Last year I underestimated the growth of my hostas and planted dahlias somewhere in their vicinity.
Stake and support dahlias , gladioli, chrysanthemums and other top-heavy border plants.
Very fancy fences can be created from tall flowering annuals such as cleome, cosmos, dahlias , sweet peas and sunflowers for a display of spring, summer and autumn colour.
After the first frost has killed back the foliage, dig and store tender perennial bulbs such as dahlias and gladiolus that can't survive the winter in the ground in a cold climate.
Replace fading cool-season annuals with heat lovers like celosias, dahlias , marigolds, petunias, salvias, and verbenas.
Don't forget the flower beds - plant dahlias and gladioli now.
Summer-flowering bulbs such as dahlias , begonias and anemones bring variety, texture, unique color and long flowering times to summer gardens.
Store bulbs and tubers of begonias, caladiums, cannas, dahlias , and gladioli in a cool, dry place until March, when they can be started indoors.
Start begonias, caladiums, callas, cannas, and dahlias in pots indoors on a sunny windowsill.
For added summer color, Shari tucks tall ageratum, ‘Bluebird’ nemesia, calibrachoa, dahlias , and impatiens between the shrubs.
