The quick answer is, if you live in my area of Connecticut, usually early to mid-March for some plants. But each type of warm season vegetable has a bit of different timing as to when to sow the seeds indoors ahead of the planting season. And the best way to double-check those timings is by looking at the seed packets and/or following specific seed sowing guides.
For beginners, it may feel overwhelming to do all the planning homework on when you should start start sowing your seeds for your favorite tomato or hot pepper plants. But knowing when to start is key. Many people start by buying packets without really knowing the timing, and that is sometimes a mistake if the seeds are not ordered on time and/or if they don’t realize the growing requirements of the plant itself.
If you start sowing seeds indoors too early, things get messy. The plant will be too large and root bound before you are able to safely plant it outdoors (after frost in May). If you start too late, you are basically not giving the plant enough time to produce fruit (and that would be a major disappointment).
I think what is even more important than knowing when to sow the seeds indoors, is when to get your supplies ready.
Last year, with the onset of COVID, people discovered many seed sources were so bombarded with orders that the seed sources were sold out or delayed due to shipping issues associated with COVID. This may result in a major problem, you definitely need the seeds on time to start them on time.
This issue, however, actually allowed me to sell seed packets and seed sowing kits I had already assembled for an upcoming farmers market talk in early spring last year, which was also cancelled due to COVID.
I quickly let everyone know I had them available and people came by to pick them up from me via zero-contact porch pick-ups. The whole process was a fun adventure for me and people told me they enjoyed not only my seed selections but my instructions and guides.
In my opinion, you should really start to think about the whole preparation process right now in late January or at least by early February.
Why? Because you need several items to sow your seeds: seedling trays, seedling mix, and a set-up (place in the home with sufficient light) or you may even need to purchase grow lights to hang over your seedling trays.
I’ve created 3 guides which I included in the packages for anyone who buys seed packets from me or seed sowing kits. Each guide is a bit different.
One guide is a chart which shows when to sow the seed, how many weeks it will take for the plants to be ready, when to plant it outdoors safely. It is a nice one-pager for reference.
Another chart I provide is a new one I created this year, which is also a one-pager and it shows “the weeks before frost” specifically for the seeds I am offering this season. If you wish to learn which seeds are available, just email or text me (see below information) or visit http://www.WORKSHOPSCT.com.
In other words, each type of plant must be started a number of weeks before your last spring frost date. My “weeks before” chart lists shows the 10 week mark, 6-8 week mark, 4-6 week, 2-4 week, etc. For example, some hot peppers are started 10 weeks before, which is early March (when to sow).
Lastly, a chart I provided last year was an actual “calendar month by month.” It is similar to wall calendars. I’m still thinking about if I should do this one again, or just use the new “weeks before chart.”
But the general point is – all of this information took lots of time for me to assemble for you to make it easier for you to do your sowing.
My seeds are primarily focused on warm season vegetables such as the tomatoes, cherry tomatoes, hot peppers. I hand-pick new varieties each year based on their uniqueness, taste, and if they are heirloom, etc. I also pick out parsleys, basils (3 types), and chives, etc.
I also created a chart for young kids which is a way to record the progress of the seeds. I’m liking this idea more and more to include with anyone who buys seeds and/or seed starting kits from me for their kids to use as additional education tools.
Another reason why planning is so important is because plants growing indoors from seed need to be hardened off before you put them into container gardens or patio pots (or gardens) after frost in the spring. This process occurs one to two weeks before you plant them outdoors permanently. It is a process to acclimate the seedlings to the outdoor environment.
Once of the best parts of offering the seeds and sowing kits is that I hear feedback from buyers of how wonderful their harvest is – and yes, sometimes there is feedback of issues (the dreaded tomato hornworm). But that is all part of the learning process.
A couple of my buyers have children. I absolutely adored when one mom sent me a photo of her daughter holding a huge Upstate Oxheart tomato next to her face. These tomatoes plants grow huge tomatoes, and it was super fun for them. And they sent me of a photo of a tomato on a kitchen scale weighing 2 lbs. too. They were thrilled, and it still brings a big smile to my face knowing my help got them into growing and enjoying their new hobby.
The more I hear of the kids with their parents or their grandparents (the cool ones! LOL), the happier I am that they experienced the sowing process together. This year, I picked a really compact and tiny tomato variety that I think will be much fun for kids (and adults).
But it all starts when you decide to give it a go. Here is a tip sheet if you are considering it for this season.
