Tried & True Dinnerplate Dahlia Collection
Tried & True Dinnerplate Dahlia Collection
With our Tried & True Dinnerplate Dahlia Collection, three of the classics are yours for a color-filled summer. Dinnerplate Dahlia ‘Thomas Edison’ flowers with almost electric purple double blooms, ‘Kelvin Floodlight’ Dahlia lights up the garden with bright clear yellow flowers and ‘Babylon Red’ Dahlia shines with fire engine red blossoms. All are tall plants that like full sun to perform their best. Plant them along a wall or be prepared to stake them if their flowers need support. Fantastic cut flowers, the more you cut them, the more they bloom. Butterflies and hummingbirds love them too. Dahlias are some of the easiest and most rewarding flowers to grow, and we make it easy to get started with this fabulous trio. Collection of three varieties, 9 bulbs (tubers) total.

Soil Preparation: Remember that proper soil preparation is the key to healthy, vigorous blooming perennials. Use Yum Yum Mix and a high quality compost at recommended rates to prepare the soil. Inoculate the plant roots with Plant Success mycorrhizal inoculant. Planting: Plant according to the mature size of the plant. Don’t be tempted to put the plants too close based on their size in the pots. They’ll grow quickly and cover the space shown in the planting map. (Maps included only with Pre-Planned Gardens, not Collections.)
Fertilizing: Once annually in mid-fall, after plants begin to go dormant. Use Yum Yum Mix or Yum Yum Mix Winterizer at recommended rates to improve the soil and provide essential plant nutrients.Use it with high quality compost, mix half and half by volume and spread on top of the soil. Scratch it in lightly and water thoroughly. It is also beneficial to treat the plant roots with Plant Success® mycorrhizal root inoculant if you didn’t do so at planting time. (Inoculation only needs to be done once.)
Mulching: In arid climates mulching is very beneficial. Coarse textured composts, shredded leaves, pine needles and composted bark are all excellent mulch materials. Apply to a depth of 1-2 inches. Replenish annually (or as needed).
Summer Blooming Bulbs, including popular varieties such as gladiolus and dahlias, are planted in the spring and bloom in the summer. Most of these bulbs are tropical and require warm weather to be planted. There must not be any danger of frost and your ground temperature must have reached 55 degrees Fahrenheit before planting. Many of our summer blooming bulbs can be planted as perennials in zones 9-10 (zone 8 if mulched), but should be treated as annuals in cooler climates. You can lift them and store them in the fall, or bring patio pots inside before frost. See page 15 of our Planting Guide for a bulb depth planting illustration. Read our article about How To Grow Dahlias.
Growing Dahlias: Plant Dahlia tubers after spring frosts in good garden soil with full sun. Dahlias must be protected from high winds, so we suggest you position them against a wall or be ready to stake them. Keep the plants well-watered and free of bugs, applying flower fertilizer as they grow. Your dahlias will be in full bloom by July or August, with the enormous flowers continuing to bloom until frost. As frost threatens, pull up the roots and trim off the stems. You can store the tubers in a cool dry place until the following spring.

Q & A
Suggested Companion Plants:
USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
