Flowers in Planters


Many resourceful gardeners turn a huge variety of containers into suitable, attractive planters for flowers. It's possible to use old half barrels, watering cans, cement molds and wooden boxes to add interest and floral arrangements to the landscape. Planting flowers in planters involves evaluating the condition and drainage ability of the container. Picking a location for the planter ties in directly to the choice of flowers based on sunlight availability. Annual flowers grow perfectly in planters but perennial flowers will grow beautifully in container gardens. Caring for flowers in planters requires vigilance in planting, watering and fertilizing so these container gardens showcase beautiful blooms and foliage.

Planter Types

Planters come in a range of sizes, shapes and colors as well as every design imaginable. Regardless of shape, flowers in planters add a beautiful accent piece to the landscape. Homeowners can match containers to the outdoor color scheme or blend planters into the landscape using wood or concrete. Flowers in planters should be positioned in containers that allow plenty of room for mature root growth. Crowding will stunt foliage growth and possibly limit flower production.


The very first step before planting a single flower requires a careful check of the drainage capability of the planter. Water should not pool inside the planter since roots will rot if left in standing water. Most planters come with drainage holes already punched into the bottom of the container but holes can be easily drilled or poked into the bottom of a planter using a hammer and screwdriver or drill.


Gardeners choose potting soil for use in most landscape planters. This packaged soil can be purchased from the garden center and actually contains little to no dirt at all. Instead, the mixture contains sand, peat moss and an absorbent Styrofoam-like substance called vermiculite. All three encourage moisture retention around seeds and plants. Potting soil creates the perfect base for planters filled with flowering annuals or perennials. This mixture also slowly releases nutrients to the plant roots to boost health and flower quality.


Flowers in planters require very different watering than those planted in garden soil. Potted plants generally dry out quickly and require frequent watering to keep the soil moist to the touch. Flowers in planters should be monitored daily to evaluate the moisture level in the soil. If the potting soil becomes powdery to the touch or looks dry, the flowers should be watered immediately. Remember that planters are a microenvironment in a confined space. Any moisture needs to be provided by the gardener at regular intervals to ensure healthy plants.


Plants expend incredible energy creating buds and blooms. Flowers confined to a planter need more than simply water to thrive and grow. Fertilizer is an absolute must for the flowers in planters. Apply water soluble, all-purpose fertilizer every 2 weeks throughout the growing season to encourage frequent blooms and healthy foliage.
