Fall Bulbs should be planted as soon as the ground is cool , when evening temperatures average between 40° - 50° F. Ground temperatures reaching 40° - 50° F during fall is most common in cold climates (zones 1-7), generally 6-8 weeks before the ground freezes. However, as long as you can dig and your ground is workable, you can still plant!What is the best light bulb for plants?
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.
