Gliricidia
Gliricidia sepium
shrubGliricidia is a fast-growing, nitrogen-fixing leguminous shrub native to Central America and Mexico. It is widely cultivated in tropical and subtropical regions as a green manure crop, fodder plant, and living fence. The plant produces small pink or purple flowers and is valued for its ability to improve soil fertility while providing nutritious livestock feed.

Establishment (0-3 months)
3 monthsSeedlings emerge with oval cotyledons and rapidly develop compound leaves; cuttings root and begin new shoot growth
Keep soil consistently moist but not waterlogged; provide light shade for young seedlings; remove weeds around base; stake cuttings if necessary for support
Vegetative Growth (3-9 months)
6 monthsRapid stem elongation with compound pinnate leaves; plant grows tall and woody; develops strong branch structure
Provide support if growing as standalone plant; minimal fertilizer needed due to nitrogen-fixing capability; prune lower branches if using as living fence; thin competing shoots
Flowering (9-18 months and recurring)
Recurring 6-8 week periodsClusters of small pink, purple, or white flowers appear along branches; flowers are fragrant and attract pollinators; flowering occurs multiple times annually in warm climates
Continue regular watering and light feeding; do not prune heavily during heavy flowering; allow flowers to set seed if seed production is desired
Pod Development & Seed Maturation (2-4 weeks after flowering)
3-4 weeksElongated, flattened green seed pods develop; pods mature to brown and may naturally split open to disperse seeds
Collect pods before they split for seed saving; allow some pods to mature on plant for natural reseeding if desired; monitor for pod-feeding insects
Mature Hedge/Fodder Production (18+ months)
Indefinite; perennialPlant reaches mature size with dense foliage suitable for cutting; produces continuous regrowth after harvesting; functions as living fence or continuous biomass source
Harvest leaves and branches for green manure or fodder every 2-4 months; allows coppicing (cutting back to stimulate bushier growth); maintain desired height and shape through regular pruning

Common Pests
-
Hand-pick affected pods; plant trap crops; encourage natural predators; severe infestations may require neem oil spray
-
Strong water spray to dislodge; increase humidity around plant; neem oil or sulfur spray if severe
-
Prune affected branches; horticultural oil spray; encourage natural predators like ladybugs
-
Improve air circulation through pruning; remove affected leaves; avoid overhead watering; apply copper fungicide if severe
Uses
Livestock Fodder
CulinaryGliricidia leaves are highly nutritious forage for cattle, goats, sheep, and poultry, with high protein content (up to 20% dry matter) and excellent palatability. It provides sustainable, low-cost animal feed in tropical regions and improves livestock productivity. [source]
Green Manure & Soil Improvement
HouseholdAs a nitrogen-fixing legume, Gliricidia captures atmospheric nitrogen and enriches soil when incorporated, reducing the need for synthetic fertilizers. Its rapid biomass production makes it an excellent green manure crop for sustainable agriculture. [source]
Living Fencing & Erosion Control
HouseholdGliricidia grows rapidly into dense hedges suitable as windbreaks, property boundaries, and living fences. Its deep root system helps prevent soil erosion on slopes and stabilizes hillsides. [source]
Traditional Medicine
MedicinalIn Central American and tropical cultures, various parts of Gliricidia have been used to treat skin conditions, parasites, and inflammatory diseases. Leaves and bark contain bioactive compounds with antimicrobial properties. [source]
Pollinator Support & Wildlife Habitat
WildlifeThe abundant pink and purple flowers attract bees, butterflies, and other pollinators, supporting biodiversity in agricultural landscapes. The dense foliage provides shelter for beneficial insects and small animals. [source]

Harvest Tips
For green manure: Cut and incorporate entire stems and leaves into soil 4-6 weeks before planting main crop, or leave as mulch. For fodder: Harvest branches and leaves every 2-4 months; cut 30-60 cm above ground to allow coppicing and regrowth. For seeds: Collect dried pods and extract seeds when pods brown; seeds can be stored dry for several months. For living fence: Establish with regular pruning to desired height and maintain through periodic cutting.
Fun Facts
- 🌱 Gliricidia is sometimes called 'Mexican sunburst tree' and is extensively used in agroforestry systems throughout Africa, Asia, and Latin America as a sustainable alternative to chemical fertilizers.
- 🌱 The plant is so nitrogen-efficient that farmers can cut and drop its leaves between crop rows, providing natural fertilizer without additional cost—a practice called 'green manuring'.
- 🌱 In traditional Mexican and Central American cultures, Gliricidia was historically used as a natural pesticide and rodenticide; the roots contain toxic compounds (gliricidin) that can kill rodents, which is why the scientific name may derive from Latin 'glis' (dormouse).
