It is not usually necessary to control plant height in the early stages of production. Controlled-release fertilizers can be applied as a top-dress onto the media surface using the medium labeled rate, or incorporated into the growing mix prior to planting at a rate equivalent to 0.9 to 1.1 pounds of elemental nitrogen per yard of growing medium. Growers using water-soluble fertilizers either apply 150-200 ppm of nitrogen as needed or feed with a constant liquid fertilization program using rates of 75-100 ppm of nitrogen with every irrigation. Geum can be grown using low to moderate fertility levels.

It is best to keep them uniformly moist, but not consistently wet. They require an average amount of irrigation and do not tolerate extended periods of saturated or overly dry growing conditions. Geum performs best when they are grown in a moist, well-drained medium with a slightly acidic pH: 5.8-6.4. When transplanting, the plugs should be planted so the original soil line of the liner is even with the surface of the growing medium of the new container. 'Totally Tangerine' can be started in either the fall prior to or in the spring of the same year they are intended to be sold. Growers commonly transplant one rooted liner into 1-gallon or larger sized containers. Plant Patent has been applied for (PPAF) propagation without permission of the applicant is illegal at this time. Geum 'Totally Tangerine' is vegetatively propagated from softwood or root cuttings. Avens attract butterflies into the gardens and are resistant to deer and rabbit feeding. 'Totally Tangerine' makes a great addition to herbaceous perennial borders, are well suited for commercial landscape plantings, and makes a great cut flower. Once established in the landscape, geum has shown good tolerance to drought. Geum performs well across much of USDA Hardiness Zones 4 to 9 and AHS Heat Zones 9 to 3 where they prefer to be grown under partial shade however they can tolerate several hours of direct sunlight each day. With the flowers being sterile, it continues to bloom and bloom, producing hundreds of warm, bright-apricot to tangerine-orange single flowers over the course of the growing season. It blooms slightly later than many of the geum cultivars on the market blooming begins in the late spring, but unlike most cultivars, flowering continues through the heat of summer. In the landscape, an individual plant will grow to 18 inches across and reach 24-30 inches when in flower. 'Totally Tangerine' develops attractive mounds of deep-green, fuzzy pinnately lobed leaves. Thanks to the breeding efforts of Tim Crowther from the United Kingdom, there is now an impressive, long blooming geum cultivar on the market. Those who like the bright, cheerful displays of color that many geum cultivars deliver in the early spring, but wish these plants would bloom into the summer months, I'd like to introduce you to Geum x hybrid 'Totally Tangerine' (aka 'Tim's Tangerine' PPAF).
