When to fertilize

What to inspect

For container-grown hyacinths, feed from early spring until six weeks after flowering. Bulbs grown in water in glass vases need no feed.

What changes it

Feed potted bulbs during spring flowering and for six weeks afterward, then stop as foliage yellows and the bulb enters storage or rest. Bulbs grown in water need no fertilizer.

Follow the product label

Fertilizer type and dose

Use a high-potassium liquid fertilizer, such as a tomato fertilizer, for bulbs grown in pots and follow the package directions. Use no fertilizer for a bulb grown in a water vase.

Take the dose and frequency from the chosen product label. No universal household milliliter dose is established, and a water-forced bulb needs no fertilizer.

Warning Signs

A wilting display or yellowing foliage should prompt a check of the bulb’s container, water-vase setup, and seasonal stage rather than automatic extra feed. Stop watering as container foliage yellows.
