Cut Flower Succession Planting: A Working Template
The difference between a hobby patch and a flower business is succession. Here's the template I wish I'd had in year one.

Why succession is the whole game
One big planting of zinnias gives you four glorious weeks and then a dead bed for the rest of the season. Three plantings 14 days apart give you 10–12 weeks of harvest from the same square footage. Same seed, same bed prep — the only difference is staggering.
The 14-day rule (with exceptions)
For most heat-loving annuals (zinnia, cosmos, celosia, amaranth), sow every 14 days starting at your last frost date and stop ~75 days before your first fall frost. Cool-season crops (snapdragon, bachelor button, bupleurum) follow a similar rhythm but start indoors 6–8 weeks before last frost.
Two crops break the rule:
- Sunflowers (branching) — succession every 7–10 days. They bloom fast and stop, so tight intervals keep the stand full.
- Lisianthus & ranunculus — one main planting per year; they don't respond well to summer heat in most zones.
A worked example: Saturday market, August 3 (Zone 6b)
If your peak sale date is August 3, work backwards. Most workhorse annuals need 60–90 days from sow to first cut — so the first indoor sowing has to land in mid-March.
- March 15 (indoors) — snaps, lisianthus, statice
- April 5 (indoors) — zinnia round 1, celosia round 1
- April 26 (last frost, direct) — cosmos, sunflowers, zinnia round 2
- May 10 — zinnia 3, sunflower 2, cosmos 2
- May 24 — sunflower 3, amaranth, zinnia 4
- June 7 — final cosmos and sunflower for September
Pinch your branching annuals
Hard-pinch zinnias, cosmos, snapdragons, and celosia at the first 4 sets of true leaves. You trade 7–10 days of bloom delay for a 2–3× increase in stem count per plant. On a 4'×8' bed, that's the difference between 200 stems and 600.
Net early, net once
Flower-support netting is the cheapest insurance in the business. Install it as soon as transplants go in the ground — never after they've already flopped. Two layers 9–12" apart for snapdragons and lisianthus, one layer for cosmos and zinnias.
