Good Fertilizer for Pomegranate Plants: Feed for Fruit, Flowers & Health

Pomegranate plants are prized for their bright red blooms, glossy foliage, and nutrient-rich fruit. But to grow strong branches and juicy pomegranates, you need a good fertilizer for pomegranate plants that supports both flowering and fruiting stages. Whether you’re growing them in-ground or in pots, consistent feeding with the right nutrients makes all the difference in fruit size, yield, and plant longevity.

How Pomegranate Plants Grow

Pomegranates (Punica granatum) are deciduous shrubs that thrive in hot, dry conditions with full sun. In Australia, they grow well in regions like WA, SA, VIC, and inland NSW. Their growth stages include:

Spring: Bud break and vegetative growth
Late Spring to Early Summer: Flowering and fruit set
Summer to Autumn: Fruit development and ripening
Winter: Leaf drop and dormancy

Each stage requires different nutrients. A good fertilizer for pomegranate plants provides essential macronutrients—especially nitrogen, phosphorus, and potassium—at key growth periods to improve flower retention, reduce fruit cracking, and increase sweetness.

What Pomegranates Need from Fertiliser

Nitrogen: Promotes strong shoot growth and leaf health
Phosphorus: Supports flower and root development
Potassium: Improves fruit formation, colour, and sugar levels
Micronutrients: Zinc and boron help prevent fruit deformities and improve flower fertility

Without a good fertilizer for pomegranate plants, the tree may suffer from yellowing leaves, flower drop, small fruit size, or poor yields year after year.

How to Use Fertiliser for Pomegranates

Spring: Apply CompleteGrow 20-20-20 at bud break for new growth and flowering

FAQs About Good Fertilizer for Pomegranate Plants

What is a good fertilizer for pomegranate plants in pots?

Pomegranate plants in pots need more frequent feeding due to limited soil. A good fertilizer for pomegranate plants like CompleteGrow 20-20-20 is perfect because it’s liquid, balanced, and easily absorbed.

Why are my pomegranate flowers dropping?

This is often due to phosphorus or boron deficiency, or watering stress. Feeding with a good fertilizer for pomegranate plants restores key nutrients to help flowers hold and fruit properly.

Can I use citrus or tomato fertiliser for pomegranates?

Pomegranates need a balanced NPK and specific micronutrients. Citrus or tomato formulas may not supply the correct ratios. For best results, use CompleteGrow 20-20-20, a proven good fertilizer for pomegranate plants across Australian soil types.
