1、When is the Best Time to Apply Calcium Fertilizer for Greenhouse Cherries?

The optimal periods for applying calcium fertilizer to greenhouse cherries are during the growing season, specifically: before and after bud sprouting in spring, during fruit expansion, and before leaf fall in autumn.

2、Nutrient Management in Sweet Cherries

For inorganic products that are more readily available (urea, calcium nitrate, monoammonium phosphate, etc.) spread the application starting at petal fall up to a month prior to harvest. Excessive N applied close to harvest can reduce coloring and delay harvest.

3、When and how to apply Calcium in cherry trees to get optimum results

After cherries reach 5-8 mm, xylem functionality drops substantially and the concentration of Ca begins to diminish in the fruits due to the dilution effect. As can be seen, the time available to accumulate calcium in them is short, no more than 10 to 15 days (depending upon the cultivation area).

4、Effect of Foliar Calcium Fertilization on Fruit Quality, Cell Wall

Chinese cherry is early flowering and early fruiting, with good adaptability and resistance, high yield, good fresh flavor quality, and both edible value and ornamental value (Guo et al., 2022).

5、Importance of foliar applications of Calcium in pre

Foliar application of Ca has been recommended to reduce splitting and increase fruit firmness, but its efficiency and effects in relation to other practices are discussed. This article summarises some results of foliar Ca in cherries.

Growing Cherries – Fertilizers for Cherries

Calcium uptake is maximized in the spring after full bloom, so Granular Polysulphate in the spring would be a good dry fertilizer choice along tree lines for yield and quality benefits. Calcium is part of the cell wall and key to cell wall strength.

When to Fertilize Cherry Trees: Essential Timing Tips

Fall fertilization prepares cherry trees for winter. It strengthens roots and improves cold resistance. Use a slow-release fertilizer in the fall. It provides nutrients over the winter months. Avoid high-nitrogen fertilizers in fall. They promote leafy growth, which can be damaged by frost.

Optimal Timing for Calcium Fertilization in Sweet Cherries

The optimal periods for applying calcium fertilizer to greenhouse cherries are during the growing season, specifically: before and after bud sprouting in spring, during fruit expansion, and before leaf fall in autumn.

Foliar application of calcium in cherry production

Our perspective, in which consistent results have been evidenced, is to always apply the product concentration per hectoliter, considering a minimum dose per hectare and adjusting the volume of coverage per hectare to the TRV (tree row volume), where we can determine the actual coverage required.

As an important fruit crop, cherries require proper calcium fertilization during cultivation to promote healthy growth and enhance fruit quality. Calcium is an essential microelement for plant development, significantly influencing growth, disease resistance, and fruit characteristics. Below is a detailed guide on the best timing, methods, and precautions for applying calcium fertilizer to cherries, aiding growers in mastering this critical technique.

I. Optimal Timing for Applying Calcium Fertilizer

1. Before Bud Break (Spring): Spring marks the start of cherry trees’ annual growth cycle. Applying calcium fertilizer at this stage boosts new shoot development and flower bud formation. Calcium strengthens the tree’s pest and disease resistance, reducing infections and laying a foundation for successful spring blooming.

2. Post-Bloom: During the flower bud differentiation period, calcium fertilizer improves bud development and fruit setting rates. It enhances fruit sweetness, texture, and overall palatability.

3. Fruit Enlargement Period: As fruits mature, calcium promotes size, yield, and quality. It increases fruit firmness, storage life, and shelf stability.

II. Calcium Fertilization Methods

1. Soil Testing: Conduct soil tests before application to determine calcium levels and pH. Use results to select appropriate calcium sources and dosages for optimal efficacy.

2. Deep Incorporation: To prevent leaching and maximize absorption, apply calcium fertilizer deeply within the root zone. Spread evenly under the tree’s canopy and cover with soil to avoid wind or rain displacement.

3. Timely Top-Dressing: Supplement calcium during key growth stages (e.g., pre-bud break, post-bloom, fruit enlargement) to meet nutritional demands. Adjust dosages based on phenological phases.

III. Precautions

1. Avoid Overapplication: Excessive calcium can disrupt nutrient balance, reduce uptake of other elements, and cause soil salinization. Use recommended rates to prevent imbalances.

2. Combine with Other Fertilizers: Synergize calcium with nitrogen, phosphorus, and organic fertilizers. Mixing with organic matter improves soil structure and microbial activity.

3. Weather Considerations: Avoid applying during rain or wind. Rainwash and wind erosion reduce fertilizer efficiency and increase loss. Choose calm, dry conditions for application.

Strategic calcium application is vital for cherry productivity and quality. By timing applications correctly, using efficient methods, and following precautions, growers can optimize yields, enhance fruit characteristics, and support sustainable agricultural practices.
