Dahlia ‘Topmix Salmon’ forms a low, upright clump covered with single flowers measuring about 45 mm (2 in). Their vibrant orange florets have a soft pinkish-red shade along the midrib, purplish-red veins, and a yellowish-green base dotted with dark red; the central yellow disk remains fully visible. The reddish-brown stems and green foliage highlight this nuanced salmon palette. Van Noort's No. 1 tuber reaches about 50 cm (20 in) in height and spread. From summer to the first frost, its continuous blooms animate borders, small beds, patios, and containers while remaining accessible to pollinating insects.
Plant the tuber after the last frost, when the soil has warmed, in a sheltered, full-sun location. Lay it 10 cm (4 in) deep, bud facing upward, in fertile, humus-rich, moist, and freely draining soil. Leave 50 cm (20 in) around the crown to allow the compact clump to spread. Water sparingly before sprouting, then deeply at the base when the surface is dry. Pinch the young shoot at about 20 cm (8 in) to encourage branching. Incorporate mature compost before planting and fertilize moderately, with more potassium once buds form. Avoid excess nitrogen, standing water, and repeated watering on the foliage.
Place Topmix Salmon at the front of a border or in a stable pot near a walkway, where its small salmon-colored flower heads can be observed up close. Pair it with white alyssum, blue salvias, purple verbenas, cream calibrachoas, and fine grasses. The single flowers give bees, hoverflies, and butterflies direct access to pollen and nectar; therefore, avoid pesticides on the flower heads. Regularly remove spent flowers to encourage reblooming and monitor for slugs, aphids, and spider mites. In Quebec, after the first frost, lift the tuber, let its surface dry, label it, and store it in a cool, dark, dry, and frost-free place until spring.

Growing method
After the last frost, loosen a sunny area to a depth of 12 inches (30 cm) and incorporate mature compost. Place the tuber horizontally 4 inches (10 cm) deep, bud side up, then leave 12 inches (30 cm) around the crown. Backfill without compacting and water only if the soil becomes dry before emergence. Pinch the shoot 8 to 12 inches (20 to 30 cm) above a pair of leaves. Immediately install a sturdy stake. When growth accelerates, water deeply at the base and fertilize sparingly, favoring potassium for the buds. Tie the stems with soft ties, harvest flowers when almost open, and remove spent blooms. After frost, cut the stems, lift the tuber, allow its surface to dry, and store it in a cool, dry, frost-free place. The salmon-orange contrast with purplish-salmon tips remains clearer when the plant receives at least six hours of direct sunlight and regular feeding without excess nitrogen. An early-installed stake supports the 2-inch (5 cm) flower heads after rain without compressing the stems or damaging active roots. Remove faded flowers before seed formation so that the clump directs its energy towards new buds until the first frost.

Watering
Water regularly to keep the soil evenly moist without overwatering. Reduce watering before autumn tuber lifting. Water sparingly before emergence, then deeply at the base when the surface dries. Avoid excess nitrogen, standing water, and repeated watering on the foliage. In Quebec, after the first frost, lift the tuber, let its surface dry, label it, and store it in a cool, dry, dark, and frost-free place until spring.
Soil type
Prioritize a humus-rich soil that retains moisture while allowing excess water to drain. Check drainage after rain: water should be able to leave the root zone. Work the soil when it is not waterlogged to avoid compacting it. Adapt amendments to its actual texture. For container plants, use appropriate potting mix and a pot with drainage holes. Keep these openings clear and avoid any accumulation of water in the saucer.
Fertilization
Incorporate mature compost before planting. At the start, use a balanced formula low to moderate in nitrogen, then favor more potassium when buds appear. Follow the indicated dose and then water. Too much nitrogen produces tender stems and fewer flowers. The salmon-orange contrast with purple-salmon tips remains sharper when the plant receives at least six hours of direct sun and regular feeding without excess nitrogen.
Seasonal care
In spring, inspect the tuber, remove only rotten tissue, and plant after the last frost in warmed soil. Install support immediately. Until emergence, avoid repeated watering. In early summer, pinch the shoot at 20 or 30 cm (8 to 12 in), tie new stems, and keep the soil moist without saturation. As soon as buds appear, fertilize moderately with more potassium. In summer, water deeply at the base during dry periods, harvest nearly open flowers, and continuously remove faded flower heads. Watch out for slugs, aphids, earwigs, spider mites, and gray mold. After the first frost, cut the stems, gently lift the tuber, let its surface dry, label it Topmix Salmon, and store it in the dark, cool, dry, and frost-free. Check it monthly during winter. The salmon-orange contrast with purplish salmon tips remains sharper when the plant receives at least six hours of direct sun and regular feeding without excess nitrogen. A stake installed early supports the 5 cm (2 in) flower heads after rain without compressing the stems or damaging active roots. Remove faded flowers before seed formation so that the clump directs its energy toward new buds until the first frost. Always water slowly at the base, then allow the top layer to breathe to maintain a balance between moisture, oxygen, and drainage. The salmon-orange shades with purplish salmon tips pair particularly well with blue, white, salmon perennials and light grasses.
Container growing
A garden,within reach.
Recommended pot size
12 to 15 L, 30 cm (12 in) diameter
Container growing requires you to provide sufficient volume for the roots and the plant's final height. Choose a stable pot with drainage holes and a suitable growing medium. Leave enough space to respect the recommended depth and spacing, rather than crowding the plants to immediately fill the pot. Place the container in the recommended exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting directly in the ground. Therefore, plan for a wintering location from the outset that is compatible with the plant's needs and your region's climate. Plant in spring when all risk of frost has passed and the soil has warmed sufficiently. Choose a sunny spot, sheltered from strong winds, in fertile and well-drained soil. Arrange the tuberous roots with their crown and buds facing upwards, without breaking the fragile attachments. Install a stake at planting if support will be necessary, to avoid damaging the roots later. Water sparingly at the start, then adjust watering to the foliage growth. Constantly waterlogged soil around the tubers should be avoided, especially before the first shoots appear. Plan to bring the storage organs indoors, away from frost, for the Quebec winter.

