This is how I do:
1. Take a Tomato, make sure that it is nice and red and mature.
2. Slice it in 1,5 cm thick slices.
3. Put some soil in a pot, bucket or plant starter. I use my Homemade Self Watering Seed Starters. Place the Tomato Slice on the soil.
4. Cover with about 1 cm of soil.
5. Put some plastic over the pot to create a good climate for the seeds to sprout.
When the seeds have started to sprout you have two options:
- If you want to have one or two strong plants: Cut all the sprouts of except of one or two
-. If you want several plants: Carefully separate the sprouts in different pots
I will keep you posted here. To have more guidance through all the steps, see my post from last year: Growing Cherry Tomatoes from Tomato Slices
