When To Buy Dahlia Bulbs
Dahlias come in a range of different sizes. The dwarf varieties can be grown as bedding, while more compact varieties grow very well in pots, while . Tree dahlias (Dahlia imperialis), from which all modern dahlias were bred, can reach 5m tall.
when to buy dahlia bulbs
You can buy dahlia plants at the garden centre in summer, but many gardeners grow them from tubers. These are potted up and brought into growth indoors in late March or early April, then planted out in the garden in May once no more frost is forecast. Dahlias can also be grown from rooted cuttings and from seed.

The taller varieties need staking. In autumn, dig up the tubers and overwinter them in a frost-free place, such as a greenhouse or a shed. Bring them back into growth in early April, then plant out in the garden from May onwards.
Dig a planting hole that's around 30cm across, and add a bucket full of well-rotted organic matter to increase soil fertility. If your soil is heavy clay, you could add some horticultural grit to the base of the planting hole, for drainage. Protect the new shoots from slugs and snails. If you're planting a dahlia bought at the garden centre, plant at the same depth they were in the pot.
Once you've planted your dahlia, you will need to provide it with some support, unless its a dwarf variety. Dahlias grow fast and have a tendency to flop, especially if the flower heads are large. Add a stout stake or bamboo canes at all four corners (these will be hidden as the plant grows). Tie the new growth in every couple of weeks.
If you're planting dahlias in a pot, choose a large container that's at least 30cm wide and deep, and fill with multipurpose compost, mixed with organic matter such as well rotted manure. You could add some slow-release plant food at the same time. Plant at the same depth as they were in their original pot.
In many parts of the country, dahlias will not survive if left in the garden over winter if it is very frosty or wet. It is therefore best to lift the tubers once the foliage has been blackened by frost. Cut the stems back to about 12cm, then, with a garden folk, gently lift the tuber and remove the soil with your fingers. Place tubers upside down in a newspaper-lined tray so that they can dry out for a couple of weeks in a dry place.
If you live in a mild area with well drained soil, or don't have the space to lift and store dahlia tubers, you can cover the soil with a thick layer of mushroom compost and/straw, to prevent frost from penetrating the tubers. In spring simply rake away the excess compost.
Slugs and snails adore dahlias, especially the new growth. Planting out plants when they are a decent size helps; as does surrounding the plant with a copper ring. You can also scatter organic slug pellets, which do not harm wildlife. Read our guide to protecting young plants from slugs.
Dahlia catalogs from a number of commercial growers will appear regularly from early-December to mid-January. These growers provide a great service for those of us who definitely desire to grow a specific variety. Many of us comb these catalogs at great length in order to structure our portfolio of garden/exhibition quality blooms. Additionally, one can visit dahlia suppliers on the internet. Supplier sites usually will include good information and pictures.
Is it a bulb? Is it a root? No, it's a tuber! Commonly referred to as "bulbs" Dahlia tubers store food for the growing season that cluster together at the bottom of a stem. Dahlia tubers can have several growing points called eyes, and can get bigger each year making more growing points. Dahlias are easy to grow, put on an amazing show all summer long, and we're proud to offer one of the largest selections anywhere!
Named for the 18th century Swedish botanist Anders Dahl, these perennial beauties are as interesting as they are beautiful. Dahlias were named the national flower of Mexico in 1963. The aztecs grew tubers as a food crop, however, the practice died out after the Spanish Conquest. Due to an enormous growth in popularity in recent years, new dahlia cultivars are being introduced regularly and we're proud to offer one of the largest selection anywhere, from the enormous dinner plates such as the Break Out dahlia to the more unusual Cactus Dahlia such as Black Narcissus. Dahlias are a genus of tuberous, herbaceous perennial plants that are native to Central America and Mexico. As members of the compositae family of plants, they are relatives of daisies, zinnias, chrysanthemum, and sunflowers! Dahlias are octoploids, meaning they have eight sets of homologous chromosomes, whereas the average plant has but two.
When growing dahlias in your yard, there are a few things to keep in mind. Dahlias really prefer warm soil and should be planted in the warm and long days of spring. Typically, you would plant dahlias when you plant your vegetable patch. You can plant dahlias as late as mid-June in most parts of the country. When selecting a planting location, seek out an area with full sun (six hours or more a day). Dahlias thrive in full sun, but can tolerate some partial shade. A general rule is the more sun, the bigger the flowers, so plan accordingly. Try to choose a location that is sheltered from the wind. One of the most vital things when planting dahlias is to choose an area that is well-draining. Dahlias do not like soggy roots.
Once you have selected the perfect location for your tubers, dig a hole that is twice as wide and deep as the tuber. Place the tuber in the hole with the eye facing up. The eye is the point on the tuber from which the plant grows. If you plan to plant multiple dahlias in the same area, be sure to separate each one by about two feet. this practice will ensure that each tuber has proper space to grow. Shorter varieties can be planted closer together. Depending on the size of the variety, rows should be about three to five feet apart. Fill the holes with just enough soil to cover the top of the tuber. Once you see new growth appear, add more soil. Slowly covering the stem with soil will allow the stem to strengthen, thus supporting the flowers better. Young dahlias do not require a lot of water. larger plants should be watered if the rainfall is less than one inch in seven days. Remove any broken or damaged foliage.
