I know, it can be a bit confusing when first starting a garden of any type. The most common questions I receive?

  1. When do I start my plants from seed?
  2. What seeds should I start now?
  3. How do I start a plant from seed?
  4. When is it safe to transplant my seedlings into the garden?

So let’s break it down. It’s really not difficult, especially when you create and use my seed starting schedule.


A seed starting schedule or chart is a journal or record. A plan that can be made far in advance of planting time.

When I first began my gardening journey, I cannot tell you how many times I’d forgotten to sow a seed, & missed the date of when it should have been sown.

That translates into missed opportunity for growing my own from seed in a timely manner, having access to more unique plants, & saving money from having to purchase plants at the local nursery!

Starting your own plants from seed offers joy in the height of colder months. After all there is nothing better than seeing new green growth in the height of winter. And it is easy to do.

Creating this schedule also ensure’s that your seedlings will not be too young come transplanting time or too spindly or “leggy” by the time they need to be moved. It’s a way to create the “just right” moment for each plant.

As I always say, you may think you will remember come planting time what you grew last year, but I guarantee you won’t. Especially when growing large numbers of plantings.


If just starting out, planning is key to a successful gardening year. First starting with a few easy reads you can find right here will have you on the right path to success.

Be sure to begin at the beginning with “Starting A Vegetable Garden From Scratch” and then take a look at “Seed Starting 101” for a complete tutorial on how to start your seeds indoors.

These tutorials will answer many questions in regard to starting plants from seed and planning out the garden.


A good seed starting schedule will offer you a lot of information when planning out the garden & for looking at past gardens. That being said, keep your seed starting schedule pages in a garden binder year to year for easy referral!

Creating your seed starting schedule becomes easier to do year-to-year, as most times you will be growing the same varieties and will only need to make minor adjustments from any notations you may have made the previous year.

Any garden begins with a seed. Learning about what you will be growing from seed begins with “Reading & Understanding Seed Packets”. Most of the information you will need to use when creating your seed starting schedule can be found right on the jacket.

At the minimum this schedule should give you a space for listing the variety, sowing date, and transplanting date. The below should be used only as an example . I also find the hardening off date to be useful. More on that topic can be found below.

To determine the date of last frost in your neck of the woods is made easy using this calculator. It’s also important that you know your gardening zone when choosing seed varieties. This information helps when creating & planning your garden and developing your seed starting schedule.

Write in your date of last expected frost at the top of the seed starting schedule once you have it. Please note, this is an expected date of last frost. Obviously, weather will change year-to-year, location to location, and even source from source (who you’ve gotten your dates from). Take an average and go from there.


This is an obvious one. I typically will write the variety name (Cherokee Purple) or cultivar and not just the generic type of plant name (ex. tomato), as I grow a lot of each type of plant. Knowing the cultivar will help in future decisions when planning your growing season.

For instance, there have been several cultivar of tomato’s that I just don’t bother with any longer due to their lack of disease resistance in my growing area. Why grow something when it doesn’t do well?

By keeping track of individual cultivar names, I can then easily delete and add from my seed starting schedule as needed.


This can be difficult to determine when first planning your garden. After all, how do you determine how much and what you should grow when you’ve never done it?

“How To Grow What You Eat” should give you pointers in regard to answering just those questions & more!

Once you’ve made your decision(s), write in the number of seeds sown in the seed starting schedule in the “#” column.


When it comes to seed packets, if you have read “How To Read & Understand Seed Packets” you know that just about every company will have a differenct approach to listing vital growing information.

Some are very thorough and direct, and other’s, well, crytpic at best.

The above seed packet is an example of just that. Giving limited information, but yet all the information you will need for creating your seed starting schedule. When to sow the seeds, & when to transplant the seedlings into the garden space are all listed.

For example, this organic Sweet Basil packet tells me that I need to plant or sow the seeds 3 weeks before my expected last frost date. My last frost date is May 15. Counting backwards from May 15 by 3 weeks on a calendar will give me an approximate sow date of April 24. I would then add this information to my schedule.

NOTE: I find it helpful to round the dates to the nearest day of your choice. So if your planting day will be a Saturday, round all the dates to the nearest Saturday. So much more easier to keep track of come planting time!


