This seed starting planner from aQuickStudy is just the thing to help figure out when to plant those green beans.
Dabble with planting with this garden dibble from woodenapple.
We planted mostly vegetables, but I couldn't resist starting some black eyed susans. Thebearfootshaman has black eyed susan seeds.
I adore these antique terra cotta garden pots from solsticehome.
MakeScentsWithNature has these wooden paper pot makers - I recently bought one from their shop and I love it. It's even easier to use than I thought it would be. Can't wait to make your own pots? RushofWings has newspaper pots already made for you.
You could also start your seeds in a sweet little vintage coffee cup from ARareThread. Don't forget to water your seeds regularly. It's very important. Remind yourself with this Water Me garden marker from monkeysalwayslook.
Once you've transplanted your plants outside, you'll need garden markers to keep track of which plant is which. MakeThyme has these copper garden markers that will do the trick.
