Mammoth Rose Pink Selling Tips
Sell Mammoth Rose Pink to customers looking for premium fragrance and dramatic vertical interest for their spring gardens. The Mammoth series is highly valued because it’s less sensitive to day length, which means earlier harvests and longer, sturdier stems for your customers. Home gardeners will love the look of these rose-colored vines climbing up a garden obelisk, while florists will prize the long stems and sweet scent for bridal bouquets [6, context]. Remind your customers that frequent cutting actually encourages more blooms, giving them weeks of fragrant indoor displays.
Coach Your Customer Plant in a sunny spot with rich soil as soon as the ground can be worked in the spring, as these love cool weather. Provide a sturdy trellis, fence, or netting immediately, as these vines need something to climb right away. Keep the soil consistently moist and mulch the base of the plants to keep those roots cool as it warms up. Pick the flowers often; removing the blooms for bouquets actually stimulates the plant to produce more flowering stems. These are cool-season annuals that will eventually decline once the high heat of mid-to-late summer arrive.
General Growing Tips For Your Seedling Tray
For professional greenhouse production, plant one rooted liner per 4-inch pot or three per 10-inch container. Maintain your media pH between 6.0 and 7.0 and provide a balanced fertilizer feed of 150 to 200 ppm Nitrogen. Sweet peas are cool-weather crops, so keep daytime temperatures between 55 and 65°F and nights around 45 to 50°F to ensure high flower quality and strong stems. While Mammoth types are early bloomers, they still require high light levels to prevent flower bud drop . Finishing time for a 4-inch pot is typically 6 to 8 weeks from transplant.
Pinching
You should pinch the plants once they reach about 4 to 6 inches in height to encourage better branching from the base, which significantly increases your total flower yield.
Spacing
For professional cut flower production, space your plants 6 to 12 inches apart. Because Mammoth Rose Pink is a vigorous climber, you must provide mechanical support, like 6-foot tall netting, to keep the stems straight and prevent the vines from tangling.
Pests
Closely monitor your crop for aphids, thrips, and spider mites
Disease
The most common issues are powdery mildew and botrytis, especially when humidity is high.
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.
