Coach Your Customer Plant in a location that receives at least six hours of full sun to ensure the most fragrant and sturdy flowering spikes. Maintain consistent soil moisture, especially during the first few weeks, to help the root system establish properly in the cool spring soil. These are cool-season specialists that provide beautiful color and scent until the high heat of mid-summer arrives . Since these grow on a single, sturdy spike, never pinch the plant, as this will destroy the primary flower .
General Growing Tips For Your Seedling Tray
For professional production, plant one rooted liner per 4-inch container using a well-drained media. Maintain a media pH between 5.8 and 6.5 and provide a balanced constant fertilizer feed of 175 to 225 ppm Nitrogen . As a cool-weather crop, Avalanche should be finished with daytime temperatures of 55 to 65°F and night temperatures of 50 to 60°F to ensure high quality and prevent flower bud drop . This variety typically finishes from transplant to sale in about 10 to 12 weeks and requires high light levels throughout production . Watch for common pests like aphids and thrips, as well as diseases including botrytis and powdery mildew .
Pinching
These plants are specifically bred to be "line" flowers, meaning they put all their energy into producing one magnificent, high-quality central flowering spike . If you were to pinch them, you'd actually be destroying that primary flower head, which is exactly what your customers are looking for . For the best results, just let them grow straight up on that single, sturdy stem .
Spacing
We recommend spacing your 4-inch containers 6 to 7 inches apart on center in the greenhouse.
Pests
Keep a close eye on your crop for common insects like aphids and thrips that can impact stem quality and flower development . Scout regularly for pests and implement an Integrated Pest Management plan in your greenhouse to prevent insects from damaging your crops .
Disease
High humidity and cool temperatures can trigger several foliar pathogens in Matthiola such as Botrytis and powdery mildew, making environmental control your first line of defense . Most of these issues are associated with wet foliage or stagnant air in the greenhouse .
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.
