Vegetable Planting Calendar by Climate Zone
The Planting Calendar shows the best time to plant vegetables, herbs, and flowers based on your climate zone. Pick your zone and read a clear monthly grid that tells you when to start seeds indoors, sow directly, transplant seedlings, and harvest each crop.
It is built for home gardeners, urban growers, and anyone planning a new garden — whether you are sowing your first bed or adjusting to a new region. The calendar covers 63 plants across six climate zones, so you always have a quick reference for what to plant this month.
How to Use the Planting Calendar
Select your climate zone
Use the Climate Zone dropdown to choose Tropical, Subtropical, Temperate, Mediterranean, Arid / Desert, or Continental. The whole grid updates instantly to show planting windows for that zone.
Browse, filter, or search
Scroll the grid to see every plant, switch the All / Vegetables / Herbs / Flowers tabs to narrow the list, or type a plant name in the search box. Filters and search work together.
Read the colored bars
Each row is a plant and each column is a month. A bar means an activity is recommended: Indoor Start, Direct Sow, Transplant, or Harvest. The current month column is highlighted so you can see what is relevant right now.
Open a plant for details
Click any plant row to open a popup with its maturity time, sun and water needs, spacing, a "This month" tip for your zone, and a per-plant mini calendar that breaks the schedule down by activity.

Frequently Asked Questions
What vegetables can I plant this month?
Select your climate zone, then look at the highlighted current-month column. Any plant with a colored bar in that column has an action this month. Click the row to see whether it is time to start seeds indoors, direct sow, transplant, or harvest.
How do I find my climate zone?
Tropical is hot and humid all year (Southeast Asia, Central Africa). Subtropical is warm with mild winters (southern US, southern China). Temperate has four distinct seasons (UK, central Europe, Japan). Mediterranean has dry hot summers and mild wet winters (Mediterranean coast, California). Arid / Desert is very hot and dry (Middle East, southwest US). Continental has cold winters and short warm summers (Russia, Canada, Scandinavia).
When should I start seeds indoors versus sow outdoors?
Indoor Start means beginning seeds in containers or a greenhouse before the outdoor season, giving plants a head start before you transplant them out. Direct Sow means planting seeds straight into the garden. The calendar shows both: indoor starting matters most in Temperate and Continental zones where the outdoor season is short.
Why are some months empty for a plant?
An empty month means that activity is not recommended then for your selected zone. For example, tomatoes in temperate zones have no Direct Sow entries because they should be started indoors and transplanted rather than sown straight outside.
Can I plant outside the recommended months?
The grid shows optimal windows based on general climate patterns. Local microclimates, elevation, and weather can shift them by a few weeks, so treat the calendar as a guideline and adjust to your own conditions — especially your last and first frost dates.
Why do some plants show very long maturity times?
Tropical perennials such as ginger and turmeric naturally take roughly 8–10 months (240–300 days) from planting to harvest because they grow slowly. By contrast, fast crops like radish can be ready in just 22–35 days.
What does the spacing value mean?
Spacing is the recommended distance in centimeters between individual plants. A spacing of 50 cm means each plant should sit at least 50 cm from its neighbors. Proper spacing gives every plant enough airflow, sunlight, and root room for healthy growth.
