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.
Probably one of the least known edible plants is the cattail. Cattails are usually found near the edges of freshwater wetlands. Most of a cattail is edible. You can boil the roots or eat them raw. You can also eat most of the stem of the plant. The best part of the stem is near the bottom where the plant is mainly white. Again, you can either boil or eat the stem raw. You can also boil the leaves and eat them as you would any other greens.
