Flowers planted in containers allow you to bring the bright color, scent and garden green of perennials and annuals to nearly any spot in or around your home. When planting flowers in pots, the most important consideration is how the pot will be viewed and where it will be placed. A pot set on an outdoor dining table that will be viewed from every angle is planted differently that one intended to sit up against a porch or patio column. Flowerpots look most attractive when three or more plants of varying height, complementary color and contrasting texture are used.
Determine where you'll put the flowerpot and whether it will be viewed in the round or from one predominant angle. If viewed from one angle, determine the front and the back of the pot. This orientation will guide your plant placement.
Fill the pot halfway will fresh, sterile potting mix with a single application of balanced slow release granular fertilizer such as a 10-10-10 mixed into the soil.
Place your tallest plants into the pot first. Place them in the center of the pot for when they will be viewed from all angles or in the back of the pot when viewed from predominantly one angle.
Set medium height and spread plants in the pot either around the central tall plants or in front and flanking the tall plants in back.
Put the lower height and trailing plants around the outer perimeter of the pot or draping over the front of the back to front planted pot.
Fill in the remaining potting soil around the plants, using your fingers to push it into the crevices between plants and ensure good root to soil contact. Leave a 1/2-inch lip of the pot free from soil to act as a watering catch.
Drench the pot several times with water and add more soil if any air pockets collapse. Keep the soil evenly moist at all times.
