Stem (bulb)
It depends on the plant.
One "bulb" per plant, although they are not technically bulbs.
only in the spring! However, plant the bulb in the fall.
Sylvania bulbs are related to plant growing, but in the sense that they are light bulbs used for growing plants rather than a type of bulb which you plant and grow.
Depends on the plant some grow better in darker places but if it needs light go with the sun it's free
Basically a bulb is a modified stem. It contains the stem leaves and flowers of the plant compressed into the bulb. A tuber is a swollen food store with buds or eyes on the end which grow, to form a plant, that lives off the tubers food store until roots grow sufficiently to support it.
Tulips would be one example of a bulb plant. A bulb plant has a large underground base, shaped like a bulb. It stores food so that the plant can go dormant, instead of dying, when conditions are not optimal. In conditions such a snowy weather, the plant will wither away above ground, but the bulb stays alive safe in the dirt. As the weather warms, the plant will grow and erupt back through the soil again.
Plant the bulb in the Autumn at about two and a half times it's depth. There is enough food in the bulb to flower it the first year. feed after flowering to build up the bulb for the next year.
The bulb. It's just like a tulip bulb you might plant in a garden. A bulb is made of modified leaves, so each layer of the onion and its paper are specialized leaf tissue. They are used by the plant as energy storage; at the end of the growing season the plant undergoes die-back where the above ground portion dies and the sugars from it get concentrated in the bulb. The energy stored is used to grow the plant back next season.
