1、Optimizing Fertilization Strategies to Promote Leaf

Using the entropy weight TOPSIS method, it was concluded that optimizing the N, P and K fertilization rate and timing (applying 3–2.5–1.5 g tree−1 of N-P2O5-K2O in May) is a beneficial approach to maximize EEBs and industrial benefits in leaf-use ginkgo plantations in southern China.

2、Combined application of bud and leaf growth fertilizer improves leaf

The present study aimed to establish optimal and actual fertilization for improving ginkgo leaf flavonoids yield and industrial cultivation or management of leaf-harvesting ginkgo in regions with high-temperatures.

3、The Best and Safest Fertilizers for Ginkgo Trees

Orthogonal test results showed that the nine treatments all promoted the growth of Ginkgo, and the formula (N: 400 g·tree−1, P: 200 g·tree−1, potassium (K): 90 g·tree−1) was the most effective.

However, due to limitations in labor and/or cost management, only a few ginkgo plantations use continuous fertilization during the various stages of ginkgo leaf growth, and one-time fertilization remains the most common management measure in current ginkgo plantations.

5、Analysis on High Efficiency Fertilization Strategy of Ginkgo biloba

【Method】An analysis was conducted based on the field investigation of soil fertility in ginkgo orchard and the fertility demand characteristics in different phenological periods of Ginkgo biloba.

Use slow-release or organic fertilizers for balanced nutrition and soil health. Avoid over-fertilization; if it happens, flush soil with water. Late winter or early spring is your cue to fertilize ginkgo trees. This timing aligns with the budding of new leaves, signaling the start of the growth season.

How To Fertilize Ginkgo Trees

Fertilize ginkgo trees in late winter or early spring, just before new leaf buds. Usually, once a year is plenty, but if you think more is necessary, you can feed the tree again in early summer. Don’t fertilize ginkgo during a drought unless the tree is fertilized regularly.

While spring and fall are the optimal times for fertilization, you can apply a light application of fertilizer in the summer if your tree shows signs of nutrient deficiency, such as pale foliage or stunted growth.

The ginkgo tree (Ginkgo biloba) is a precious ornamental species renowned for its unique morphology and vibrant foliage, making it a favorite in landscape design. To ensure healthy growth, proper fertilization is critical. Below are guidelines for selecting and applying fertilizers to ginkgo trees:

1. Selection and Application of Organic Fertilizers

• Farmyard Manure: Rich in organic matter, farmyard manure is composted from animal and plant residues. It provides comprehensive nutrients, including nitrogen (N), phosphorus (P), and potassium (K). Use well-decomposed manure to avoid root burn or pest/disease risks associated with raw or insufficiently fermented materials.
• Compost: Made from organic waste (e.g., kitchen scraps, fallen leaves), compost enhances soil structure, improves fertility, and introduces beneficial microorganisms. Monitor humidity and temperature during decomposition to prevent over-fermentation and nutrient loss.
• Green Manure: Leguminous plants (e.g., clover) fix atmospheric nitrogen, enriching soil organic matter and N content. Choose suitable legumes and control planting density to avoid negative impacts on ginkgo trees.

2. Selection and Application of Chemical Fertilizers

• Nitrogen Fertilizer: Promotes growth, especially in early spring, by stimulating leaf and fruit development. excessive N can lead to excessive foliage growth, reducing photosynthetic efficiency and fruit quality. Use cautiously.
• Phosphorus Fertilizer: Essential for root development, disease resistance, and fruit quality. Apply in autumn to strengthen roots and enhance cold/disease tolerance. Moderate P use improves fruit characteristics.
• Potassium Fertilizer: Enhances leaf growth, fruit quality, and stress resistance. Apply during hot summer months to boost photosynthesis, yield, drought resistance, and disease defense.

3. Fertilization Methods and Techniques

• Base Fertilization: Apply organic fertilizers (e.g., compost, green manure) in autumn by deep-tilling them into the soil. This ensures nutrient reserves for winter and supports spring growth.
• Topdressing: Perform in spring and summer based on tree growth and soil conditions. Use broadcast, furrow, or hole application for efficient nutrient absorption.
• Foliar Spraying: A rapid method to supplement N, P, and K. Apply diluted nutrient solutions during peak growth periods to reduce fertilizer frequency and dosage. Ensure proper concentration and formulation.

4. Key Considerations

• Dosage: Adjust based on tree age and soil fertility. Young trees require more nutrients, while mature trees need controlled applications to prevent over-fertilization.
• Timing: Spring is critical for growth, while summer heat demands reduced applications to avoid nutrient loss or root damage. Autumn P/K applications strengthen cold resistance.
• Application Method: For shallow-rooted ginkgos, use furrow or hole methods; for deep-rooted trees, broadcast or drip irrigation works better. Avoid direct root contact with fertilizers to prevent burning.

Scientific fertilization is vital for ginkgo health. Select fertilizers based on growth stages, soil conditions, and climate. Balance dosage, timing, and methods while monitoring tree responses. Proper management maximizes ornamental and economic value, ensuring thriving ginkgo trees.
