This is a sweet little Australian video (6:36) without much visual interest (locked off camera showing Greg planting seeds in seed trays) but it contains some interesting information about planting tomato seeds “chemical free.”
Greg places seed raising mix in trays, but he says you can also plant them in little pots. As a horse is heard clopping by, Greg informs us that he is planting Rama tomatoes this year. At the same time he is planting some marigold seeds. These plants, along with garlic and basil, he will plant among the tomato plants to ward of nematodes (soil borne germs that are fatal to tomatoes) and also insects.
As Greg’s dog Jenny starts yapping in the background, Greg reminds us that it is best to have clean hands when working with seeds and seed raising mix. Once the seeds are nicely planted, you spray them thoroughly with water from a plastic spray bottle and place them in warm part of the house. In 5 or 6 weeks the seedlings will be ready for planting.
