Temperature Requirements
This plant is native to North America and can tolerate a wide range of temperatures. It can survive in USDA hardiness zones 3 to 9, which means it can tolerate minimum temperatures as low as -40°F (-40°C) and maximum temperatures as high as 100°F (38°C).
Soil Requirements
Rhus aromatica var. simplicifolia prefers well-drained soils that are slightly acidic to neutral in pH. It can tolerate a wide range of soil types, including sandy, loamy, and clay soils as long as it's well-drained. It is adapted to dry soils and can tolerate drought conditions.
When planting, it's best to amend the soil with organic matter, such as compost or peat moss, to improve soil fertility and water retention. The addition of a slow-release fertilizer can also help promote healthy growth and development.
Cultivation Methods
Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. is a low-maintenance plant that grows well in a variety of soil types. It can be grown from seed or propagated through cuttings. If growing from seed, plant in a well-draining soil mix and keep the soil moist until seedlings emerge. When propagated from cuttings, make sure the cuttings come from healthy plants. Root in a rooting hormone and plant in a well-draining soil mix. Place the plant in a location with partial shade or full sun exposure.
Watering Needs
The Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. plant prefers moderate watering. Water the plant when the top one inch of soil is dry to the touch. Avoid overwatering, as this can lead to root rot and other problems. During the plant's dormant period, reduce the frequency of watering.
Fertilization
The Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. plant benefits from occasional fertilizer applications during the growing season. Use a balanced fertilizer that provides equal amounts of nitrogen, phosphorus, and potassium. Apply according to package instructions, making sure not to over-fertilize as this can damage the plant.
Pruning
Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. does not require pruning, but it can be beneficial to keep the plant looking neat and tidy. Prune in late winter or early spring before the growing season begins. Remove any dead or damaged branches and shape the plant as desired. Be sure to use clean, sharp pruning shears to avoid damaging the plant.
Propagation of Rhus aromatica Ait. var. simplicifolia (Greene) Cronq.
Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. is a shrub that can be propagated by different methods, including:
Seed propagation
The seeds of Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. can be collected in the fall, as they start to dry and turn brown. The seeds should be cleaned and stored in a dry and cool place until they are ready to be planted. To increase germination rates, the seeds can be soaked in water for 24-48 hours before planting. They should be planted in well-draining soil, either directly in the garden or in pots, and kept moist until they germinate, which can take up to several weeks.
Cuttings propagation
Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. can also be propagated by cuttings. Softwood cuttings can be taken in the early summer, and hardwood cuttings can be taken in the late fall. The cuttings should be about 4-6 inches long, and the leaves on the lower half should be removed. The cuttings should be dipped in rooting hormone and planted in a well-draining soil mix, preferably in a greenhouse or under a plastic cover to maintain high humidity. The cuttings should be kept moist and protected from direct sunlight until they develop roots, which can take up to several months.
Layering propagation
Rhus aromatica Ait. var. simplicifolia (Greene) Cronq. can also be propagated by layering, which is a process where a branch is bent down to the ground and covered with soil to stimulate root growth. The layering should be done in the early spring, and the branch should be wounded at the point where it will be covered with soil. The branch should be covered with soil and kept moist until roots have developed, which can take up to several months. Once roots have developed, the layer can be separated from the mother plant and transplanted to its own location.
