How many packages of flower seeds (Profusion Zinnias) will I need for an area 6 feet in diameter and how soon can I plant the seeds? |
These plants grow to be about two feet across, so you will want to grow them about two feet apart, possibly a bit closer for quicker coverage. One packet should be enough for the approximately seven to ten plants you will need. Zinnias can be started indoors about 6 to 8 weeks before your last expected frost date or after danger of frost outdoors. |
