Position
Barton pecan trees thrive in areas with hot summers and moderate winters. They do require 800-1000 chill hours below 7 degrees.
They require full sun exposure to produce abundant nuts. Ensure they are planted in a location where they will receive at least 6 to 8 hours of direct sunlight daily.
Dig a hole approximately 1m x 1m and 1m deep, ensuring the tree is planted at the same depth as it was in the nursery black bag.
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 nut trees prefer well-drained soil that is deep and fertile. 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 a bag of acid compost and well-rotted manure before planting can improve soil structure and fertility.
Mulch
Apply organic mulch to your pecan nut tree all year round.
Use from 2 to 5 centimetres of pine bark mulch to protect the roots from UV damage and drying out. It retains moisture, and maintains an optimal pH. Do not let the mulch touch the plant stem, as it may cause infection or rot.
Watering
Young Barton pecan trees need regular watering, especially during dry periods, to help them establish a strong root system. Water them very well and deeply once a week for the first 2 years. Drip irrigation or deep watering works well to promote deep root growth.
Once established, pecan trees are somewhat drought tolerant but will still benefit from supplemental watering during prolonged dry spells. For mature trees, soil moisture determines the yield, size and fullness of nuts and the amount of new growth. Water them often enough to keep the soil evenly moist from when the buds swell until harvest.
Fertilising:
Pecan trees, including Barton, are heavy feeders and require regular fertilization to support their growth and nut production. Apply our slow-release nitrogen-rich all plant fertiliser. Apply 1 teaspoon every 4-5 months. The roots will absorb what they required.
Pruning:
Prune your pecan nut 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.
Pests
The larvae of the Casebearer can damage the nuts. You may need to spray insecticides or use biological controls.
Pecan Scab a fungal disease can affect the leaves and nuts. Fungicide treatments and proper spacing for good air circulation help control it.
