How to Fertilize Pomegranate
When Should I Start Feeding My Pomegranate?
Pomegranates leaf out after the last frost, so begin feeding when you see the first new green growth in spring, adjusting for your region's climate.
How Often Should I Fertilize My Pomegranate?
Feed every 4 to 6 weeks from early spring through late summer. That typically works out to three or four applications per season, which is plenty for this relatively undemanding tree.
Young trees (under 3 years) benefit from lighter, more frequent feeding to establish a strong root system. Use half the recommended amount every 3 to 4 weeks instead.
Stop feeding by early fall. Pomegranates are cold-hardy to zone 7a, but late-season nitrogen produces tender new growth that is vulnerable to frost damage. Let the tree wind down naturally before winter.
What Is the Best Fertilizer for Pomegranate?
Start the season with a balanced granular fertilizer like 10-10-10 to support new leaf and shoot growth in spring. Once flower buds appear, switch to a formula with higher potassium (the third number in NPK), such as a 4-8-12 or tomato-type fertilizer. Potassium drives fruit development and sweetness.
Granular, slow-release fertilizers work well for in-ground Pomegranates because they feed steadily between applications. For container-grown plants, liquid fertilizer gives you more control over the dose.
Avoid high-nitrogen fertilizers during fruiting. Excess nitrogen pushes vegetative growth at the expense of flowers and fruit set, and can cause fruit to crack.
