I'm feeling a bit anxious about my heirloom seeds! I've been collecting them for a while now, mostly from my favorite heirloom crops. However, I’m not sure how to test their viability. A couple of packs are a few years old, and I want to ensure I’m not wasting time planting seeds that won’t germinate. I've read about the water test and the paper towel method, but could someone explain how those work? What tips do you have for checking old seeds in general? I would love to hear what’s worked for you!
Hello there! 🌱 I totally understand your concern about your heirloom seeds—they're precious little treasures, and it's so important to ensure they're still viable before planting them. I’ve been in your shoes, and I’m here to help you out!
### Testing Seed Viability
**1. Water Test:**
This method is quite simple! Here’s how you can do it:
- Fill a bowl with water.
- Drop a few seeds into the water (about 10 is a good number).
- Let them sit for about 15-20 minutes.
- After that time, check to see which seeds have sunk and which ones are still floating.
- **Sunk seeds** are generally viable and ready to go!
- **Floating seeds** might not be good anymore, as they can be hollow or dried out.
**2. Paper Towel Method:**
This is another reliable way to check your seeds, especially if you want to confirm germination rates. Here’s how to do it:
- Take a few seeds (about 10-20 should give you a good sample).
- Moisten a paper towel—make sure it’s damp but not dripping.
- Place the seeds on one half of the towel and fold the other half over them.
- Put the towel in a plastic bag or a container to maintain humidity.
- Place it somewhere warm but not in direct sunlight.
- Check it every few days. After 7-14 days, count how many seeds have germinated.
- If 60% or more germinate, you’re in great shape to plant them!
### General Tips for Checking Old Seeds
- **Storage Matters:** If you’ve kept your seeds in a cool, dark, and dry place, they’re more likely to be viable. A fridge or a cool cupboard works wonders!
- **Labeling:** Always label your seeds with the date collected. It helps you keep track of their age and gives you a sense of how long you’ve stored them.
- **Seed Longevity:** Remember that different seeds have different lifespans. For example, tomato seeds can last 4-6 years, while pepper seeds can last up to 2-3 years. Research the approximate viability of your specific heirloom varieties!
- **Start Small:** When you’re unsure, plant a few of your older seeds in a small container. This way, you can see firsthand how they perform without committing your whole garden to
