A little knowledge. A growing garden.

Good timing starts with your garden.

What can I plant now? The answer starts with the month, but ends with the conditions outside your door. Use this monthly planting guide to make a shortlist, then let your soil and local forecast have the final say.

01 / FIND YOUR START

How the tool works

Enter a US ZIP or choose a USDA zone. We use the Garden Calendar’s zone lookup and broad seasonal planting guidance to suggest outdoor crops, indoor starts, things to wait on and conditions to watch. Empty categories are explained.

02 / KNOW YOUR ZONE

Winter hardiness is one clue

USDA zones describe average winter minimum temperatures. They help you choose perennial plants that may survive winter. They do not tell you the last spring frost, the first fall freeze or how hot your garden gets.

03 / CHECK YOUR CONDITIONS

Plant for the weather you have

Before sowing, check soil temperature, drainage, local frost timing and the variety’s days to harvest. Elevation, coastal influence and sheltered beds can shift timing. Harden off indoor seedlings before transplanting.

A few things gardeners ask

What should I plant now?

Start with crops suited to your current growing conditions. Cool-season vegetables such as lettuce, spinach and radishes need cooler conditions; beans, squash and basil need warmth and a frost-safe window. Enter your ZIP or USDA zone for a monthly starting point, then check local conditions before planting.

What can I plant in September in zone 9b?

Cool-season vegetables can be candidates as heat eases. Carrots and spinach are examples to check against your local calendar. Zone 9b spans different climates, so September planting in inland California can differ from coastal or southeastern gardens. Check seedbed temperature, water availability and the time left to harvest.

Why does USDA zone matter, and is it enough?

USDA zones describe average annual extreme minimum winter temperatures, which help assess perennial winter hardiness. They do not give first or last frost dates. Local heat, elevation, rainfall, soil temperature, day length and microclimates all affect planting time.

How does the ZIP code lookup work?

We reuse the Garden Calendar’s stored ZIP-to-zone table. A ZIP can cover several microclimates, so treat the match as a starting point and confirm your garden on the USDA map. Some ZIPs are missing; you can choose a zone manually. An optional place-name lookup adds a city label without changing the planting guidance.

Can I print without an account or email?

Yes. Results and Print / Save PDF are free with no account or email required. An optional name personalizes the sheet and stays in this page’s browser memory. QR links contain only the USDA zone and month, never your name or ZIP.

Which month and locations does the tool cover?

The default month follows the site’s America/Los_Angeles clock. You can choose another month or restore one from a QR link. The tool provides broad Northern Hemisphere guidance for USDA zones 3–11. Zones 12–13 show a clear data limitation and regional resources instead of an invented crop schedule. This is not a live weather or frost forecast.
