Seed Starting Chart: Best Times To Start Your Seeds
Ready to get growing? Our handy chart will help you figure out when and where to start your seeds.
Ready to start that spring garden but not sure when you should start your seeds? We can help. Our seed starting chart helps you determine when and where to start your seeds. Some seeds should be started indoors, while others can be directly sown outside. Refer to our Average Frost Dates to determine your last spring frost.
Your seed packets will have most of the information you need, but here are our recommendations:

How much does the seed starting timeline change (in general) if the seedlings are to be transferred to a non-heated greenhouse (in grow bags) as opposed to in the garden?
Should seedbeds for above ground and root crops follow the same days as planting those crops? Or can any crops be started on days good for seedbeds?
We consider a seedbed to be a bed of cultivated soil prepared for seeds or seedlings that will be transplanted, regardless of if whether they will ultimately be above ground or root crops. If you are direct sowing (planting where you want the plant to grow), then plant by the appropriate best day for that type of crop.
I use a separate Google calendar from my personal calendar. Put in my dates there and set alerts, for the following or preceding weekend, to remind myself to get in the garden!
Is there a link to the place where I can put in my frost dates for my zone along, with the veggies and medicinal herbs I’m planting, to populate and remind me when to seed, transplant and harvest? Any suggestions?
