For Preserved Blooms, do not press, bend or squash the petals or stems. They're delicate and can be easily damaged. To clean and upkeep, to prevent your preserved flowers from discolouring, avoid placing them under direct sunlight. Dust them every now and then gently with a tissue or a hairdryer.
Do not keep your preserved flowers in humid places or environments. In coastal or rainy areas where humidity is very high, keep them away from places where air enters or where there are ventilation grilles. Instead, keep them in cool and dry environment.
