Do dinnerplate dahlias come back every year?
Dinner plate dahlias are tender perennials, so they will come back every year in regions where they don’t have hard winters. If you live in USDA hardiness zone 7 or below, you will need to dig up and store the plant’s tuberous roots indoors before planting out again in the spring to see them return annually. Move them to a location – either indoors or out – that won’t dip below freezing, has good air circulation, and receives indirect sunlight. After your tubers have dried, cut back the rest of the dahlia stem with pruners or a sharp knife. Set tubers out to dry for several weeks before storing them for the winter.Despite a popular misconception that tubers must be grown in the ground, dahlias can actually do quite well in pots if cared for properly. They are hardy plants, and there’s some important factors to consider, like the size of your dahlias, before you start planting in pots or containers.Dahlia tubers can be started into growth in March or April in pots undercover, and then planted out in the garden in late May and June.

Take time to remove the entire stem right back to a main stalk. This encourages the plant to produce longer stems and also promotes good air circulation within and around the plant.Dahlias grow best when they receive a consistent supply of water. Drip irrigation is ideal, as it directs moisture to the root zone while keeping the foliage dry.

As they become taller, the plants will become bushier if the central growth tips are pinched out; this will also encourage flowers buds to develop on lateral growth.When temperatures rise above 85°F or nights don’t cool down, dahlias may begin exhibiting signs of stress. These include stunted growth, wilting leaves, reduced flower production, misshapen flowers, and increased susceptibility to disease and pests.Leafgro is a high-quality organic compost, and dahlias respond very well to it.
