1. Use well-drained soil in a sunny location.
2. Cut Erysimum back by half after it flowers to encourage a dense habit.
3. Water regularly in extreme heat and during the first year as the plant establishes a healthy root system.
General Growing Tips For Your Rooted Cutting Liner
For best results with Winter Joy Improved, plant one plug per 4-inch, 6-inch, or 1-gallon container. Use well-drained soil in full sun or partial shade, a pH of 5.7-6.2, and medium feed (200-300 ppm N). Bulk to about half the finished size in warm temperatures (65+) and then vernalize at cool temperatures (35-46) for 4-6 weeks. Grow under high light intensity. Apply Sumagic at 5 ppm during bulking, but do not pinch or use PGRs once bulking is complete. This plant may be affected by downy mildew and you may see slugs, snails, or flea beetles.
Six-inch pots take 6-7 weeks of bulking; 1-gallon pots take 8-10 weeks of bulking; 2-gallon pots take 12-15 weeks of bulking. This variety doesn't do well in 4-inch containers. Each size container needs 4-6 weeks of vernalization after bulking.
Flowering
Lilac flowers bloom from early spring to early summer.
Pinching
We recommend one pinch during bulking or no pinch for this plant.
Spacing
Space containers for adequate airflow and sunlight around the base and foliage of each plant.
Height Control
Do not use PGRs after bulking. Sumagic at 5 ppm can prevent legginess during bulking.
Pests
You may see slugs, snails, or flea beetles.
Disease
This plant can be susceptible to powdery mildew. This fungus spreads in the air and is most likely in cool, humid weather. Treat when you first see the tell-tale powdery white spots appear or preventatively with a 2 ppm drench of Bonzi.
Planting Winter Joy Improved Liners
We recommend planting one rooted liner per container. Use well-drained soil and completely bury the ellepot in the center of the pot.
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.
