Therefore, pouring soda on plants, such as Classic Coca Cola, is inadvisable. Sprite has almost as much sugar as Coca Cola and is, therefore, not useful as a soda pop fertilizer. It is, however, useful to lengthen the life of cut plants and flowers.

Fertilizer Selection Most gardeners should use a complete fertilizer with twice as much phosphorus as nitrogen or potassium. An example would be 10-20-10 or 12-24-12. These fertilizers usually are easy to find. Some soils contain enough potassium for good plant growth and don’t need more.

Choose any liquids you want, but some suggestions are saltwater, sugar water, vinegar, soda, juice, or even dish soap! Seeds – enough for 3 for each cup, any kind you want to try to grow. Examples of fast-growing seeds are marigolds, sunflowers, beans, and peas.

Why Is Sandy Soil Bad for Growing Plants? The issues with sandy soil are that the increased sand content makes it difficult for the soil to retain nutrients and water. The quartz crystals that make up sand are very fine, and they don’t hold onto nutrients and water like regular soil does.

The major pollutants toxic to plants are sulfur dioxide, fluorine, ozone, and peroxyacetyl nitrate. Sulfur dioxide results primarily from the burning of large amounts of soft coal and high-sulfur oil.
