Zones 3-4 Planting Schedule

    When to Plant Vegetables For Zones 3-4

    Each USDA planting zone has its own schedule for sowing seeds. If you're new to vegetable gardening, you'll want to know that there is a right time to sow each variety of vegetable seed. By following our zone chart for both cool and warm season vegetables, you'll be sure to sow your seeds in the correct window of time, enabling optimum sprouting and yield. And don't forget, the seeds you pick are also of the greatest importance. Even if you are an old hand in the vegetable garden, we hope that our USDA zone planting chart will be a useful tool for organizing your spring and summer vegetable planting.
