I'm giving a potential client an estimate on a full service package. Normally in my package I don't include seasonal color, but this yard already has a small bed by the mail box. since its already there I want to include this into my proposal. This bed is very small, about 20sqft, and it has pansies in it right now. Now I have planted pansies in a couple of my friends lawn just to get a little experience, but none were my reputation was on the line. The pansies I did plant didn't start blooming very well until about 2 weeks ago (I'll blame that on the warm winter). I need to know how many plants I will need per sqft and what do you'll use to amend the soil? I normally use 4in plants. How close should they be planted? Do you'll put anything like pre-emergent in the amended soil to keep weed out of bed? And any other info you'll think I might need to make the job as professional as possible. I need this info to find out my cost so I can get my proposal together. All help is appreciated!
