🌸 Cut Flower Garden Planning Guide
Use this detailed guide to plan, grow, and care for your cut flower garden all season long. Below you’ll find a printable planting schedule and a flower care chart to help you grow blooms that last beautifully in the vase.
🌱 Cut Flower Garden Planting Schedule
Here’s a seasonal guide for when to sow seeds indoors, transplant outside, or direct sow into the garden for maximum blooming time.
| Flower | Start Indoors | Direct Sow Outdoors | Days to Bloom | Successive Planting |
|---|---|---|---|---|
| Zinnias | ✘ | After last frost | 60–75 days | Every 2–3 weeks |
| Sunflowers | ✘ | After last frost | 60–90 days | Every 2 weeks |
| Cosmos | ✘ | After last frost | 75–90 days | Every 3 weeks |
| Snapdragons | 6–8 weeks before last frost | After frost (if hardened off) | 110–120 days | No |
| Marigolds | 4–6 weeks before last frost | After last frost | 50–60 days | Optional |
| Sweet Peas | 6–8 weeks before last frost | Early spring | 60–70 days | No |
| Bachelor’s Buttons | ✘ | As soon as soil is workable | 60–70 days | Optional |
| Celosia | 6–8 weeks before last frost | After frost | 90–100 days | Optional |
Pro Tip: Adjust these times to match your USDA hardiness zone. If you’re not sure of your local last frost date, check your region’s average using a frost date calculator. The Farmers Almanac is the best resource I have found for accurate growing zones and I highly recommend you explore their site.
💐 Cut Flower Care Chart
To make the most of your blooms indoors, harvest at the right stage and follow simple vase care practices. This chart breaks it all down by flower type:
| Flower | Cutting Stage | Vase Life | Care Notes |
|---|---|---|---|
| Zinnias | When fully open | 7–10 days | Strip lower leaves; change water daily |
| Sunflowers | When petals just open | 5–7 days | Harvest early; use flower food to extend life |
| Cosmos | When petals begin to unfurl | 5–7 days | Very delicate; harvest carefully |
| Snapdragons | Bottom blooms just opening | 7–10 days | Strip lower leaves; change water frequently |
| Marigolds | Fully open blooms | 5–7 days | Strong scent; pair well with sturdy flowers |
| Sweet Peas | Lower blossoms open | 4–5 days | Cut often for more blooms; very fragrant |
| Bachelor’s Buttons | Fully open | 4–6 days | Good for fresh or dried arrangements |
| Celosia | When fully colored | 10–14 days | Long-lasting and unique texture |
Quick Care Tips:
- Harvest in the cool of morning or evening.
- Use sharp, clean snips to avoid crushing stems.
- Remove any leaves that will sit below the water line.
- Change water every 1–2 days for longest vase life.
