I'm impressed with how many beans I can get with pole bean plants. I have a total of 15 pints canned so far and probably will have twice or more than that by the end of the season. I think I planted a dozen but I don't remember. The trellis (12 foot wide by 8 foot tall) is covered all over with them. I bought a Presto 23qt pressure canner for $75. The first batch I did only 5 pints. The 2nd batch 10 pints and that was only half the amount the canner can do. I do have a question concerning the results. I think I packed the jars as tight as possible. The beans were filled to the bottom of the part the rim screws onto. And I filled to the same point with clean boiling water. But after the canner process the water level in the jars was lower as seen in the pics. Did I do something wrong or is that completely normal? In my 2nd batch a few jars had slightly higher water levels than the rest. But most of them are like those in this first batch. Click/tap on the pics as they are larger than they appear in the post.