There are a few general guidelines when determining when you can transplant your seedlings outside. First and foremost, the obvious. Refer to your gardening zone and your last frost date.

Check out our Microgreens at True Leaf Market

When it comes to filling in the information on your seed starting chart, follow the packet instructions. This package tells me that I can expect to either direct sow/plant the seeds or transplant my seedlings sown indoors “after danger of frost”. My last expected frost date is May 15th. Weather depending, I can transplant these seedlings into the garden space any time on or after that approximate date.

I fill in my expected date when planning the schedule out, and then add the actual date of transplanting once the seedlings have been relocated into the garden space.


To “harden” seedlings is to simply acclimate that plant to the outside. It’s the process of hardening off the plants that will allow them to gradually adjust to more intense sunlight exposures, fluctuating temperatures of day to night, and watering schedules.

Begin the hardening off process approximately 2 weeks prior to your transplanting date, weather permitting. Keep close watch on dipping temperatures and freeze warnings, bringing those plants into shelter if need be.

Herbalist Courses for all levels

To begin the process, place your seedlings in a sheltered area for several hours and increase slowly overtime the exposure to direct sun & wind conditions. Eventually, allowing them to remain overnight.


Hopefully by utilizing your seed starting schedule this will not be in question any longer, just sayin’ 😉

By reading the seed packets, filling in the appropriate information into the seed starting schedule, you will have efficiently outlined your growing season, when to sow, harden off, and transplant.

Here are a few plant varieties that are commonly grown with approximate sowing information based on your last frost date.

  • 10 to 12 WEEKS – Some herbs, celery, parsley, kohlrabi, celery & onions
  • 8 to 10 WEEKS – Lettuce, spinach, chives, onions, peppers, asparagus, leeks & some herbs
  • 6 to 8 WEEKS – Peppers, tomatoes, broccoli, cauliflower, eggplant, and cabbage
  • 4 to 6 WEEKS – Basil, fennel, cucumbers, melons, winter squash

With a little planning and forethought, by creating a seed starting schedule, you will then be prepared each week for what to sow & start. This is one planner I wish I had when I first began, and is now one that I couldn’t do without.

This is great info and a great resource. What about areas that don’t frost?

Suzan Ferreira February 9, 2021 - 3:55 pm

Hi Stacey!
Great question. The good news? You have many more options and times that you can plant! I recommend looking at your local extension office for recommended planting times. When starting from seed you can still utilize the packet information which shows germination and days to mature and count back to when you are wanting to add that plant to your garden area.

Hope that helps!


Stacey February 7, 2021 - 5:06 am

This is such an important post! I just sat down with a notebook and did the same thing a couple weeks ago. I know a lot of people are just starting to garden this year, though, and this has such wonderful information. I’m going to be sharing in my circles 🙂

Never thought to make a schedule to start the seeds! Great idea!

I truly love to garden! However I don’t have a very large vegetable garden space. Most of mine is devoted to herbs and flowers. I’d love to have a small greenhouse to start seeds in. Might have to see what I can arrange in my backyard.

This is perfect, this has been on my to do list. This will make it so much easier to figure things out!

Great, thorough post! You have a short growing season, too. I was surprised, moving from southern Ohio (where I could put out my tomatoes on St. Patrick’s Day!) to New Mexico, where the altitude forces a short growing season; our last frost date is May 6!
Gardening here is not for the faint of heart!

Sandi Barrett January 19, 2021 - 12:52 pm

Lots of great info here. I always seem to have a vacation right in the middle of seedling time. Either plant and pray, hire a plant waterer, or delay planting – never sure which way to go.

Chelsea January 19, 2021 - 7:15 am

This is great. I haven’t had much luck with starting from seed. But I want to do it more because I haven’t tried it often, truthfully. I mainly start with baby plantings and go from there. This is great info. Thanks!

Barbara January 19, 2021 - 4:32 am

You are so organized and talented!

Tricia Snow January 19, 2021 - 3:35 am

I need this information. I am terrible with the organization. Thanks!

Tiffany January 19, 2021 - 1:29 am

Just thinking about planting a garden makes me feel like spring is almost here (even though I spent the weekend shoveling and currently wrapped in a blanket!

The last several years we have purchased seedlings, but I think starting our own indoors would be a fun, cheery thing to carry us through the rest of winter. Thanks for the scheduling idea and great post.
