How do you dry a dahlia flower?
Carefully pour silica gel over your flowers until there's at least an inch or more covering your blooms. Cover your container with a lid or saran wrap to make it airtight and leave it alone in a cool, dark place for 7 days. When it's time, remove your flowers very carefully as the petals will be dry and crisp.
In order to maximize their relatively short 3 to 4 day vase life, warm or hot tap water is ideal. I've found that dropping them in a vase of hot water and letting it cool to room temperature can extend their vase life up to 2 to 3 days.
Preheat your oven to its lowest heat setting and line a cookie sheet with parchment or wax paper. Lay out your flowers and make sure they're not overlapping each other. Place them in the oven and leave the door cracked so moisture can evaporate. Flowers will typically need eight to twelve hours to dry completely.
To help flowers retain their color during the drying process, make sure to remove them from sunlight as soon as they're cut. Hang flowers individually or rubber-band stems together to hang a bouquet. Find a dark, dry area with good circulation, such as an attic or unused closet.

Air drying works well for smaller flowers, but the process often shrivels large, fragile blooms beyond recognition. Roses, peonies, dahlias, sunflowers, lilacs, zinnias, hyacinths, and daffodils fare much better when they are dried with a desiccant. Silica gel is one of the easiest and most reliable desiccants to use.
After you've harvested dahlia flowers, make a fresh horizontal cut at the bottom of the stem and place the cut ends in about 2 to 3 inches of very hot (not quite boiling) water. Let the stems stay in the water for at least one hour. This hot-water treatment conditions the stems so the blooms will last four to six days.
Dahlias can bloom for four months if you prune them properly. In some locations, you might even get them to last a few more weeks longer than that (but they will not survive a hard freeze, so you will need to take them inside before that happens).

There you have it: Dahlias without water, and a wonderful way to decorate a table. Vases need not apply.

Can you use salt to dry flowers?
Whether drying flowers for craft projects or purely sentimental reasons, maintaining the color of the blooms is key. Many flower preservation methods include salt because salt maintains flowers' vibrant colors throughout the drying process.
You can also use hairspray to preserve fragile dried flowers—especially bouquets with particular sentimental value. They will hold up better when moved around, and colors will fade less over time.
Hanging the flowers upside down means they should maintain their upright structure with the stems remaining rigid. Best for: Lavender, larkspur, achillea, roses, cornflower, strawflower, nigella, hydrangea and most foliage.
For the most part pressed flowers are able to maintain their natural color for a very long time, but eventually some amount of fading is inevitable (typically after 5-7 years on average). Some may begin to show fading sooner, while others may last longer.
When your petals are crisp, they are fully dried. The drying process can take anywhere from two to four weeks but may take longer depending on the size of your bundles.
Start by gathering your flowers in small bunches by the stem and secure them with a piece of string or rubber band. I find the easiest way is with a elastic band. Hang the flowers upside down in a dark dry place that receives good air circulation. Make sure that your bunches are not too close together.
Cut off the foliage and carefully dig out the tubers. Brush off excess dirt and let the tubers dry for a few days. If possible, hang them upside down when drying them so that moisture can leach out of them. Drying is important to saving dahlias over winter and preventing them from rotting.
Place the cover on the airtight container. Check you flowers everyday until they reach the point of being dry, but not brittle. If you leave the flowers in the silica gel too long they will become brittle and shatter like glass when they are removed.
Today, dahlia flowers symbolize beauty, commitment, and kindness. They're also tied to steadfastness, due to their ability to bloom after many other flowers have died.
Dahlias are one of the best garden plants for growing for use as cut flowers. Not only do they have an outstanding vase life, but they provide a season-long supply of spectacular blooms from mid summer right through to the first frosts.
Does cutting dahlias encourage more flowers?
By pinching or cutting back the dahlia stems you are stimulating the plants energy to producing more stems and leaves instead of flower buds.

Dahlias will flower from midsummer through till the autumn and the first frosts providing a long flowering season. Dahlias are like a rich soil which is well drained and lots of sun.
It's easy to understand why: This symmetrical flower makes a big impact and can be far less expensive than other popular wedding flowers. Why? The dahlias affordability is in large part due to its comparatively long growing season.
Pinch the tips off of dahlias once they reach 16 in (41 cm). When the dahlia first starts growing, it will develop 4 sets of leaves. Pinching off the top of the plant above the fourth set of leaves will encourage branching, resulting in a fuller plant and therefore more flowers.
