Culterra Fruit & Flower Fertilizer 6:1:5 (21) - 10kg - Boost Blooms, Fruits & Vigorous Growth

What is Culterra Fruit & Flower 6:1:5?

This is a balanced, high-potassium granular fertilizer with an NPK ratio of 6:1:5 (6% Nitrogen – 1% Phosphorus – 5% Potassium) plus additional nutrients. The formulation is specifically designed to stimulate flowering and fruiting while supporting healthy foliage and strong plant structure. The “(21)” refers to the total nutrient content.

Nitrogen promotes leafy growth, low phosphorus avoids excessive roots at the expense of flowers, and higher potassium enhances flower production, fruit quality, size, colour, flavour, and disease resistance.

Key benefits and uses:

• Encourages abundant flowering & fruiting: Ideal for fruit trees (citrus, mango, avocado, etc.), berries, tomatoes, peppers, roses, flowering shrubs, and ornamentals.
• Improves fruit quality: Larger, sweeter, better-coloured fruits with better shelf life.
• Supports overall plant vigour: Strong stems, lush leaves, and better stress resistance.
• Versatile for South African gardens: Perfect for home gardens, containers, vegetable patches, and orchards. One 5kg bag covers approximately 125m².

How to use it:

• General rate: Apply 40g per m² (about 2.5 tablespoons) evenly around the base of plants.
• At planting: Mix into the soil or planting hole with compost for new plants.
• Established plants: Broadcast as a top/side dressing, keeping it away from stems. Lightly rake or fork into the topsoil and water thoroughly.
• Frequency: Start at the beginning of the growing season and re-apply every 4–6 weeks (or mid-season boost) during active growth.
• Tips: Always water well after application. Combine with organic matter like compost for best results. Safe for use in containers and on most flowering/fruiting plants.

Safety: Wear gloves, avoid inhalation, and store in a cool, dry place. Follow package instructions.

Best time/season to apply in South Africa:

Apply during active growth periods when plants are producing flowers and fruits for maximum benefit.

• Spring (September–November): Prime season across most regions — kick-starts flowering and new growth as temperatures warm.
• Summer (December–February): Continue applications for sustained fruit development, especially in summer-rainfall areas before or during rains.
• Early Autumn (March–April): Good for a final boost on late-season crops or to strengthen plants before winter.

In summer rainfall regions (Gauteng, KZN, etc.), align with the rainy season start. In winter rainfall areas (Western Cape), focus on spring and autumn applications. Avoid heavy feeding in mid-winter dormancy or extreme heat without watering.

This fertilizer is a trusted choice from Culterra for gardeners wanting bigger harvests, more blooms, and healthier fruiting plants. Grow more flowers. Harvest more fruit.
