Whether you’re looking to make your own pesto, sprinkle them on salads, or use them in savory dishes, growing your own pine nut tree can save you money while providing a sustainable and rewarding harvest.
Position
Pine nut trees thrive in hot, dry summers and cool, wet winters. They need full sun and are tolerant of a variety of conditions, including salt, high winds, and stony ground.
Prepare Soil
Garden: Pine nut trees prefer well-draining soil, but they do not tolerate lime. They grow best in stony or gravelly soil.
Pots: Use a large container with good drainage and a well-draining soil mix. Choose a pot that provides enough space for the tree to grow over the next few years.
Feed
Garden: Use a slow-release fertiliser in the spring to encourage healthy growth. Avoid fertilising too much, as pine nut trees do not require excessive feeding.
Pots: Feed with a balanced liquid fertiliser every 6-8 weeks during the growing season.
Watering & Mulching
Water the tree regularly, especially in its early years. Pine nut trees can handle drought conditions once established, but they will need occasional watering during hot, dry spells. Mulching around the base helps retain moisture and prevent weed growth.
Protection
Pine nut trees are hardy and can withstand temperatures as low as -22°C. However, protect young trees from extreme cold or frost while they’re still small. Once established, they are quite resilient.
Harvest
Pine cones take two full seasons to mature. Once the cones turn brown in autumn, dry them in the sun until they open. Remove the seeds by hand, crack the shells, and collect the kernels. The tree will produce 5-15kg of pine nuts per season once it matures.
Pruning
Prune to maintain the shape of the tree, but avoid removing more than 50%-60% of the foliage. Healthy branches are essential for producing pine nuts, and the tree will not re-sprout from bare wood.
Garden Expert Tip
Although pine nut trees can take up to 8 years before they begin producing nuts, they are a beautiful addition to any garden. If you’re in no rush for pine nuts, consider leaving the tree in a pot and using it as a unique Christmas tree.
