can you preserve fresh flowers in resin? (the truth about moisture)

If you’ve ever seen a stunning, crystal-clear resin block filled with vibrant wedding flowers, you might wonder how those blooms got in there. Can you just drop a freshly picked flower straight into liquid resin?

The short answer is no. While it sounds simple, putting fresh flowers into resin is a recipe for disaster.

Here is why every flower must be completely dry before it goes anywhere near resin!

 

The Problem With Moisture: Why Fresh Flowers Don't Work

Resin and water are absolute enemies. Fresh flowers contain a high amount of natural moisture and sap. If a fresh or even slightly damp flower is sealed inside liquid resin, a few terrible things happen:

Cloudy Resin: Moisture reacts with the curing resin, turning the crystal-clear block milky, hazy, or cloudy so you can't even see through it.

Browning and Greying: Instead of looking fresh and colourful, wet petals trapped inside resin quickly bruise, turn dull grey or brown, and lose all their vibrancy.

Mould and Rot: Because resin creates an airtight seal, any trapped moisture has nowhere to go. Over time, the trapped water causes the flower to rot and grow mould inside your solid keepsake.

 

How Professional Preservation Works

To prevent this from happening, professional preservation requires a careful drying process. Flowers must be completely dehydrated, often using specialised drying mediums like silica gel over several weeks, to strip out every single drop of moisture while locking in their shape and colour.

Only once a flower is 100% bone dry is it safe to be cast in layers of crystal-clear resin.

 

What This Means for Your Keepsake

If you are thinking about trying a DIY resin project at home with fresh flowers from a bouquet, it is vital to dry them first! Skipping this step means your gorgeous flowers will sadly spoil inside the resin.

If you'd rather leave the complex drying and casting process to an expert to ensure your wedding flowers turn out flawless, make sure they are properly dried - or send them fresh to a professional right after your big day so they can be dried correctly in the studio!
