How to Create a Year-Round Growing Schedule
A year-round growing schedule turns a seasonal hobby into a steady income stream. With cold frames, hoop houses, and indoor microgreens, you can harvest something every month. This guide shows how to build a schedule that spans all four seasons.
| Season | Outdoor Crops | Protected Crops | Indoor Crops |
|---|---|---|---|
| Spring | Lettuce, peas, spinach, radishes, carrots | Early tomatoes, peppers (in hoop house) | Microgreens, herbs |
| Summer | Tomatoes, peppers, beans, squash, cucumbers | Shade cloth for greens | Microgreens |
| Fall | Kale, broccoli, lettuce, spinach, carrots | Cold frame greens, late tomatoes | Microgreens |
| Winter | Overwintering garlic, parsnips | Spinach, lettuce, kale in cold frame/hoop house | Microgreens, herbs, sprouts |
Why Year-Round Matters for Profit
Most backyard growers harvest for 4–6 months. Extend to 10–12 months and you double potential revenue. Winter greens and microgreens sell at premium prices when outdoor supply drops. Customers at farmers markets pay more for fresh lettuce in January. Use the profit estimator to model extended-season returns.
Cold Frames: Low-Cost Season Extension
Cold frames are bottomless boxes with a clear lid. They trap heat and protect plants from frost. A simple wood frame with an old window or plastic sheet works. Place facing south for maximum sun.
- Extend fall harvest by 4–8 weeks
- Start spring plantings 4–6 weeks earlier
- Grow spinach, lettuce, kale, arugula through winter in mild zones
- Vent on warm days to prevent overheating
Pair cold frames with your seasonal planting calendar. Plant fall greens in September for harvest into December. Start spring lettuce in February for April harvest.
Hoop Houses and Row Covers
Hoop houses (low tunnels) are plastic or fabric stretched over bent pipes. They offer more headroom than cold frames and protect larger areas. Row covers are lightweight fabric laid directly over plants.
- Hoop houses: 6–10°F warmer than outside; protect tomatoes and peppers into late fall
- Row covers: 2–4°F warmer; protect lettuce, spinach, broccoli from light frost
- Both need ventilation on sunny days
See raised bed vs in-ground to decide where to place protection. Raised beds warm faster and work well with hoop houses.
Indoor Microgreens: True Year-Round Revenue
Microgreens grow indoors with no outdoor space. Harvest in 7–14 days. They sell for $15–40 per pound. A 10 sq ft setup can produce hundreds of dollars per month. Our microgreens guide covers setup, seeds, and harvest schedules.
Add microgreens to your year-round schedule as the backbone of winter income. When outdoor harvests stop, microgreens continue. Stagger trays every 3–5 days for continuous supply.
Building Your Schedule: Month by Month
January–February
Indoor: microgreens, herbs in windowsill. Outdoor: plan and order seeds. Cold frame: overwintering spinach and kale if planted in fall.
March
Start tomatoes, peppers indoors. Direct sow peas, spinach, arugula in cold frame or as soon as soil thaws. Microgreens ongoing.
April–May
Transplant warm-season crops after last frost. Succession plant lettuce and greens. Use succession planting for steady harvests.
June–August
Full outdoor production. Add shade cloth for cool-season greens in summer. Microgreens continue indoors.
September–October
Plant fall greens, garlic. Extend tomatoes and peppers with hoop house. Cold frame planting for winter harvest.
November–December
Harvest cold frame greens. Rely on microgreens for sales. Plan next year using crop rotation.

Cold-Hardy Crops for Winter
| Crop | Min Temp (approx.) | Harvest Window |
|---|---|---|
| Spinach | 15°F | Late fall–early spring |
| Kale | 10°F | Late fall–early spring |
| Lettuce (certain varieties) | 20°F | Late fall–early winter |
| Arugula | 25°F | Late fall–early winter |
| Claytonia | 10°F | Winter |
| Mache | 5°F | Winter |
Final Tips
Start with one extension method. A single cold frame or a few microgreen trays proves the concept. Add hoop houses and more indoor space as revenue grows. Track costs and harvests with our calculators. A year-round schedule takes planning but pays off with steady income and loyal customers.
Frequently Asked Questions
What can I grow in a cold frame in winter?
Spinach, kale, lettuce, arugula, Claytonia, and mache can grow in cold frames through winter in zones 5–7. Growth slows but continues on sunny days.
How much does a hoop house cost?
Small DIY hoop houses cost $50–200 for materials. Larger walk-in structures run $300–1,000. Commercial-grade hoop houses cost more but last years.
Can I grow vegetables year-round without a greenhouse?
Yes. Cold frames and hoop houses extend outdoor harvest. Microgreens and herbs grow indoors. Combined, you can harvest something every month.
When should I start my year-round schedule?
Start planning in winter. Order seeds, build cold frames, and set up microgreen trays. Begin planting as soon as soil is workable or indoors anytime for microgreens.
