Fertilizing Flower Gardens and Avoid Too Much Phosphorus. ... However, complete fertilizers sold for flowering plants (including roses and bulbs) such as 15-30-50 or 10-30-20 contain higher amounts of phosphorus (the second number) than nitrogen or potassium and are often labeled as “blossom or bloom booster”.

Fertilizers fall into two general categories: organic, or natural, and inorganic, or chemical. ... Natural fertilizers are those formed through decomposition, while chemical fertilizers are manmade or mined. Natural fertilizers improve the texture of the soil and increase the amount of beneficial microorganisms.

Tomatoes planted in minimally fertile soils should be regularly fertilized to keep their N-P-K levels consistent. ... Keeping this in mind, choose a fertilizer that's low in nitrogen levels and higher in phosphorus and potassium. Examples of suitable N-P-K ratios for tomatoes include 8-32-16 and 6-24-24.

The simplest way to distinguish between compost and fertilizer is to remember this: Compost feeds the soil and fertilizer feeds the plants. Fertilizer adds to the soil's nutrient supply, but instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants.
