Propagation recommendations (plant seeds, vegetative parts, cuttings, etc.)

The most successful means of propagating this plant are through bare rootstock. The best time to plant out on the Pacific coast is in mid- to late October, before the heavy rains have begun in full but the weather is sufficiently cool that the new plants will not lose a lot of moisture. These plants should be planted such that the crowns are even with the soil.

Soil or medium requirements (inoculum necessary?)

Moist soil.
