How do you grow naartjie trees?

To grow naartjie trees, choose a sunny location with well-draining soil, ideally slightly acidic to neutral. Plant the seeds or young saplings in spring after the last frost, ensuring they receive regular watering without becoming waterlogged. Fertilize with a balanced citrus fertilizer during the growing season and prune the tree to encourage healthy growth and fruit production. Protect the tree from pests and diseases for optimal development.