Dahlias are breathtakingly gorgeous late-season flowers that bloom from midsummer through fall in a rainbow of color. Dahlias are perennials in Zones 8 and higher; in cold climates, they need to be dug up and stored until spring. Learn how to plant dahlia tubers and great tips on how to grow dahlias!
Tubers are planted in the ground in late spring and generally flower from July to the first autumn frosts. Dahlias are perfect for a border garden and make lovely cut flowers. Growing vegetables? Put a row of dahlias on the border, where they will not shade your edibles.
Dahlias thrive in 6 to 8 hours of direct sun, especially morning sunlight, and they benefit from protection from wind. Consider their size at maturity when planting. They grow best in rich, well-draining soil with a pH level of 6.0 to 7.5. Amend heavy clay soil with aged manure or compost to lighten and loosen the soil texture for better drainage.
When dahlias are established, water 2 or 3 times a week and more in hot, dry climates. Be prepared to tend to plants before or after rain, when open blooms (especially large ones) tend to fill up with water or take a beating from the wind.
Six years ago, I bought a package of seed dahlias and planted them in an area in front of our house which is somewhat protected from the weather. The first year they bloomed and were about six inches high. Since then, they have spread over the area and bloomed on their own producing beautiful variety of colors. I have never dug them up after blooming but left them alone. The plants are 12 inches to 3 feet high. I didn't think dahlias spreads. What type of dahlias are these?
Anyone, anyone? We here at the Almanac have not tried planting/forcing dahlias early. However, the American Dahlia Society has! See the web site, -of-growing-dahlias/#::text=If%20you%20want%20blooms%20as,most%20parts%20of%20the%20country, with this specific observation: If you want blooms as early as possible, you can start the tubers indoors (fig 4) in good light about a month before planting time. You will then have a small plant ready at planting time. Dahlias can be planted as late as mid-June in most parts of the country.

Dig In With Dahlias:\r\n\r\nHow To Prepare Your Soil For Dahlias\r\nWhen To Plant Dahlias\r\nHow To Plant Dahlia Tubers\r\nHow To Stake Dahlias\r\nGrowing & Care For Dahlias Throughout The Season\r\nEnd Of Season Dahlia Care & Tuber Storage\r\nHow To Prepare Your Soil For Planting DahliasSome plants can handle any growing condition, but Dahlias really need the right conditions to produce the outstanding blooms they\u2019re known for. With a well-prepared soil bed, your Dahlias will create beautiful growth very quickly. Follow these steps for success! \r\n\r\nDahlias prefer rich and well-drained soil. Loose, nutrient-rich soil will feed tubers and encourage strong root growth. Soil must be well-draining, because Dahlias like plenty of water, but soggy soil will cause tubers to rot. Dahlias are great for sandy, loamy, or acidic soil.\r\nIf you\u2019re starting with clay soil, dry soil, or compacted soil, it will be important to make sure that you properly prepare your planting area in order to see growth and blooms. If you have challenging soil, or if you live in an area with heavy rainfall, you may want to consider growing Dahlias in berms or raised beds to create optimal conditions.\r\nEnrich your soil with compost work in a good organic fertilizer before planting. Look for a fertilizer that\u2019s low in nitrogen, to encourage blooms and not too much leafy growth. Organic material will feed your Dahlias, and help the soil to retain moisture as needed for the plants.\r\nDig at least 10 inches to 1 foot deep (or create a raised bed 10 inches to 1 foot deep) to loosen the soil and give tubers enough space to grow and to improve soil drainage. \r\nWhen To Plant DahliasGenerally, we ship your Dahlia tubers at the right time to plant! Tender Dahlia tubers are generally planted outside around the same time you plant tomatoes.\r\nIf that\u2019s not until late May or early June where you live, you can start dahlias indoors, 4-6 weeks before your last frost date. In containers, lay tubers on their sides with the stems up and cover with 2 inches of soil. Wait until you see new growth breaking through to water. Then, they can be transplanted outside when it\u2019s warm enough.How To Plant Dahlia Tubers1. First, prepare your soil as outlined above. Don\u2019t skip this step! Preparation is the key to success.\r\n2. Dig holes for planting. \r\n\r\nSpacing will vary based on your varieties. Most Dahlias are spaced with approximately one tuber per square foot. The largest varieties of Dinner Plate Dahlias will do best with wider spacing, about 12-18 inches apart, to allow for foliage and flowers to grow. Compact varieties can be planted with multiple tubers per square foot. See the spacing recommendations on your package.\r\nHoles should be relatively shallow and wide enough for tubers to be spread out, like fingers. Tubers for large varieties like Dinner Plate should be about 6 inches deep, while smaller varieties can be about 4 inches deep. \r\n\r\n3. Plant tubers.