Position
Like other pecan trees, the Ukulinga requires a sunny location (at least 6 to 8 hours of direct sunlight daily) and well-drained soil.
Pecan trees thrives in areas with long, hot summers and adequate rainfall, with a long growing season.
They prefer sufficient winter chilling hours (around 800 to 1000 hours below 7°C).
Size
Pecan nut trees can grow to a height of between 20 – 40m tall. Ensure they are planted at least 10 metres apart and away from structures and power lines.
Soil type
Pecan trees prefer well-drained, deep, and fertile soil. They can tolerate a range of soil types but do best in loamy soils with a pH between 6.0 and 7.0.
Soil should be rich in organic matter. Adding compost or well-rotted manure before planting can improve soil structure and fertility.
Mulch
Mulching around your tree makes it appealing and allows the soil to benefit from a constant supply of nutrients gathered by its slow decomposition process. Mulching will also keep the soil moist on warmer days.
Watering
Young pecan trees need regular watering, especially during dry periods, to help them establish a strong root system. Provide about 1 inch of water per week during the growing season.
Once established, pecan trees are somewhat drought-tolerant but will still benefit from supplemental watering during prolonged dry spells.
Fertilising:
Pecan trees are heavy feeders and require regular fertilisation to support their growth and nut production. Apply our slow-release nitrogen-rich all plant fertiliser. Apply 1-2 teaspoon every 4-5 months. The roots will absorb what they require.
Pruning:
Prune your pecan trees annually during the dormant season (winter) to remove dead, damaged, or crossing branches. This helps improve air circulation and light penetration within the canopy, reducing disease and improving nut production.
Pest and Disease Management:
Aphids, citrus psylla, red scale, citrus greening. Spraying regularly with Agricultural Neem Oil or Effective Microorganisms (EM Control) will assist in either prevention or after the fact. If you already have aphids or mites, wash the tree with a harsh hosing, and when dry, spray with Neem oil or EM Control.
Practice good garden hygiene (remove fallen fruit and leaves).
Watch for root rot (caused by overwatering) and fungal infections during wet periods.
Harvesting
The pecan life cycle begins in October. The trees produce both male and female flowers for pollination.
Pecan trees require pollination by another cultivar as the male and female flowers are not ready at the same time. It is advisable to plant various cultivars of pecan trees to facilitate cross-pollination and optimize pollination.
From March to April the Pecan nut’s shell starts to harden while it is still inside the protective outer shuck (the green outer layer that we can see).
From April, the shuck hardens and dries out, exposing the pecan nut inside.
