Carnations, chrysanthemums, orchids, and zinnias last longer than dahlias, lilies, roses, and sunflowers. In general, the more delicate the flower, the shorter its life.

Like many cut flowers, they won't last forever, but they will last a good long time. Here are some tips to keep your flowers fresh and make your bouquet last:

1. Cut Two Inches off the Flower Stems Before Placing Them in Water

Garden shears will make the cleanest cut, but regular scissors will also work. To get more water into the stem, cut at a 45-degree angle. The stems of some flowers, like roses, must be cut so that air bubbles don't get stuck in the branches and the water doesn't move.

2. Choose a Vase Appropriate for Your Flower Type

The arrangement of flowers in the vase will have a lot to do with how long your cut flowers last. For example, if you have a lot of open space in your vase, you will have to change the water more often. 

Different types of flowers need to be in various vases, or they will wilt. For example, carnations and orchids need tall, straight vases. In contrast, zinnias, chrysanthemums, and gerbera daisies are better off in vases with holes at the bottom to help the water drain out.

3. Only Use Room Temperature or Warmed Water in Your Vase

Never use cold water. Coldwater can damage the flowers. If your vase is in cold water and you want to warm it up a little, run the vase under warm water.

If you find your flowers are not lasting as long as they used to, try changing the water more often. It would be best to use room temperature or warmed water and store your flowers in a cool, dark place.

4. Change the Water Every Two to Three Days

Different flowers require different amounts of water. Carnations and chrysanthemums can go for three weeks without water, whereas roses will last only four days without water. Your flowers will generally last longer if you change their water every three days. 

If your vase has holes that drain the water, you should change your water every day. However, this may depend on the type of flower you're keeping. For example, orchids will last longer in water than carnations and chrysanthemums.

5. Use Floral Preservatives

Floral preservatives are mainly used for keeping flowers hydrated and healthy, but they can also help you extend the life of your cut flowers. They are not meant to make your flowers last forever, but many floral designers agree that floral preservatives are an excellent investment to keep your flowers looking their best. 

Floral preservatives are relatively inexpensive and are used with the water you store your flowers in. This keeps water from evaporating quickly and makes flowers fresher for longer.

Conclusion

Different flowers last for different amounts of time, but by following the above tips, you can make your bouquet last for a long time. If you want to reuse your flowers, cut them two inches from the bottom and then place them in a vase with fresh water.
