How to Plant a Thimbleberry Bush

1). Soak the thimbleberry seeds in warm water for a full day to soften their outer shells.
2). Fill small planters with a potting soil rich in humus.
3). Mix the seeds with an equal amount of sand and sow the mixture thinly onto the soil in the planters.
4). Cover the seeds with a thin layer of humus and spray them with a water mister.
5). Set the planters in a refrigerator set to 40 to 50 degrees F until they begin to sprout. This typically requires two to three months.
6). Remove the thimbleberry seedlings from the planters and plant them outside during the spring in a shady location. Keep the soil moist but not wet.
7). Transplant the thimbleberries to a permanent location after one year. Thimbleberries grow best in a loamy soil, but can tolerate a variety of soil types as long as the soil remains well drained.
8). Water the plants with one inch of water per week during the growing season. Thimbleberries are moderately drought-tolerant once they establish their root system.
