Erysimum Winter Joy Improved 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. 

Lilac flowers bloom from early spring to early summer. 

We recommend one pinch during bulking or no pinch for this plant.

Space containers for adequate airflow and sunlight around the base and foliage of each plant.

Do not use PGRs after bulking. Sumagic at 5 ppm can prevent legginess during bulking.

You may see slugs, snails, or flea beetles.

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. 

We recommend planting one rooted liner per container. Use well-drained soil and completely bury the ellepot in the center of the pot.
