How to grow a dahlia plant?

To grow a dahlia plant, all you need is ONE tuber with ONE “eye”/sprout. A viable tuber needs to have an “Eye”, a neck and a body. If the “tail” is too long, you can cut off up to 3/4 of the tail and the tuber is still viable. For new growers, locating the “eye” can be tricky at first, but with practice you’ll be able to spot them.

How many dahlias will one tuber produce?

One tuber = one dahlia plant = many blooms per plant. The number of blooms per plant varies, depending on the variety (the smaller the bloom, the more you tend to get per plant). Some people will take cuttings from their dahlia tubers (do so at your own risk). Learn more about dahlia cuttings, here.

Will dried out dahlia tubers grow?

1. How are dahlias grown?

Dahlias are grown from tubers, which are “bulbs” that grow underground. Dahlia tubers are a lot like potatoes - you plant one tuber and end up with many more at the end of the season. Dahlias CAN be grown from seed, but dahlias grown from seed are not genetically stable and often turn out to be “duds”.

2. Do all tubers look the same? Does the size of the tuber matter?

NO!!!!! There are thousands of different types of dahlias…. and each one grows it’s tubers a little differently. There is a shocking amount of variety in shape and size! Some are tiny and slim, like a pencil. Some are short and stubby, with little to no neck. Some are huge and chunky.

3. My tubers look a little shriveled. Will they still grow?

In most cases, YES. Remember, as long as the tuber has an eye, it will grow.

When To Plant Dahlias

To get started, you need to know when to safely plant dahlias outside. This varies from growing zone to growing zone. While it can be tempting to get an early start on growing dahlias, your dahlia tubers should not be planted until the ground has warmed and all dangers of frost have passed.

Where to Plant Dahlia Tubers

This is where I grew dahlia tubers in 2019. I experimented using a weed barrier cloth around the dahlia plants. I would not recommend this for dahlias.

Can Dahlias Grow In Containers

Growing dahlias in containers is typically not recommended unless you are growing dwarf varieties.

How Far Apart Do You Plant Dahlia Tubers

Dahlia tubers laying in the ground, ready to be covered up with soil. The ideal planting distance for dahlias is 12-18 inches apart.

How Deep To Plant Dahlias

When it’s time to plant your dahlias, begin by making a hole that is 4-6 inches deep. Once you dig the hole, mix in a small handful of bone meal. This will provide important nourishments for your growing dahlia plant.

When Should I Water My Dahlia Plants

Dahlia plants that have recently emerged from the ground. These dahlias have their first true set of leaves and can now be safely watered.

Time To Get Growing Your Own Dahlias

Alright, it’s time to get started growing your own dahlias for your cutting garden! Hopefully after reading this post, you feel more prepared and confident in planting your dahlia tubers. Below you’ll find a FREE printable step by step guide that I’ve created to help you plant your dahlia tubers.

1. I heard that dahlias are hard to grow. Is that true?

Yes. No. Maybe? While I would say they are NOT difficult to grow, they ARE one of the most labor intensive flowers grown for cutting. So, yes, they are "easy to grow" but require some special care.

2. What is a "tuber"? Is that like a "bulb"?

Dahlia tubers are sometimes called a "bulb", but they are technically a tuber, similar to a potato. Similar to a potato, the tuber sends up a shoot that becomes the plant, which produces leaves and flowers. Underground, the tubers multiply each year (again, like a potato).

3. Pinching? What does that mean?

If you want your plant to produce multiple blooms, you must "pinch" or cut back the plant early on, when it has reached 12-16" tall. Find the center stalk, count down about 1-2 sets of leaves and make a cut with clean clippers, removing the top inch or two of the center stalk.

4. Do I need to stake dahlias?

Yes, most varieties will need to be staked, otherwise the wind may flatten and ruin the whole plant. Gently tie the plant to a sturdy wooden or metal stake. A tomato cage would also work!

6. You said in the video that the tubers multiply each year. Does that mean I'll be able to plant even MORE of them next year?

YES! If you dig up the tubers in the fall, properly store them and divide them, you can easily triple or quadruple your stock in 1 year. Once you factor that into the price of buying a tuber, they don't seem so expensive anymore!

7. So... do I HAVE to dig up the tubers every fall? What do I do with them?

No, you don't HAVE to... but then you will have to by new tubers each spring, which gets expensive!

