Zinnia seeds are often recommended for beginners, this undemanding annual germinating relatively easily when sown directly into the garden or when started in individual peat or growing pots. Sowing indoors will, of course, result in earlier blossoms, and may be your best option if you live where the growing season is short. The soil temperature, when germinating indoors or out, should be consistently between 70 and 80°F. Zinnias need some light in order to germinate, so only cover them lightly, with 1/4-inch light garden soil or vermiculite, and then water gently but thoroughly, being careful not to dislodge the seeds, especially during subsequent watering. Once they’ve sprouted, normally in 5 to 10 days, you will want to thin as recommended to the strongest plants. Give them their first feeding when they are 4 to 5-inches tall, at about 1/4 the recommended strength, increasing to full strength over the season on a monthly basis. Deadhead often, keeping your vases filled, but more importantly, ensuring more and more blossoms. Your zinnias will grow best when getting about an inch of water per week, just like your lawn.
