If I buy seeds now, will they be good for next year’s garden?
Answer: Yes—if stored properly, most seeds will remain viable for at least a year, and many last even longer.
How Long Will Seeds Last?
While it varies by crop, here’s a quick guide for average seed longevity under good conditions:
- 1–2 Years: Onion, parsley, sweet corn, chives, basil, dill
- 3–4 Years: Carrots, lettuce, spinach, peas, beans, kale
- 5+ Years: Tomatoes, squash, cucumbers, melons, watermelon
How to Store Seeds for Next Year’s Garden
Seeds are living organisms, and how you store them can make a big difference in how well they germinate later. To keep seeds in good shape until next season:
- Keep Them Cool: A consistent temperature between 32–41°F is best. The fridge works well—just avoid extreme heat or freezing without proper drying.
- Keep Them Dry: Moisture is the #1 seed killer. Store seeds in airtight containers (like jars or sealed bags), and add a desiccant like rice or silica gel. Never vacuum seal seeds.
- Keep Them Dark: Light can trigger premature aging. Use opaque containers or store in a dark cabinet or refrigerator drawer.
Pro Tip: Test Old Seeds
Before planting older seeds, test them: place 10 seeds in a damp paper towel, roll it up, and keep it warm. After 7–10 days, see how many sprout. A germination rate of 70% or higher is usually fine.
Bottom Line
Yes—buying seeds now is a smart investment for next season. Just store them cool, dry, and dark, and you’ll be ready to plant your garden when spring rolls around.

FAQ: Buying Seeds Now for Next Year
Will seeds I buy now still be good for next year?
Yes, as long as you store them properly, most seeds will stay viable for at least a year, and many will last even longer. Buying early is a smart way to prepare for next season.
How long do seeds usually last?
Seed lifespan varies by variety. Some, like onions, parsley, sweet corn, and basil, usually last 1 to 2 years. Others, like carrots, lettuce, peas, and beans, often remain viable for 3 to 4 years. Long-lasting seeds such as tomatoes, cucumbers, and melons can stay good for 5 years or more under ideal conditions.
What’s the best way to store leftover seeds?
The key to storing seeds well is keeping them cool, dry, and dark. A refrigerator drawer works well if the seeds are in airtight containers. Avoid moisture, heat, and light to prevent premature aging or decay.
Can I store seeds in the freezer?
Freezing is only safe if the seeds are fully dried beforehand. Otherwise, ice crystals can form inside and damage them. Unless you’re experienced with drying, refrigeration is safer and more reliable.
Do I need special containers for seed storage?
No, you don’t need anything fancy. Mason jars, zipper bags, and sealed tins work well, especially when paired with a desiccant like silica gel or rice to absorb any moisture.
Should I include something to keep them dry?
Yes—moisture is the number one cause of seed failure in storage. Including silica gel packets or uncooked rice can help keep the container dry and protect the seeds.
Is light really a problem for stored seeds?
Yes, light can accelerate the breakdown of seed viability. It’s best to use opaque containers or store seeds in a dark place to keep them dormant until you’re ready to plant.
How can I test old seeds before planting?
You can do a simple germination test. Just place 10 seeds on a damp paper towel, roll it up, and keep it in a warm spot. After 7 to 10 days, check how many sprouted. If 7 or more germinate, your seeds are still good to plant.
Why do some seeds go bad faster than others?
Different seeds have different internal structures. Seeds with higher oil content or thinner seed coats, like corn or onion, tend to lose viability more quickly than hardier types like beans or squash.
Is it a good idea to buy seeds early?
Yes—purchasing seeds now ensures better availability and gives you time to store them properly. As long as you keep them cool, dry, and dark, you’ll be ready to plant a healthy, productive garden next season.
