Growing flowers organically prevents harmful chemicals from getting into the environment and keeps pets and children safe. Although you may worry that without commercial fertilizer and insecticides flowers will fail to bloom or suffer from the ravages of insects and garden pests, your worries are probably unfounded. Soil rich in organic matter releases vital nutrients and produces abundant blooms on lush vigorous growth. Natural remedies made from non-chemical ingredients keep insects and pests at bay.
Select an area for your flowerbed in a chemical-free area. Look for sources of chemical pollutants near the garden. A neighbor's lawn, nearby gardens and commercial farms all pose a risk of contamination when fertilizer or pesticides are applied or the area floods in the spring, bringing runoff to your yard.
Till a garden bed to a depth of 8 to 10 inches in an area that receives full sun for at least six to eight hours a day. Most flowers prefer full sun, but you can also plant flower gardens in shady or partially shaded areas as well.
Spread a 3- to 4-inch layer of well-rotted manure or compost over the soil and work it into the existing soil with a garden tiller or spade. This improves the texture and provides slow-release nutrients to the soil.
Plant flower seeds or seedlings at the recommended depth and spacing for the specific flower. Choose flowers with lighting requirements that meet your sun exposure.
Fertilize the flowers every 10 to 14 days with manure tea or fish emulsion following the recommended application rate. These provide natural fertilizer for your growing plants.
Control insects by hand picking or spraying with a mixture of water and a few drops of dish detergent per quart. Wet foliage thoroughly, making sure to wet the undersides of leaves. This solution repels most insects. Look for natural insecticides in your gardening supply center.
Plant marigolds, nasturtiums and herbs in your garden bed to take advantage of their natural ability to repel bugs.
