Types/Varieties of Dahlia Flowers
There are so many varieties of dahlia flowers. Some of them are listed below:
This type of dahlia flower consists of a single or one set of petals around the central or middle disc. The blooms or flowers are nearly about 10 cm in diameter.
The blooms or flowers are very small and consist of 2 or 3 rows and with somewhat pointed petals and they are slightly incurved by forming a cup around the central disc.
In this type, the flowers have a central disc as a dense dome-shaped of tubular florets surrounded by an outer ring of petals.
The flowers of this type somewhat resemble the singles, and they even as an additional ring of small petals called the collar, which is about half the length of outer petals.
Paeony flowered Dahlias:
This type consists of semi-double flowers and a few rows of petals surround a central disc. The blooms or flowers may be of large, medium, or small size.
The flowers of this type or variety are fully double in size, and the central disc of the flower is not visible until the blooms or flowers are aged. The petals are very flat and even broad with a blunt point.
These types of flowers have fully double flowers like decorative Dahlias. Petals in this type are very narrower and to be more pointed like cactus spines. Sometimes even petals tend to curve backward also.
Double show & fancy Dahlias:
The flowers in this group or type are also fully double; it is almost globular and had small central florets. The Margins of these petals are incurved, tubular, and blunt at the mouth of the flowers. The flowers are 10 cm.
These resemble precisely the double show and fancy Dahlias within the shape of bloom except that these are much smaller in size.
Dwarf bedding Dahlias:
The height of the plants during this group is between 30 and 60 cm which is far but regular Dahlia plant, but the formation of the flower may belong to any of the above groups.

Dahlias flowering plant usually likes rich, well-draining soil with plenty of organic matter. The soil pH should be around 6.5 it is fairly neutral. If you are planting your dahlia tubers in containers, you need to mix in a bit of garden soil for better moisture retention because the potting soil can dry out quickly and the tubers must have moist until they have sufficient roots.
Sunlight Requirement for Growing Dahlia Flowers At Home
This dahlia flower does very well when they have full sun; it needs at least six to eight hours a day. In hotter or warmer climates, they will do very better with a bit of shade in the peak afternoon hours when the sun is especially very hot and they can risk burning the plants.
Suitable Container or Pot for Growing Dahlia Flowers At Home
For most of the dahlias, you want a very large pot, though it needs not to be very deep. Many varieties of flowers will do very well in a 12- to 14-inches diameter pot and it should also be at least 12 inches deep. Also, you need to make sure that the pot has good drainage because the tubers will rot if left to sit in water.
When to Plant Dahlias?
You should not be too hurrying to plant; dahlia plants will struggle in cold soil. Ground temperature should reach 16°C. You need to wait until all danger of spring frost is past before planting. Some people start tubers indoors in containers or pot a month ahead to get a jump on the season. Medium to dwarf-sized dahlia plants will do very well in containers. You need to order dahlia tubers in early spring.
How to Plant Dahlias?
- You need to avoid using dahlia tubers that appear wrinkled or rotten. Pink buds also called “eyes” or a little bit of green growth are good signs for planting. You should not break or cut the individual tubers of dahlias.
- Dahlia plants can be planted 9 to 12 inches apart. The flowering types of smaller flowers, which are usually about 3 feet tall they should be spaced 2 feet apart. The taller and larger-flowered dahlias need to be spaced 3 feet apart. If you plant dahlias about 1 foot apart, they create a pleasant flowering hedge and can support one another.
- The planting hole of the plant should be slightly big than the root ball of the plant and you need some compost or sphagnum peat moss into the soil. mixing a handful of bonemeal into the planting hole will also help to grow.
- You need to dig a hole that needs to be about 6 to 8 inches deep inside. Then you need to set the tubers into it, with the growing points, or growing “eyes,” it should be facing up, and you need to cover it with 2 to 3 inches of soil. As the stem sprouts out, you need to fill it in with soil until it is at ground level.
- The tall and large-flowered plant will require support. At planting time you need to place stakes around plants and tie the stems to them as the plants grow.
- Dahlia plant starts blooming or flowering in about 8 weeks after planting, starting in mid-July.
- You should not water the tubers right after planting them; this can encourages rot. You need to wait until the sprouts have appeared above the soil to water.
- You should not bother about mulching the plants. The mulch may be very harboring slugs and dahlias like the sun on their roots.
Water Requirement for Growing Dahlia Flowers At Home
Especially young plants of dahlia plants do not need a ton of water to survive. Over-watering your plant poses more of a potential issue, as excessive water can cause the plant to rot. Because the roots of the dahlia plant are very close to the surface of the soil, a typical summer rainfall can usually sufficient. If your plant gets less than one inch of rain in seven days or a week, you need to plan to supplement with additional watering. However, with dahlias, it’s most important to never let the soil dry out. They’re not deep-rooted plants. Dry soil equal to a dry plant.
Required Temperature and Humidity for Growing Dahlia Flowers At Home
Timing is especially very important when it comes to planting and growing dahlia plants, as they will struggle to establish in cold soil. You need to wait until the final spring frost has passed and the ground temperatures have reached around 15 °C.
