Indoor Seed-Starting Calendar

Aerogarden seed starting

I know it seems spring is far, far away in January. Luckily for us gardeners we get to start spring early! End of January into February is seed starting time indoors. I have outlined by month the plant seeds to start indoors between now and April for our Zone 6 garden.

Many big box stores will begin getting in their seeds this month. There are great varieties that can be ordered on line. Some of my favorites are Abundant Life, Territorial Seed Company, High Mowing Organic Seeds, Johnny’s Selected Seeds. Territorial Seed gives a month by month planting guide along with detailed growing guide. Johnny’s gives a seed germination temperature guide. They will send you free catalogs or you can go on-line to visit their web page. High Mowing is offering free shipping this season.

Here is a a map that shows where many seed companies are located.

Seed packets will tell you how far in advance of your last frost date to start your seeds indoors. Look up your last frost date at Moon Garden Calendar.

January and February are cold season crops seed starting time. March and April is the time for warm season veggie and herbs to get their indoor start.
