To keep seed from spoilingâ¦. 1  Store birdseed properly in airtight containers in a cool, dry place out of reach of rodents. 2  Avoid buying more birdseed than can be used in a few weeks. 3  Only fill feeders with enough seed for 2-3 days so it won't spoil in open feeders or poor weather.
Because they are sensitive to drying, recalcitrant seeds must be stored at 92 to 98% RH. The best storage temperature depends on the chilling sensitivity of the species. Seeds from many tropical fruits (mango, avocado, cocoa, jackfruit) are sensitive to ch illing and should be stored at â¥15 Â°C (59 Â°F).These seeds have the shortest potential shelf-life, remaining viable for 2 weeks to 3 mo.ecalcitrant seeds. Intermediate seeds are produced by perennials of tropical and subtropical origin (such as coffee, citrus, macadamia, and papaya) and by some tree nut species (for example, walnut, hickory, pecan, hazelnut, and pistachio).
