Some plants have aromatic foliage and stems in addition to or rather than aromatic flowers. Rosemary and scented-leaf geraniums are favorite examples. Healthy Soil Promotes Healthy Growth Fragrant flowers can be grown almost anywhere in the garden, window boxes or planters. Wherever they are grown, there must be a proper soil mix to ensure healthy, productive, aromatic plants. When water enters the soil, air is forced out.
Organic matter helps clay soil to drain and sandy soil to hold more moisture.
Because of its importance in soil health, organic material should be added each year to garden soil. A good source of organic material is a compost pile. Adding compost to the soil will help improve soil texture, increase water infiltration and provide needed nutrients. Minerals are also important for healthy plant growth. The right mix of nitrogen, phosphorous and potash is vital to fragrant floral growth.
