Find The Best Time To Plant For Springtime – Complete Seed Starting Guide

Written by – Kaitlynn from MIgardener

You have finished mapping out your garden for this year, but now it’s time to figure out when to start your seeds. Finding the perfect time to start seeds might be intimidating for beginners. But a word of advice from the experts; starting seeds indoors is a complete luxury and not a necessity to see fruitful (haha) results from your garden. Your garden can be just as successful without starting seeds indoors, and some varieties do better direct sown in the first place!

If you have the space in your home, an area with a good amount of sunlight, and the time to start your seeds in advance, here’s how to get started. We’ll also cover what types of plants don’t do well when started indoors. With this guide you’ll find that working out your perfect seeds starting time is simple.

Step 1: Last Frost Date

Timing is everything when it comes to seed starting. It’s important to find the last frost date in your area in order to give your seedlings the time they need to mature for transplanting. There are a handful of ways to find last frost dates online and in person. Our new garden planner comes with a last frost chart that you can use as a guide for your area. You can look up last frost dates online that are more specific to your location on the Old Farmers Almanac. For our international readers, google is a straightforward resource to find your last frost date by looking up your nearest big city.
