General Growing Tips For Your Rooted Cutting Liner
For best results with Glacier Sky Blue, plant one rooted liner per 4-inch or gallon container. Use a well-drained soil in full sun with a pH of 5.5-5.9, light feed (75-100 ppm), and an SME EC of 1.5-2.1 mS/cm or Pourthru EC of 2.3-3.2 mS/cm. This plant requires bulking and vernalization. Follow 5-6 weeks of bulking at 64-66 degrees with 7-8 weeks of vernalization at 45-50 degrees. Vernalization should occur when foliage fills 1/2 to 2/3 of the pot diameter. Use low feed when entering and during vernalization. Aubrieta is day-neutral and does best with 6,000-8,000 fc light. Finish in daytime temperatures of 66-68 degrees and night-time temperatures of 58-60 degrees. Finishing time for a 4-inch container is 5-6 weeks, or 21 weeks including bulking and vernalization. Plant rooted plugs in final containers in mid-fall for spring sales, doing the bulking and vernalization process throughout the fall and winter. Provide sufficient airflow to prevent pythium root rot and botrytis. You may see aphids.

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.
