Where to Plant

Dahlias can be grown in both containers and the ground, however they need soil that is rich enough to sustain their “heavy feeding” requirements, and wet places will not be able to support them. You should look for another location or treat the soil with organic material if you detect puddles 5-6 hours after a heavy rain. For the strongest stems and most flowers, plant your Dahlias where they will get full sun.

When to Plant

You should plant dahlia tubers in the spring when the soil temperature has warmed to 60 degrees Fahrenheit and there is no threat of frost. They can be grown as annuals in zones 2-7, or they can be dug up and stored for the winter in zones 8-11. To get a head start on the growing season, start your Tubers in containers indoors before transplanting them outside.

Soil Preparation for Planting Dahlias:

• Plant your Dahlias by breaking up the soil and adding compost to increase nutrition and drainage. Bringing in “fresh” soil can harm your newly budding Dahlias because of the pesticides and fertilizers commonly utilized in packaged soil.
• Bone meal should be incorporated into the soil approximately an inch below where the tubers will be planted. Before planting, add about an inch of dirt. Bone meal is an excellent source of nutrients for your growing plants’ tubers and roots. Bone meal can attract pets and other animals, so add crushed pepper if necessary to deter them.

How to Plant:

• When planting Dahlias in the garden, look for a spot that is well-drained and gets enough of sunlight. Design your location based on the mature size and spacing information supplied for each variety. A variety of tubers should be planted 18-24 inches apart, with the eyes facing up and their crowns at the soil line. Remove any air pockets in the soil by tamping down on the plants.
• Consider how much room you have to work with when selecting a pot to house your Dahlias in the garden. Use the cultivar information supplied to select cultivars that are less than 2 feet tall. You can add peat moss or perlite to the potting soil to increase drainage, if necessary. A variety of tubers should be planted 18-24 inches apart, with the eyes facing up and their crowns at the soil line. Remove any air pockets in the soil by tamping down on the plants. Place your plants where they will be exposed to as much sunlight as possible.

Stake Dahlias to Support Big Blooms

• Dahlias that reach a height of more than two or three feet need a support system to help them bear the weight of their many blooms.
• Stake the tubers as soon as they are planted to prevent damage to the plants, ensure a good harvest, and reduce future labour.
• You can support your Dahlias with bare branches from the garden, wooden pegs with twine crossed at various levels, or even tomato cages. Isn’t that beautiful right now? The blossom and foliage will soon cover up any visible supports.

Watering Dahlias

• If it hasn’t rained in your garden for several weeks, make sure to water the tubers after planting; otherwise, leave them dry.
• Before watering the Dahlias again, wait until the tops of the plants have emerged after planting.
• When the plants are actively growing, water them frequently and gradually increase the amount of water you give them as they become larger. In the beginning, they’ll need to be watered once a week, growing to twice a week as they mature.
• Watering should be adjusted based on the current weather conditions. Flowers grown in pots or areas with high temperatures will require more frequent watering than flowers grown in the ground.

Topping Dahlias and Pinching Dahlia Plants

• In order to get shorter plants with more flowers, pinch or “top” your Dahlias when they reach 12-16 inches tall.
• Top the plants with shears, scissors, or your fingers, taking care not to break the stem.
• After pruning your Dahlias, expect them to grow swiftly and produce more stems and foliage for future blooms.
• For even more blooms, keep pinching back the new growth. Pinching back a few of the forming buds will increase the size of the remaining flowers.
• The similar effect as pinching can be achieved by snipping the stems of your flowers.
• Keep deadheading as soon as the blooms fade so that the plant’s energy can be devoted to more blossoms rather than seed production.

You can encourage the growth of stems and leaves rather than flower buds by pinching or pruning back the dahlia stems. One stem is left alone in the film because it will generate a bud sooner than the cut ones, which will take longer to mature.

Plants that are bushier, stronger, and simpler to manage will take the place of lean, tall ones. One of the great advantages is that each plant will produce more flowers.

Dahlias for a Cutting Garden

Dahlias are ideal for a cutting garden because of their compact growth habit. There are more blossoms if you cut more often! Cut flowers frequently for bouquets when they are in full bloom. Cutting the flowers stimulates new growth and flowers, just as pinching does, keeping the dahlia healthy and blooming! Win, win, win.

However, despite the fact that pinching Dahlias increases their sturdiness, a support structure such as an obelisk, wire cage, or stake is still required.
