Cultivation Methods:
Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders. thrives in full sun to partial shade in moist to dry soils. It can grow in various soil types, including loam, clay, sand, and gravel. The plant prefers well-drained soil with a pH of 6.0 to 7.0. It is easy to grow from seed, and the seeds can be sown directly in the garden or started indoors before transplanting. The plant has a deep root system, which makes it drought-tolerant and needs little watering once established.
Watering Needs:
Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders. needs moderate watering. It is important to ensure that the soil is moist but not waterlogged. Overwatering can lead to root rot and other fungal diseases. The best time to water the plant is in the morning so that the leaves have enough time to dry before the evening. If you live in an area with high humidity, it is advisable to water the plant less frequently to avoid moisture build-up.
Fertilization:
It is not necessary to fertilize Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders. as it can grow well in poor soils. However, you can add organic matter like compost to the soil before planting to improve soil fertility. If you decide to fertilize the plant, use a slow-release fertilizer in the spring and follow the recommended instructions on the package. Avoid using high-nitrogen fertilizers as this can encourage leaf growth at the expense of flower production.
Pruning:
Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders. does not require pruning unless you want to manage its size or shape. You can deadhead the flowers after blooming to encourage more blooms and prevent self-seeding. Use a pair of garden shears to cut back the plant to one-third of its size in the fall to encourage new growth in the next growing season. Take care not to damage the plant while pruning.
Propagation of Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders.

Propagation of Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders. can be done by seed or division.
Seed Propagation
The most common method of propagating Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders. is through seed. The seeds can be collected from the mature capsules that develop after the flowers have bloomed. The best time to collect the seeds is when the capsule starts to dry and turns brown. The seeds should be sown in a well-draining soil mix during the fall or early spring. The soil should be kept moist, but not waterlogged. The seeds will germinate in approximately 10-14 days, and the plants can be transplanted outdoors after the final frost has passed.
Division Propagation
Propagation of Papaver radicatum Rottb. ssp. alaskanum (Hultén) J.P. Anders. can also be done through division. This method is best done in the fall or early spring when the plant is dormant. The plant should be dug up carefully, and the root ball should be gently separated into smaller sections. Each section should have at least one growing point, and the smaller roots should be trimmed back. The sections can be replanted in a well-draining soil mix at the same depth as they were previously growing. The soil should be kept moist until new growth appears.
