General Growing Tips For Your Rooted Cutting Liner
For best results with Sunburst, plant one rooted plug per 4-inch container or 10-inch basket. Use a well-drained soil with a pH of 5.8-6.2, EC of 0.6-0.9, light feed (100-150 ppm N) of a balanced 10-10-10 fertilizer, and average daily temperatures of 55-65 degrees. Pinch once seven days after transplanting and a second time if desired. This plant benefits from cold treatment and doesn't require PGRs. This plant isn't prone to pests. You may see rust and leaf spots.
Flowering
Star-shaped yellow flowers bloom in May-July.
Pinching
Pinch once seven days after transplanting. Pinch a second time if desired.
Spacing
Space hanging baskets at 2' centers and 4-inch containers about 6-8 inches on center for airflow and sunlight penetration around the base of each plant. Growing in 1801s, this plant will need growth control by pinching.
Height Control
This plant isn't response to PGRs and doesn't tend to stretch tall. Pinch properly to control growth, especially in 1801s.
Pests
You may see whiteflies, aphids, and spider mites.
Disease
This plant is prone to rust and leaf spots.
Yellowed, withering leaves are a sign of rust. Treat immediately by removing affected plant parts. Use a preventative fungicide for a recurring infestation. Prevent rust from spreading by removing all diseased debris at the end of the season and using careful sanitary practices in your greenhouse.
Fungal leaf spot doesn't typically cause Lysimachia to die, but cosmetic blemishes on foliage are undesirable. This broad group of diseases shows up as small brown lesions on foliage or flowers. Prevent infection by watering at the base of each plant in the morning, allowing the soil to dry between watering, avoiding standing water, and providing good airflow in your greenhouse. Apply a fungicide to treat leaf spot if the integrity of the plant is at stake.
Planting Sunburst Liners
We recommend planting one rooted plug per 4-inch container or 10-inch basket. Use a well-drained soil and completely bury the ellepot in the center of 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.