\r\n\r\nPlace tubers so that the crown (where the tubers connect) is a few inches below the surface of the soil. If there are buds, or \u2018eyes\u2019 on the tubers, place those facing up - that\u2019s where stems will grow. \r\nGently backfill soil around the tubers so that they are completely covered by a few inches of soil. There is typically some stem material at the top of the tubers, and if so, the stem can be at or just below the surface of the soil. \r\n\r\n3. Staking\r\n\r\nFor Dahlias with large flowers, and generally those growing 3 feet or taller, we recommend staking when you plant. See staking tips below.\r\n\r\n4. Watering\r\n\r\nOnce planted, give tubers a thorough soak to remove any air pockets and encourage root growth. Until they sprout, Dahlia tubers don\u2019t need much water. \r\n\r\n5. How long until they sprout?\r\n\r\nGenerally about 3 weeks - but it can take longer depending on the weather. Dahlias will sprout faster when the soil and surrounding climate are warmer, and they can be delayed or take longer when soil and weather are remaining cool. When planting in spring, and depending on your climate, they can be variable.\r\n\r\nContinue reading for growth & care throughout the season!See How To Plant Dahlias Step By StepAfter fear of last frost has passed, it's time to plant. Tubers from last summer are ready to go back into the ground.The soil for each hole is worked well, and since these are big dahlias, a stake is put into place early on.We're planting three clumps of tubers per hole. (Each will result in a large plant.)Our large dahlia garden is planted and fertilized. Now all we need is regular watering and a few weeks.About two weeks after planting, the beautiful foliage is up and growing.Soon after the foliage appears, buds follow. They're small now, but will soon expand into bloom.By mid-summer, plants are about 2 1\/2 feet tall, and first flowers are open. Buds are everywhere!A few weeks later, plants are full grown at about 4 feet, and all this color will continue until frost.How To Stake DahliasIf you're growing big Dahlia plants, staking will be important. We recommend being pro-active, and setting up your stakes when you plant your Dahlia tubers. The beautiful foliage grows on somewhat brittle stems, and heavy rain, wind, or even the weight of the flowers once they've opened can break the plant. You don't want that to happen, especially at bloom time!\r\n\r\nSet one or two stout stakes beside each tuber after you plant them.\r\nWooden stakes can be buried or hammered in. Metal stakes can be placed in the soil more easily and are a great option if you find that your Dahlias need a little extra support after they've grown in. \r\nHave the twine or 'twist-ems' ready to support the stems as they grow.\r\n\r\nWith a little effort, the stakes will be completely hidden by the leaves, but you will thank yourself when your big, beautiful flowers a growing with support.Stakes can be placed at planting time.Or, stakes can be placed after plants have grown in.Growing & Care For Dahlias Throughout The Season Growth Habit\r\nDahlias grow quickly, producing bush plants and flowering in the first season. \r\nWatering Dahlias\r\nWater regularly, and try to keep your foliage dry. Avoid overwatering, as soggy soil can lead to rotting tubers. We recommend less frequent, but deep watering. \r\nIt\u2019s best to let the soil dry out between watering, as soggy soil can easily cause tubers to rot (remember - that\u2019s why good soil preparation is so important). Water thoroughly about once per week until Dahlias sprout. \r\nOnce you see top growth, water as needed when soil has dried out. As the plant starts to grow and temperatures increase with the start of summer, you may need to water more often. If you\u2019re experiencing regular rainfall, you may not need to water if your soil is not drying out. \r\nWhen watering, keep water near the soil surface, and avoid getting leaves wet to help prevent diseases. Water slowly and deeply to give the soil a thorough soak.\r\nFertilizing Dahlias\r\nLook for a fertilizer that is high in potassium (K) and phosphorus (P) but low in nitrogen (N). Potassium and Phosporous encourage bud growth and flowering. to prevent leafy bushes with few blooms. Check your NPK (Nitrogen-Phosporous-Potassium) levels in your fertilizer before you purchase. Expert growers recommend formulas such as 5-10-10, 10-20-20, or even 0-0-10. Fertilizing dahlias just a couple of times can make a big difference to the flower yield. Add when planting, and once a month at most before flowering begins. \r\nMulching Dahlias\r\nIn very hot, dry areas, you may want to mulch to help retain moisture, but in most areas, we recommend skipping mulch so that the soil can stay warmer and foliage can stay dry.End Of Season Dahlia Care & Tuber StorageIn the right conditions, Dahlias can overwinter in the garden in zones 8-11. They need well-drained soil and dislike wet winters. In colder zones with winter frost and freeze, Dahlias won't survive after frost.\r\nSome gardeners will treat Dahlias as annuals, re-planting new tubers each spring. You can also dig up your tubers and store them for the winter in a cool, dry, dark place, then re-plant them the following spring.For more detail on storing dahlia tubers, Learn More: How To Dig and Store Dahlias For The SeasonWatch: All About Dahlias\r\n\r\n\r\n\r\n\r\nReady To Dig In?