Companion plants
To accompany Dahlia ‘Topmix Salmon’, you can consider cosmos, zinnias, or ornamental salvias. Choose neighboring varieties based on their height, flowering period, and the colors you wish to combine. Most importantly, ensure that their exposure and water needs are suitable for the same location. Maintain enough distance so that the leaves do not shade young shoots and so that you can easily access each plant during maintenance. These associations are for composing the garden's aesthetic; they do not guarantee protection against pests or diseases. Adjust the arrangement after observing one growing season.
Frequently asked questions
Your questions,answered.
When to plant the Topmix Salmon dahlia?
Plant the tuber after the last frost, when the soil has warmed up and is no longer saturated. Plant it 4 inches (10 cm) deep, bud facing upwards, in fertile, humus-rich, well-drained soil. Leave 12 inches (30 cm) around the crown and install a support immediately. In a cold region, start it in a pot four to six weeks earlier, then gradually acclimate the shoot before planting it out. Water very sparingly before emergence to prevent rot, then increase watering when the roots and stems are active. Full sun develops strong stems and intensifies the salmon-purple and black contrast.
What colors do Topmix Salmon flowers come in?
Topmix Salmon is more beneficial to pollinators than fully double dahlias because its central disk remains open. Bees, hoverflies, and butterflies can directly access pollen and nectar when the flowers are fresh. Place the pot or border in the sun, avoid spraying pesticides on the flower heads, and leave several flowers open during the day. Then, remove faded flowers to encourage new bud formation. Combine with alyssum, salvias, verbenas, or other single flowers to provide complementary resources before and after peak dahlia bloom periods. In a small garden, this succession also maintains the activity of beneficial insects. A shallow, frequently replenished saucer of water usefully completes the welcome during hot days. Finally, the exposed center allows for observation of visits without handling the flowers or disturbing the insects.
How to support and make Topmix Salmon flourish?
Install a sturdy stake at planting to avoid damaging the roots later. Tie the stems with soft ties as they grow. Pinch back the young shoots to 20 to 30 cm (8 to 12 in.) to encourage multiple branches. Water deeply at the base when the surface is dry, then allow excess water to drain. Incorporate mature compost initially, then use a moderate fertilizer, richer in potassium once buds form. Avoid excessive nitrogen, which produces tender stems and abundant foliage. Regularly remove faded flowers so that energy is directed to the next buds until frost.
Can Topmix Salmon grow in a large pot?
Yes, choose a stable container of 12 to 15 L, deep, well-drained, and filled with rich but aerated potting soil. Plant a single tuber 10 cm (4 in) deep and insert the support before the roots develop. Place the pot in full sun, protected from gusts of wind. Water sparingly before sprouting, then abundantly when the top layer dries, without leaving water in the saucer. Apply a moderate liquid fertilizer, richer in potassium once buds appear. Turn the container weekly, pinch back new growth, and remove faded flowers to maintain a balanced shape and generous blooms.
How to overwinter Topmix Salmon in Quebec?
After the first frost blackens the foliage, cut back the stems, leaving a short stub. Lift the tuber with a fork, working far enough away not to damage it. Gently remove excess soil, allow the surface to dry in a ventilated area, and clearly label it Topmix Salmon. Store it in a dark, cool, dry, and frost-free place, in a slightly insulating material that limits drying out without retaining water. Inspect it monthly. Only remove parts showing active rot and increase ventilation if condensation appears. Wait until the last spring frost and warm soil before replanting.
