Dahlias are a great addition to any garden. They come in a variety of colors and sizes, from small flowers less than an inch across to blooms as large as dinner plates. In general, dahlias get taller as their flowers get larger. The tallest varieties can reach heights of over six feet! If you want your dahlia plants to thrive for years, it’s important that you cut them back after they’ve finished blooming. This will help ensure that they get enough light during the winter months and will also make them more attractive come springtime.
To keep your dahlias in good condition, care for them throughout the entire season. Dahlias grow from bulbs. The bulbs are fragile and need to be protected from the elements, but their leaves and stems can tolerate heat, drought, and harsh sunlight. Before planting dahlia bulbs, make sure to till the soil thoroughly and add compost or fertilizer. This is important for drainage as well as food for the plants. When you plant bulbs, place them vertically in the ground so that no more than half of the bulb is exposed above ground. Plant several bulbs together in groups of 5-6 bulbs with 3-4 inches between each bulb. Make sure that each bulb receives plenty of sunlight and nutrients by digging large holes before planting.
Watering dahlia plants correctly will help them thrive when they are blooming and when they are dormant. Potted plants need frequent watering during the growing season, while outdoor plants generally only need water during a drought or if there has been no rain for several days. The first step to success with your dahlia bulbs is planting them at least six weeks before your first frost date. This will give them time to grow roots before winter.
Once your Dahlias have flowered, you must properly care for them. Follow these tips to keep your Dahlias looking beautiful. Learn more about deadheading, weed control, and fertilizing.

Deadheading dahlias
It is common to deadhead dahlias after they bloom to encourage new flowers. By cutting off the dead petals and seeds of the plant’s fading flowers, you can encourage the dahlia to continue to bloom throughout the growing season. Deadheaded flowers produce no seeds, and so the plant will conserve energy to make new flowers. As a bonus, you’ll save money by not having to purchase new plants!
To deadhead dahlias, know the difference between a spent flower and a young bud. You can tell a spent bloom by its shape: it is narrow and pointed, while the fresh bud is round and compact. Once you’ve identified which one is yours, you can proceed to deadhead the dahlia. If you’re still unsure, check the blooms on your dahlias for signs of disease and insects.
The flowering time of a dahlia depends on how old it is. You should always remove the dead flowers from your plants, even if they resemble new buds. The process of deadheading dahlias encourages new growth and ensures that your dahlias stay healthy. In addition, deadheading dahlias will help to maintain the overall appearance of your garden. It will also show your pride in your garden.
When you want to save seed from your dahlias, wait until the plant is fully mature. Then, cut off the spent flowers and dry the pods indoors for four to six weeks. You can then clean the seed heads and store them in plastic bags or packets until they’re ready to be planted. Sow the seeds in early spring. If you wish to harvest more than you need, simply replant them in the spring.
Planting dahlias in full sun
When planting dahlias, make sure they receive plenty of sunlight. This flower needs about five hours of sunlight per day to bloom at its peak. They also prefer a humid, temperate climate. If you have a very hot or dry climate, dahlias will not grow well there. However, if you have a sunny garden, dahlias will be a beautiful addition to your landscape.
Tubers of dahlias can overwinter in the ground during mild winters. However, they should be dug up and divided every year to avoid clumping and producing fewer flowers. Digging up and dividing tubers will also keep them healthy and make them easy to propagate. Make sure not to cut the tuber’s neck, as this will break the connection between the future eyes and the tuber.
Dahlias are tender annuals that can be overwintered. Cut the flowering stems after the first frost. If you don’t plan to plant them right away, you can overwinter them indoors. Make sure the bulbs are stored out of the direct sunlight for a few days to acclimatize to the outdoor environment. After they have grown a foot or two, you can transplant them in the ground and enjoy their beauty for a long time.
To plant Dahlias in full sun, make sure they’re growing in soil with at least a foot of space between the tuber and the ground. Once the tuber is planted, it’s important to wait a couple of days before watering to keep the soil moist. When the roots are planted, they will sprout new stems. You can also stake the tuber if you want to encourage them to grow.
Fertilizing dahlias
After the flowers have faded, it is time to fertilize your dahlia plants with a balanced liquid fertilizer. This will promote healthy leaf development and encourage the plant to produce more flowers. In order to ensure that your dahlia plants are healthy, don’t fertilize them with fish emulsion during their flowering period. It is not the best fertilizer for dahlias.
To give your dahlias the best chance to bloom, plant the tubers at least three weeks before the eyes develop. Ideally, dahlia tubers are planted at a depth of 12 inches. For a more uniform growth, you can mix in some compost or all-purpose granular fertilizer before planting the tubers. After that, you can plant your dahlia tubers and backfill the hole to make sure that they’re well-established.
You don’t need to fertilize your dahlia plants until they’re three to four inches tall. This will protect the feeder roots from excessive amounts of nitrogen. Dahlias need a balanced fertilizer with less nitrogen than other plants, so use 6-24-24 fertilizer instead. You can start fertilizing your dahlia plants in a greenhouse or cultivate them in the ground before planting.
Water your dahlias twice a week or more. Depending on the temperature and soil composition of your garden, you can use a spray to water them once a week. A good all-purpose spray is Monterey. For fertilizer, use Ortho, Bayer, or Monterey. They all have excellent ingredients and are inexpensive enough for any gardener to use. If you’re unsure, try a soaker hose.
Maintaining weeds around dahlia plants
There are several ways to maintain weeds around dahlias, including pulling them before they grow. If the soil is too wet, they can develop powdery mildew. Other pests and diseases can affect dahlias, too. Japanese beetles, earwigs, and aphids can also attack them. Insects, like caterpillars, can also cause damage to the tubers.
If you want your dahlias to bloom properly, tagging them with their variety name will help you identify them. You should also fertilize your dahlia plants once or twice a month with a water-soluble organic fertilizer. High-nitrogen fertilizers can cause green growth without flowering. If you choose to fertilize your dahlias, make sure to use organic fertilizer high in phosphorus. You can also use compost to improve the soil’s moisture content. And don’t forget to deadhead dead flowers to encourage more blooms.
While dahlias are hardy plants that require little care, you should make sure you prepare the soil for them before planting them. Ideally, you should use well-rotted compost or sand, but avoid using fresh or manure, which may disturb their roots. Do not use weed preventers or chemical weed control when fertilizing dahlias. Using a seed-warming mat will help maintain the soil temperature around your plant. If you have a garden that receives lots of sunlight, you can transfer it to the outdoors. Once the soil outside is 60 degrees Fahrenheit, dahlias are ready to move outdoors.
In addition to controlling weeds, dahlias attract pests. Slugs and earwigs will attack your dahlias when they are young, but they won’t bother mature dahlia foliage. Deer, however, are another problem you can face. You can easily control this pest problem by keeping weeds away from your dahlia plants.
