Garden Planning, Succession & Crop RotationCut Flower Garden Calendar
A cut flower garden works when something is ready to cut every week. That means sorting flowers by cold tolerance, staggering sowings and planning perennials and annuals together.
Key points
- Sort flowers into hardy, half-hardy and tender and tie each to your frost date.
- Count back from the last frost for indoor starts.
- Stagger sowings and mix annuals with perennials for steady cutting.
- Cut at the right stage into clean water.
- Follow pesticide labels and protect pollinators.
How do you sort cut flowers by hardiness?
Flower growers commonly sort annuals into hardy, half-hardy and tender groups. Hardy types tolerate cold and can go out early, half-hardy types tolerate a light chill, and tender types need warm weather and no frost.
Look up each flower in an extension or grower resource, because the group affects when you can sow or transplant. Tie each group to your own last frost date.
Some growers also sort flowers by day length response, since a few kinds bloom early or late depending on the length of the day. Look this up for each flower you grow. A few extra plantings of hardy types in the fall, in regions where that works, can give earlier spring flowers, but check local guidance first.
When do you sow and transplant?
Some flowers do best sown directly, and others need an indoor start so they bloom in time. Seed packets and extension guides give the lead time. For example, if a flower needs a number of weeks indoors before transplanting, count backward from your last frost date.
Frost dates vary a lot by location, so use your local records from the National Weather Service or your county extension office. Keep seed starting records, including sow date, germination date and transplant date. After a season you will know exactly how many weeks each flower needs from seed to first cut in your conditions.
How do you stagger blooms for a steady supply?
Make repeat sowings of fast annuals, mix early and late varieties of the same flower and add perennials and shrubs for the shoulder seasons. List what blooms in each month and look for empty weeks.
For market growers, a harvest log shows which flowers sold well and when supply ran short, which is the best planning tool for the next year. Note the dates of first and last cut for each flower, which shows exactly how long each variety lasts and when you need the next planting ready.
- Repeat sowings of fast annuals
- Early and late varieties of the same flower
- Perennials and woody stems for early and late weeks
What do cut flowers need while they grow?
Most cut flowers want full sun, fertile soil and steady water. Use a soil test to guide fertilizer, and follow local nutrient management rules. Many need support, such as netting, so stems grow straight.
Pinching young plants of some kinds encourages more and longer stems. Check the specific flower for that advice.
Weed control early in the season pays off, since young flower plants compete poorly. Mulch or woven ground cover are common choices, depending on your setup.
How should you harvest and condition stems?
Cut at the stage recommended for each flower, often in the cooler part of the day, and place stems in clean water right away. Use clean buckets and clean cutting tools, because bacteria shorten vase life.
Cold storage and flower food are options for market growers. Your extension service can give crop-specific harvest stage and handling advice. Wash and sanitize buckets between uses. Stems left in dirty water can clog and wilt quickly, which hurts quality whether you sell flowers or bring them home.
How do you plan the layout and rotation?
Plant in blocks or rows that are easy to reach from a path, so you can cut without trampling. Keep tall, supported flowers where they will not shade shorter ones, and give each flower the spacing recommended for good air flow.
Rotate annual flowers as you would vegetables. Planting the same flower family in one spot year after year can build up disease and pest problems, so keep a map and move them. Leave room for supports and for the width of the paths, so tall plants do not flop across them after a storm.
What about pests, pesticides and selling?
Scout often and start with cultural controls. If you consider a pesticide, ask extension for current recommendations, read the label closely and protect pollinators, since flowers attract bees. Licensing for applicators varies by state.
If you sell flowers, check state and local rules on sales, taxes and any permits. Your state department of agriculture can point you to what applies.
Keep a short record of which flowers had pest trouble and when, which helps you scout earlier the next year.
