Reissue patents can be used to correct errors such as failure to perfect claims for priority (e.g., failure to properly claim a priority filing date of an earlier filed foreign or U.S. patent application), defects in the drawings or specification, improper inventorship, and claiming more or less than what was proper to claim in the original patent.
There are a lot of ways you can be frugal in your garden and save some money. The potting mix you use in your container gardens should be something you feel comfortable splurging on. In my opinion, the best potting soil for edible container garden is the Happy Frog line of potting soil distributed by FoxFarm.
Greens may be grown on a variety of soils. Loams will generally produce the greatest yields but for early spring growth and overwintering, sandy loams are best. Soils should be well drained, rich in organic matter and thoroughly tilled. A pH of 6.0 to 6.5 is desirable for all of the greens except spinach, which thrives best in a soil pH 6.5 to 6.8.
