In fall 2008 I put new landscaping in, including a hosta/coral bells border and randomly placed red astilbe, sardonna salvia, moonbean coreopsis, and two varieties of asters. Last summer everything survived and thrived. I fertilized twice as instructed and was very happy. This year everything has tripled in size. The salvia is three feet tall and some have already fallen to the ground like an umbrella. They are blocking everything else. Is this because I deadheaded them twice last year for three blooms? I plan to transplant all the salvia to the 'back' in the fall, but do you have any other suggestions?

Since these plants do get quite tall, depending on the variety anywhere from 18 inches to 5 feet, it would certainly be a wise move to place them in the back of the bed. One word of caution--some types do not transplant well and resent disturbance; however, to reduce transplant shock, try cutting back about a third of its growth.The best time to transplant any plant is on a cloudy day or in late afternoon so they have a chance to get settled in before drying effects of the sun set in. Place salvias in the ground at the same depth or slightly below the level they were originally growing.