8. Ummm... how do I divide them? That sounds hard

I'll admit it takes practice and you will make a lot of mistakes at first, but it gets easier with time.

Can You Divide Dahlias?

I love our state fair where there is an entire pavilion filled with every size, color, shape, and style of dahlia you could imagine. This is a magical place overflowing with promise and unique beauty. Dahlias are easy to grow in well-drained soil, full sun, and deeply tilled earth.

When to Divide Dahlia Tubers

Dahlia growers know better than to take a chance and leave the tubers in the ground over winter. Excess moisture may rot the roots and a good hard freeze will simply kill them. If you dig them up in spring, you may find a mass of mushy, rotten tubers which will not produce.

How to Divide Dahlia Clumps

Lifting the clump of roots carefully will prevent any mechanical injury which will damage the tubers. This is done in fall, but wait to divide the roots. Find the previous year’s mother tuber and get rid of her. Her energy is mostly spent and she will not be a good plant.

1. Wait Two Weeks After Frost to Harvest Dahlia Tubers

It’s ideal to harvest and store dahlia tubers that have gone into dormancy, so they’re not shocked by the transition of summer growth to winter storage. Two weeks after your first frost is the ideal time to harvest them: they’re well into dormancy yet haven’t been harmed by the cold.

2. Trim Back Your Dahlia Stems

Just before digging your tubers, trim each stem back most of the way to the ground. We like to leave five to six inches of the main stem so we have a ‘handle’ to hold as we lift and rinse them. Dahlia stems, like straws, are hollow, making them quickly susceptible to rot.

3. Dig Your Dahlias

If you have a choice (and often you don’t), dig your dahlias when it’s nice and warm (at least in a relative sense), when the soil is not totally wet. Since it’s deep into fall when we harvest here in Zone 5, the ground is often wetter than we’d like. But the soil isn’t likely to dry out until May, so we do the best we can.

4. Rinse Your Dahlia Tubers

Pretend you’re washing fresh eggs, delicate and fragile. Protecting the necks of each tuber is paramount. That being said, your garden hose on ‘jet’ is quite ideal to rinse them. Resist shaking them and handle them as little as possible.

5. Divide Your Dahlias

Once your dahlias are thoroughly rinsed, bring them into a warm, well-lit workspace to divide them. Here are the tools I have on-hand:

6. Dust Your Dahlias with Sulfur

Once we divide all our tubers of a particular variety, we dip them into a bucket of powdered sulfur and vermiculite, providing an organic antifungal coat to prevent rot in storage. A spare dusting is quite ideal.

7. Pack them in Peat Moss

Tuck each tuber in a box with peat moss. It’s important that the box be fairly air-tight; we line our open-sided bins with plastic to ensure there is minimal moisture loss. Next, put down a one-inch layer of peat moss.

What Are Dahlia Tubers?

You might think of a tuber as a type of seed or root, but they do have some key differences. Many plants and vegetables grow from tubers including the dahlia. A tuber is a swollen underground part of the stem which contains all of the essential nutrients required for the plant to grow.

How To Tell If Dahlia Tubers Are Dead

Dahlia tubers can be dead for a variety of reasons including insect attack, dry soil conditions, and over-watering and if a dahlia tuber is rotten, it will not grow.

How to Save Rotten Dahlia Tubers

In many cases, a rotten dahlia tuber won’t be any good and you’ll need to discard it. However, it isn’t always bad news as there are times that the rot won’t have spread too far, and the tuber can be salvaged and used to grow a beautiful plant.

How to Prevent Dahlia Tuber Rot

Dahlia tubers do not cope with being waterlogged and this can cause them to rot so you will want to ensure that they are planted in well-draining soil. If your garden is prone to waterlogging, you may want to lift your tubers and store them for winter.

Conclusion

Dahlia tubers are starchy bodies that contain the nutrients that the plant needs in its first stages of growth. They come in different shapes and sizes but there may be some problems you face when planting them. One of the most common issues is dahlia rot but how can you tell if dahlia tubers are dead?

Frequently Asked Questions

Yes, Dahlia’s can be left in the ground over winter, but they do not like to be waterlogged, nor will they cope with a heavy frost. If you wish to leave your Dahlia’s in the ground, ensure the soil is well-draining and mulch with straw.
