I tried several different methods of seed starting over the last 8 years, before I settled on this one. Good seeds plus good seed mix means you can’t go wrong, unless slugs are involved.
My best choice ever (seed startingwise) was to try a new product from my favorite organic fertilizer company, Espoma.
Their Espoma Seed Starting Mix is part of what made this my best garden year ever! Another part was the superior seeds I purchased from Baker Creek Heirloom Seeds.
I had some old container trays that I recycled & brought home from Cofer’s when I worked there last year. They have drainage holes and are perfect for starting seeds, but any container with drainage holes can be used.
I transplanted from the seed trays into recycled 4 pack trays on Sept 4th. I mix 1/2 organic mushroom compost, 1/2 organic topsoil, & add Espoma Plant Tone. Mix these together well, and transplant seedlings. They stay in that soil mix until they are ready for transplanting into the raised beds.

Gradually move into more sun
I started the first round of seeds in mid August, but had a slugtastrope & had to plant more seeds. I now move the baby seedling trays onto the deck at night to avoid slugs. This fall, I planted Broccoli, Kale, Cabbage, Brussels Sprouts, Collards & Cauliflower in seed trays.
Some types of veggie seeds achieve best results by direct sowing them into the place they will grow until harvest. This past week, I direct sowed carrots & radishes.

New posts coming soon about the expanded garden bed construction, summer harvests & more fall planting details. These babies are almost ready to go into the ground! I will likely plant them around end of September.
Happy Gardening!
