Answer: In a small space it can be helpful to plant at the closer end of the recommended planting range for the various flowers. For instance, if the recommended spacing is 12 to 16 inches apart, use the 12 inch spacing. You should also take care to prepare the soil well so that it can provide nutrients for a denser planting. You might also consider using early bulbs, short growing early season bloomers, mid and late season bloomers to add variety to the display. It is sometimes possible to grow taller plants such as gladiolius up through a shorter planting of, say, petunias to get more display and bloom from a given space. I hope this gives you some ideas.
