Description
Keep in mind that Zinnias are native to Mexico, where they have become accustomed to long, hot summers. They are classed as tender annuals & can be directly sown into the garden after all danger of frost is over & daytime temps are at least 50F & above. in cooler climates, start seeds indoors 4 to 6 weeks before your area's average last-frost date. Harden off the plants by vacationing trays outside for a few hours per day before planting them in your garden. WHEN & WHERE TO PLANT ZINNIAS Zinnias are best started directly outdoors in locations where spring warms up early. Turn over the soil in the area you want to plant your zinnias & work in 2 or 3 inches of compost or peat moss to help improve soil fertility & drainage. Plant the seeds only about ¼" - ½" deep & you should see seedlings sprout in four to seven days. Once the seedlings reach about 3" tall, thin them to maximize air circulation, & prevent powdery mildew. The dwarf varieties, reaching a height of 1 to 1 ½ feet, should be planted or thinned to about 9" apart, while the taller 3-feet varieties should be spaced about 1 foot apart. STARTING ZINNIA INDOORS If starting your zinnias indoors, fill up your pots with organic potting mix. Saturate the potting mix with water & then place two zinnia seeds into each planting cell or pot. Press into the soil for good seed-to-soil contact & then cover with approximately ½" of the potting mix. Place your zinnias in an area that will receive plenty of warmth (65-70F) & light. Keep your zinnia seeds moistened, checking on them every day or two. Expect to see germination in about 7 to 10 days. Once your seedlings reach about 2 ½ - 3" tall, they are ready to be transplanted outdoors. Zinnia Isabellina Heirloom Flower Seed 50
