Common questions
Most seeds should be started indoors 6 to 8 weeks before your last frost date. Tomatoes, peppers, and eggplant benefit from an early start (8 to 10 weeks before last frost), while cucumbers and squash only need 3 to 4 weeks. Check the indoor start dates in our calculator above for timing specific to your ZIP code and frost dates.
