You’ve got the seeds, you’ve got the enthusiasm and if you’re like most gardeners, you’ve also got about 47 open tabs with conflicting advice about when to start everything.
Close those tabs. This weekend, I spent a lot of time with my seeds and my nemesis—ChatGPT—commanding it to come up with the perfect seed-starting schedule for me. And now it can create a perfect seed starting schedule for you.

With AI
Instead of squinting at the back of a seed packet, doing questionable math, and then hoping for the best I'm going to show you how to make a completely customized seed starting schedule instantly by using one simple AI command.
You'll be a seed starting star - the accolades from friends and family will be an embarrassment.
Artificial intelligence is only as helpful as the commands you give it. I played around over the weekend refining my commands until I got an easy to read seed starting schedule with all the information I wanted for my seeds.
Here's the beauty.
Seed Starting Schedules
If you're only starting 3 or 4 different things it's not a big deal. Your brain is probably still agile enough to keep a few planting days straight and the plants alive.
But once you delve into needing BOTH hands to count how many types of seeds you're starting then you need to plan.
You need a schedule because if you’ve ever tried seeding multiple seeds on multiple planting dates over multiple months without any plan, you know how quickly things can death spiral.
I Compared It Against My Own Experience
After AI created the schedule, I crossed referenced it with my own hand written schedules from the past few years. I *know* the best time for me to start beets, based on my trial and error experience over the years, is the middle of March.
The artificial intelligence scheduled recommended I plant beets on March 13.
Perfect.
How It Works (and YES it's Free)
The schedule is tailored specifically to you. It takes into account your USDA growing zone (or equivalent), your last frost date, and factors in germination times for any and all plants you want to grow from seed.

We'll email you this post, so you can refer to it later.
🌱 You’ll never start too early or too late—which means stronger plants and better yields.
🌡 You’ll know at a glance if your seed needs a heating pad to start it.
💡 You won’t have to keep Googling “Do onions need light to germinate?” (Spoiler: They do.)
📆 Everything is sorted by start date, making it incredibly easy to follow.
Get Your Own Custom Seed-Starting Schedule
You don’t have to wing it this year. You don’t even have to make a spreadsheet. Just tell ChatGPT your zone, last frost date, and the plants you’re growing, and it will generate a perfectly timed seed-starting schedule for you.
Use this exact command to get yours:
Copy and paste the command below into ChatGPT. Then replace anything inside of brackets with YOUR information.
"Create a customized seed-starting schedule for me based on my USDA hardiness zone and the plants I want to grow. I am in USDA Zone [X] with a last frost date of [Month, Day]. Please generate a detailed schedule including: Plant name, Start Date, Method (Indoor/Direct Sow), Planting Out Date, Days to Germination, Optimal Temperature (both °C and °F), and Light Requirement (Light or Dark for germination). My plant list includes: [List your plants here]. Make sure the schedule is formatted concisely and sorted by start date."

It will analyze for a moment and then create something like this ...
Double-Checking ChatGPT’s Answers
I always like to double-check any information I get from ChatGPT. After it gives me an answer, I follow up with this simple command:
"Double-check that information to confirm it's accurate."
If you’d like, you can copy and paste your schedule into an email to yourself or you can download the information and put it into whatever your favourite spreadsheet is.
I used Google Sheets to create a schedule that will print on one page of paper.
I had to mess around with the margins to get it to fit on a single letter size sheet of paper.
Use your schedule as a guide and take notes this year if things don't work out. But this will be an excellent starting point and guideline for your plantings for years to come.
I think. I mean, this is gardening and all hell could break loose at any moment.
p.s. The shelf over my right shoulder holds some of my favourite books of all time.
Very cool, but you don’t have to use your nemesis. Do a search for “Seedtime” and they have a fantastic free garden calendar. It’s also an app, but for now the site has more functionality. It’s also more than a calendar. I have no affiliation, just found it recently and squealed. Then had no serious gardening friends to tell till now. It’s USA based, but hope it works for Canada too.
:-)
Thanks. Good excuse for me to start ChatGPT.
Yes. Even before reading article I scoped out the books. (And your hidden storage units. Which have always fascinated me).
I like your hair longer like this. Shows off your pretty hair.
Awesome, thank you. Btw your hair looks great!
OF course I was checking out your books, counting how many I’ve read too! This is a Godsend gardening tool and can’t wait to spend the day tomorrow working up our plan. Thank you! Now, if I can just figure out how/what ChatGpt works! Boycotting spending anything tomorrow, so this is the perfect antidote.
Isn’t it also about time for a 2025 Book/show recommendations speaking of a full bookcase?
