Sounds questionable to me. Nitrogen fixation is a process by which bacteria convert Nitrogen from the air into a usable form for the plant. Only certain plants can do this. AFAIK, Hosta are not one of them.

Go ahead and try it and let us know what you think.

Recently, after some big storms, my hosta look like they've been given a shot of color. Aren't they taking nitrogen from the air? (Of course, they're back to normal color the next morning.)

They are probably taking nitrogen from the rain.

Lightning starts the change in nitrogen in the air into a form plants can use. See link below.
My plants look good after a rain cuz they're finally clean. ;-)

Looks like this product uses a form of neem to fix nitro and it may work. I'm concerned, however, when Googling "Potenised" (the patented ingedient) and find all kinds of suspicious snake oil, but maybe that's me.

Hmmm was not aware Neem fixed Nitrogen. Corn gluten meal is also used here in the states for nitrogen release as well as a natural weed controller or herbicide. Both however lack phosphorous and potash along with essential micro nutrients so a simple fertilizer with both macro and micro nutrients might be money better spent for you.

Another element common in rain from T-storms is naturally occuring Hydrogen Peroxide. This element is known within the horticultural field to act as a strong catalyst as an uptake module for both macro and micro nutrients and is commonly used in hydroponics. It is in part why you may notice a particular vibrancy to your plants after an intense and powerful thunderstorm. Don't use store bought HP as it contains preservatives, fillers and other man made chemicals. Natural HP can be purchased at any health food store.

Hydrogen Peroxide is a good chemical to use for controlling or eliminating diseases in container plants, but it doesn't have much effect on plant growth. Here's a quote from a USDA research report:

"The results indicate that watering nasturtiums at the tested hydrogen peroxide applications rates did provide slight growth and flowering benefits to nasturtiums grown in containers, although the results were not as great as anecdotal reports would suggest. The most likely explanation for the anecdotal reports of dramatic growth stimulus of hydrogen peroxide watering solutions may be a result of hydrogen peroxide decreasing or eliminating diseases in the soil containers rather than it serving as a direct stimulus to the plant."

"Hmmm was not aware Neem fixed Nitrogen."

Me either...lol...until recently.

Evidently neem (usually neem cakes) as a soil amendment helps slow the nitrification (changing from ammonia to nitrite) of nitrogen. Nitrites (and nitrates) tend to leach away faster and this keeps the nitro around longer which, in turn, will increase efficiency of nitrogen fertilizer.
