A free seed starting calculator for when to start seeds indoors, a calculator to learn when to set out your seedlings, and a seed quantity calculator to determine how much seed you need for your garden are some of the free online gardening tools at the Johnny’s Selected Seeds website. Every gardener will find these charts and calculators incredibly useful, whether you’re planting one garden bed or a field.
Seed Quantity Calculator
Whether you’re a farmer or a novice home gardener, this calculator will tell you how many transplants or seeds to plant in each row. You choose the crop and the length of your row, click on “calculate” and voila! The correct number of seeds or transplants you’ll require appears. It also has a second calculator for larger plots and multiple rows. See the seed quantity calculator.

I absolutely love this one. At the top of the calculator, enter the potential last frost date for your hardiness zone – in my case here in zone 6, it’s May 15. The calculator then compiles the indoor seed starting date for the most common vegetables, flowers and fruits, and the “safe” date to set those seedlings in your garden. See the seed starting calculator by date. If you don’t know your last frost date, check our last frost date guide.
Johnny’s Seeds has also added how-to videos, a Fall planting calculator, and a few other things you might find useful.

I just noticed on Johnnys site that the seed starting calculator is having some issues- I can’t view/print it as the left hand side is covered up by their shopping menu. I wonder why they don’t offer it as a downloadable spreadsheet like they do their other tools?
This really answered my problem, thank you!
What seeds start well in 200 cell plug trays please
Debra: The tray you use has little to do with the type of seeds you start (some will argue this but bear with me). 200 cells is a big tray and you should be using different trays for each crop, otherwise it will be difficult to keep track of what type of seed is in each. But to your point, nearly any vegetable, herb or flower will do just fine.
Speaking of seeds and mild weather, I just came in from pulling dried pole beans off the plants. Never got around to doing it at the end of fall but really enjoyed this particular bean. I got the seeds at the New York Botanical Gardens. They are from Italy and have a great taste so I want to try and replant to see what happens. I replanted them last year and they turned out great. But this year since they’ve weather half the winter, albeit a mild one, the seeds I collected are smaller than what I usually see and some look wrinkly and have some white. on them. Do you think these seeds will successfully produce?
Lucia:
Since the seeds were outdoors in the pods until now, I would think they’d be fine. There’s a chance that the “white” on them is a fungus, but that’s impossible for me to determine without a photograph. I would just plant them and see how they do – beans are incredibly hardy and usually thrive under the most extreme circumstances.
What kind of bean is it?
