Planting Guides

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.

    Comments about High Country Gardens Sights of Summer Semi-Dinnerplate Dahlia Bulbs:

    I'm a super first time gardener - like I have never planted anything from seed before!

    I was determined to grow a 'hummingbird' garden on our porch in Northern California. I read that Dahlias were both hardy as well as hummingbird favorites (plus I think they are beautiful) so I gave this 'Sights of Summer' a try.

    Of all the flowers I've planted, these were the first to grow a bulb and bloom. My regular hummers visit their nectar feeder all throughout the day and now that the dahlia is peeking over the railing, they are investigating them too!

    With the rest of the flowers about to bloom, I'm excited to watch all the mischievous activity of my little hummingbirds. Overall, excellent quality!

    The tubers arrived moist and I planted them as directed.

    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).
