Garlic Fertilizer: What and When to Feed Garlic
How to fertilize garlic: preparing the bed with compost, nitrogen in early spring, when to stop feeding, organic options and signs of deficiency.
Garlic is a fairly hungry crop for its size. Prepare the bed with compost or well-rotted manure before planting, then give a nitrogen feed in early spring when growth resumes and again a few weeks later. Stop feeding once bulbs start to swell, usually by late spring.
Feeding Schedule
| Time | What to apply |
|---|---|
| Before planting (autumn) | Compost or aged manure; a little balanced fertilizer |
| Early spring (new growth) | Nitrogen: blood meal, feather meal, fish emulsion or a balanced feed |
| 3–4 weeks later | A second light nitrogen feed |
| From bulb swelling | Stop feeding |
Tips
- Avoid fresh manure, which encourages rot.
- Late nitrogen produces leafy plants and poorly storing bulbs.
- Garlic likes sulfur; most soils supply enough.
- A soil pH of 6–7 is ideal.
Signs of Deficiency
- Pale, yellowing leaves in spring: nitrogen.
- Weak growth on sandy soils: general shortage; add compost.
Yellow leaf tips in early spring can also be frost damage or natural; check the whole plant.
