I had several seeds in a sealed zip-lock bag that were accidentally washed with my laundry. The bag does not seem to have opened during the wash. Do you think they are still good to plant?
We’ve seen this happen several times before. From your description, it sounds like your seeds should still be viable. If the bag went through the wash unopened and had no leaks, the seeds shouldn’t have gotten wet.
Try germinating them to see if they grow. They most likely will if they were viable BEFORE they went through the wash. Even with seeds that have not been through a laundry cycle, you usually find that some will NOT germinate. They may have been too old, or the soil isn’t the correct pH, etc.
In the future, if your seeds do accidentally get wet in the laundry (or anywhere else) try germinating them right away. We place our seeds on a wet paper towel on a plate and cover them with another wet paper towel to sit in the dark for 18 to 24 hours to start the germination process.
