Lotosimassa on vaid ĂĽks viis, kuidas dahlia kroonlehed olla struktureeritud.

Kasutatav nii lillede kui lõikelillega on dahlia (Dahlia spp.) Pärit eri kuju, suuruse ja värvusega. Naiste keskosa Mehhiko, need lilled eelistavad täis päikesevalgust ja niiske, rasune ja hästi kuivanud pinnas. Nad kasvavad maa-alal Ameerika Ühendriikide põllumajandusministeeriumi taimede vastupidavuse tsoonides 8 kuni 11 ja te saate mugulad üles kaevama ja neid hoida, kui elate külmemas kliimas. Need tingimused, aga ka evolutsioonilised eelised dahlia tuberose juurtes, võimaldavad nautida nende taimedega üllatavat mitmekesisust.

Juurstruktuur

Dahlia on kahepalgeline ja sarnaselt teistele kahekohalistele taimedele on juured, mis ei sõltu ühest, kesksest juurest ega taprootst. Juured on nii iseseisvad, et saate paljundada tütarettevõtet, lõigates ära osa täiskasvanud taime juurest protsessis, mida nimetatakse jagunemiseks. Seda seetõttu, et dahliajuurede juured sisaldavad kogu geneetilist materjali ja energiat, mis on vajalik uue taime juurtest mugulate alustamiseks. Juustujuure jagatakse tükeldamise teel. Veenduge, et igal jaotatud juurusüsteemil oleks aktiivne pung või silm, mis paneb istutatud uue lille. Lisaks on dahlia lihavad mugulad söödav ja neid kasutatakse mitmes Mehhiko roogas.

Lillstruktuur

Mitmed dahlia liigid erinevad kuju ja kujunduse poolest, pakkudes aia jaoks erinevaid kujundeid ja värve. Üksikud õitsvad kariloomad, nagu orhidee õitsemine, singli- ja anemoneeliigid, sisaldavad üks rida küüslauku ümber pistiläpi ja sisaldavad lilli, mille läbimõõt on kuni 4 tolli. Kahekordsed õietaimed, sealhulgas torukujulised kaktusdahlia ja kuulipulgad, sisaldavad mitmeid kroonlehtede ridu ja sisaldavad sageli lilled, mis on suuremad kui 4 tolli.

Juurprobleemid

Hoolimata dahliajuurte juurstruktuuri eelistest, on neil teatud probleemid altid. Dahlia juurtele on huvitatud mitmed mikroorganismid ja nakkuslikud bakterid. Juureõlme nematood leiab oma juure mulda läbi ja põhjustab juurte turset ja põlemist. Crown gall, nakatavad bakterid võivad istuda mullas kuni kolm aastat, oodates dahlia tuberous juuri. Kui nakatunud, kahjustavad dahliajuure juured ja varred ebamugavusi, mis on nn galls. Pinnase steriliseerimine enne kasutamist tavaliselt eemaldab need probleemid.

Lilleprobleemid

Dahlia lilled on ka vastuvõtlikud kahjuritele ja nakkusele. Hallikasvand nakatab kariloomade kroonlehed, pruunib kroonlehed esimest korda, tapab need ja muudab need halli halli hallituse toitu. Lehtpuud, lehtkapsad, kibuvitsad ja caterpillarid on ka dahlia jaoks tavalised probleemid ja võivad lillele mõjuda.

Dahlias Roots & Flowers

FAQ - 💬

❓ What kind of roots do dahlias have?

👉 Dahlia plant becomes into the Asteraceae family of fibrous, bushy, herbaceous perennial plants. They have fibrous roots. The roots arise from a point and grow in clusters helping in storing food during the perennation via converting into the tuft of tubers.

❓ How many dahlia flowers do you get from one tuber?

👉 How many dahlia plants can I get from a tuber? 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).

❓ Do dahlias have roots or tubers?

👉 A dahlia tuber is a tuberous root of a dahlia plant. It is a starchy body that contains food, water, and nutrition for a dahlia plant to grow until it establishes a root system that will then provide food for the plant.

❓ What are dahlia roots called?

👉 Even though they're often called bulbs, the roots of Dahlias are actually tubers (as in tuberous begonia). Dahlia tubers look a lot like a bunch of brown carrots, and the stems sprout directly from the tubers.

❓ Can dahlias grow in pots?

👉 Dahlias are usually started in pots undercover and then planted out in the garden, however it is possible to grow dahlias in a pot. Make sure you choose a slightly compact dahlia variety, as some dahlias can grow over 1.5m (5ft) tall.

❓ What happens if you don't divide dahlias?

👉 Each plant will produce a clump of new tubers which, undivided, will produce smaller plants with poorer quality blooms. Eventually the plant will become so congested and the results so poor that it should be lifted and divided.

❓ Do dahlias multiply?

👉 Dahlia plants produce tubers that grow in the ground. Each year the mother tuber (the original bulb) typically produces anywhere from 5-20 new tubers. By dividing these tubers in the winter, you can multiply the original plant and grow identical dahlia flowers.

❓ What month do you plant dahlia tubers?

👉 Dahlia tubers can be started into growth in March or April in pots undercover, and then planted out in the garden in late May and June. Start by half-filling a 2 or 3 litre pot with peat-free multi-purpose compost. Place the tuber in the pot with the central stem upwards and cover with more compost.

❓ How do you wake up dahlia tubers?

👉 As you get towards spring and are ready to start planning your garden or farm season, we recommend pulling your tubers out of storage and waking them up by bringing them into a warmer environment with temperatures in the 60s two weeks before planting.

❓ Can I leave my dahlias in pots over winter?

👉 Once late Autumn hits and the first frosts arrive, it's a good time to bring your potted Dahlias inside for storage over the winter. You will need some secateurs and, if you have a fair few pots, possibly some crates for storage.

❓ How big do pots need to be for dahlias?

👉 12- to 14-inch diameterPlanting in Pots For most dahlias, you want a fairly large pot, though it doesn't need to be very deep. Many varieties would do well in a 12- to 14-inch diameter pot which is also at least 12 inches deep. Also, make sure the pot has good drainage because the tubers will rot if left to sit in water.

❓ Do dahlias have deep roots?

👉 If you want to add dahlias to your collection of flowers this year, try planting the roots. Dahlia roots put down deep roots, which means they’re sturdy plants that come back year after year if you take care of them. Prepare a site with full sun and well-drained soil. Dahlias grow best in rich, loose soil that is approximately 12 to 18 inches deep.

❓ What is a dahlia plant?

👉 Dahlia is a genus of tuberous plants that are members of the Asteraceae family; related species include the sunflower, daisy, chrysanthemum, and zinnia. They grow from small tubers planted in the spring.

❓ Can you plant dahlias with other plants?

👉 Large dahlias and those grown solely for cut flowers are best grown in a dedicated plot in rows on their own, free from competition from other plants. Dahlias of medium to low height mix well with other summer flowers.

❓ How do you get dahlias to bloom again?

👉 Remove the main shoot (in the centre of the plant, growing upright) down to the top pair of leaves, using a sharp knife or your thumb and forefinger. Tie in new growth to the stake every week or so. Once a fortnight, feed your dahlias with a high potash feed, such as tomato feed. This keeps the flowers coming.
