Up until the early 1990s, most gardeners were suspicious of organic gardening. Synthetic chemicals made in a lab were the fertilizer of choice for growing beautiful flowers. But since that time, agricultural institutions have recommended compost and other natural fertilizers for boosting flower production in home landscapes
A flower is part of a plant’s reproductive organs. Flowers that are pollinated create seeds to produce new flowers. Because of this, a lot of a plant’s energy goes into producing flowers. Fertilizer provides more nutrients for plants to draw on to produce even more flowers. Fertilizers provide the three macronutrients for a flower to grow. Nitrogen promotes plant greenery, potassium encourages overall healthy plants and phosphorous promotes a strong root system.
Synthetic fertilizers are often made in a lab. By contrast, natural fertilizers are composed of carbon material that is made from decomposed living tissue. Much of this living tissue comes from plant material sources. All fertilizers contain some of each macronutrient that plants need to thrive. In addition, natural fertilizers provide a flower with micronutrients, including calcium, sulfur and magnesium.
Organic fertilizer sources may be classified into two categories: stabilized organic material and active fraction. Stabilized organic material is fully decomposed, while active fraction is typically not completely decomposed. In composting terms, the stabilized organic material is known as finished compost, whereas the undecomposed material is known as unfinished compost. Stabilized material is suitable for mixing into the soil or using in containers. Active fraction is used for top dressing. You can also plow active fraction into the soil so that it can finish decomposing well in advance of planting flowers.
Organic fertilizers take several familiar forms. The most common form is compost. Compost is organic material that has been decomposed in a controlled environment to render the nutrients into a usable form quickly. Compost may be made out of almost any organic material, from kitchen scraps to lawn waste to animal manure. Animal manure and other undecomposed compost may also be used in active fraction form as a top dressing. In addition, compost may be soaked in water to transfer the nutrients into the water. This form of fertilizer, known as "compost tea," can be used to water plants that have already been planted.
Using organic amendments in soil has several benefits in addition to adding micronutrients into soil. Organic amendments bind with aggregates to prevent erosion. Organic amendments will also increase both aeration and water retention in soil. Finally, organic amendments will attract worms, beneficial insects and microorganisms that improve soil.
