Where and when to plant Duku lanzones
Paete and Camiguin lanzones are prized for sweet, seedless segments. Plant grafted trees, which bear years sooner than seedlings. A registered tree variety is a selection from one proven mother tree, and only grafted, budded or marcotted plants carry its traits. A seedling grown from its seed can turn out quite different. So buy from a nursery accredited by the Bureau of Plant Industry, and ask which mother tree the scions came from. Before planting, get the field ready with our guide: Pagtatanim ng puno.
Before you buy planting material
- Buy grafted or budded plants from an accredited nursery, with the variety name on the tag.
