Share

Dahlias are among the gardeners’ most popular flowers as they’re relatively simple to plant and can provide an excellent reward when they start to bloom. They are low-maintenance and look stunning when planted in the yard in cut flower arrangements. This is a quick guide to teach you on how to grow and take care for dahlias.

Why should you grow dahlias?

The pretty flowers are widespread in gardens due to their rugged appearance, which everybody loves. Furthermore, they can beautify your yard for a lengthy time. They bloom at the time of the summer’s beginning. They last until fall and maybe bloom when spring’s first frost season takes over. In certain regions, they could even last through winter, but this typically occurs when it’s sufficiently warm.

Although they may not endure as long, the possibility of growing dahlias in cooler climates is also feasible. You can give them the chance to succeed by planting them indoors first, then taking extra care of the plants. Create a garden full of stunning flowers if you can learn to grow dahlias wherever possible.

How to grow dahlias

Once you’ve bought the plants, you need to prepare to plant. Dahlias require little maintenance, and they are easy to grow. Therefore, following the proper steps will guarantee an efficient and healthy plantation. Here’s what you have to be aware of and what you have to remember when plantation.

Prepare the holes for planting

Dig holes in the ground where you’ll place the flower. If you are learning to grow dahlias, be sure you know the correct treatment for every kind. Because they come in various sizes, each requires different spacing. The tall variety can produce huge flowers too, so you must plant them 3 feet from one another. The dahlias of medium size should be just two feet from one another. On the other hand, the smaller ones can spread between 9-12 inches from one another. But, that’s not all you should be aware of about the holes for planting.

You must make sure that you dig large enough to fit the tubers. Take measurements of the tubers before digging to ensure that the holes are a little larger. To ensure that the plants are growing, add some compost to them. It will provide dahlias with that needed boost.

Choose the spot

The spot where you plant your dahlias is crucial for their development. Dahlias require between 6 and 8 hours of sunlight during the day. Therefore, choosing a location where the plants will receive direct sunlight is essential. Be sure to ensure that the area is shielded from winds. But, depending on your site, you may require treating the flowers differently.

For instance, if you reside in the South, where the temperatures in summer can reach incredibly high temperatures, Dahlias may be a little afflicted. They can’t withstand extreme heat, and it is best to shield them from direct sunlight during this time.

In colder regions, it is difficult for them to endure the winter. In some areas, it may be sufficient to spread a layer of mulch that keeps the soil cool.

Choose the right moment for planting

The time when you plant dahlias is crucial. They do not thrive in cold soil, so be patient until your weather becomes warm enough. It is essential to ensure that there isn’t another frost falling over your plants. So, it could be the perfect month for your gardening needs.

Choose the soil

If you wish your dahlias to be healthy and robust, you must ensure that the soil they are growing will suit the plants. Your soil’s pH must be acidic, somewhere between 6.5 to 7. It is also necessary to have a location with a sound drainage system, which you could create. If your ground is heavy for drainage properly, You can mix manure, sand or moss to make it more pliable.

Planting

When selecting the tubers, you’ll take note of their appearance. They shouldn’t be old-fashioned since this could lower your chances of having concrete plants. If you see the arrival of green growth on them, this suggests they’re suitable for growing. Don’t apply the same technique you do when planting potatoes.

It is not recommended to cut the tubers and insert them into the holes without harm. Set them with the growth upwards at 6-8 inches. This will enable the changes to grow beyond the soil.

Tips

  • Beware of planting dahlia tubers which appear rotten or wrinkled. The pink “eyes” (buds) or some growing green are excellent indicators.
  • The best way to produce is with giant dahlias and others grown exclusively for cut flowers in a designated area where they are unaffected by the competition of other plants. Plant tubers in rows that are spaced three feet apart. Planting dahlias 1 inch apart, they will make an attractive flowering hedge that can support one another.
  • Plant medium-to-low-dahlias, generally around 3 feet tall, along with other summer flowers. Place them two feet from each other.
  • Plant the tiniest bedding dahlias grown from seeds 9-12 inches apart.
  • For planting the tuberous, begin by digging a 6-to 8-inch-deep hole.
  • Place a tuber in the hole, keeping the growing points, also known as “eyes,” facing up.
  • Don’t cut or break each dahlia tube (as you would with potato tubers).
  • The tuber should be covered with two to three inches of earth. (Some suggest that 1 inch is sufficient.)
  • When the stem begins to sprout and grow, fill the soil with it until it is at ground level.
  • Don’t water the tubers after planting. This can cause the onset of rot. The sprouts should wait until they are above the soil and give water.
  • The hole for planting must be slightly larger than the roots ball of the plant. It should also incorporate compost or sphagnum peat into the soil. It can also help to mix a small amount of bonemeal in the planting hole. If not, don’t fertilize the planting area until after the plant is established.

How to care for dahlias

After you have planted the plants, you must let them develop. They’ll need some care to ensure that they grow large and beautiful.

Fertilizing

Thirty days after planting the dahlias, it’s time to apply fertilizer with a small amount of nitrogen. When the plants begin to grow, it is recommended to do the fertilization process only every month. Be sure to not overdo it and choose an organic fertilizer that isn’t water-soluble.

Watering

Wait until the first signs of sprouts emerge above the ground before irrigation the dahlias. If you water them before this, it could cause the tuber to turn brown. Once you have confirmed that the germination is successful, it is possible to set up the routine of watering two times every week. Make sure you use a large amount of water, particularly in the summer heat and hot days.

Staking

This only applies to taller species. However, it’s crucial to be aware of this as you learn how to cultivate dahlias. Once the dahlias start to grow, place stakes around them and connect the stems to these stakes. This step is essential because the stems aren’t strong enough to support their weight, and the flower’s weight will increase should they become several feet high.

Protection from pests

The most prevalent insects that attack dahlias include leafhoppers and aphids. You can remove them with an insect-specific soap as well as isopropyl alcohol. Spider mites may occur in hot weather but are less challenging to eliminate. One splash of cool water can stop them from appearing.

Powdery mildew could be an illness that can attack plants. If this is the case, you’ll require the use of an anti-fungal. Most often, this kind of illness is caused by plants that aren’t adequately aerated, and you should provide them with plenty of space. Another fungus could start taking over the stems of the plant when the plant is overwatered.

You’ll have to remove the entire plant to eradicate the disease. When you replant, be mindful regarding the drainage of the soil as well as the timing of the watering. Mulch can help keep weeds as well as other diseases at bay. Therefore, you may use this option too. But, be sure that you do not apply it directly to the stems.

Conclusion

The art of growing dahlias is essential for any gardener. They are as popular as roses and tomatoes and create a beautiful visual effect in your backyard. They come in various dimensions and colors, so it’s almost impossible not to find at least one that you like. So long as you ensure your plant gets the sunlight it requires and doesn’t get frozen during the winter months, the garden will appear like a dazzling color paradise of dahlias.
