To maintain the beauty of your bouquet of 20 O'Hara roses with beautiful wrapping, follow these care tips:

1. **Watering**: Fill a clean vase with room temperature water and trim the stems of the O'Hara roses at a diagonal angle before placing them in the vase. Change the water every two days to keep it fresh.

2. **Placement**: Display the bouquet in a cool location away from direct sunlight and drafts. O'Hara roses prefer cooler temperatures to prolong their freshness.

3. **Trimming**: Trim the stems of the roses every few days, cutting them at a diagonal angle to allow for better water absorption. Remove any leaves that will be submerged in water to prevent bacterial growth.

4. **Avoiding Ethylene**: Keep the bouquet away from ripening fruits and vegetables, as they release ethylene gas, which can cause the roses to wilt more quickly.

5. **Misting**: Lightly mist the roses with water to keep them hydrated, especially if the air in your home is dry.

6. **Enjoyment**: Take time to appreciate the beauty of your bouquet and remove any spent blooms promptly to encourage new growth.

By following these care tips, you can enjoy your bouquet of O'Hara roses for as long as possible, adding a touch of elegance and fragrance to your space.
