Seed-starting season is in full swing in these parts. I’ve been getting loads of questions about it via email and figured it was time to put together a seed-starting recap here on the site.
I started my own tomato, pepper, and tomatillo seeds this weekend and put in orders with two seed companies to complete my 2007 Scary Mega Plant List. This last order totalled about 25 packs of seeds coming in at roughly $75 US. When you take into account that this does not include the transplants I will get in early June… well now you know why it’s the “Scary Mega Plant List.” I don’t want to scare anyone off and give the impression that gardening has to be this expensive. I do not fall into the norm since I consider my garden to be an experiment and a BIG, BIG part of my job. I grow as many new varieties as possible every year in search of beautiful, drought tolerant, delicious, and container-suitable plants to share with you. Most people do not grow 5 different pea varieties on their urban rooftop!
First I’ll show you my plan for this year. In my last post I gave a review of the Windowsill Seed Starter. What I did not mention is that I managed to snag the larger version at a garage sale for $3! The larger version is much more reliable with larger pockets that will keep your seedlings healthy for a more reasonable length of time — the downside being that it will not fit on a windowsill.
Because I am short on space I have a crazy plan based on last year’s experiment in which I moved my final repotted transplants to a window in the hallway of our apartment building to live out their final days before heading outside. By the time they were large enough to repot, the hallway was warm enough to accomodate them. It also made a nice transition from cushy to slightly-less-cushy. I’m pretending that was one stage in the hardening-off process. When faced with obstacles it helps to wrap them in a thin veneer of positivity.
Here you can see the little tags I made using toothpicks, sticker paper, and indelible ink. The other major downside to this kit is that it is too tall to work with my beloved heating mat. It’s been unseasonably warm so I think I’ll be fine without it.
These are the ratios I prefer. If you don’t need a huge batch you can use this as a basis for choosing a store-bought seed-starting mix. Always read the label and look for an ingredients list. Most popular brands have chemical fertilizers added that are both unneccesary, but will defeat the purpose of growing organically. Instead, buy a basic mix and add in your own organic materials. I suggest adding a touch of vermicompost and watering your plants with a diluted sea-kelp mix. To be clear, seeds do not require any fertilizers until they produce their first set of “true leaves”. In basic terms this means the second set of leaves you will see. The first leaves that appear are called “seed leaves” and feed the seedling until the first “true leaves” appear.
- 1 part peat or coir (Coir is a sustainable peat substitute made from coconut husks. Peat is mined from marshland, destroying natural habitats. When you can, use coir.)
- 1 part perlite (popped volcanic ash that creates good drainage.)
- 1 part vermiculite (water absorbing material made from the mineral mica)
