Calla lilies (also known as Arum lilies) last well in a vase, sometimes up to two or three weeks under the right conditions. Callas are beautiful flowers, perfect for adding some natural brightness to a room or for adding a special touch to a wedding bouquet. However, as with most flowers, calla lilies require some special pampering to bring out their best looks. To ensure that your cut calla lilies stay fresh, you can prep them, ensure their ongoing health, and take additional measures if they are being used in a wedding bouquet.

Prepping Cut Lilies

  1. If you are cutting calla lilies yourself, give the plant a good watering the night before. This will ensure that they will be hydrated when you cut them.
    • Hydrated flowers will last much longer than ones that are cut when they are dehydrated. [1]
    • Cut the flowers early in the morning before the day heats up to prevent them from drying early.
    • Use a clean sharp knife to remove flowers at the base of the stem.
  2. If you have purchased or been gifted callas, unwrap them as soon as possible. Immediately after unwrapping, get them into water quickly. [2]
    • If you are unable to do this, put them in a cool, dimly-lit place such as a basement until you can attend to them.
    • Make sure that they remain cool so they do not wilt.

  3. Calla lilies are very fragile flowers. The less you can handle them, the better. [3]
    • Especially avoid handling the flower heads.
    • If these have been supplied with a protective wrapping, carefully remove it.
  4. You’ll need a deep vase for tall callas. Use a very clean vase; some florists clean vases using a combination of dish soap and a little bleach.
    • Rinse very carefully afterwards to remove cleaning product residue.
    • Any remaining product residue can kill your flowers quickly because it is toxic.
  5. Measure your calla lilies against your selected vase to determine where best to cut them. Cut them to make sure that they can protrude from the top of the vase while at the same time making sure their stems will remain in the water.
    • Use a sharp clean knife to cut the stem at a 45 degree angle.
    • Cutting the stems at an angle maximizes the amount of cut cell in contact with the vase water, which will help the plant take up more water.
    • Cut them underwater so the cut surface isn’t exposed to the air.
    • Avoid using a dull knife, or a pair of scissors, as these tend to crush as they cut.
    • This cell damage stops the plant from being able to absorb water.
    • Lilies won’t appreciate being crowded in a vase so avoid putting too many into one container.
  6. Add flower feed to the vase water or, if you have none, a teaspoon of sugar and a drop or two of bleach for every two liters of water.
    • Some people advise using a dash of Sprite or 7-up instead.
    • Regular calla lilies will need a vase filled about 2/3 full of water.
    • Mini callas will want much less than this, as only the lower part of the stem should stand in the water.
    • This prevents the stem from going soggy on a mini calla.

Ensuring Ongoing Health

  1. Callas will do best in a cool room that isn’t too light and is away from direct sunlight or other sources of heat, like radiators. [4]
    • Avoid putting them near a TV or computer, as these areas can get warm with extended use.
    • Keep them out of drafts.
    • Keep them away from fruit bowls, as ripening fruit emits gases that will encourage the flower to mature, shortening its lifespan in the vase.
  2. Aim to replace the water every day or two and keep it topped up. A steady supply of water is essential to the health of your lilies, and should never be neglected.
    • Mini callas will probably need additional water more often as they should be sitting in less water than regular ones.
  3. Some people like to keep their vase in the fridge overnight to preserve the life of their flowers – but be warned you need a big fridge for this!
    • It’s a bad idea to expose calla lilies to a gas called ethylene, which is produced by some foods, so only store your lilies in an empty fridge.
    • It’s probably best not to put them in a domestic fridge.
  4. The water in your vase will need a complete changing every day or two. This is to prevent any bacteria in the water from building up and attacking your lilies.
    • It also stops the water from smelling.
    • Callas will absorb a lot of water, so keep it topped up.
  5. Every second or third day, trim another half inch off the bottom of the stems. This is because the cells at the end of the stem will die.
    • Refreshing the cut helps exposes fresh cells and helps them absorb water.
    • Replace the water in your vase when you do this.
    • Remember to replace the flower feed or whatever additive you were putting into the water.

Cutting Lilies for Flower Bouquets

  1. If you are using calla lilies as part of a wedding bouquet, let them sit in a vase in a cool place until 30 minutes before you need them. Remove them from the water 30 minutes before using them to avoid water dripping onto clothing.
    • It may be a good idea to dip the cut ends in melted wax to help seal them.
    • Alternately, try putting a cotton ball at the end of the stem and wrapping it with cloth underneath ribbon.
    • This will help seal the end to stop it brushing against clothing and leaving a stain.
  2. Calla lily pollen will stain clothing. You can remove the ‘spadix’ – that’s the yellow finger-shaped thing inside the flowerhead [5] – but this ruins the appearance of the flower.
    • The best option to avoid staining is to just be careful when you are handling the flowers.
  3. If your callas are being transported some distance to their final destination, after arrival they need to ‘condition’ in a cool dark room for about 6 hours before you arrange them in a bouquet. [6]
    • Cut the ends and let them sit in a bucket of lukewarm water in a cool dark place such as a basement
    • This helps them rehydrate after transport to preserve their lifespan and look their best.
    • If any are still looking limp after this time, recut the ends and repeat the conditioning.
    • If any pollen is visible on the flower petal, avoid using the flower.
    • This is a sign the flower head is more mature and won’t last as long as other flower heads that don’t have visible pollen stains.
    • Callas last well in a bouquet so long as they are fully hydrated before they are arranged.

  • Question
    Do planted calla lilies only bloom only once per season, or do they keep blooming?
    Community Answer
    When we were in Southern California, they bloomed several times a year as it never got cold enough to knock them out. We brought a suitcase full of them to Oregon 30 years ago; the same plants are in full bloom right now, but in a few weeks of warm weather they will be gone until next spring. Foliage might come back in fall, but no flowers.

  • Question
    Why did the tops of my new bouquet of roses and calla lilies start to turn brown on the second day?
    Community Answer
    They could not be fresh. They should be picked the day you're giving them to someone. Keep them in fresh water in a cool area to help them live longer.

      About This Article

      Article Summary X

      With the right maintenance, you can keep your cut calla lilies fresh for longer. Put your lilies into a vase filled 2/3 of the way with water as soon as possible so they don’t dry out. If you need to cut the stems to fit in the vase, cut them at a 45-degree angle to help them absorb water. Add a little flower feed or a teaspoon of sugar to the water to give them the nutrients they need. Keep your lilies somewhere cool and away from direct sunlight. Replace the water every day or 2 to keep it clean. Every 2 or 3 days, you should also trim half an inch off the bottom of their stems so they can continue to absorb water.
