How to Fertilize Flowers Organically

Five Methods:Pick an Organic FertilizerApply an Organic Fertilizer to Spray on Plants

Fertilizing your flower garden with organic materials is considered best by many gardeners. While chemical fertilizers will give you a quick result, over the long term they actually damage a plant's roots. Once this damage occurs, future flowers will be less colorful and sturdy, if the plant survives at all. Organic fertilizers, however, stay in the soil around your flowers longer and won't leave behind any harmful chemicals. Non-chemical fertilizers may take longer to work, but they are better for the health of your soil and flowers in the long run. Here's how you can prepare your garden for organic fertilizers, the organic fertilizer options that are available and how to fertilize flowers organically.
