IS FERTILIZING NECESSARY?
Some flowers will bloom in poor soils, but most will benefit from some fertilizer. If your soil needs to be improved, use a low nitrogen fertilizer with a 5-10-10 ratio or add organic matter such as weed-free straw or grass clippings, peat moss, well-rotted compost, or leaf mold. These will enhance soil texture and encourage the growth of beneficial microorganisms. Over fertilizing can promote weeds and lush foliage instead of flowers.
