Does granular fertilizer replace liquid fertilizer in the vegetable garden?

They're complementary: granular fertilizer provides a long-lasting base and liquid fertilizer allows quick adjustments during the cycle.

Fertilizers for Vegetable Gardens and Fruit Trees: Which Feed to Use at Each Growth Stage

Q: Can I use the fruit-swelling fertilizer from the start of the growing cycle?

It's not ideal; in the early stages an overall balance is best, saving the fruit-swelling fertilizer for the final stage before harvest.

Quick answer: a vegetable garden needs a different fertilizer depending on the stage: a balanced base feed during growth, an extra boost during the fruit-swelling stage, and specific formulas for demanding crops like citrus. Fertinagro Vida covers this in both liquid form (fast action) and granular form (longer-lasting base feed), with conventional and certified BIO organic versions.

Liquid fertilizers for the vegetable garden

Product	When to use it	Highlight
BIO Liquid Vegetable Garden and Fruit Tree Fertilizer	Throughout the entire growing cycle	Highly balanced, suitable for organic farming
BIO Special Fruit-Swelling Fertilizer	Final stage before harvest	Boosts fruit swelling and improves the quality of fruits and vegetables
BIO Aromatic and Medicinal Plant Fertilizer	Basil, mint, rosemary and similar herbs	Enhances aroma without forcing excessive growth

Specific for citrus trees

BIO Citrus Fertilizer: organic granular fertilizer specially designed for swelling lemons and oranges.
Technological Citrus Fertilizer: high-nitrogen NPK, not organic, for a more intense fruiting action.

Granular base fertilizer

BIO Granular Vegetable Garden and Fruit Tree Fertilizer (with rock phosphate) is the base feed for the whole season: it's worked into the soil at the start of the crop and releases nutrients more gradually than a liquid, available in 800 g and 4 kg tubs.

How to combine them in an organic vegetable garden

When preparing the bed: work in the BIO Granular Vegetable Garden and Fruit Tree Fertilizer as a base feed.
During growth: water with BIO Liquid Vegetable Garden and Fruit Tree Fertilizer every 1-2 weeks as indicated on the label.
In the final stage, before harvesting: switch to the BIO Special Fruit-Swelling Fertilizer to maximize size and flavor.
If you grow citrus in pots or in the garden: use the specific citrus line instead of the general vegetable garden fertilizer.

Frequently asked questions

Can I use the fruit-swelling fertilizer from the start of the growing cycle?

It's not ideal: in the early stages the plant needs more overall balance to develop roots and foliage; the fruit-swelling fertilizer works best concentrated in the final stage, close to harvest.

What's the difference between the BIO citrus fertilizer and the technological one?

The BIO one is organic and suitable for certified organic farming; the technological one is conventional, with higher nitrogen content, for a more intense fruiting action where organic certification isn't required.

Does granular fertilizer replace liquid fertilizer?

They're complementary: granular fertilizer provides a long-lasting nutritional base and liquid fertilizer allows quick adjustments during the growing cycle.
