Where and when to plant Purple Duke eggplant

Buyers in each market want their own talong: long and slim and dark purple in most of Luzon, rounder or striped in some towns. Pick a variety with bacterial wilt resistance, and plan for the fruit and shoot borer whatever you plant, because no variety on the market resists it. Before planting, get the field ready with our guide: Pagtatanim ng gulay.

Before you buy seed

  • Buy sealed packs or tagged sacks from an accredited dealer, and check the packing date and germination rate.
  • Ask your municipal agriculturist or nearby farmers how it did in your area last season.
  • Try it on a small area first, beside the variety you usually plant, before you switch 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.
