Those old seed packets are so neat. Why don't you try soaking your seeds for a day before planting them? I think it helps when they are really old---almost like reconstituting. Also, wait a bit longer on the beans. They may be taking longer, too.
Well, now is the time to try it, and know how much money you saved then. If you don't sow them, however, it is no savings at all. I keep telling myself this due to the large tote of seeds I had to sort out at the beginning of the season, as I was in the habit of buying seeds, and just putting them away.
Something always seemed to get in the way of my sowing them...work, health reasons and operations. Now, I am at home and my health is better, well, with the exception of sore shoulders and back from digging and sifting out roots from the soil. I hope that I will be able to continue my garden plans, as I am not getting any younger (68)! I know that many continue to do so in to their 90's, but I doubt I will be able then.
I always buy more seeds than I have room for. I have already started many types this season, most are already out. Then there are those types you try and don't do well in the area...I keep the seeds but will probably never grow them again. I like to try new things, though.
Sometimes it is not the seeds but the year. At times some years are better than others for certain varieties, so that might give you a reason to try them again.
Do you have a large tote of seeds like I do? Or do you have a place to put them so you can get at them easily? I had a large tote, then broke them down into categories of types, then start dates, as I knew little about these before. Then I put the different groups into smaller boxes accordingly.
No, sometimes certain plants don't so well in my location...like I LOVE California poppies, and try them every year, but rarely get one to live long enough to flower. I keep my seeds in a plastic tote, which I periodically go through and clean out. I used to keep my seeds in the refrigerator, I do think they keep longer that way...but I have too many now.