Additionally, dahlias like more humidity when being stored as tubers, but they don’t require additional humidity in their environment when growing in the spring and summer outdoors.
Fertilizing Dahlia Flowers At Home
Dahlias benefit more from a low-nitrogen liquid fertilizer such as a 5-10-10 or 10-20-20. You need to fertilize after sprouting and then every for 3 to 4 weeks from mid-summer until it reaches early Autumn. You should not over-fertilize, especially with nitrogen content, or you risk small or no flowers, weak tubers, or rot. Dahlias benefit greatly from being treated with fertilizer—the more food they get, the larger roots they’re going to grow, and subsequently the larger (and more numerous) their flowers are going to be. Whatever sort of fertilizer you select, search for one with a coffee nitrogen ratio, and do not fertilize after August.
Pinching, Disbudding, and Staking of Dahlia Flowers
When your plants are about 1 foot tall, you need to pinch out 3-4 inches of the growing center branch to need to encourage bushier plants and to increase stem count or stem length.
If you want or wish to grow large flowers then try disbudding which means you need to remove the 2 smaller buds next to the central one in the flower cluster. This will allow the plant to put all of its energy into fewer but considerably very larger flowers.
For the taller dahlia plants, you need to insert stakes at planting time. You need to pinch, disbranch, and disbud, and deadhead moderately to produce a new showy display for 3 months or more.
Summer and Fall Care for Dahlias
You need to fertilize the dahlia plant monthly with a water-soluble, organic fertilizer that’s formulated for flowers. You need to avoid using a high-nitrogen fertilizer, or you may get lots of green growth with little flowering. You need to mulch with straw or shredded bark to keep weeds to retain moisture. You need to water regularly, especially in dry periods.
Overwintering for Dahlias
Dahlias are tender annuals, but you’ll overwinter them pretty easily. In fall, after the primary frost has blackened the foliage, stop about 2 to 4 inches of top growth, and punctiliously dig tubers without damaging them. Allow tubers to dry for a couple of days during a frost-free location, out of direct sunlight. Once dried, you need to remove the excess soil, leaving 1 to 2 inches of stem. Store each clump of tubers during a ventilated box or basket.

Common Dahlia Plant Problems
No matter how experienced you’re as a gardener, some issues will arise together with your plants. Those amazing flowers referred to as dahlias are not any exception. Among the foremost common dahlia, diseases are those caused by fungi, like mildew and grey mold. Dahlia flower pests tend to reflect the sap drinking forms but also can encompass leaf eaters like a good array of caterpillars and larvae. Knowing what to observe for is half the battle to keep your prized plants healthy and delightful. You’ll have little chance of giant bunches of flowers if your tubers are scrawny, moldy, or rotting. Start with healthy tubers first. The primary signs of trouble in your plants are often even as they sprout and develop leaves. It’s common to seek out new leaves completely chewed, lacy, and barely still there. The culprits are usually caterpillars or some sort of larvae. These prey on leaf tissue and make Swiss cheese of the foliage, diminishing the plant’s ability to intake solar power. Hand-picking could also be the answer to beating these sorts of problems with dahlia. Fungal issues like mildew are another universal complaint. Avoid overhead watering and use a horticultural fungicide.
Dahlia Plant Diseases
The diseases may include:
- Stem rot – Stem rot will occur when dahlias are growing in heavy and poorly drained, wet soil. Search for a white ring within the soil around the stem. The rot will sneak in and kill the stem and advance down into the soil to kill the tubers.
- Mosaic virus – Mosaic virus may dwarf plants and also distorts leaves. You need to destroy the plant because there is no cure.
- Botrytis – Botrytis blight is nearly as bad and causes buds to rot and covers the plant with powdery gray mold. Remove any affected part and destroy it.
- Aster yellows – Leafhoppers, they are commonly found on plants, are the main vector for Aster yellows, it is a disease where leaf-like tissue forms on the plant where you should be getting flower buds. Plants are sadly a loss.
- Viral issues – diseases with the dahlia plant also include verticillium wilt and necrotic spot virus. Infected soil causes the former and leaves to become black, brown, or greenish-brown.
Numerous insect pests find dahlias delicious. additionally to the caterpillars and larvae, sucking insects are likely to be the foremost important issue with the most widespread offenders being: Aphids, Thrips, Mites, Leafhoppers, these are relatively very tiny pests and they have a habit of sucking sap from the plant can diminish its health, cause stunting and distorted plant parts and even transmit disease. Systemic fertilizers may offer some protection if applied early within the season. Slugs, snails, and cutworms produce bigger damage that’s visually obvious and reduces plant health. Hunt in the dark with a flashlight and use the “squish” method of pest control for cutworms. Slugs and snails could also be controlled with diatomite or slug baits.
You need to cut the dahlia stems when the central flowers of the plant are fully opened and you need to cut them in the morning when the plants are full of water, which will give you the longest-lasting cut flowers. You need to bring a bucket full of water. Then, you need to take a long section of the stem. The stems are sturdy and can make great arrangements.
