How to Fertilize Spathiphyllum: Mainly Nitrogen Fertilizer with Phosphorus and Potassium Fertilizer as Supplements (Soil and Water Culture)
There is a well-known saying among farmers: "A plant is as good as its fertilizer." Plants need to be fertilized during their growing and flowering stages, so proper and effective fertilization can make the plant grow better. Spathiphyllum is a large, ornamental leaf plant, and fertilization is necessary in its cultivation. How to fertilize Spathiphyllum? Generally, soil and water culture are the main methods, and let me introduce them to you.
1. -- Soil Culture Fertilization --
To make Spathiphyllum grow better when fertilizing, it is important to understand its growth habits. As Spathiphyllum is a plant that likes fertilizer, it is necessary to fertilize it properly to ensure the plant can fully absorb the fertilizer, promoting lush growth and vibrant flowers.
Spathiphyllum grows very fast, so appropriate fertilizer should be applied during the growing period. Generally, a compound fertilizer of nitrogen, phosphorus, and potassium is most suitable, with 1-2 sprays per month. Nitrogen fertilizer promotes cell division and lush growth. Phosphorus fertilizer promotes root growth, and potassium fertilizer regulates the osmotic pressure of cell sap, reducing water loss.
During the summer, Spathiphyllum can be fertilized every half month with decomposed soybean cake water, usually dominated by nitrogen fertilizer. In autumn and winter, decomposed liquid fertilizer can be applied once a month, with a focus on applying thin and frequent fertilizers. Be careful not to pour the fertilizer into the leaf axil to avoid root rot.
When applying foliar fertilizer to soil-cultured Spathiphyllum, it is advisable to loosen the soil a bit to allow the fertilizer to quickly渗透 and promote root absorption. Foliar fertilizer can be sprayed with a 2% ferrous sulfate solution every half month, making the Spathiphyllum leaves larger, thicker, and greener.
2. -- Water Culture Fertilization --
Fertilization for water-cultured Spathiphyllum is relatively simple. Generally, fertilization is done during water changes. For example, after changing the water, a small amount of special water culture nutrient solution can be added, but be careful not to add too much, and do not add nutrient solution before new roots have formed.
When choosing foliar nutrient solutions, fertilizers like urea and potassium dihydrogen phosphate that dissolve easily are used for foliar fertilization. The Ruifeng special fertilizer for flowers sold in the market is comprehensive in nutrition and can promote lush growth of the water-cultured Spathiphyllum, with more flowers and longer blooming periods.
3. -- Fertilization Precautions --
Since the stems and leaves of Spathiphyllum have a certain toxicity, whether in water or soil culture, it is important to avoid direct contact with the toxic parts during fertilization. Otherwise, it may cause itching and swelling of the skin, so it is best to wear protective gloves during fertilization for safety.
The above information on how to fertilize Spathiphyllum, mainly with nitrogen fertilizer and phosphorus and potassium fertilizer as supplements, and the methods of soil and water culture, are provided as reference suggestions.
