Where and when to plant Dalandan citrus

Sweet oranges and mandarins grow best in the cooler, drier parts of the country. Buy budded trees on a tested rootstock from an accredited nursery, and keep out greening disease. 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: Land preparation for fruit trees.

Before you buy planting material

  • Buy grafted or budded plants from an accredited nursery, with the variety name on the tag.
  • Ask your municipal agriculturist or nearby farmers how it did in your area last season.
  • Plant a few trees first if the variety is new to your area, before you fill the whole farm.
  • Write down the planting day, inputs and harvest, so you can compare varieties on your own ground. anee.io keeps these records for you.
