Fluorescent Lights. Fluorescent lights come in different spectrums. While white light or daylight tubes seem light the best choice for plants, they are less effective than warm-white or cool-white fluorescent tubes. Cool spectrum tubes produce light mainly in the blue range and are good for the vegetative growth phases of plants.When should bulbs be planted?
Get the Timing Right. Spring-blooming bulbs, such as tulips and daffodils should be planted in September or October, when the soil temperatures have cooled. Summer-blooming beauties such as dahlia and gladiolus are best planted in the spring, after all danger of frost has passed.What should I plant in the fall?
Spring may be special, but fall is fine for planting. Turfgrass, spring-blooming bulbs, cool-season vegetables, perennials, trees, and shrubs can all be effectively planted in the fall. Fall has distinct planting benefits. Autumn's cooler air temperatures are easier on both plants and gardeners.
