What vegetables can you plant now? The answer depends on your location, frost dates, soil temperature, and current weather—not just the month. Use this month-by-month guide as a flexible roadmap for planning, planting, harvesting, and protecting a vegetable garden, then check a regional planting calendar before choosing exact crops or dates.
When should you start planting your vegetable garden?
Start with your local growing conditions, not a national calendar. Frost dates help define the season for many crops, while soil temperature and recent weather determine whether a particular bed is ready. The Oregon State University (OSU) guide for the Willamette Valley recommends using a soil thermometer and cautions that weather may delay planting; it also says gardeners elsewhere in Oregon should adjust its dates to local conditions. See OSU’s vegetable gardening guide.
Before deciding what to sow or transplant, check these factors:
- Your frost window: Find your local average last spring frost and first fall frost. Penn State advises gardeners to know both. Its Lancaster County example is USDA Zone 6B, with an April 28 last frost and October 11 first frost; those dates are specific to that example, not a general planting schedule. Penn State’s succession-planting page gives the example.
- Soil temperature and weather: A calendar date alone cannot tell you whether your soil is warm enough. A soil thermometer can help; follow local guidance for the crops you intend to grow.
- Crop and planting method: Frost tolerance and whether a crop is direct-seeded or transplanted affect its timing. The University of Minnesota Extension guide separates planting windows by crop and advises waiting until after its local last frost to transplant specified warm-season crops. See its Minnesota planting guide.
- Your region: A calendar for Central Oregon, the Willamette Valley, Philadelphia, or Minnesota reflects different conditions. Use a guide written for your area rather than transferring another region’s dates. Regional examples include OSU’s Central Oregon calendar and Penn State’s Philadelphia planting guide.
Vegetable gardening month by month
This annual outline follows tasks highlighted in OSU’s monthly garden calendars. OSU notes that its recommendations may not apply to every part of Oregon. Treat the tasks as seasonal prompts, not universal sowing dates; choose crops and timing from a locally appropriate guide.

January: Plan and check the soil
Review your garden layout, decide what you want to grow, and compare seed choices with the space and season you have. Consider a soil test before making amendments. In some climates, protected seed starting may be possible, but early indoor sowing is a specialized option rather than a default: the Willamette Valley guide notes that it can require bottom heat and supplemental light.
February: Keep planning; start selectively
Continue seed and bed planning, and maintain tools and growing spaces. Some regions may allow protected starts or limited direct sowing later in the month, but do not borrow those dates without checking local guidance. Indoor starts made this early may need both suitable warmth and supplemental light.
March: Prepare the summer plan
Finalize the summer garden and identify which crops can be started early in your region. Where soil and weather permit, begin locally recommended early sowings or protected starts. OSU’s monthly collection highlights March as a time to plan the summer vegetable garden.

April: Prepare beds and make suitable cool-season plantings
Work on soil and raised-bed preparation, then make cool-season sowings or transplants when local conditions are appropriate. April crop windows differ by region, so check a planting guide that matches your location rather than relying on the month alone.
May: Check the soil before warm-season planting
Check soil temperature, establish irrigation, and plant warm-season crops only when local conditions allow. In Minnesota, the Extension guide advises waiting until after the local last frost—described there as mid-to-late May—before transplanting specified warm-season crops. That timing applies to the Minnesota guidance, not to other regions.
June: Maintain moisture and harvest as crops mature
As temperatures rise, pay attention to watering and harvest crops when they are ready. OSU highlights watering as a June task in its Oregon calendar; harvest timing depends on the crop and local growing conditions.

July: Consider crops for fall and winter harvest
Keep plants watered and check whether your remaining growing season can support additional plantings. In suitable Oregon contexts, OSU identifies July as a time to begin planting vegetables for fall and winter harvest. Use a regional calendar to determine which crops and dates fit your area.
August: Watch water needs, pests, and heat
Prioritize irrigation and inspect plants for pest problems. Where heat threatens plants, temporary shade or protective covers may help; choose a response suited to your local conditions and the crop.

Late-summer conditions vary. Some Oregon areas may still face heat, while others need to prepare for frost and wind. Adjust watering and protection to the weather where you garden.

October: Harvest, save seed, and prepare for the next season
Harvest mature crops, including squash when ready, and save seed where appropriate. Check that seed is suitable to save and store it properly for future use.
November: Clear debris and protect suitable plants
Remove garden debris and cover plants that are suited to overwintering in your region. Choose protection based on local frost and winter conditions rather than assuming every crop should remain in the bed.
December: Check drainage and stored produce
In wet conditions, watch for drainage problems and rot, and check stored produce. Use the quieter season to plan garden maintenance and next year’s layout.

Instead of sowing an entire crop at once, plant another small batch after the first planting. Penn State describes repeating a planting approximately two or more weeks after the first one, and also recommends using an area for a new crop after an earlier crop is harvested. The interval is a technique, not a universal schedule: adapt it to the crop, local season, and remaining time for growth. See Penn State’s succession-planting guidance.
To put the approach into practice:
- Check a local planting guide to confirm that the crop can still mature in the available season.
- Sow a manageable first batch rather than filling every available space at once.
- About two or more weeks later, consider sowing another batch if the crop and local growing window support it.
- When an earlier crop is harvested, use the open space for a locally suitable follow-on crop.
How to choose a calendar that fits your garden
When comparing planting plans, check the location and frost window first. Then compare what each guide says about crop frost tolerance, direct sowing versus transplanting, soil-temperature needs, repeat sowings, and fall crops. A regional calendar is useful when its assumptions resemble your garden’s; it is not a promise that the same dates will work elsewhere.
