat content. Place the plant in the pot, and fill the rest of the space with the potting mix. Eliminate any possible insects or aphids that the plant is harboring by liberally spraying the foliage with an insecticidal soap, and then allow the plant to sit outside overnight.
Once the plant is insect-free, place it inside in a location that receives plenty of direct sunlight. Make sure to keep it away from doors or windows where there are drafts. Water the plant only when the top two inches of soil feel dry. Give the plant necessary humidity by misting it with water twice a week. Fertilize the plant only once a month with a diluted, water-soluble 3-1-2 fertilizer.Learn more about Botany
Chlorine can kill beneficial microorganisms in soil, thereby affecting plant growth; however, most chlorinated drinking water is not concentrated enough to adversely affect plant life in a given area. This is due to the fact that the reproduction rate of microorganisms in the soil is so high that they tend to reproduce again before the plant can be negatively affect by the soil.Full Answer >
There are numerous forms of radiation, including gamma rays, which can hinder the seed germination, root growth and shoot growth of a plant, and ultraviolet, or UV, radiation from the sun, which helps to feed a plant after it has germinated and reached the surface of the soil. However, overexposure to UV-B radiation from the sun can negatively affect the process of photosynthesis in plants, thereby reducing the plant's size, rate of growth and overall quality.Full Answer >
If enough salt accumulates in the soil and into the root zone, it may dehydrate the plant and impede plant growth. Water with a high concentration of salt can prevent the roots from absorbing water from the surrounding soil and may cause stress to the plant.Full Answer >
According to the Department of Primary Industries, the presence of worms improves the quality of the soil and leads to better plant growth. As worms are decomposers, the dead organic material they eat in an area becomes concentrated within their digestive tracts, and they release nutrient-rich casts into the soil.Full Answer >
