For the Smoke Bush 'Smokey Joe', water the plant thoroughly when the top inch of soil feels dry, which typically means once a week, depending on the climate and weather conditions. Use a soaker hose or drip irrigation to apply water directly to the base of the plant, avoiding wetting the foliage to prevent fungal diseases. Each watering session should supply the Smoke Bush with about 1-2 gallons of water, encouraging deep root growth. Adjust your watering schedule during hot, dry periods by increasing the frequency, and reduce watering during rainy seasons or when temperatures drop.
The Smoke Bush 'Smokey Joe' prefers full sun to partial shade, thriving best with at least 6 hours of direct sunlight daily. Plant it in a location where it can receive unfiltered sunlight for the majority of the day. Partial shade is acceptable, especially in the hottest regions, but too much shade can lead to sparse foliage and fewer of the plant's characteristic smokey plumes.
The Smoke Bush 'Smokey Joe' is hardy and can tolerate a range of temperatures, but it grows best within USDA hardiness zones 5 through 8, which typically offer a temperature range of -20 to 80 degrees Fahrenheit. It can survive minimum temperatures down to -20 degrees Fahrenheit, and while it can withstand heat well, it should be protected from extreme temperature fluxes above 80 degrees Fahrenheit to prevent heat stress.
Prune the Smoke Bush 'Smokey Joe' in late winter or early spring before new growth begins to maintain its shape and encourage denser foliage and more vibrant color. Prune out any dead, damaged, or crossing branches and thin out the center of the plant to improve air circulation. Pruning can be done annually, but the plant can also go several years without pruning if desired.
The Smoke Bush prefers well-draining soil with a pH of 5.5 to 7.5. A good mix can include loam, sand, and a small amount of organic matter to ensure drainage and fertility.

- Life cycle
Smokey Joe, scientifically known as Cotinus coggygia 'Lisjo' (PBR), begins its life cycle with seed germination, which occurs in a warm and moist environment, preferably in spring. Following germination, the seedling emerges, establishing a root system and producing its first set of true leaves. As a young plant, or sapling, it undergoes vegetative growth, forming a robust, multi-stemmed shrub with characteristically round, bushy foliage. Upon reaching maturity, which can take several years, Smokey Joe flowers in the summer, displaying feathery, smoke-like inflorescences that give the plant its common name. After flowering, the plant produces small, hard seeds, which are disseminated by various means, including wind and wildlife, to begin a new generation. Throughout its life, Smokey Joe experiences seasonal changes, with foliage potentially turning vibrant shades of yellow, orange, or red in the fall before entering dormancy in winter.
Spring to early summer
Propogation: The common name for Cotinus coggygria 'Smokey Joe' is Smoke Bush, and the most popular method for propagating this plant is through softwood cuttings. Softwood cuttings are typically taken in late spring or early summer when the new growth is still green and flexible. Cut a 4-6 inch (10-15 cm) section from the tip of a healthy branch, making sure it includes at least two sets of leaves. Remove the leaves from the lower half of the cutting to expose the nodes where roots will form. Dip the cut end in rooting hormone to encourage root development and plant the cutting in a well-draining potting mix. Keep the soil moist but not waterlogged, and cover the pot with a plastic bag to maintain humidity. Roots should develop within a few weeks, and once established, the new Smoke Bush plants can be transplanted to their permanent location.
