Asparagus can grow up to 10 inches in just 24 hours if the weather is warm! Bull kelp is also a fast-growing seaweed that can grow up to 2 feet per day!
I only have two perennials that are kept in raised beds. Asparagus and strawberries, both are a fight to keep going and i believe it has to do with winter kill. Both are going away this year!
It’s hard to beat fresh from your garden Asparagus; im just to lazy to start over!
Out of Seldovia (across from Homer) there’s a kelp bed that ADFG allows residents to harvest from. Being in the area with the right tide once we decided to load up the back of the boat and bring it home for the garden. It was roughly 10 inches deep in the 6x7ft cockpit and when we got home i layered it on some of the beds. Im sure there was some benefit but it was a lot of work and didn’t break down as fast as i would have liked.
Kelp is a big part of my amendment schedule each year but nowadays i buy 25 lb bags of dry/ground kelp which is more user friendly.
