Snapdragon Potomac Early White is a hybrid line flower developed for professional cut-flower production. It is specifically bred to produce high-quality, exceptionally tall stems with an excellent taper during the moderate light and temperature conditions of spring and autumn. These plants reach a mature height of 39 to 60 inches and feature clear white blooms on sturdy, upright spikes.
Potomac Early White Selling Tips
Snapdragon Potomac Early White is a strong resale choice for growers serving cut-flower and landscape markets. Its tall, upright stems and bright pink blooms make it easy to promote for spring and autumn bouquets, floral work, garden centers, and landscape borders.
General Growing Tips For Your Seedling Tray
You should keep your media pH between 5.5 and 6.0 and use a feed program of about 100 to 175 ppm Nitrogen . Be careful with your fertilizer choice, though, as snapdragons are very sensitive to high salts and high ammonium levels, which can lead to soft, leafy growth.
Pinching
Don't pinch these plants! They are bred to be single-stemmed "line flowers," and pinching will only delay your crop and result in shorter stems
Spacing
We recommend a professional planting density of 10 to 12 plants per square foot to ensure proper airflow and light penetration.
Pests
Regularly scout for aphids, thrips, spider mites, mealybugs, and whiteflies. Thrips are a major concern as they can transmit serious viral infections like TSWV and INSV.
Disease
Stay alert for botrytis, rust, powdery mildew, downy mildew, and various root or stem rots like Pythium and Rhizoctonia. Maintaining excellent airflow and ensuring plants dry before nightfall are your best defenses against disease.
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.
