Dahlias are a beautiful and popular seasonal flower, and preparing them for planting is an easy process that can be done by gardeners of any experience level. Dahlias will generally be available for purchase from the end of June through August.

Preparing dahlias for planting depends on your geographic location and local climate. In colder climates, dahlia tubers should be stored in the refrigerator for about six weeks prior to planting. In warmer climates, the tubers should be planted immediately after purchase or harvested from their previous location.

If you are storing the tubers before planting, pack them in a box full of vermiculite and place them in a refrigerator set at 40 degrees Fahrenheit. The idea is to keep them cold enough to be dormant, but not so cold that they freeze.

When you’re ready to plant them outdoors, select an area with good soil drainage and full sun. If you’re making a new bed, it’s best to prepare the ground in the autumn before planting. Mix organic matter such as compost into the soil to improve its quality. Add a low-nitrogen fertilizer just before planting to encourage tuber growth.

Dahlias do not like to have their roots disturbed; they grow better if they are transplanted while still small or started from seed indoors and planted out later on when they are large enough.

How To Prepare Dahlias For Planting

After the last frost, cut down the stalks of your dahlia plants to the ground. Cover them with 10″ to 12″ of mulch, such as grass clippings, leaves, straw, or compost. Dig out the tubers in March and dry them for 3-5 days. Replant the tubers during the appropriate planting time in your area. Learn more about fertilizing and pest control here.

Identifying dahlia eyes

The first step in identifying a dahlia is to recognize its ‘eyes’. Dahlias have a series of eyes on the tuber neck, where they sprout shoots. It’s hard to tell which of these is a viable tuber without a magnifying glass, so practice can make perfect. Here are some tips to recognize dahlia eyes:

Identifying the eyes of dahlia can be difficult, but fortunately, the process is easy once you know what to look for. Dahlia tubers contain everything a dahlia needs to grow. If they are missing these parts, the plant will be unable to grow. If you can’t identify the eyes, you can simply cut off the tuber and store it until spring.

If you are unsure about the eyes of a dahlia, check the tuber for signs of rot or driedness. A dry tuber may be viable but a rotted one will not grow. If you’re unsure about the eyes of a dahlia, feel the tuber with your hands. If it feels moist or dry, it’s probably fine. Otherwise, it’s time to move on to another dahlia.

The eyes of dahlia are located where the tuber joins the growing parts of the previous year’s growth. Identifying the eyes of dahlia is essential for proper identification and care. You’ll want to label these parts so you can be sure you’ve planted the right variety. If you don’t, the tuber may have rotted stems and won’t survive the transplant.

Dahlia tubers are grouped according to their color and shape. Many dahlia varieties have overlapping or curled petals. Some have an inner ring of shorter petals that surround the disc. Pompon dahlias, which are shaped like balls, have double flowers. They are round or blunt florets. Identifying dahlia eyes when planting, will make the process much easier!


There are several reasons for fertilizing your dahlias before planting. High nitrogen fertilizers tend to weaken the stems, encourage green biomass, and have little impact on bloom formation. Non-nitrogenous fertilizers, such as P & K, increase blooms and strengthen stems. Lastly, organic fertilizers improve soil quality. If you are planting dahlias in a pot, use half a cup of organic fertilizer in the topsoil four to eight weeks before planting.

You can also determine whether your dahlias need a specific type of fertilizer by performing a soil test. The level of nitrogen will vary depending on the soil type you have. Loamy soil drains away nitrogen quickly, while clay retains nutrients better. If your soil contains little to no nitrogen, you may need to feed your plants with more nitrogen each time. However, if you don’t have any soil tests yet, it’s best to consult your local garden center to get an exact recommendation for your dahlias.

When choosing a fertilizer, check the American Dahlia Society’s recommendations for your soil type and pH. The correct balance of nitrogen and potassium will help your dahlia grow strongly and produce large flowers. However, excessive nitrogen can cause poor growth and low-quality tubers. Instead, use a fertilizer with a balanced NPK ratio. If you’re using a liquid fertilizer, use a small amount of it to start, and stop after the first flowers bloom.

