Growth Stages

Clove Sprouting

2-3 weeks

Individual cloves send up green shoots within 2-3 weeks of planting. Root development occurs below soil surface.

Keep soil consistently moist but not waterlogged. Ensure good drainage to prevent clove rot. Light mulch helps retain moisture.

Vegetative Growth

4-6 weeks

Multiple green shoots emerge from each clove, developing into thin leaf blades. Plants establish root systems and bulbs begin to form underground.

Maintain steady moisture and remove any weeds. Apply balanced fertilizer every 3-4 weeks. Mulch to conserve moisture and suppress weeds.

Bulb Development

6-8 weeks

Clusters of elongated bulbs form underground as the banana-shaped characteristic develops. Foliage continues to expand above ground, reaching 12-18 inches tall.

Reduce nitrogen to encourage bulb development. Continue regular watering but allow soil to dry slightly between waterings. Monitor for pests and disease.

Bulb Maturation

3-4 weeks

Foliage yellows and dies back. Bulbs harden and reddish-bronze skin develops, with flesh becoming more pronounced. Plants slow growth and focus energy on bulb ripening.

Significantly reduce watering as foliage dies back. Stop fertilizing. Avoid excessive moisture to ensure good storage quality.

Harvest Ready

At harvest

Foliage is completely dried and fallen over. Bulbs are firm with papery skin, ready for harvest and long-term storage.

Stop watering entirely. Allow bulbs to cure in the ground for several days after foliage dies if weather permits, or cure indoors after harvest.

Harvest Tips

Harvest when foliage has completely dried and fallen over, typically late June to early July in most zones. Gently dig bulbs and allow them to cure for 2-3 weeks in a warm (70-75°F), dry, well-ventilated area. Once cured, store in a cool (50-60°F), dry location with good air circulation. Properly cured Shallot Banana bulbs can store for 6-8 months.
