Use approximately 1 tablespoon (about 15 grams) of a balanced granular fertilizer per plant during the growing season. Liquid fertilizers should be diluted to half the recommended strength to prevent root burn.

Glehnia littoralis Fisch., a perennial herbaceous plant primarily distributed in Northeast, North, and Northwest China, is renowned for its unique medicinal value and flavor. It is commonly used in traditional Chinese medicine to treat symptoms such as lung heat cough and excessive phlegm. Foliar fertilization plays a critical role in enhancing plant health and promoting growth during its cultivation. Selecting appropriate foliar fertilizers is essential for the development of Glehnia littoralis. Below, we explore suitable foliar fertilizers and application methods during the rainy season.

I. Principles for Selecting Foliar Fertilizers

1. Nutrient Composition

• Nitrogen (N): A key element for plant growth, nitrogen supports photosynthesis, strengthens leaf function, and promotes new leaf development.
• Phosphorus (P): Critical for cell division, tissue differentiation, root development, and flower bud formation.
• Potassium (K): Regulates water balance, enhances stress resistance, and facilitates sugar conversion and transport.
• Microelements: Calcium (Ca), magnesium (Mg), etc., which activate enzymes and support physiological processes.

2. Safety

• Use pollution-free fertilizers without hormonal residues or substances harmful to human health.
• Ensure compliance with national standards, avoiding heavy metals and other harmful compounds.

3. Adaptability

• Tailor formulations to Glehnia’s growth habits and soil conditions.
• Choose moisture-resistant, slow-decomposing fertilizers to minimize rainwash effects during the rainy season.

II. Fertilizer Selection and Application

1. Urea

• Function: Rapidly provides nitrogen, stimulating new leaf growth and flowering.
• Application: Dissolve urea in water and spray evenly on leaves before or after rain, avoiding tender shoots and young leaves.

2. Potassium Dihydrogen Phosphate

• Function: Supplies phosphorus and potassium, improving water uptake and enhancing stress/disease resistance.
• Application: Mix with urea to boost phosphorus absorption efficiency.

3. Seaweed Extract

• Function: Rich in minerals and microelements, offering comprehensive nutritional support.
• Application: Combine with other fertilizers for synergistic effects.

4. Humic Acid

• Function: Improves soil structure, increases beneficial microbes, and boosts fertility.
• Application: Use as a base or topdressing fertilizer, often mixed with organic matter.

III. Precautions and Recommendations

1. Avoid Overapplication

• Excessive fertilization may lead to rapid, unhealthy growth and reduced yield. Adjust dosages based on plant needs and soil fertility.

2. Timely Application

• Optimal timing: Before or after the rainy season when nutrient demand is high. Avoid applying during heavy rain to prevent runoff.

3. Monitor Plant Response

• Observe growth closely post-application. Symptoms like yellowing or wilting may indicate over-concentration or high soil salinity. Halt application and take corrective action if needed.

During the rainy season, composite foliar fertilizers containing nitrogen, phosphorus, potassium, and microelements are ideal for Glehnia littoralis. Prioritize nutrient balance, safety, and environmental adaptability to ensure healthy growth. Scientific management of fertilization creates optimal conditions for robust development and high productivity.
