Where and when to plant Super Max onion

Red onion stores longer, while yellow onion yields more. Pick a variety that bulbs in the short days of the Philippine dry season, and plant it after the rains so the bulbs dry well. 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.
