You definitely can give plants too much fertilizer - although it depends on the type of fertilizer as to what the consequences are. Too much fertilizer will poison the plants and make them either die or become sickly and more easily attacked by diseases and pests. Most granular and liquid fertilizers are basically salts and when they become concentrated in a solid or liquid form a burn can occur.

Some weed-and-feed fertilizers actually work by overstimulating the growth of the weeds so that their growth exceeds the ability of their roots to supply water and nutrition once the fertilizer is used up - thus killing the weed. Too much fertilizer can cause the same problem in desirable plants including lawn grass.

What plant fertilizer works best on sunflowers?

Sunflowers benefit from a balanced fertilizer with a higher concentration of phosphorus to promote strong root development and flowering. A general-purpose fertilizer with an N-P-K ratio of 10-10-10 or similar should work well for sunflowers. Apply the fertilizer according to the manufacturer's instructions, usually in the spring before planting and then throughout the growing season as needed.


How much food do you give to a water plant?

Water plants usually require a small amount of food. A general guideline is to use a liquid fertilizer specifically formulated for aquatic plants and follow the recommended dosage on the label. Overfeeding can lead to nutrient imbalance and algae growth in the water.
