I came across Sprout Robot in the past week, you simply create an account and provide your zip code and it will give you a complete calendar of planting dates as well as follow ups when to expect sprouts to form, when to bring out, harvest etc.
When a new event is coming up you will get an email similar to the one below letting you know what is new to plant that week.
When you connect to the site you then can “Check-In” and check off the tasks you have completed which get updated with next event for that plant.
They also have an option where they will even send out organic seeds just in time for planting in your area starting at $19.99 a year, though personally I have plenty of seeds saved for at a couple of years in my refrigerator.
It seems like every year there is something I decide I want to grow in my garden only to discover I am a couple months late to get started. In the past season this was brussel sprouts, I had grand visions of growing them this winter only to discover I should have started the seeds back in March…
I got a great idea when I was planning this years garden in GrowVeg where I simply created a plot and just dropped in each vegetable that I typically eat and enjoy regardless is I have grown them in the past or plan to in the future.
This way when the time comes when I should be planting these I will see this on the chart I printed out and get a reminder email in my mailbox from GrowVeg I can make this impulse decision to get seeds and start these plants at a time where I can still be successful.
Just by doing this exercise I have decided to consider fennel, Jerusalem artichoke, parsnips, and sweet potatoes. Sure many of these may result in utter failures in my cold damp area but at least I can make sure I can start at the right time to give them a fighting chance.
