Liquids that make plants grow faster include commercial liquid fertilizers, organic liquid extracts such as kelp and fish emulsions, compost tea and manure fertilizer. Commercial liquid fertilizers are complete and provide essential nutrients, such as phosphorus, potassium and nitrogen.Continue Reading
The nutrients in liquid fertilizers are released at a faster rate than those of dry fertilizers and are more quickly absorbed. They are applied directly at the base of the plant.
Organic liquid extracts, such as kelp and fish emulsion, contain micronutrients that work by fertilizing and conditioning the soil. Fish emulsion can be used as a spray applied directly to the leaves of the plant. It helps to promote vigorous growth and contains nitrogen that is easily absorbed.
Compost tea is made by steeping compost in water for a period of three to four days. The liquid “tea” is then applied either to the soil or directly sprayed onto the leaves of the plant. Compost tea helps to suppress plant diseases and improves the nutritional quality of the soil.
Manure can also be mixed with water and left to steep for a period of one month. The liquid is then diluted before applying at a ratio of 1 cup to 1 gallon of water. Manure is a slow-release fertilizer, promotes plant growth and is a good all-round garden food.Learn more about Botany
