Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

DescriptionLooking to add a bit of sunshine to your garden? Consider planting the 'Karma Gold' dahlia ! These dahlias deliver a warm, sunny glow with 6" double blooms, golden yellow petals, and a butterscotch center. These flowers are renowned for their strong stems and long vase life as a cut flower, but also make for a beautiful bright border. Plant the 'Karma Gold' dahlia this year to ensure late summer sunshine.
Native to Mexico and South America, dahlias are late-season bloomers that boast flowers from midsummer to the first frost in fall. They thrive in hot and sunny gardens, but gardeners in cold climates can enjoy them as well! Since they have tuberous roots, cold-climate gardeners can dig up the tubers and save them for the following season. Dahlias are a perfect fit for borders, cottage gardens, pollinator gardens, and they make a lovely addition to any cut flower bouquet. When given full sun, moist soils, and protection from wind, they'll reward you with months of colorful flowers.
Great Garden Tip: tubers will need to be lifted in fall in zones 3-7 to grow the following yearDetails Botanical name: 'Karma Gold' Dahlia Common name: Dahlia Zone: 9-11 Sun exposure: Full Sun (6+ hrs sun) Height x width: 40” tall x 18-24” wide Flower color: Yellow/Gold Foliage color: Green Season of Interest: Summer-fall Bloom time: Summer - fall Features: heat tolerant, container plants Uses: Border, cottage gardening, massing, pollinator plant, wildflower How To Grow Soil: Rich and well-draining soil. Light: Full sun. Dahlias thrive in 6-8 hours of direct sun, with an additional fondness for morning sun. Water: Average. Water once or twice a week, allowing the top inch of soil to dry up between watering. Keep Dahlia foliage as dry as possible in order to discourage disease. Spacing: 18" apart Fertilizing: Apply a 5-10-10 or 10-20-20 fertilizer after the plants sprout. Reapply every three weeks from mid-summer until fall. Winterizing: Lift in zones 3-7 before first frost. Zone 8-10 may either lift their tubers before frost or cover thickly with mulch. Maintenance & Pruning: Cut back foliage in preparation for digging the tubers up before the first frost. Leave around 1-2" of stem on the tubers.
