General Growing Tips For Your Rooted Cutting Liner
For best results with Impatiens Sunpatiens Vigorous Sweetheart White, plant one rooted plug per 4- or 6-inch container or three per 10-inch container. Use a well-drained soil with a pH of 5.8-6.2, temperatures of 68-79 daytime and 59-64 nighttime, and low feed (75-150 ppm N). Provide light at 4,000-9,000 fc and grow plants on the dry side. This plant doesn't require pinching or PGRs under ideal conditions. Use Daminozide if needed. You may see thrips, aphids, and mites. This hybrid is resistant to downy mildew but can develop botrytis, pythium, and necrotic spot virus.
Flowering
White flowers with red centers bloom from spring through fall.
Pinching
Pinching this plant will delay flowering by two or three weeks. For on-schedule plants, do not pinch. Pinching can be an effective timing tool to delay flowering.
Spacing
Space containers to allow airflow and sunlight penetration around the base and foliage of each plant. Growing this plant pot-tight will cause stretching. We recommend spacing 4-inch containers 7" apart and 10-inch containers 18" apart.
Height Control
This plant doesn't require PGRs when it grows dry and cool with low feed. Use a spray of Daminozide at 1,000ppm if needed.
Pests
You may see thrips, aphids, and mites.
Disease
Impatiens Sunpatiens Vigorous Sweetheart White isn't prone to disease and offers superior resistance to downy mildew. Necrotic spot virus, botrytis, and pythium rot can affect this plant. Prevent disease by following these steps:
1. Practice good sanitization in your greenhouse, using clean media and containers for planting and disposing of any infected materials promptly.
2. Water at the base of each plant in the morning, allowing the soil to dry out between waterings.
3. Provide good airflow in your greenhouse. We recommend using horizontal airflow fans.
4. Give containers plenty of space so air and sunlight can reach the soil level of each plant.
Planting Impatiens Sunpatiens Vigorous Sweetheart White Liners
We recommend planting one rooted liner per 4- or 6-inch container or three per 10-inch container. Use a well-drained soil and completely bury the ellepot centered or evenly spaced in the container.
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.
