HOW TO GROW TOMATOES {PART 1: PLANTING SEED INDOORS}
My ultimate favorite in the garden... I drool at the thought of a fresh tomato sandwich, and believe me - the 60 jars of salsa I get from my canning usually doesn't last till the next season! I used to buy my $8 tomato plants at the greenhouse until I realized how easy and cost effective (and relaxing) it was to plant and start the seed on my own! So now, for $3 I sow about 30 plants! The variety of tomato seeds is endless - I usually purchase 1 package of beefsteak, 1 package heirloom and 1 package of a tiny tomato variety (Dani's favorite for picking) - This year I did Italian Heirloom - 1 lb fruit great for slicing (my go-to best), Mountain Princess - reliable and produces well, Hendersons Winsall - large beefsteak great for canning, and Cherise Orange - tiny orange tomato, produces lots, great for salads.
STEP 1:
Get Your Supplies
STEP 1:

- Potting Mix - can be bought and any home/garden centre. I get the mix that mentions it's great for seed flats. They usually contain a soil/peet mix with mulch (for nutrients).
- Seed Flat - these usually come with potting pucks that you absorb with water and use as soil - I usually don't use those and just use my own potting mix. The flat will contain cells which make planting small seed easy. It also comes with a plastic dome to imitate a greenhouse.
- Seed - I buy my seed at the end of February so I have enough time to prepare my planting schedule. Great seed can be found at your local greenhouse or online. I purchase mine online at www.heritageharvestseed.com
- Pencil - will be used for creating seed wells for sowing.
STEP 2:
Prepare your Seed Flat
- Pour soil in your seed flat tray till the top line. I find that soil levels often go down with watering.
STEP 3:
Moisten the Soil
- Damp soil is key to your seed germinating. You want to make sure the soil is wet, not swampy, but not dry either. I use a watering can and do a quick sprinkle and give the soil a couple minutes to absorb.
Make Your Seed Wells & Sow
- With a pencil poke holes approx 1/4" deep into each cell. I use my pencil as guidance (where the sharpened tip turns to pencil).
- Place 1 seed per hole
- Gently cover with loose soil. Even soil out without packing it down.
STEP 6:
Label
- Label the flat with what was planted (and where) - sometimes I also include the date I planted the seed. This time I just cut out the label from the seed packet and taped it to the flat.
STEP 7:
Finishing Touches
- I usually add a sprinkle of water on top when the seeds have been sown.
- Place the plastic dome on top of the flat
- Find a place in front of a window where the flat will receive lots of sunlight, away from a draft or cool air. Seeds germinate best with a greenhouse effect (lots of sun and moderate heat).
After a day or so you'll notice humidity building in your seed flat. That moisture will provide your germinating seed with the water it needs to grow - so no watering necessary. Ensure the dome stays on at all times to keep humidity in. After about a week you'll notice the first signs of what will be very delicious produce! When the plants have grown about 1" tall - I remove the dome and water when necessary to keep the soil moist (approx every 3 days). When the plants get approx 3" tall I transplant to a bigger cup before moving to the garden (Part 2 will be on transplanting).
There you go - you did it! And in a few short months you'll be adding these plants to your beautiful veggie garden! Enjoy!
