As with most in Ranunculaceae, seeds that are not planted soon after harvesting should be stored moist-packed in vermiculite to avoid dormancy and viability issues. As with most in the Ranunculaceae and Papaveraceae families, they dislike root disturbance. As a result, they are not described as being "heavy feeders" (needing a higher quantity of fertilizer versus most other flowering plants)-unlike gardeners' delphiniums. Aconitum plants are typically much longer-lived than the closely related delphinium plants, putting less energy into floral reproduction. All parts of these plants should be handled while wearing protective disposable gloves. Aconitum species can be propagated by divisions of the root or by seeds, with care taken to avoid leaving pieces of the root where livestock might be poisoned. Most Aconitum species prefer to have their roots cool and moist, with the majority of the leaves exposed to sun, like the related Clematis. Species not used in gardens tend to require more exacting conditions (e.g. The species typically utilized by gardeners fare well in well-drained evenly moist "humus-rich" garden soils like many in the related Helleborus and Delphinium genera, and can grow in the partial shade. The plant thrives in wet soil with good drainage, amongst fireweed, false hellebore, yarrow, alpine rice, alpine foxtail, nootka lupine, alpine bistort, devil's club, and cow parsnip in the rocky, tundra-like, mountainous terrain of Turnagain Pass, Alaska.
