What to keep in mind about growing orchids. While each type of orchid has its own care requirements, the following five factors affect all blooms: Light: The plant’s tender leaves can be burned by too much direct sunlight, Yet, insufficient light stunts the growth of certain varieties. Temperature: Orchids that require cooler temperatures can often be well-placed in a low spot near the floor; plants needing warmer environment might do better up on shelves. In general, avoid putting orchids in drafty shelves. Humdity: Orchids love moisture and thrive with frequent misting. Fertilizer: While healthy orchids require plenty of nutrients, too much plant food can cause blackened leaf-tips. Water: It’s usually best to water in the morning so moisture has time to evaporate from the plant throughout the day.
