Vases full of fresh cut flowers add a beautiful and positive
touch to almost any space. Having great cut flowers in your
home all through the local growing season is within the
reach of every gardener if you will just follow a few simple
1. While some bedding plants make decent cut flowers,
using varieties that are specifically bred for cutting will
increase your success many fold. Some flower varieties
are too short for most vases and many simply will not hold
their looks once cut.                                                    “Double type sunflower, Double Solar cv.”
2. Cut flowers require sufficient water for their stems to
stretch. One of the best ways to grow dwarf cut flowers is
to withhold water at the critical time when they are getting
tall. Using soaker hose or an irrigation system is the simplest
way to get plenty of water to your flowers roots. See
HortReport, Garden Enthusiast Series #1 “Building and
Operating a Home Fruit & Vegetable Garden Irrigation
System” for more information.
3. Every other year, test your soil fertility. Proper plant
nutrition will result in more flowers that last longer once
4. Finally, know the best growth stage (partially open or
fully open) to cut each flower.

In general, if you look for the scissors icon in your seed catalogs or on seed packets you’ll have varieties that are better
suited to a cutting garden. These varieties have stems long enough to make cutting them useful. They should also have
better vase life than bedding types. Most flowers will continue to push additional blooms from healthy plants if you keep
cutting them. The best method to apply water is by using drip, trickle or soaker hose to the plants root system. Not only
do you get more water where it is actually needed and waste very little, but your flowers will be look better when kept dry
as much as possible.

The last step to great cut flowers is in knowing how to handle your flowers once they are cut. Try to cut them after the
morning dew is dried off but before the heat of the day has soaked in. This will prevent mildewing of the flowers and
stems while avoiding unnecessary cooking of the blossoms. Be sure to immediately place the cut flowers into clean
water in clean buckets. Use a solution of one part household bleach to nine parts water to clean your buckets and
prevent disease buildup between uses. The water that the flowers actually go into should be acidified. Recut flower
stems as you prepare them for a vase in order to insure that they have fresh tissue exposed to take up water. You can
either use floral preservative (follow label directions) or add citric acid. 1 Tablespoon of powdered citric acid (available
from bulk food suppliers) will acidify 4 gallons of water enough to greatly improve vase life. Floral preservatives have the
added benefit of supplying a little carbohydrate (sugar) which will help unopened buds to open along with bactericides
which will help to keep the water clear. There are many home recipes available to make your own floral preservative;
none work as well as the commercial preparations when mixed properly. Do not be tempted to stretch a floral preservative
by adding extra water. This usually results in substantially shorter vase life as there is enough carbohydrate present to
feed the bacteria, but not enough bactericide to control them.
