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.Know More
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
Coral is not a plant but an animal. Corals are often mistakenly thought to be plants because they are sessile, which refers to their behavior of attaching themselves to the bottom of the ocean.Full Answer >
Trees lose their leaves in the winter as they enter their dormant period in order to protect cells from freezing temperatures. In this stage, they no longer need the food that the leaves produce. Trees respond to changes in available light and begin to form a layer of dead cells in the stem of their leaves, so each leaf breaks from the limb and falls to the ground.Full Answer >
Plants adapt to different climates by modifying their leaves or stems or by shedding their leaves en masse in the fall and going dormant during the winter when there is less water available. They may also have root systems and reproductive strategies that are adapted to the climate.Full Answer >
According to Extension and Outreach at Iowa State University, the most common cause of brown needles on conifer trees is known as winter browning, which can result if the trees have not stored adequate amounts of water in the fall to meet requirements throughout the winter. Photosynthesis continues throughout the winter, a process that requires water. Winter browning is often most visible on the south and west sides of conifers.Full Answer >
