Magellan Yellow Zinnia Flower Seeds

Magellan Yellow Zinnia Flower Seeds

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. Zinnias have a delicate root system; therefore don’t respond well to transplanting. If starting indoors, ensure you use transplantable pots that will allow you to transplant without disturbing the roots. The soil should be well-worked, free of clumps and the seeds sown after all danger of frost has passed. 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. Covering the seed bed with clear plastic or glass until the seeds sprout will ensure a consistently moist atmosphere for germination and will hold the heat during cooler nighttime temperatures. Once they’ve sprouted, normally in 5 to 10 days, remove the cover and keep the soil evenly moist, but not wet. Depending upon the variety, you will want to thin as recommended to the strongest plants, being careful not to disturb the tender roots of the neighboring seedlings. You can, instead, simply cut the unwanted seedlings off at soil level. 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.
