Raising the planting for annuals is kinda hard to do in existing beds.
If I want height........I plant close together...give you an example
Take Impatient.....If I need them low or as low as possible I will plant them 12, 16 or more inches apart.......If I want them taller......I will plant them about 4 inches apart..........Now If I am going for an indiviual grouping and need the size of a shrub from the impatient.....I will take 3, 4 or the entire 6 pack, dig one hole, hold them all together and plant them.......That way I can get impatient as high is a desk (using a desk for reference)
Even though I can achieve different affects depending on plant distance.......the one thing that makes what I want to happen, happen........is Osmocote. A healthy dose right at the base when planting. All I have to do then is step back and watch them grow, and grow during the season.
On a side note.........every one asks me how I get my flower plantings do what they do.......Tell them "trade secret"
