Vineyard Fertilizer Program for South Africa

Optimized liquid fertilizer program for vineyards to support vine growth, flowering, fruit set, and high-quality grape production

Key Growth Stages of Grapevines

Grapevines require balanced nutrition throughout the growing season to support vine growth, flowering, fruit set, and berry development. Proper nutrient management during each growth stage helps vineyards achieve strong vine health, improved fruit quality, and consistent yields

Bud Break

The growing season begins when dormant buds start to open and new shoots begin to develop. Adequate nutrients at this stage support early vine growth and healthy leaf formation.
Shoot Development

Rapid vegetative growth requires nitrogen, magnesium, and micronutrients to support strong shoots, leaf expansion, and efficient photosynthesis.
Pre-Flowering

Balanced nutrition helps prepare vines for flowering and improves the potential for successful fruit set.
Flowering and Fruit Set

Micronutrients such as boron and zinc support pollination and berry formation, helping vineyards achieve better fruit set.
Berry Development

During berry growth, potassium and other nutrients support fruit size, sugar accumulation, and overall grape quality.
Ripening

Balanced nutrition during ripening helps improve grape color, flavor, and overall fruit quality before harvest.

Example MaxGrowPlus Vineyard Feeding Program

Below is a simplified example of a foliar feeding schedule used in vineyard production. The program may vary depending on soil type, grape variety, and climate conditions, but demonstrates the typical nutrient progression from early vine growth through flowering, berry development, and ripening.
