Growth Stages

1

Establishment

Year 1

Young tree focuses on root development with modest above-ground growth

Water regularly to establish roots. Provide support stake if needed. Remove any competing growth.

2

Vegetative Growth

Years 2-3

Tree develops main scaffold branches and foliage canopy

Prune to establish open, vase-like form with 3-4 main branches. Remove crossing or diseased wood. Apply balanced fertilizer in spring.

3

Breba Crop

April-June

Large figs develop on previous year's wood in late spring/early summer

These are the first crop; handle gently. LSU Purple produces reliable breba crop. Ensure adequate watering.

4

Main Crop Development

July-October

New figs form on current season's shoots in summer and develop through fall

Continue regular watering. Avoid over-fertilizing which promotes excessive foliage at expense of fruit. Monitor for pests.

5

Dormancy & Hardening

November-March

Tree drops leaves in fall and enters winter rest period

Reduce watering. In zone 7, mulch heavily around base (8-12 inches). Consider wrapping trunk and lower branches with burlap in harsh winters. Remove mulch in spring.

Harvest Tips

Figs are ripe when fully colored (dark purple), soft to gentle touch, and slightly drooping on the stem. Harvest in morning when skin has warmed slightly. Twist gently or cut with short stem. Peak harvest is August-October for main crop; June-July for breba crop. Ripe figs do not ripen further after picking, so harvest at full maturity.

Fun Facts

  • 🌱 LSU Purple was specifically bred by Louisiana State University for cold hardiness, making it one of the hardiest fig varieties available and suitable for zones where other figs struggle.
  • 🌱 Figs are technically not fruits but inverted flowers—the edible part is a hollow receptacle containing hundreds of tiny flowers inside, which is why fig seeds are so numerous.
  • 🌱 Fig trees have been cultivated for over 11,000 years, making them one of humanity's oldest cultivated plants, predating agriculture itself in some regions.
