Does baby oil preserve flowers?

Baby oil is sometimes suggested as a quick fix for making flowers look glossy, but it is not a preservative. It sits on the surface of the petals rather than replacing moisture inside the cells. The flower will continue to lose water and eventually shrivel or rot, depending on the conditions. The oil can also trap dust and make the flower feel unpleasant to touch.

If you want a shiny finish for a display that will only last a few hours, you can brush a tiny amount of oil onto the petals just before the event. But for keeping flowers long term, avoid it. Better home methods include air drying, pressing, or using silica gel crystals, which you can buy from craft shops. Silica gel draws out moisture quickly and keeps shape and colour far better than oil.

For a fresh bouquet you want to keep for a week or two, the best approach is proper flower food in the water, clean stems cut at an angle, and a cool spot away from fruit and direct heat. Baby oil has no place in that routine.
