How can you keep a four leaf clover?

I have four leafed clovers in a fish tank doing very well

You could laminate it maybe?

The first thing to do is take a wonderful picture of it, just in case. It’s not the best backup, but at least it’s still beautiful.

I would press it using clamps and flower pressing paper (tissue and absorbent paper… it’s been awhile since I did this). That should take out the moisture. Then you’d have to stabilize it… laminating may destroy the dry flower, or may not, I’m not sure. Personally I would display it in a shadowbox that was decorated festively to accentuate the four leaf clover (painted green with clovers around perhaps). The shadowbox would be sealed thus protecting the clover. I’m not sure how this would fare long term wise, as long as it was out of the sun I figure it would last a decent amount of time, decades.

You could:
laminate it
press it
frame it
tape it

try all of those ideas FIRST with other clovers to make sure it’ll turn out okay :)

I had about 30 that I dried and then laminated (do not laminate without drying first, it becomes a wet, green mess).

The old fashioned way was to press them between two sheets of wax paper and iron on low. This way the wax was absorbed by the leaves.

But modern technology has so much more to offer. If you want a way to display it which is also practical for everyday use you could make it into a paperweight. Any good craft store like Michaels or AC Moore has these kits which has everything necessary.

Basically the clover is encased in a clear liquid plastic which hardens and keeps it protected and preserved. I think the main advantage over other methods is that the color is preserved better than with either glycerin or drying in silica.

However, those are two other methods also available if you don’t mind some color difference

The cheapest would be to encase it between two pieces of clear packing tape after thoroughly drying of course.

If it were me I would opt for the paperweight kit.

@TROLL thank you lol I am naturally a clutz soo I think it’s wise to try on something not so important but similar first.

You’ve actually started on the right step I’d say. If your goal is to preserve the actual clover, you’ll want to press and dry it, and then laminate it or otherwise store it in a dry protected location.
Personally, I think it would be awesome to breed four leaf clovers (it’s technically possible), but I have no idea how you would do that in the first place with complete living plant, let alone only part of one that you’ve picked.
