step-by-step: how to properly dry flowers

Your wedding day flies by in the blink of an eye, but your bouquet doesn't have to fade away with it. Turning your wedding flowers into a resin keepsake (whether it’s a statement block, an anniversary frame, or a ring holder) is one of the most magical ways to freeze a core memory in time.

However, before your flowers can be safely cast into crystal-clear resin, they have to go through the most crucial step of all: drying.

If you're wondering how to dry your wedding flowers at home or want to know the secrets behind professional preparation, this guide covers everything you need to know to get your petals ready for preservation.

 

Why Proper Drying is Non-Negotiable

It’s completely natural to be excited to see your finished resin piece, but flower drying is a labour of love that cannot be rushed.

Preventing Mould: If flowers retain even a tiny bit of moisture before hitting the resin, trapped water will cause them to rot, decay, and turn mouldy from the inside out.

Protecting the Resin: Trapped moisture can also react poorly with liquid resin, causing it to "flash cure," overheat, and scorch your delicate petals.

Taking your time here ensures your keepsake pieces lasts a lifetime.

 

Air-Drying (Simple & Stress-Free)

If you're planning to use your petals for flat or smaller resin pieces like date frames, keyrings, or tree decorations, natural air-drying is a wonderfully simple approach. 

Set up your space: Find a well-ventilated room out of direct sunlight.

Lay them out: Place your petals and smaller flowers flat on scraps of paper, leaving plenty of breathing room between each petal. There is no need to press them under heavy weights - just let them breathe naturally.

Deconstruct larger flowers: If any flowers are larger than a 50p coin, gently take them apart petal by petal before drying. Smaller flowers can usually stay whole.

Less is more: You won't need to dry your entire bouquet. Saving three or four of each stem type is usually more than enough to create a stunning layout.

The wait: Depending on the flower variety, air-drying takes about two to three weeks. You’ll know they are ready when they feel light, crisp, and no longer stick to the paper.

Tip: Not quite sure if your DIY-dried petals are ready? You can always send a photo and check with a professional preservation artist before casting!

 

Silica Sand (For 3D Block Preservation)

If you are dreaming of a thick, three-dimensional resin block that keeps your bouquet looking completely round and lifelike, air-drying won't quite cut it.

The technique: Silica sand is a fine, porous crystal medium that absorbs moisture rapidly while physically supporting every single petal.

Why it works: Flowers buried gently in silica sand hold onto much more of their original shape, 3D depth, and intricate structural detail compared to flat drying.

The timeline: Whole flowers submerged in silica typically need anywhere from 2 to 4 weeks (sometimes up to 6 weeks depending on density) to completely dry out before they are safe to cast.

 

Professional Preservation vs. DIY

While drying flowers at home is a fun and rewarding DIY project for smaller crafts, larger structural pieces and high-end wedding blocks require specialised equipment, climate control, and precise layering techniques.

If you'd rather skip the stress of handling your precious wedding day flowers, sending your bouquet off to a professional ensures every stem is handled with expert care, from the initial moisture-removal phase right down to the final crystal-clear pour.
