Potomac Red Selling Tips
Sell Snapdragon Potomac Red to cut-flower enthusiasts and designers who need a powerful vertical element for their summer gardens or professional bouquets. This variety is a summer powerhouse that produces its strongest, longest stems during the peak light and heat of the season.
General Growing Tips For Your Seedling Tray
Maintain a media pH between 5.5 and 6.0 . As a Group 4 series, these plants require temperatures consistently greater than 60°F. Potomac Red grows best in full sun with bright light, steady airflow, and a well-drained growing environment.
Pinching
We do not recommend pinching Snapdragon Potomac Red, Leaving plants unpinched helps encourage longer primary stems and larger flower spikes.
Spacing
We recommend a planting density of 10 to 12 plants per square foot to ensure every plant gets enough light penetration and airflow.
Pests
Regularly scout your crop for common pests like aphids, thrips, and spider mites.
Disease
For diseases, stay alert for Botrytis, rust, powdery mildew, and Pythium root rot. To help prevent stem rot avoid burying the stems below the media surface.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
