Why ChatGPT?
ChatGPT's combination of horticultural knowledge and structured planning ability makes it ideal for building personalized planting calendars. It handles USDA hardiness zones, frost dates, companion planting logic, and succession planting schedules — tasks that normally require a professional garden designer.

You are a professional garden designer and horticulturist specializing in kitchen gardens and ornamental beds. You create seasonal planting plans that maximize yield, succession, and visual interest.
My garden details:
- Location and hardiness zone: {{location_zone}}
- Last frost date / first frost date: {{frost_dates}}
- Garden space: {{garden_space}}
- Sunlight: {{sunlight}}
- Soil type: {{soil_type}}
- Water access: {{water_access}}
- What I want to grow: {{grow_preferences}}
- Experience level: {{experience_level}}
- Goals: {{goals}}
Create a seasonal planting calendar with:
1. **What to plant each month** — organized as a 12-month calendar, noting direct sow vs. start indoors vs. transplant
2. **Companion planting pairings** — for my chosen plants, which should go next to each other and which should be kept apart
3. **Succession planting schedule** — for any crops with short harvest windows (lettuce, radish, herbs), when to sow a second batch
4. **Space allocation** — given my dimensions, which plants get how much space (with square-footage estimates)
5. **Beginner traps to avoid** — 3 common mistakes for my specific plant selection and conditions Make it yours Fill in 9 fields to get a tailored prompt Customize ↓
Example (filled in)
Location: Portland OR, Zone 8b | Frost: last Mar 15 / first Nov 1 | Space: two 4x8 raised beds | Sunlight: full sun | Soil: loamy | Water: hand watering | Grow: tomatoes, basil, lettuce, zucchini, herbs | Level: beginner | Goal: fresh vegetables April-October
Sample AI Output
12-MONTH CALENDAR (Portland 8b):
Jan-Feb: Start tomatoes indoors (8 weeks before transplant) / order seeds
March: Direct sow lettuce + spinach (cold tolerant) / transplant out after Mar 15
April: Transplant tomato seedlings / sow basil indoors (needs warmth)
May: Transplant basil outside / direct sow zucchini after soil warms to 65°F
June-August: Succession sow lettuce every 3 weeks (bolts in heat — use shade cloth)
Sept-Oct: Final tomato harvest / sow fall spinach for October cut
Nov-Dec: Rest beds / add compost layer
COMPANION PLANTING:
- Tomato + Basil: plant within 30cm — basil deters aphids, improves tomato flavor (evidence mixed but zero downside)
- Tomato + Zucchini: keep 60cm apart — both large, will compete for space
- Lettuce UNDER tomatoes: once tomatoes are 60cm tall, lettuce benefits from partial shade in summer heat
BEGINNER TRAPS:
1. Planting zucchini too early: soil below 65°F causes stunted growth that never recovers
2. One tomato transplant at a time: start 3-4 seedlings in case of spring frost damage
3. Overplanting: one zucchini plant produces more than most families can eat
Tips for Better Results
Give ChatGPT your exact last and first frost dates (check almanac.com/gardening/frost-dates for your zip code) — these are the anchors for the entire planting calendar. If you have a photo of your space, describe the dimensions and sun direction in detail.
