When to Cut FreshFlowers
Cut garden flowers in early in themorning or early evening, when temperatures are cool and the stalks are filled with water. Midday heat is stressful to plants, causing them to wither more readily when cut.
For most flowers,avoid picking when in full bloom or they won’t last as long; pick when they are just starting to show color. (Note: This isn’t true of roses, which do not continue to develop.)
How to Cut Flower Stems forVase
Always use a sharp knife. Avoid scissors, which can pinch the water channels of the stalks.
Place the stems straight into a bucket of clean, tepid water (not cold water) as soon as possible after cutting.
If possible, leave the flowers in their bucket of water in a cool, dark spot for a few hours to let them stabilize before arranging. Even better, leave them overnight.
Keep flowers as cool as possible, but avoid putting them in your fridge, if you can. Florists’ coolers range from 33° to 40°F, so your fridge likely won’t be cool enough and any fruit or vegetables could emit ethylene gas, which shortens the life of cut flowers.
Selecting aVase
Use a vase that’s large enough to provide plenty of room for all the stems, with a mouth that’s wide enough to allow for good air circulation.
Always use a thoroughly clean vase as bacteria can survive in dirty vases and your flowers may not last as long.
10 Tips on How toCut Flowers for aVase
Strip all the leaves from the bottom half to two-thirds of each stem. Do not leave any leaves below the water line, as they could rot and ruin the quality of the water.
Re-cut the stems at an angle.Aslanted cut helps if you are using floral foam; a stem with a point is easier to insert.Cut flower stems at an angle also prevents the stem resting on the bottom of the vase and sealing itself over. Angular cuts also great a larger surface area for water uptake.
Cut stems underwater if you wish to shorten the stems on cut flowers before arranging them; otherwise, the stem can take in too much air, causing a blockage that keeps water from the flower. (This is especially true of roses.) Floral supply companies sell underwater cutters; or you can cut a flower in the garden, immediately submerge the stem in warm water, and cut it again in the house while holding it below the water line.
Poppies, milkweed, and other flowers with milky stems should be held in a flame for about 15 seconds immediately after cutting. This seals the latex in the stem but keeps the water-conducting vessels open. Without searing, the latex substance can leak into the water and cause it to spoil quickly. It can also affect the life of other flowers in the vase.
Don’t crush the stems. If you have a woody stem—on lilacs, for example—just cut above the stem. For years, flowers use to use mallets to crush the stem; In fact, pounding the stems makes the stems rot faster in the water. If you can’t cut above the woody stem, submerge the entire stem in water for 20 minutes to an hour before cutting.
Don’t use cold water. Flowers like to be warm and prefer water that is 80° to 110°F. The water in the vase does not need to be maintained at that temperature, but always start cut flowers in warm, not cold, water.Cold water has a higher oxygen content, which can cause air bubbles to form in the stems of your flowers, blocking their water uptake. Spring bulbs such as tulips and daffodils are the exception to this rule as they prefer to be placed in cold water.
Add a tablespoon of sugar to nourish flowers. Some florists use a splash of bleach to inhibit bacterial growth (just ¼ teaspoon per litre of water). Both extend the life of the flowers.
Do NOT put cut flowers in full sun. Display the bouquet away from direct sunlight, heat, orhot and cold drafts. Also, position vaseaway from fruit bowls.
- Check the vase each day. Remove any dead or fading blooms to prevent bacteria damaging the healthyflowers.
- Change the water every few days, refreshing any flower feed aswell.
How Long Do Cut FlowersLast
- Dianthus (including Carnations, Pinks and Sweet Williams) are some of the best known of all cut flowers. They last 14 to 21days!
- True Lilies such as Oriental Lilies last 8 to 10 days and add dramatic flair. When cutting lilies in the garden, leave a third of the lower stem.Note: Daylilies (which not true lilies) are not cutting flowers; they don’t last more than oneday.
- Sunflowers and gladiolus both have a vase life of 7 to 10 days, and both make great cutflowers.
- Chrysanthemums last for a week ormore.
- Tulipshave a vase life up to 7 days; they continue to grow after you arrange them. (Some flowers, such as daffodils, contain a type of sap that will shorten the vase life of other flowers. Tulips don’t mix withdaffodils.)
- Peonies last 5 to 7 days. (Note: Take no more than a few blooms from each peony plant and avoid cutting stems from plants that are less than three yearsold.)
- Sweet peas last 3 to 7 days and add nice height to a flower arrangement. The more you cut your sweet peas in the garden, the more they willbloom!
Here are reader favorites from the flower cuttinggarden:
- In May to July: Narcissus, Tulips, Peony, Snapdragon,Butterfly Ranunculus,Salvia.
- July to September:Sunflowers, Zinnia, Cosmos, Rudbeckia, Dahlias, Stock, Asters, Statice,Amaranthus

I am an amateur and I was wondering about some of the wildflowers I tried to pick. I don't know what most of them are called. But there's tons of what I think we're called black-eyed Susan's when I was a kid. I don't think they last very well in vases if I remember right. Then there's some strange yellow ones that have little yellow flowers at the top I was going to post a picture here but I don't know if I can. A tall little ones with yellow flowers at the top, and then there's like Goldenrod, and then there's some purple ones, and some white ones that eventually do a weird thing and look like they're evolving into a planet with lines from the North Pole to the South Pole and little pieces of fuzz, and then there's a thistle, big huge thistle bushes that grow purple flowers. Those can be a little bit hazardous. But I'm wondering if a nice Arrangements of these were put together would anyone actually buy them at some kind of sale or something? Some people just call them weeds of course. And or could they be dried for later?

Hi Randal, Yes, black-eyes susans are outstanding cut flowers. At farmers’ markets, there are often bouquets for sale! The price seems to range from $1 a flower to $7 a bouquet. Quite a range. Usually, they feature “cutting flowers” such as zinnia which last a long time in a vase. Other options are sunflowers andcosmos.