A small amount of plant food per square foot is recommended for Dahlias. Half a cup should be applied around the tubers two feet apart and lightly worked into the soil. Watering it will allow the plant food to seep down into the soil, without burning the surface roots. Fertilizing Dahlias every seven to fourteen days after planting the tubers is the best way to ensure a healthy and abundant flowering plant.

In addition to choosing the right formula, make sure to follow the application instructions on the container. If you choose a liquid plant food, you should spray it onto the plants using a sprayer. If you prefer solid plant food, spread it over the roots and main shoot of the plant. When the plant reaches four feet in height, stop fertilizing it and let it bloom naturally. You’ll see a marked improvement in the flowers and leaves of your plants.


Store Dahlias indoors or outdoors in a cool, dark place to maintain optimal growth. The ideal storage temperature is between 40 and 50 degrees Fahrenheit. When storing dahlia tubers indoors, spritz them occasionally with water. Discard any tubers that have mold or rot before spreading them. You can store your dahlia tubers in paper bags or milk crates.

To store dahlia tubers, clean them thoroughly. You can either use a garden hose or a brush. If you want your tubers to remain as clean as possible, use the hose or brush gently. After washing, dry thoroughly. You will want to label the tubers before freezing, as different varieties need separate storage. In this way, you’ll be able to identify and replant them in your garden as soon as spring arrives.

Store dahlia tubers for a long time. Dahlias are not ready for transplanting until late in the growing season, so the longer you can leave them in the ground, the better. If you live in a climate with mild winters, you don’t need to dig up your dahlia tubers until spring. If you don’t plan on planting them until late in the season, they may develop weak stems and smaller blooms.

The best time to dig up your dahlias for planting is during late fall or early winter. Digging up the tubers is best done when they’re just a few inches above the ground. Using a sharp spade, don’t dig too deep into the tubers. Start digging at about 12 inches from the stem. This will ensure that you don’t damage the tubers. Just make sure to label the tubers.

If you’re storing dahlia tubers for winter, you should clean them before putting them in storage. Dust and soil can damage the tubers during storage. Shaking off the soil will help you avoid the moisture problem. Another way to release excess moisture is to hang your dahlia tubers in a dry area. Make sure the location is well-ventilated and away from extreme temperatures.

Pest control

If you’ve been having trouble with insects attacking your Dahlias, you may want to use an organic insecticide to keep them away. This simple solution contains soap and neem oil, which is effective in killing insects and stopping them from spreading. However, it’s not practical for home gardeners, and it won’t work as well as an insecticide because beneficial insects can also be killed by the same treatment.

To get rid of these pesky critters, you should use a variety of methods for controlling pests. Some of the most effective and eco-friendly methods involve the use of water and organic Neem oil solutions. In addition to organic remedies, you can also use beneficial Lady Bugs, which are beneficial to the health of your Dahlias and prevent thrips from returning. Fortunately, they are not hard to find.

Unlike insects, mites are difficult to kill because they reproduce and mutate faster than insects. Because of this, chemical insecticides can be difficult to use, and the pests you’re trying to kill can become resistant to them. You’ll need to rotate chemical classes to prevent the use of one pesticide too often. Neem oil is the best option for controlling mites and other pests. The oil helps smother eggs and the early larval stages of insects. It’s safe to use horticultural oil two or three times a year, but remember that overuse of this product can cause resistance to other pesticides and fungus.

Before planting Dahlias, be sure to secure them in a pot. Be sure to water them regularly as they will need more water than smaller varieties. Also, be sure to secure their stems to support them as they grow. If you don’t use this technique, the dahlias may wither without the ability to bloom. You should also make sure they are not planted in an area that has been chemically treated.

When applying a pesticide to your Dahlias, you must ensure that it is effective in killing both small and large mites. The most common insecticide used to kill mites in your garden is Pylon, which is highly effective when applied around showtime. It does not damage the blooms, but it is best to use this spray during show season. Repeated applications may cause the mites to become resistant to the chemical and may lead to the growth of new populations.

In conclusion,

Dahlias are great for flower beds and borders. Plant them in well-drained soil and full sun. They can take up to 3 months to bloom, so don’t be discouraged if you don’t see flowers right away.

You will want to plant them in containers placed outdoors when the weather begins to warm. You can plant them in the ground after the threat of frost has passed.
