Need a soil composition recommendation and siting for Y.Rostrata 'blue saffires'
If anyone has had success in getting a Western Yucca to succeed in the wetter and cooler zones, I sure could use some advice on soil amendments.
I know I will need to build a small mound for drainage but unsure about anything else including siting. I did plant a Y.Elata about 12 years ago and it has performed great in pea gravel and sand on a mound. Im not sure if this will work for Rostrata.
I know black garden soil is DEATH.
To make matters even more difficult is
*frequently wet and cold winters most all nights
*freezing fog and frost frequently.
Im almost thinking about just keeping them potted
appreciate any advice on whether I should plant or pot , soil advice and siting.
* below is a description and pic .
of course that z5b dont mean diddly squat in wet winters I dont believe.
The stunning powdery-blue foliage of 'Sapphire Skies' is one of the hardiest of all trunk-forming yuccas. It grows to 4-feet tall x 3-feet wide in full sun and well-drained soil. The thin pointed blades, relatively short and flexible, form a luminous specimen plant that would be well suited for the dry garden. Spectacular spires of ivory flowers bloom in summer. Hardy in zone 5b to 10.
