How to Dry Flowers for Potpourri and Botanical Crafts
Updated: Oct 18
Choose a drying method for the finished project: loose fragrant petals for potpourri, flat flowers for cards, or shaped flower heads for an arrangement. A flower that keeps its colour does not necessarily keep a strong scent.
What to pick and when
Lavender, rose petals and chamomile are useful for fragrant projects. Strawflowers and many seedheads offer texture for decorative work. Identify the plant and intended use before picking; decorative flowers are not automatically suitable for heating or drinking.
Pick on a dry day after dew has evaporated. Choose healthy material without mould or insects and use clean scissors. The ideal stage varies by plant; avoid relying on a single rule such as harvesting every species just after opening. Remove damaged parts and dry promptly.
1. Air drying: bunches and loose petals
Remove excess leaves and make small loose bunches of suitable stems.
Hang in a dry, ventilated place out of direct sunlight, leaving space between bunches.
Spread loose petals or flower heads in one layer on a clean mesh screen or absorbent paper. Turn gently and replace damp paper.
Check the thickest parts before storage. Drying time depends on the plant, humidity and airflow; a calendar alone cannot confirm dryness.
2. Pressing: for cards and framed work
Lay thin flowers or individual petals between clean absorbent sheets in a flower press or protected book. Keep them separate and replace damp sheets. Thick blooms may need separating into petals. Pressing makes flat craft material, not a three-dimensional bouquet.
3. Silica gel: preserving decorative flower shapes
Use flower-drying silica gel and follow its manufacturer’s instructions for the plant, container, drying time and handling. It can help support delicate shapes. Keep treated flowers labelled for decorative use only; do not move them into tea or simmer pot recipes.
What about an oven or air fryer?
Heat can brown delicate petals or reduce fragrance. Air circulation can also lift loose material towards a heating element. Use an appliance only if its instructions allow the particular material and arrangement. Do not prop an oven door open against its instructions. For delicate flowers, start with air drying or pressing.
Storage and uses
Let material cool if relevant and check it is dry throughout before putting it into a clean airtight container. Label the plant, date and drying treatment. Store cool and dark, checking for condensation or mustiness. Discard mouldy material. Colour and scent will change over time.
Keep craft flowers separate from ingredients intended for heating or food. Do not spray fragrance botanicals with hairspray and later heat them. For tea, use correctly identified edible flowers grown and handled for food use; this drying guide is not a food-preservation method.
